OTWarden

ICS/OT vulnerability alerts before attackers exploit them

What it does

OTWarden monitors CISA, Siemens ProductCERT, Rockwell, and BSI advisories and emails you within 2 hours when a vulnerability affects your ICS/OT systems. 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.

    With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
