Try Pipedrive →Single sign-on stops being a nice-to-have the moment your CRM holds real customer data and your headcount crosses the point where you can't remember who has a login. IT and security teams want one identity provider — Okta, Azure AD / Entra ID, Google Workspace — to be the single front door: one place to enforce MFA, one place to cut access when someone leaves, one audit trail. Without SAML, offboarding means someone manually remembering to disable a CRM seat, and "we deprovision within 24 hours" turns into a finding on your next SOC 2 or ISO 27001 report. SCIM takes it further: instead of admins creating and deleting CRM users by hand, the IdP pushes provisioning and, critically, deprovisioning automatically — a leaver's access dies the instant HR flips their status.
The catch is the "SSO tax." Almost every CRM gates SAML behind its top pricing tier, so the feature your security team considers table stakes is bundled with a per-seat price built for enterprises. You rarely buy SSO on its own; you buy the Enterprise plan and SSO comes along for the ride. That makes "which tier unlocks SAML" the real buying question, because the answer can triple your per-seat cost.
SAML 2.0 vs OIDC. Most CRMs implement enterprise SSO with SAML 2.0 — the XML-based standard IdPs like Okta, Entra ID, and Ping speak natively. Some newer platforms also support OpenID Connect (OIDC), the OAuth 2.0-based protocol that's lighter and more API-friendly. For a CRM, SAML is the safe assumption; confirm OIDC only if your IdP standardizes on it. Either way, "Sign in with Google" social login is not the same as SAML SSO — social login is a convenience feature, not a security control, and it won't satisfy an auditor.
SCIM auto-provisioning and deprovisioning. SAML handles authentication (who can log in); SCIM handles lifecycle (who has an account at all). Without SCIM, an admin still creates and deletes CRM users manually. With it, the IdP pushes new hires into the CRM with the right role and — the part security actually cares about — revokes access automatically when someone is offboarded. If instant deprovisioning is a compliance requirement, SCIM is non-negotiable, and it's a meaningfully smaller club than SAML: Salesforce and Dynamics do it well, HubSpot and Attio support it on Enterprise, Zoho and Pipedrive are thinner here.
Enforced vs optional SSO. Turning SAML on isn't the same as requiring it. Optional SSO leaves the native email-and-password login live in parallel, so a user can bypass your IdP (and your MFA policy) entirely. Enforced SSO disables password login and forces everyone through the IdP — that's what closes the loophole and what auditors look for. Check that your CRM lets you enforce, not just enable, SSO before you consider the control real.
JIT provisioning, sessions, and MFA. Just-in-time provisioning creates a user record on their first SSO login instead of pre-staging accounts — convenient, but it's not deprovisioning, so pair it with SCIM if leavers must lose access automatically. Session lifetime and re-authentication are usually inherited from the IdP, which is the point: enforce MFA, conditional access, and session timeouts once at the identity layer and every SAML-connected app obeys, CRM included.
Start with your identity provider and your compliance clock. If you already run Microsoft 365, Dynamics 365 through Entra ID is the least friction you'll find. If you're standardized on Okta or Google and want the deepest provisioning story, Salesforce is the safe enterprise answer. If the SSO tax is the problem — you need enforced SAML but can't justify a $150/seat Enterprise jump — Zoho CRM and Attio are the value plays, with Attio the more modern build and Zoho the cheapest path to real SAML.
Then pressure-test three things before you sign: can you enforce SSO (not just enable it), does SCIM handle automatic deprovisioning, and which exact tier unlocks both. The gap between "supports SSO" on a marketing page and "enforced SAML plus SCIM deprovisioning on the plan we can afford" is where most CRM security evaluations quietly go wrong.
