What we do
We deliver internal and GAP audits for ISO 27001 and ISO 9001, readiness reviews, annual audit planning, and practical assessments of controls, documentation, risk, and process effectiveness.
What makes us different
We combine ISO 19011 audit discipline with real-world experience in software engineering, cloud infrastructure, IAM, secure integrations, and production operations. That helps us assess not only documentation, but how controls work in practice.
What we can state publicly
Publicly stated credentials include ISO 19011 audit methodology, ISO/IEC 27001 and ISO 9001 lead auditor training, and CCSK cloud-security knowledge.
How we work
We work independently, confidentially, and evidence-first. The goal is clear criteria, traceable evidence, practical recommendations, and minimal disruption to the client’s operations.
