Free Security Tools & Resources
A growing collection of free, open‑source security tools I’ve built to give you clear visibility into what matters: what’s been patched, what’s being exploited, and what’s about to fall out of support. No accounts, no tracking, no marketing, just practical security data you can use every day.
These tools exist for one reason: most organisations don’t need more products, they need better awareness. Each dashboard is built to answer a specific question that improves security posture immediately.
Patch Tuesday Tracker
What’s been patched this month?
The Patch Tuesday Tracker collects security patch data across nine major platforms and updates automatically every day. It gives you a single place to see:
- all Patch Tuesday releases
- severity levels
- vendor advisories
- links to official documentation
- covers Windows, Apple, Android, Ubuntu, Red Hat, Debian, ChromeOS, Palo Alto Networks, and Cisco IOS/IOS XE.
If you only check one patching source each month, make it this one.

KEV Tracker (Known Exploited Vulnerabilities)
What’s being actively exploited right now?
CISA’s KEV catalog lists vulnerabilities confirmed to be under active attack in the wild. The KEV Tracker monitors that feed daily and highlights:
- newly added exploited vulnerabilities
- ransomware‑linked CVEs (flagged in red)
- remediation deadlines
- a full historical archive
When a vulnerability lands in KEV, it becomes a priority. This dashboard shows you exactly which ones matter today.
EOL Tracker (End‑of‑Life & End‑of‑Support)What’s about to stop being protected at all?
Software quietly ages out of support, and when it does, the vendor stops patching it. The EOL Tracker monitors end‑of‑life dates for 20 major products, Windows, macOS, iOS, Android, Ubuntu, Debian, Red Hat, Cisco IOS XE, PAN‑OS, VMware ESXi, Office, SQL Server, Python, PHP, Node.js and more.
It shows you:
- what’s reaching end of life within 90 days
- what recently went end of life
- full lifecycle tables for hundreds of versions
If unsupported software is still running in your environment, this dashboard will tell you.
Why These Tools Exist
Security isn’t about buying more products, it’s about knowing where your risks actually are. These dashboards give you the three signals every organisation should track:
- What’s been patched → Patch Tuesday Tracker
- What’s being exploited → KEV Tracker
- What’s expired → EOL Tracker
Patch what’s released. Prioritise what’s exploited. Replace what’s expired.
That’s patch management in one sentence and now there’s a free tool for each part.
