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! 💕

#IoTSecurity #Reachability

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:

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.

I kept getting a blank grey area showing at the top of my screen on #ios, and then I'd swipe up and it would disappear. This has been happening for years.

Today I decided to find out what it was.

It's a feature called #Reachability. If you operate your phone with one hand, and it has a screen which is too large for you to reach the icons at the top of the screen with your thumb, you can make it bring the top of the screen down within reach.

Just double tap the home button.
