Infosec.exchange is a Mastodon-based social media instance focused on information security topics. If you're asking whether it's safe to trust, the short answer is: it depends on what you're planning to do here.
Let's start with what looks good. The site runs on modern infrastructure with fast load times, solid email authentication that prevents spoofing, and multiple layers of browser security. It hasn't been flagged by Google's safe browsing tools, and it has been online for a few years now. For casual reading and light participation, those are reassuring signals.
But here's the catch: infosec.exchange doesn't tell you who operates it. There's no company name, no legal entity disclosure, and no obvious contact information on the homepage. For a social platform where you're expected to create an account — and where your posts, followers, and possibly personal details live — this is a meaningful gap. Most legitimate social platforms make it easy to find out who's behind them and how to reach support.
That doesn't mean infosec.exchange is a scam. It likely isn't. But it does mean you're trusting an anonymous operator with your data. If you create an account, use a strong, unique password and don't share sensitive information. For now, the site earns a "use caution" rating: the technical bones are good, but the human element is missing.
