Are We Already Breached?
Your operations are a “black box”—and you don’t know who’s looking in. PulseCheck™ delivers on-demand threat hunting for critical infrastructure specifically designed for operational technology environments. We find the threats hiding in your controllers, SCADA systems, and industrial networks—without risking a single second of downtime.
You Can't Secure What You Can't See
Most critical infrastructure operators face a dangerous reality:
Your IT team protects email and office computers. But who’s watching the controllers, pumps, and SCADA systems that actually run your operations?
Standard IT security tools are blind to OT. Worse, they’re often too aggressive—a standard network scan can crash sensitive PLCs and halt production.
Threats hide in industrial protocols. Attackers know that Modbus, PROFINET, and DNP3 traffic isn’t monitored. They use your own operational protocols against you.
You’re operating on hope, not knowledge. Most facilities rely on outdated spreadsheets to track equipment. You have no real-time visibility into what’s on your network or who’s accessing it.
The Cost of Not Knowing
For Water & Wastewater
- SCADA compromise = public health emergency
- Treatment process disruption = regulatory violations
- Unauthorized access = EPA/AWIA compliance failures
For Manufacturing
- Production line shutdown = $100K-$500K per hour
- Supply chain disruption = customer penalties
- Safety system compromise = worker safety risk
- Intellectual property at risk
For Energy & Utilities
- Generation control failure = grid instability
- Distribution network compromise = community-wide outages
- NERC CIP violations = substantial fines
For Municipal Operations
- Emergency services disruption = public safety crisis
- 911 system failure = liability exposure
- Public works shutdown = community impact
PulseCheck
The 72-Hour Forensic Threat Hunt
A PulseCheck is a high-intensity, short-duration forensic engagement. We deploy our proprietary Garrison Sentry node into your environment to capture and analyze raw network traffic. We don’t ask your tools what they see—we ask your network what it is doing.
The Three Core Discovery Pillars
1. The Ghost Asset Map
We identify every device on your network, including unmanaged “shadow” IT, legacy systems, and unauthorized vendor connections. If it has a heartbeat, we find it.
2. Lateral Movement & Exposure
We map how an attacker would move through your network. We identify the pathways from low-security areas (Guest Wi-Fi/Workstations) to your “Crown Jewels” (Database/SCADA).
3. Persistence & Beaconing
We look for signs of a breach that has already happened. We identify encrypted communication to unknown external servers and “Living off the Land” techniques that bypass standard firewalls.
The Deliverable:
The UnRavl Evidence Report
At the conclusion of the 72-hour hunt, our Lead Threat Hunter delivers the Evidence Report. This is a direct truth briefing that translates complex technical data into executive-level business risk.
The Findings Brief
A clear summary of the most critical exposure points.
The Movie Plot Scenarios
Realistic pathways an attacker would take to disrupt your specific business operations.
The Migration Roadmap
A prioritized 30-60-90 day plan to secure your environment.
Operational Impact: Zero
The PulseCheck is designed to be zero-friction.
- Passive Collection: We do not install software or modify your existing network
- Low-lift for IT: Your team provides a power outlet and a SPAN port. We handle the rest.
- Rapid execution: Deployment to reporting is completed in roughly 7 days
PulseCheck+™
Continuous Threat Hunting
Moving from Point-in-Time Audits to Persistent Intelligence
Most threats don’t wait for your annual audit. PulseCheck+™ embeds UnRavl’s elite threat-hunting intelligence directly into your infrastructure, providing 24/7/365 visibility into your most critical assets.
Why Continuous Monitoring Matters for Critical Infrastructure
Cybersecurity for critical infrastructure is no longer a “set-it-and-forget-it” task. New vulnerabilities emerge daily, and legacy systems often remain “blind” to modern attacks. PulseCheck+™ closes the gap between standard perimeter defense and active forensic hunting.
The Four Pillars of Continuous Protection
1. Automated Monthly Threat Hunting
We don’t just watch logs; we hunt. Our team conducts recurring forensic deep-dives into your network traffic using our proprietary Sovereign Pipeline. We identify lateral movement, unauthorized credential usage, and “Living off the Land” techniques that bypass traditional firewalls.
2. The Sovereign Shield & Setry
We deploy a hardware-backed security layer—the Sovereign Shield—to your perimeter. This zero-touch infrastructure creates an encrypted, private corridor for data analysis, ensuring your forensic evidence is stored in our air-gapped Sovereign Vault, making it impregnable to deletion or tampering.
3. Advanced Asset Intelligence
You cannot protect what you cannot see. PulseCheck+ provides continuous monitoring of your OT and IT assets. We map every PLC, server, and workstation, identifying “Ghost Assets” and virtually patching legacy systems that can no longer receive official security updates.
4. External Intel & OSINT Monitoring
We extend our eyes beyond your network. PulseCheck+™ includes continuous monitoring of the Dark Web and public-facing assets (OSINT) to identify leaked credentials or misconfigured ports before they can be exploited by external actors.
The Monthly Intelligence Brief
Every month, you sit down with our Lead Threat Hunters and vCISO for a strategic briefing. We move beyond raw data to give you the direct truth on your risk profile, providing a clear roadmap for mitigation and Board-level reporting.

Frequently Asked Questions
Will PulseCheck disrupt our operations?
Absolutely not. Our passive monitoring approach never touches your production equipment. We can deploy during normal operations with zero downtime risk.
How is this different from a penetration test?
Pentests show theoretical vulnerabilities. PulseCheck hunts for actual threats already in your environment. Plus, pentests often require taking systems offline–we never do.
What if we don't have internal IT expertise?
That’s exactly why PulseCheck exists. Our reports are designed to be understood by operations teams, not just IT specialists. We translate technical findings into operational language.
What happens after the assessment?
You get a prioritized roadmap of fixes. We can help implement them, or your team/existing vendors can. We provide 30 days of support for questions.
How often should we do this?
Most critical infrastructure operators do annual assessments. Some do quarterly for high-risk environments. We recommend at least annually, plus after any major system changes.
Will this satisfy our compliance requirements?
PulseCheck findings support AWIA, NERC CIP, EPA, and other compliance frameworks. We provide documentation formatted for auditors and regulators.
