About Octavian Mihail
I help companies find and fix security weaknesses before attackers do.
With hands-on experience in pentesting, cloud security, Microsoft 365 audits, and secure infrastructure design, I provide clear findings, real impact validation, and actionable remediation plans — tailored to your environment, not generic checklists.
