Critical Start Leadership

New thinking to stay ahead of 21st century threats.

The Critical Start Leadership team has a collective experience that surpasses the first cyberattack ever recorded. But it’s not our history that matters. What’s essential is how we focus that experience and knowledge through a lens of innovation to prepare for the threats of the future. It’s how an entirely unique approach to MDR was created to ensure that no alerts or breaches are missed.
