Just added Web Reachability API (at least that’s what I’m calling it) support to https://ip.small-web.org.
It’s for testing the reachability of your Small Web servers (using a domain or, more importantly, an IPv4/IPv6 address). I’m using it to implement Web Numbers¹ support in Auto Encrypt² and Kitten³.
Protocol:
• At http://<endpoint> return an empty HTTP 200 response that includes the following custom header: 'web-reachability-id': ‘<uuid>'
• Hit: https://ip.small-web.org/reach/<endpoint>/<uuid>/
• If you get a 200 response back, your endpoint is reachable. Anything else signals an error.
Enjoy! 💕

Our new datasheet breaks down how Finite State helps product security teams
🎯 Pinpoint the truly reachable vulns & focus remediation
🔄 Automatically resolve ones that aren’t
⏱️ Slash triage time & streamline VEX documentation

Not all vulnerabilities matter.
If it’s not reachable, it’s not a real threat.
Xygeni cuts through the noise with Reachability Analysis:
🔎 Focus only on vulnerabilities actually invoked by your code
🚫 Skip what’s never triggered
🚀 Native to your CI/CD pipeline
Smarter triage. Real risk. Less noise.

Endor Labs ❤️ #GitHub
Context switching is a productivity killer. Developers live on GitHub, so #AppSec should too.
Over the past year, we’ve been working closely with the GitHub team to help customers achieve end-to-end application security, without having to leave GitHub, with remarkable results.
With Endor Labs #Reachability -based #SCA now integrated into GHAS, teams can get best-in-class application security, all in one place.
More about this integration here:
https://github.blog/security/from-finding-to-fixing-github-advanced-security-integrates-endor-labs-sca/
The partnership between GitHub and Endor Labs enables application security engineers and developers to drastically reduce time spent on open source vulnerabilities, and gives them the tools to go from finding to fixing.
For development teams awash in #vulnerability reports, #reachability analysis can help tame the chaos and offer another path to prioritize exploitable issues🛡️🔐

Reachability Analysis (RA) is a stellar toolbox for safety analysis and safety verification in various contexts, but to name one is autonomous driving and navigation.
