How we do it

A True Compass

We can focus our considerable detection engineering expertise to guide you on optimizing your log data sources for effective threat detection. The right configuration will maximize visibility.

Trust but Verify

Our Trusted Behavior Registry (TBR) automatically resolves what is known-good and can be safely resolved first–shifting focus to unknown alerts for triage and quick resolution.

A New Roadmap

We create playbooks on known-good alerts and put them into the TBR. If it’s not in a playbook, it’s an unknown, given to the SOC and analyzed.

100% Transparency

Our MOBILESOC app puts every action, full investigation details, and complete visibility across your security environment right at your fingertips.
