    Good enough…isn’t.

    Every alert is important because every alert tells a story. And that story can stop a threat. So, stop settling for so-called good security that just prioritizes alerts and allows real intruders to fall through the cracks.

    Detect every threat. Resolve every alert. Stop breaches.
