I’ve been putting together some security awareness materials for a small team, and I kept running into glossaries that were either way too basic (just “virus” and “firewall”) or buried under vendor product plugs.

After way too much searching, I stumbled on this cybersecurity glossary page that actually explains terms in plain language. The entry for XDR stood out to me because they don’t just throw a definition at you – they connect it to something practical like how user reporting of phishing feeds into the tool. That’s the kind of real world link I rarely see in these lists.

Figured I’d share in case anyone else needs a straightforward reference without the usual noise. Bookmark material for me.

Has anyone else found a go to glossary they actually use day to day?
