What Intruder is best at, for us, is the daily cadence combined with rapid response to newly announced CVEs. We get a scan every day as a matter of course, and rather than waiting for the next scheduled run when a new CVE is announced, Intruder kicks off an immediate scan against our systems. That gives us confidence we're not sitting exposed to a known vulnerability for hours or days while waiting on a routine check. Between the daily baseline and the on-demand emergency scans, it works well as both a retrospective health check ("are things still okay") and a proactive early-warning system when something new hits the wild.

Intruder does the core job well: continuous vulnerability scanning across both infrastructure and web apps from a single pane, with attack-surface monitoring that actually flags new exposures instead of just re-reporting the same noise. Setting up authenticated DAST was genuinely painless — the session-cookie approach for authenticated app scanning worked as documented and got us scanning behind login without a lot of trial and error. Findings are prioritized sensibly, so we spend time on what's exploitable rather than triaging a wall of low-severity items. Rolling it out across a multi-project cloud environment was clean, and the reporting is presentable enough to hand to non-security stakeholders and auditors with minimal reformatting.

It is simple to use, and staff are proactive and helpful.
