**Direct answer:** Learn **Entra ID** first (every Microsoft estate has it). Add **Okta** if the JD is workforce SSO. Add **SailPoint** when the JD says IGA, access certifications, or SoD. They are not substitutes. Entra/Okta authenticate; SailPoint governs entitlements across many apps.

Career ROI in Chennai

TCS/Cognizant/Wipro IAM tickets are often Entra + SailPoint. Product companies and some GCCs are Okta-heavy. A candidate who can only recite “what is SSO” loses to someone who has federated one app and run one certification campaign.
