About

I am a Cybersecurity Engineer with 2+ years of experience specializing in Identity & Access Management (IAM), enterprise security operations, and Public Key Infrastructure (PKI). My focus is ensuring robust identity governance, securing privileged access, and maintaining seamless enterprise uptime. Currently at Cognizant, I manage the infrastructure lifecycle of 1,500+ SSL/TLS certificates using Sectigo and DigiCert, maintaining a near-zero downtime record (only 1 outage in 2 years). Core Expertise: Okta SSO, SAML 2.0, SCIM, User Provisioning, RBAC, Multi-Factor Authentication (MFA). Certificate Management: PKI, CSR generation, validation, renewal, and revocation across DigiCert and Sectigo. Privileged Access: CyberArk Vault Administration, Safe Management, CPM password rotation, and PSM session monitoring. Open to PKI Engineer, IAM Engineer, and Cybersecurity Analyst roles (India or Remote). Let's connect!
