Every engagement ends with a number.

30+ projects delivered at a 99.9% implementation success rate. Five of them below — what we built, and the number each one moved.

What clients say once it ships.

Two engagements, in the client's own words. One reached SOC 2 certification; the other turned GDPR into engineering work their teams could execute.

Zefroc took us from no formal security program to SOC 2 certification. They did the engineering work, not just the paperwork — our infrastructure is genuinely better for it.
Sarah Johnson
CTO, TechCorp Inc.
Their guidance through GDPR compliance was exceptional. They translated regulation into concrete engineering and process changes our teams could actually execute.
Michael Chen
Privacy Officer, Global Health Systems

Government

Secure, compliant modernization for public-sector workloads.

Manufacturing

Observability and uptime engineering for production systems.

Retail & E-commerce

Scalable, secure storefront infrastructure that survives peak.

Your stack could be the sixth case study.
