Not Every Insider Is an Attacker

Most insider incidents are not malicious, and a program built only to catch bad actors misses the far more common careless one

Insider threat programs are usually built around a villain: the disgruntled employee, the planted operative, the person stealing on the way out. That framing is vivid, and it quietly narrows the aperture. A large share of insider incidents involve no malice at all.

They involve a rushed employee who shares a folder too broadly, emails a sensitive file to a personal account to finish work at home, or misconfigures access trying to help a teammate. There is no intent to harm, and there is real exposure all the same. Controls tuned to hunt for bad actors often wave the careless ones straight through.

Harm Without Intent

A malicious insider works to stay hidden. A negligent one has no reason to, which is precisely why detection built on suspicion misses them. The behavior looks like helpfulness and productivity, someone trying to get their job done. The damage lands regardless of the motive behind it.

Baseline Behavior, Not Motive

PeopleBase profiles each person's own norm and flags risky data movement against it regardless of motive, so the folder shared far too broadly or the file sent to a personal account surfaces whether a thief or a helpful employee did it. The behavior is visible before anyone has to guess at intent.

You cannot screen for carelessness the way you screen for malice. You can watch for the behavior that gives either one away.
