Built for OT security engineers, SOC teams, and MSSPs who can't afford to miss a critical advisory. Set up a watchlist by vendor, product, or sector. Filter by CVSS severity. Track your assets and see exactly which ones are at risk. No more manually checking CISA every morning. Plans from £29/month with a 14-day free trial.
Hey Product Hunt! 👋
I'm Nicki, a commissioning engineer. A while back I started noticing something that bothered me. The vendors whose systems I work with every day (Kongsberg, Siemens, Rockwell) regularly publish security advisories for their kit. Some serious stuff — critical-severity bugs, a few already actively exploited. But nobody in the marine and defence world seemed to know.
The problem is CISA publishes hundreds of advisories a year, buried on their website. No email alerts, no way to filter to just the gear you actually use.
So I built OTWarden. Set up a watchlist by vendor, product or sector and we monitor CISA, Siemens ProductCERT, Rockwell, BSI and more. When something relevant drops you get an email within 2 hours.
Happy to answer questions about ICS/OT security or how OTWarden works. What do you use currently to track vendor advisories?
