Preemptive is not a marketing word. It is the operating model.

Preisys was founded by Marcus Rivera in 2012, after a decade of federal and commercial incident response work. The pattern was always the same: an unpatched edge device, a reused administrator credential, a backup nobody had ever restored. The intrusions were rarely sophisticated. They were simply unanswered.

Rather than build another break-fix shop, Preisys was designed as a preemptive practice. Offensive security operators sit on the same floor as the service desk. When our red team finds a technique that works against a client, the managed services team hardens every other client against it that week.

Today Preisys protects more than 240 organizations across healthcare, professional services, manufacturing, and public sector — from twelve-person specialty firms to multi-site enterprises with regulated workloads.
