ABOUT SIDNEY DIZON
Sr. Business Application Administrator with hands-on expertise in identity infrastructure, endpoint security, SaaS governance, and Zero Trust architecture. I serve as the primary technical owner of enterprise IAM (Okta, Azure AD/Entra ID), device compliance (Intune, Kandji, JAMF), and collaboration platform hardening across Microsoft 365, securing environments that support thousands of users.My day-to-day work spans designing and enforcing conditional access policies, maturing Zero Trust models, governing SaaS application ecosystems at scale, and automating identity lifecycle processes from onboarding through offboarding. I work cross-functionally with GRC, IT Operations, and Legal teams to implement controls that satisfy SOC 2 and ISO 27001 compliance requirements — translating risk into actionable, measurable security improvements.Previously, I led our ServiceNow-to-Zendesk platform transition as technical lead, contributing to ~$2.8M in annual savings while bringing administration and development in-house. My foundation is in cloud infrastructure (AWS, Azure), identity protocols (SAML, OIDC, OAuth), and scripting/automation (Python, Bash, PowerShell, Terraform), and I bring a security-first mindset to every integration, policy, and workflow I touch.Always happy to connect with others working in IAM, corporate security engineering, endpoint hardening, or Zero Trust strategy.
