You know you should be tracking ICS vulnerabilities. You don't have time.
CISA, Siemens, Rockwell, BSI and other security authorities publish new OT advisories every week. Each one could affect your plant floor, your SCADA system, or your building management controllers.
- ✕ 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

Tell Us Your Equipment
Select the vendors, products, and industrial sectors you care about. Siemens PLCs? Schneider SCADA? Rockwell controllers? Pick as many as you need.
We Check Multiple Sources Around the Clock
We pull from six authoritative sources: CISA ICS-CERT, BSI CERT-Bund (EU), Siemens ProductCERT, Rockwell Automation, the CISA KEV catalog, and NIST NVD. When a new advisory is published, we parse it, score it, and check it against your watchlist within 2 hours.
Get Actionable Alerts
If it affects your equipment, you get a clear email: what's vulnerable, how severe it is, and exactly what to do about it. No jargon. No noise.
Six authoritative sources. One inbox.
We aggregate from every major ICS/OT security authority — no important advisory slips through.
More than just email alerts
OTWarden goes beyond forwarding CISA advisories. It's a full vulnerability management workflow built for OT teams.
Asset Inventory Matching
Log your OT devices once. Every alert detail page then shows you exactly which of your assets are affected — no manual cross-referencing.
Compliance Deadline Tracker
Set remediation deadlines per alert. RAG-status badges (red/amber/green) surface overdue items at a glance on your alert list and dashboard.
Shodan Exposure Indicator
Each alert shows an estimated count of internet-exposed devices matching the affected product, so you can prioritise the most critical issues first.
Peer Benchmarking
See how your patch rate compares to the platform average — an honest measure of your OT security posture that you can report upwards.
Agency Multi-Client Management
Manage up to 50 client accounts under one Agency subscription. Switch context with one click — each client gets their own watchlist, alerts, and assets.
Webhook & API Integration
Push advisory matches to PagerDuty, Opsgenie, Slack, Teams, Zapier, or any HTTPS endpoint. Pull your data via REST API for custom workflows.
See what you'll receive
No noise. Just the advisories that affect your equipment.
Delivered within 2 hours of CISA publishing. Matched only to vendors on your watchlist.

Questions
Where does the vulnerability data come from?
We pull from six authoritative sources: CISA ICS-CERT (CSAF 2.0), BSI CERT-Bund (Germany's equivalent — also CSAF 2.0), the Siemens ProductCERT feed, Rockwell Automation's security bulletin feed, the CISA Known Exploited Vulnerabilities (KEV) catalog, and NIST NVD for additional CVE enrichment. Vendor-native feeds (Siemens, Rockwell) are available on Professional and Team plans.
How fast will I receive alerts?
We check for new advisories every 2 hours. Essential plan subscribers receive alerts within 2 hours; Professional and Team subscribers within 1 hour.
I'm not in the US. Are the alerts still relevant?
Absolutely. CISA ICS advisories cover equipment sold worldwide — Siemens (Germany), Schneider Electric (France), ABB (Switzerland), Yokogawa (Japan).
What's different from the free CISA email list?
CISA sends you every advisory regardless of whether it affects your equipment. OTWarden filters to your exact vendors and products, adds CVSS severity scoring, flags actively exploited CVEs (KEV), pulls in Siemens and Rockwell advisories before CISA republishes them, enriches every CVE with NIST NVD data, and includes EU advisories from BSI CERT-Bund that CISA never covers. Plus compliance tracking, asset matching, and Shodan exposure counts.
Can I monitor specific products, not just vendors?
Yes. Watch at vendor level, product level, or sector level. Mix and match across your watchlist.
Do I need to install any software?
No. Sign up, choose your watchlist, and alerts arrive in your inbox. You also get a web dashboard to view alert history.
Are there any free tools I can use without signing up?
Yes. Three tools are available to everyone with no account required: the CVE Lookup (search any CVE and see which ICS advisories reference it), the Sector Risk Dashboard (advisory activity broken down by industry), and This Week in ICS (the most recent advisories across all sources). All free, no signup needed.
Can OTWarden support NERC CIP or IEC 62443 compliance?
Yes. Professional and Team subscribers receive a monthly PDF report documenting every advisory matched to their watchlist, including severity, CVEs, and remediation status. You can also set per-alert remediation deadlines and export a full audit trail. Suitable for NERC CIP, IEC 62443, and NIS2 evidence requirements.
Can I track which of my actual devices are affected?
Yes. On Professional and Team plans, you can build an asset inventory of your OT/ICS devices. When you open any alert, OTWarden automatically shows you which of your logged assets match the affected vendors — no manual cross-referencing needed.
