Turn the odds in your favor

The move to hybrid work and the cloud have scattered your IT infrastructure, creating cracks in your security programs. Attack surface management (ASM) actively discovers, learns and responds to your unknown risks in all connected systems and exposed services.

Fight back with Active Attack Surface Management.

Resolve unknown exposures with automation

Legacy vulnerability scanners scan infrequently. Security ratings and periodic pentesting are fine for your known assets. But what about the 30% or more assets that you’re not monitoring?

ACTIVE DISCOVERYACTIVE LEARNINGACTIVE RESPONSE

Active discovery

Automatically, continuously scan the entire internet. Actively discover and index your unknown risks in all connected systems and exposed services.

Active learning

Use supervised machine-learning models to continuously map your attack surface and prioritize remediation efforts. Reduce MTTD and MTTR without additional analysts.

Active response

Immediately reduce your attack surface risks with built-in automated playbooks instead of merely raising IT tickets.

Automatically find and fix your risks

IT tickets don’t reduce your risk, but automation does. Fix your unknown exposures before attackers find them.
