You know you should be tracking ICS vulnerabilities. You don't have time.

CISA publishes new OT security advisories every week. Each one could affect your plant floor, your SCADA system, or your building management controllers. Missing a critical vulnerability means risking unplanned downtime — or worse.

  • Manually checking CISA's website every Tuesday
  • Subscribing to 15 different vendor security mailing lists
  • Wading through advisories that don't affect your equipment
  • Enterprise OT security platforms that cost £50k+ per year

Questions

Where does the vulnerability data come from?

All data comes directly from CISA (the US Cybersecurity & Infrastructure Security Agency), the authoritative source for ICS security advisories worldwide. We parse their machine-readable CSAF 2.0 feeds and cross-reference with the National Vulnerability Database.

How fast will I receive alerts?

We check for new advisories every 2 hours. Essential plan subscribers receive alerts within 2 hours of publication; Professional and Team subscribers within 1 hour. For critical zero-day advisories, we aim for under 30 minutes.

I'm not in the US. Are the alerts still relevant?

Absolutely. CISA ICS advisories cover vulnerabilities in equipment sold and deployed worldwide — Siemens (Germany), Schneider Electric (France), ABB (Switzerland), Yokogawa (Japan). If you use industrial control systems, these advisories affect you regardless of location.

What's the difference between this and the free CISA email list?

CISA's email list sends you every advisory — hundreds per year across all vendors. We filter to only your equipment, add severity scoring, plain-English summaries, and specific remediation steps. No more sorting through irrelevant alerts.

Can I monitor specific products, not just vendors?

Yes. You can watch at the vendor level (e.g. "all Siemens advisories"), the product level (e.g. "SIMATIC S7-1500 only"), or the sector level (e.g. "Water and Wastewater"). Mix and match across your watchlist.

Do I need to install any software?

No. It's an email-based service. You sign up, choose your watchlist, and alerts arrive in your inbox. There's also a web dashboard to view alert history, but the core product is the email alerts.
