Simplify breach prevention
and keep your business thriving.

Say goodbye to complex managed detection and response and hello to simplicity.

We take a different approach to managed detection and response by simplifying your operations.

WHAT WE DO

Detect the Right Threats

We dive in deep to understand your security operations and requirements.

Provide Agility and Adaptability

We’re with you every step of the way to improve your security posture—even as your environment changes.

Respond with the Right Actions

With our seasoned security analysts and one-of-kind technology at your side, we’ll help you make accurate decisions on the right response to protect your security operations.

OUR SERVICES ARE DIFFERENT

99% reduction in alert volume.

Our Trusted Behavior Registry resolves all alerts. If a known false positive surfaces, we’ll resolve it rather than forwarding it on to your team.

100% transparency and visibility.

You’ll get full details on every alert, investigation and response action we take. We don’t hide anything.



1-hour or less guarantee.

We give you our word to satisfy service level agreements for Time to Detection (TTD) and Median Time to Resolution (MTTR) for every single alert.

Respond to alerts on the go.

With MOBILESOC®, a mobile app that gives you full access to alerts, tickets, reports and investigation details.
