Crowdcruit▲44Hey HN, I'm an offensive security engineer (OSCE3) who's been frustrated for years with how broken cybersecurity hiring is.

So we have bootstrapped Crowdcruit: a hiring platform purpose-built for cybersecurity, combining verified technical achievements (CVEs, bug bounties, HTB/THM scores, certifications) with a smart matching system. Key Features: + Smart Matching: Candidates are matched to roles based on real-world skills — not just keywords. + Bug Bounty & CVE…

IPDetective collects data from about 60+ different sources such as official cloud provider endpoints and public VPN/Proxy/Tor/Bot net lists. Then aggregates this data into a fast and easy to use API that can be integrated into applications or scripts easily. IPDetective started as a hobby project for my other hobby projects :) and I decided to wrap a simple website around and offer it as a service. Let me know what your thoughts, if you find value in this service or if you have any feature requests.

Like many of you, I find Google results to be full of SEO spam and have resorted to adding "site:reddit.com" or "site:news.ycombinator.com" to all my queries (since 2015!). Otherwise, it's really hard to figure out "what does a genuine, real life human think about this thing?". But limiting my results to just Reddit isn't ideal because so much great content exists elsewhere. Lots of great information…
