Dedicated to eliminating data breaches forever.
Everyday, data is stolen and held for ransom to devastating effect. The same mountain of IP and PII that makes business possible also threatens to damage it beyond repair. It’s clear that traditional data security has become outmatched.
Calamu was founded by cybersecurity experts to solve this worsening problem. Years of R&D led to a breakthrough, a next-gen resilience technology so superior that ransomware becomes obsolete. Even if an attacker gets past your perimeter, with Calamu they get nothing of value–and your data remains safe and accessible, with zero downtime.
