Your OT Security Team Is Overwhelmed And Still Not Sure They're Secure
Every OT security team faces the same crushing reality: Thousands of vulnerabilities across tens or hundreds of sites, but no way to know which ones actually matter. You're drowning in CVE alerts while real threats slip through the gaps. Your board wants proof of security improvements, but you can't measure what you can't test. When a new APT targets your industry, you have no idea if your defenses would hold.
The result? Your team works harder than ever but still operates on assumptions instead of intelligence.
Risk Benchmarking Challenge
No way to measure security improvements across sites or prove ROI to leadership
Vulnerability Overload
10,000+ CVEs flagged, but which 10 could actually shut down production?
Threat Uncertainty
When Volt Typhoon or BlackEnergy targets your sector, will your specific defenses hold?
Without continuous assessment, you're making million-dollar security decisions based on outdated reports and best guesses. Frenos changes that — giving you the intelligence to prioritize, defend, and validate your OT security with confidence.
