You will live inside the admin consoles of Okta, Zscaler, Google Workspace, and Microsoft 365, reconstruct how our environment and security tools are configured, challenge inherited assumptions and exceptions, identify exploitable attack paths, and personally architect, prototype, automate, and drive durable fixes into productionYou will combine an adversary’s mindset with disciplined defensive engineering.

Exhaustive audit and remediation of external sharing: link-sharing defaults and expiry, target audiences, shared drives and site-level overrides, guest and unmanaged-device access, sensitivity labels and Purview / Google DLP rules, Entra ID Conditional Access, th...
