The Next Evolution of Grid Defense: Comparing ForeScout’s Visibility Approach with Preemptive Cyber Defense

Introduction

Securing a large, distributed enterprise – especially one operating critical Operational Technology (OT)/Industrial Control Systems (ICS) – requires a solution that balances broad visibility, robust threat prevention, and cost-effectiveness. Two contenders in this space are Forescout and PacketViper, each with different approaches. This comparison examines their technology differences, benefits, costs, and overall “bang for the buck” for an organization with ~1,000 remote sites (a scale common in large utilities or energy companies). The focus is on on-premise deployment in both enterprise IT and OT/ICS environments, with consideration for cloud-connected components (e.g. PacketViper’s AlertBox service for cloud-based alerts).

Forescout Overview (Enterprise & OT/ICS)

Forescout is best known for its Network Access Control (NAC) and device visibility platform. It provides an agentless solution to discover and classify devices across IT and OT networks. In an enterprise setting, Forescout’s platform (now the Forescout 4D Platform) encompasses modules like:

  • eyeSight for continuous device visibility and asset inventory
  • eyeControl/eyeSegment for policy-based access control and network segmentation (e.g. dynamic VLAN assignment)
  • eyeInspect (formerly SilentDefense) for passive ICS network monitoring and anomaly detection in OT networks.

Forescout shines in asset intelligence and compliance. It can identify a wide range of devices – from IT endpoints to IoT and industrial devices – and assess their security posture. This broad coverage helps organizations meet regulations (for example, electric utilities can use Forescout to inventory OT assets for NERC CIP compliance) and implement Zero Trust principles by profiling and controlling every device on the network. Forescout is typically deployed centrally: it monitors network traffic (via switch SPAN ports or APIs) and can orchestrate controls by integrating with network infrastructure (switches, firewalls, etc.) to quarantine or segment non-compliant devices. Crucially, Forescout’s approach is mostly passive/agentless, avoiding software agents on endpoints (though an optional agent exists for certain use cases).

In OT environments, Forescout’s eyeInspect offers deep packet inspection for industrial protocols and ICS threat indicators. It passively monitors SCADA/ICS traffic to detect anomalies or known threat patterns, providing alerts on potential attacks or unsafe device behavior. However, Forescout’s built-in response in OT tends to be limited to alerting or integrating with other tools – it “barks” but often relies on other systems to “bite,” as one analysis notes about pure OT monitoring tools. Forescout compensates with rich data and integrations: it can feed OT asset and threat data to SIEMs and support workflows for incident response, but automated containment of threats is not its primary strength in ICS. Its value is in giving security teams a “single pane of glass” visibility of IT and OT together.

Key benefits of Forescout include: comprehensive device visibility across domains, a mature policy engine for access control, and strong compliance reporting. It is often chosen by large enterprises for broad network visibility and NAC capabilities. In an environment of 1000 distributed sites, Forescout could provide centralized monitoring of all connected devices if networks are linked, helping identify rogue or unmanaged devices in any location. However, fully leveraging Forescout in remote or air-gapped sites may require network connectivity or deploying multiple appliances – a potential challenge for very distributed operations (remote substations, etc.).

PacketViper Overview (Enterprise & OT/ICS)

PacketViper takes a different, deception-driven approach to security, purpose-built for critical infrastructure protection. PacketViper’s solutions (e.g. OT360™ and OTRemote™ for OT, and IT360™/Deception360™ for IT) combine active threat detection, in-line prevention, and response in one platform. Rather than focusing primarily on device compliance, PacketViper emphasizes dynamic defense: it uses lightweight decoys (“deceptive responders” and “deceptive transmitters”) and policy enforcement to engage and block threats in real time. This proactive stance means PacketViper not only detects suspicious activity, but immediately contains it by misleading attackers and cutting off malicious traffic at “wire speed”.

PacketViper’s architecture is well-suited to distributed, even isolated sites. It deploys Remote Security Units (RSUs) – essentially on-premises appliances or virtual units at remote locations – which can function autonomously without constant connectivity to a central manager. This is ideal for an organization with many unmanned sites (e.g. pumping stations, substations, remote plants): each site’s PacketViper appliance can locally monitor OT network traffic, deploy decoys, and enforce blocking, even if the link to headquarters is down. PacketViper correlates physical signals with cyber events when sensors are integrated – for example, detecting a physical intrusion (motion sensor triggered) combined with unusual network scans, and responding instantly. This cyber-physical awareness is a unique capability that bridges physical security and cybersecurity for a 360° view.

Notably, PacketViper’s solution is agentless and can be deployed out-of-band (monitor mode) or in-line. In monitor mode, it operates like a high-fidelity IDS with deception, raising alerts without risking operations. When confidence is gained, it can be moved in-line to actively “shoot down” threats as they occur. Its deceptive elements (decoy services, fake network traffic via Deceptive Transmitters, etc.) lure attackers into engaging fake assets, upon which PacketViper automatically blacklists or contains the threat source. This stops malware or attackers before they reach real systems, reducing dwell time and lateral movement. PacketViper also provides traditional network controls like geo-fencing (country-based traffic filtering) to reduce noise and unwanted traffic – a feature inherited from its origins in network filtering technology.

For OT/ICS, PacketViper supports industrial protocols and offers SCADA integration (e.g. Modbus awareness). It understands OT traffic patterns and can generate contextual, policy-based alerts without using signatures. The platform enforces a form of Zero Trust for OT, allowing only pre-approved communications and using deception to catch anything outside the norm. In essence, PacketViper serves as an inline security stack at each site: performing traffic filtering, intrusion deception, and segmentation locally. It thereby maintains availability of ICS processes by stopping attacks while permitting legitimate operations to continue.

Key benefits of PacketViper include: active threat prevention (not just monitoring), autonomous operation at remote sites (ideal for air-gapped or hard-to-reach locations), and a unified solution that covers multiple security layers (network filtering, deception, and response). PacketViper touts that it eliminates false positives and only alerts on genuine malicious activities by virtue of its deception approach – which means less noise for security teams. It also offers granular visibility into OT network traffic, including proprietary industrial protocols, achieving insights many competitors can’t match without specialized tools. For an enterprise with 1000 locations, PacketViper’s scalable design allows deploying a small appliance per site, centrally overseen (with AlertBox cloud service aggregating alerts). This distributed model ensures even isolated sites are protected in real-time, with low bandwidth dependence.

Feature and Technology Differences

1. Security Approach – NAC vs. Deception/Prevention:
Forescout primarily acts as a NAC and monitoring platform, excelling at identifying devices and ensuring only authorized, compliant devices connect to the network. It enforces policies like network segmentation and can quarantine suspicious or non-compliant endpoints (e.g. an unauthorized laptop) via switch/control integrations. However, Forescout by itself does not deploy honeypots or decoys to engage attackers. Its OT security module (eyeInspect) is passive, meaning it will detect and alert on malicious patterns but generally won’t directly block network traffic on detection (integration with firewalls or manual intervention is needed for response). This reactive stance means threats might still require human or additional tool intervention to neutralize.

PacketViper’s approach is more offensive/active. It uses deceptive techniques and automated containment as core features. When an unknown or suspicious actor scans or interacts with a decoy system, PacketViper immediately takes action – for example, engaging the actor in the decoy environment and simultaneously blocking that source across the network (“dynamic containment”). PacketViper’s philosophy is to preempt threats by tricking and trapping them, whereas Forescout focuses on identifying assets and issues so administrators can respond. In short, Forescout is akin to a security guard identifying intruders, while PacketViper is more like a security system that automatically traps the intruder as soon as they try something malicious.

2. Visibility and Asset Management:

Visibility is a strength of Forescout – it provides a “single pane of glass” inventory of all IP-connected assets (IT, IoT, OT, etc.) on the network. It can profile devices by type (manufacturer, model, OS, etc.) using active querying and passive listening. For a large enterprise, this means a continuously updated device database, which is valuable for IT governance and compliance. Forescout also offers extensive compliance checks (e.g. is a device running required patches or security software) and can trigger notifications or access restrictions if policies are violated. This kind of IT hygiene enforcement is something PacketViper does not explicitly focus on – PacketViper isn’t scanning devices for vulnerabilities or checking software versions.

PacketViper’s visibility is centered on network behavior and threats. It gives granular insight into network traffic patterns, both inbound and outbound, and across OT-specific protocols. It also correlates physical events with cyber events to enrich situational awareness (for example, showing that a physical access event coincided with a network scan at the same site). While PacketViper can discover assets by observing network traffic (and even perform asset discovery in OT without active scanning), it may not maintain the same rich device inventory or compliance data that Forescout does. Instead, PacketViper’s visibility advantage is seeing malicious activity that would be invisible to normal asset-centric tools – e.g. an attacker quietly performing reconnaissance appears as “low-and-slow” noise to most systems, but PacketViper’s decoys would catch that behavior early. PacketViper also provides geographic visibility, showing where traffic is coming from/going to and allowing geo-fencing (useful for OT networks that should only talk to known regions).

In summary, Forescout provides broader asset visibility and IT system insight, whereas PacketViper provides deeper threat visibility and contextual network insight (especially in OT networks). Many enterprises might use Forescout for asset management and PacketViper for threat hunting/prevention – PacketViper is essentially adding a deceptive defense layer that Forescout lacks.

3. OT/ICS Capabilities:

Both solutions recognize the special needs of OT/ICS security, but they tackle it differently. Forescout’s OT module (eyeInspect) covers OT protocol detection, asset inventory in ICS (identifying PLCs, HMIs, etc.), and threat detection based on known ICS attack signatures or anomalies. It supports compliance use-cases (like producing network diagrams and asset lists for audits) and has integrations to feed data to SOC tools. However, as Forescout’s own competitive material notes (in comparing to an OT-specific tool, Dragos), a narrowly focused OT monitor can require “extensive fine-tuning and result in a higher total cost of ownership” for full coverage. Forescout pitches itself as covering both IT and OT in one platform – useful for organizations bridging those environments.

PacketViper is purpose-built for OT environments and emphasizes safety and reliability in how it operates. It is designed to run in sensitive ICS networks without causing disruptions: it avoids active scanning (which can crash fragile PLCs), and it’s deployed either out-of-band or in-line in ways that won’t interfere with critical process traffic unless truly necessary. PacketViper also offers features unique to OT settings, such as Airgap Mode (ensuring a site remains secure even if disconnected from any central management) and Modbus integration (understanding specific OT commands to catch suspicious use). Additionally, PacketViper’s use of “industrial-grade hardware” for its appliances means they are built to withstand harsh environmental conditions often found at utility sites (extreme temperatures, dust, etc.). This is contrasted with Forescout, which typically runs on standard appliances or VMs that might reside in data centers; deploying those directly in the field at 1000 substations would be less practical.

A major OT security difference is prevention vs detection: PacketViper’s ability to actively contain ICS threats (like isolating a malware-infected HMI by engaging it with decoys and cutting its connections in real time) provides a safety net against fast-moving attacks. For instance, if malware begins scanning an OT network, PacketViper decoys will trick it and block its source immediately, potentially stopping a scenario like the Oldsmar water plant attack in its tracks before any valve settings are changed. Forescout, on the other hand, might raise an alert about abnormal OT commands or an unknown device on the network, but stopping that attack would rely on either pre-configured NAC policies or a manual response. In OT, where every second counts to prevent physical damage, this difference is significant.

4. Deployment & Scalability (1,000 Locations):

For an organization with around a thousand sites, deployment practicalities and scalability are crucial. Forescout’s deployment typically involves a central management console and distributed appliances or sensors. Forescout appliances (e.g. CounterACT CT-series) come in different capacities (for example, a CT-1000 appliance supports ~1,000 devices. Very large environments often require multiple appliances plus an “Enterprise Manager” for coordination. In a scenario with many remote sites, Forescout could be deployed in a hub-and-spoke model: regional appliances monitoring traffic from clusters of sites, or a virtual appliance in each network segment. However, truly isolated sites (with no continuous WAN connectivity) pose a challenge – Forescout wouldn’t be able to monitor an air-gapped site in real time unless an appliance is on-site and data is later synced. Also, the network infrastructure requirements for NAC (such as managed switches that Forescout can control, or 802.1X capability) must be in place at each location for full functionality. If some of those 1,000 sites are legacy OT with minimal network gear, Forescout’s policy enforcement could be limited there.

PacketViper’s deployment is inherently decentralized and scalable across many sites. Each site gets a Remote Security Unit (a small appliance or VM). These RSUs are designed to be plug-and-play in OT environments, often alongside existing network switches or as a bump-in-the-wire. Because PacketViper’s model is “zero orchestration” (each unit can function independently), sites can even be offline or disconnected and still protected. A cloud-based AlertBox or central console can aggregate alerts from all units for a unified view, but even if connectivity to a site is lost, that site’s RSU continues enforcing security policies locally. This suits a widespread deployment – essentially linear scalability as you add more sites. PacketViper also boasts an enterprise-wide orchestration capability for critical events: if a new threat is discovered at one location, a central authority can push a rule to all 1000 locations at once (e.g. block a malicious IP or implement a new decoy). This kind of rapid, distributed response is harder to achieve in a traditional NAC setup. In short, for 1000 locations, PacketViper’s distributed model offers simplicity and resilience, whereas Forescout’s centralized model may require significant network integration effort but provides a unified policy framework for connected sites.

5. Security Stack Coverage (“Bang for the Buck”):

One way to evaluate “bang for the buck” is to consider how many security functions each solution provides versus what you’d otherwise need to buy or implement. In that sense, PacketViper can replace or reduce the need for multiple tools: it acts as a network intrusion detection system, an intrusion prevention system, a deception platform, and even performs some firewall/geo-filtering and micro-segmentation roles – all in one integrated system. It also incorporates rudimentary OT SIEM/SOAR capabilities by correlating and responding to events automatically. This comprehensive feature set is highlighted by PacketViper’s internal comparisons: it offers containment, deceptive responders, moving-target defense, geo-targeting, vendor access management, and remote-site protection in one product – features that no single competitor covers collectively. For example, none of the compared competitors (a list including Claroty, Nozomi, Dragos, Canary, etc., and Forescout) provide built-in deception or active containment the way PacketViper does. This means an enterprise using PacketViper is getting a “stack” of capabilities that would otherwise require deploying a NAC, plus a deception system, plus perhaps an ICS intrusion detection system – potentially three separate products – along with the integration effort among them. PacketViper delivers these in a unified manner, which can translate to cost savings and operational simplicity.

Forescout, on the other hand, covers the NAC and visibility layer extremely well, but does not natively include things like honeypots or external threat deception. To match PacketViper’s breadth, a Forescout deployment might be complemented with additional tools: e.g. using a third-party deception platform (like Illusive or Attivo/Armis) for decoy functionality, and possibly an ICS-specific IPS for active blocking in OT. Forescout’s platform does integrate with many other security tools – in fact, integration is a selling point (the Forescout Marketplace boasts lots of third-party integrations) – but those represent extra investments. So, when it comes to “security stack” completeness per dollar, PacketViper provides more layers out-of-the-box.

That said, an organization that already has a mature security stack might leverage Forescout to tie things together. Forescout can feed data to SIEMs, trigger actions on firewalls, and coordinate with endpoint security – serving as a central brain for device-centric security. If those systems are already bought and paid for, Forescout adds value by enhancing their efficacy (for instance, telling a firewall to block a device that Forescout identified as infected). PacketViper’s value is greater when an organization needs to fill gaps in prevention capabilities; it’s particularly attractive for OT-heavy enterprises that lack on-site security staff at every location – PacketViper will autonomously handle threats that slip past perimeter defenses, acting as a force multiplier for a small security team.

Cost Comparison and ROI Considerations

Licensing Model: Forescout is typically licensed per the number of devices (endpoints) under management. For example, a 1-year license for 1,000 endpoints of Forescout (including support) has been listed around $27,000. Appliances or virtual machines are an additional cost (physical appliances start at ~$5,000 and up, depending on capacity ). Large deployments (tens of thousands of devices) can run into high six or seven figures over multi-year periods, once you include modules for OT monitoring, maintenance, and support. In our 1,000-site scenario, if each site averages, say, 50 devices, that’s 50,000 devices total – licensing that many endpoints could cost on the order of $1M+ per year just in Forescout software (50 * $27k for 50k devices, roughly) before volume discounts. Forescout’s Total Cost of Ownership (TCO) also must factor in the infrastructure (you may need multiple Forescout appliances or VMs for load distribution), and the integration effort (time to configure network equipment for NAC, tuning the policies, etc.).

PacketViper uses a subscription-based model that is site-focused rather than device-focused. Instead of charging per endpoint, PacketViper generally charges per deployed appliance/RSU and includes all features for that site. Notably, PacketViper’s subscriptions include the hardware/appliance cost – it’s a “Zero CapEx” model where the customer doesn’t buy the hardware outright; it’s bundled in the subscription fee. This means for 1,000 locations, a PacketViper solution would involve 1,000 RSUs, but the customer isn’t paying 1,000 separate hardware purchases upfront. They would likely sign a multi-year contract (3, 5, or 7 years are offered) and pay an annual or monthly fee per site. Precise pricing isn’t publicly disclosed, but PacketViper markets itself as an “affordable” OT security option, aiming to be cost-effective enough to deploy widely. The inclusion of ruggedized switches and cellular/Wi-Fi gateways in some packages suggests PacketViper is positioning as a one-stop solution for remote sites – potentially saving the cost of additional networking gear at those sites.

Cost Avoidance: Beyond direct pricing, it’s important to consider how each solution might help avoid other costs:

  • Avoiding Breaches and Downtime: In critical infrastructure, a cyber incident can cause costly downtime or safety incidents. PacketViper’s focus on preventing incidents (by stopping attacks early) can yield huge savings by averting production outages or compliance violations. By automatically containing threats that would otherwise spread, PacketViper reduces the chance of a minor intrusion escalating into a major breach. This proactive defense could translate to avoided costs in the form of lost revenue, recovery expenses, or regulatory fines. Forescout also helps avoid incidents, but more indirectly – by identifying vulnerable devices or suspicious behavior, it enables response before an incident worsens. However, if an attack occurs rapidly (like ransomware propagating through OT networks), Forescout’s alerts alone might not stop it in time, whereas PacketViper might halt it. Thus, PacketViper may provide better insurance against high-impact attacks, which is a meaningful ROI factor (one industry study on deception tech noted rapid return on investment when attacks are prevented within the first year).
  • Reducing Tool Redundancy: As noted, PacketViper can replace multiple tools (IDS, deception, some firewall rules, NAC-lite functionality). This consolidation can avoid the cost of purchasing and maintaining separate systems. For an organization considering both Forescout and, say, a deception system, choosing PacketViper could cover both needs. On the flip side, Forescout might eliminate the need for a separate asset management database or certain vulnerability scanners (since it can check device hygiene). Each solution can reduce certain expenditures: Forescout might let you avoid hiring additional IT asset auditors or reduce manual compliance efforts, while PacketViper might let you avoid paying for managed detection and response services because it already catches threats internally.
  • Operational Efficiency: Forescout can streamline network access management – for example, reducing labor in onboarding devices or doing network audits, which is a cost saving (IT teams spend less time chasing down rogue devices or updating spreadsheets). PacketViper can reduce the analyst workload by cutting down false positives and only alerting on genuine threats. By automating containment, it also saves the incident responders’ time (the “respond” action happens automatically, so the team can focus on investigation and remediation rather than scrambling to isolate machines). Both solutions thus can reduce personnel costs in different ways.
  • Deployment and Maintenance Costs: Forescout’s NAC deployment in 1000 locations could be a substantial project – configuring network gear, ensuring each site’s equipment is compatible, etc. If not already budgeted, that’s an indirect cost (or risk, if misconfiguration occurs). PacketViper’s deployment at each site is relatively self-contained (drop in the appliance and go), which might be less costly in terms of professional services or installation effort. PacketViper’s appliances are also low-touch; since they run autonomously, they might not need continuous tuning once policies are set. Forescout deployments often involve ongoing tuning (updating classification scripts for new devices, adjusting policies as the network changes). Depending on the environment, one or the other could have higher admin overhead. Generally, NAC solutions like Forescout are known for their initial complexity, which can inflate cost if external consultants or extended timelines are required. PacketViper’s user-friendly approach for OT (built to “set and forget” to a degree) could be a cost advantage in environments with limited IT staff on site.

In concrete terms, if we assume PacketViper charges per site per year, and considering it markets itself as affordable, the total cost for 1,000 sites might be competitive or lower than a full Forescout deployment for equivalent coverage. For example, one could estimate PacketViper at a few thousand dollars per site per year (which would be on the order of a few million annually for 1000 sites). While that is still significant, it includes hardware and a breadth of protection. A Forescout solution covering tens of thousands of devices with add-ons for OT monitoring could also reach a similar multimillion figure; however, the value per dollar leans in PacketViper’s favor if those dollars are securing critical OT systems that otherwise might require multiple disparate tools.

Which Offers More “Bang for the Buck” and Visibility?

Overall Security Value: For a large enterprise with substantial OT, PacketViper delivers a more comprehensive security stack per dollar spent. It provides multiple defensive layers (deception, filtering, containment) in one platform, potentially reducing the need for additional products. Its subscription model with included hardware also reduces capital expenditure barriers, making it easier to scale to many sites. PacketViper’s unique capabilities (e.g. dynamic threat containment and attacker engagement) directly contribute to risk reduction, which is a tangible value in environments where a single incident can cost millions. When measuring “bang for the buck” in terms of risk mitigated vs. cost, this proactive defense can yield high ROI – the solution essentially pays for itself if it prevents even one major incident. Furthermore, PacketViper’s focus on OT means that dollars spent here are highly tuned to protecting critical operations, which often have a higher value-at-risk than typical IT assets.

Forescout, while not as singularly focused on active threat prevention, provides excellent value in visibility and control of the enterprise environment. Its strength is that it can function as a foundational security layer – seeing every device, enforcing network access rules, and integrating with many other tools. Organizations that need to get a handle on “what do we have on our network?” and ensure compliance will find Forescout invaluable. The visibility Forescout offers is broader than PacketViper’s: for pure asset inventory and IT governance, Forescout may give more bang for the buck because it can prevent incidents like rogue devices connecting or non-compliant systems creating vulnerabilities, problems that deception alone might not solve. So if the metric is coverage of assets and compliance per dollar, Forescout is a strong contender – it’s like an insurance policy that keeps your house in order. However, some might argue that asset visibility (while important) doesn’t directly stop cyber attacks; it’s necessary but not sufficient. PacketViper more directly stops attacks, which can be seen as delivering more immediate security value per dollar in high-threat environments.

Visibility Comparison: In terms of visibility, it’s somewhat a trade-off of breadth vs. depth. Forescout provides breadth – visibility into everything connecting to the enterprise/OT networks, often in real time, with details like device type, OS, user, location, etc. A security team gains a holistic understanding of their networked ecosystem with Forescout (often uncovering devices they never knew about, which is valuable). PacketViper provides depth of visibility into threat activity – it shines a light on the subtle network behaviors and potential intrusions that other tools might miss. PacketViper also increases visibility into remote sites that might otherwise be “dark.” For instance, if a remote ICS site is normally quiet, a Forescout system might just report “here are 5 devices, all good.” PacketViper at that site might reveal that once a week there are strange connection attempts or scans hitting a decoy, indicating an ongoing attack campaign – insight you wouldn’t have without a deception element. PacketViper also adds visibility into the interaction between physical events and cyber events (like the earlier example of a door opening and a network scan coinciding), which is a unique dimension of situational awareness.

For a company operating critical infrastructure, the ideal scenario could even be to use both: Forescout as the overarching visibility and access control layer, and PacketViper as the inner security layer for threat engagement and prevention. But if a choice must be made, organizations heavily leaning on OT security and threat prevention might find PacketViper gives more value (since it addresses the pressing need of stopping attacks on critical systems), whereas organizations whose priority is network hygiene and visibility might start with Forescout.

Conclusion

In comparing Forescout and PacketViper for a large enterprise with OT/ICS operations, both solutions bring strong capabilities but in different areas. Forescout offers comprehensive device visibility, network access control, and integration-friendly policy enforcement, which can greatly improve an organization’s security baseline and compliance stance. PacketViper offers an aggressive security posture with deception-driven threat prevention, automated containment, and tailored support for distributed critical infrastructure. For a 1,000-location scenario in OT/ICS, PacketViper’s distributed, autonomous approach is a natural fit and likely provides a greater “bang for the buck” in security outcomes – it delivers a wide security stack and reduces the likelihood of costly incidents. It also aligns with tight budget or resource situations by being easy to deploy and affordable at scale.

Forescout, meanwhile, could be seen as providing cost avoidance in different ways – preventing unauthorized access and ensuring compliance can save money by avoiding fines or breaches caused by unmanaged devices. If budget allows, Forescout’s broad visibility combined with PacketViper’s deep prevention would be a defense-in-depth ideal. But if we ask “which gives more security stack and visibility for each dollar?”, PacketViper has the edge in directly bolstering the security stack (with multiple capabilities in one) and offering rich threat visibility, whereas Forescout excels in asset visibility and access management, which are foundational but may require additional layers to stop advanced threats.

Ultimately, the choice may come down to an organization’s immediate needs: For maximizing security outcomes in an OT-heavy enterprise with limited security manpower, PacketViper offers a compelling value proposition. It actively defends remote sites and critical networks in real-time without constant human intervention, delivering a high level of protection and situational awareness per dollar spent. Forescout remains a powerful platform for those who need to see and control everything on their network, and its value in maintaining a clean and monitored network environment is undeniable – but to get the “biggest bang” in terms of thwarting sophisticated attacks and covering gaps in the security stack, PacketViper provides an integrated solution that can be more impactful in the context of enterprise + ICS security .
