Practical guides to fixing what matters.
The EdgeProtect blog is a set of free, practical guides for IT and security teams. They explain how to rank flaws by real risk instead of raw severity, how exploit likelihood scoring works, how to find what you have exposed online and how to explain cyber risk to a board.
Every guide, by topic.
Pick a topic, or read them all. Every guide is free to read, with no sign-up.
The week in threats, every Friday.
Each Friday we round up the flaws newly confirmed as exploited, the biggest jumps in exploit likelihood, what attackers went after and the week's malicious packages.

We do the ranking for you, continuously.
EdgeProtect gives every published flaw a risk score from 0 to 100, built from evidence it is being exploited, how severe it is, how widely exposed it is and threat activity. You see only the flaws in software you use, riskiest first.
- Evidence of attacks counts mostA flaw being exploited outranks one that only sounds worse on paper.
- Confirmed exploited means act nowAnything confirmed exploited is marked Emergency patch, whatever its score.
- Over 400,000 CVEsrescored as the evidence changes, so the order shifts when the threat does.
