AppCanary – Keep vulnerable software off your servers

In plain words

AppCanary monitors servers to prevent the use of vulnerable software. The tool is designed for software developers and system administrators who need to ensure their deployed applications stay secure. It scans for known vulnerabilities and alerts users so they can take action before vulnerable dependencies cause problems. The company has since joined GitHub to expand its impact on software development security practices.

From when we cofounded Rubysec , to building (the now defunct) Gemcanary , to starting Appcanary , our goal from the beginning was to improve the world’s security by preventing the use of vulnerable software. At the time, this required placing a bet on building a certain kind of business, and for a variety of reasons that bet didn’t work out. However, this doesn’t mean that we’re giving up on the mission! Today, we’re excited to announce that we’re going to be able to build tools that impact…from appcanary.com

  Keep – GitHub Actions for your monitoring tools2023 · github.com · ▲181

  Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…

  Socket – Secure your JavaScript supply chain2022 · socket.dev · ▲133

  Excited to share the project I've been working on for the past 7 months! We've seen nearly weekly attacks against the open source software supply chain. I saw the seeds of this trend start in the mid 2015s as an open source maintainer and I've watched it only get worse over the years. I finally decided to try to solve this problem. Socket is taking an entirely new approach to one of the hardest problems in security in a stagnant part of the industry that has historically been obsessed with just reporting on known vulnerabilities. Unlike other scanning tools, Socket actually analyzes the…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
