Frenos: The OT Security Simulator

A $5.7M startup betting everything on simulated attacks for critical infrastructure

While most cybersecurity startups chase headlines with flashy AI promises, Frenos is quietly building a simulation engine for the world's most dangerous networks. They're not just finding vulnerabilities—they're stress-testing the lights-out defenses of power plants and water facilities against real-world adversaries.

"Frenos isn't selling tools—they're selling confidence that your critical infrastructure won't collapse when Volt Typhoon shows up."

The OT Security Gap

Traditional IT security tools fail spectacularly in operational technology environments. You can't just 'patch' a nuclear power plant's SCADA system. Frenos recognized this early: OT security requires simulated penetration testing, not vulnerability scanners. Their 33-person team is laser-focused on this niche, ignoring the broader cybersecurity noise.

Traffic Tells a Story

Here's what's fascinating: 74% of their traffic is direct. That's not SEO magic or ad spend—it's a sign of strong word-of-mouth in a closed industry. When OT security professionals search 'frenos' (2,090 monthly searches), they're not discovering a new tool; they're returning to a solution that works. The 10% organic traffic suggests they're still early in capturing the broader market.

Their keyword strategy reveals a sophisticated understanding of their buyer. Ranking for 'vendro ai' (9,860 searches) and 'robert m lee' (690 searches) shows they're targeting technical buyers who know the OT security landscape. This isn't a product for CISOs who want dashboard eye candy—it's for engineers who understand NERC CIP standards and Volt Typhoon tactics.

  • Simulated OT penetration testing: They don't just scan—they emulate adversary behavior in controlled environments
  • AI-driven prioritization: Critical infrastructure can't fix everything; Frenos tells you what matters now
  • Real-time adversary assessments: Continuous testing, not annual audits
  • Industry-specific focus: They ignore general IT security to dominate OT

The $4.88M Bet on Simulation

Frenos is betting that the future of OT security isn't about finding vulnerabilities—it's about proving you can stop attacks before they happen. With $4.88M in funding and $5.7M in revenue, they're not just surviving; they're building the standard for how critical infrastructure defends itself.
