4 Auth Companies With SCIM Support in 2026
If you're building a B2B SaaS product, chances are your enterprise prospects are already asking about SCIM provisioning. It's one of those checklist items that shows up late in a sales cycle and can quietly kill deals. "Does your platform support automated provisioning?" If the answer isn't yes, IT teams at larger companies will move on.
The good news is you don't have to build SCIM from scratch. There are auth providers that handle the heavy lifting for you, so you can add compliant user provisioning to your product without months of custom implementation work.
We looked at four auth companies that can help you ship SCIM support in 2026: Frontegg, Descope, PropelAuth, and WorkOS.
What is SCIM provisioning?
SCIM (System for Cross-domain Identity Management) is an open standard that lets an identity provider like Okta, Microsoft Entra ID, or Google Workspace automatically manage users in your product. When a company hires someone, that person gets provisioned into your app. When they leave, they get deprovisioned. No manual work, no stale accounts sitting around with active access.
In practice, the main reason enterprise IT teams ask for SCIM isn't to keep profile data in sync. It's deprovisioning. When an employee leaves a company, IT needs to cut their access to every tool immediately. Without SCIM, that means someone manually going through a list of apps and removing the user from each one. With SCIM, it happens automatically the moment the user is deactivated in Okta, Entra ID, or whichever identity provider the company uses.
From a development perspective, supporting SCIM means exposing a set of REST API endpoints that follow the SCIM 2.0 spec. Your app becomes a "service provider" that receives provisioning requests from your customers' identity providers. Building that from scratch is doable, but it's tedious. Different IdPs implement the spec slightly differently, and edge cases add up fast. That's why most teams reach for a provider that abstracts it away.
WorkOS
WorkOS is a well-known name for enterprise features, and SCIM provisioning is part of their offering. Their Directory Sync product normalizes user provisioning from various SCIM and HRIS systems, sending real-time webhooks when users are created, updated, or deactivated in a customer's directory. It supports major identity providers including Okta, Microsoft Entra ID, and Google Workspace.
The documentation is solid, but the pricing is where things get complicated.
Directory Sync is priced at $125 per active connection per month, and SSO is priced the same way. If you're supporting 20 or 30 enterprise customers with both, the bill adds up quickly. For most early-stage teams, that per-connection model ends up being more expensive than it initially appears, and by the time you're at scale it can be a significant line item. There are providers on this list that offer more predictable costs as you grow.
PropelAuth
PropelAuth is the only provider on this list built exclusively for B2B products, and that focus shows throughout. Rather than being a general auth platform that happens to support SCIM provisioning, every part of it, from organizations to roles to user management to automated provisioning, is designed around the assumption that your customers are companies, not individuals. SAML, OIDC, and SCIM are deeply integrated into the organization model, and your customers can onboard themselves with self-service setup.
What really sets PropelAuth apart is flexibility in how you adopt it. For teams that don't want to rip out their existing auth stack, their "bring your own auth" (BYO) option is genuinely useful. PropelAuth BYO is a self-hosted sidecar, written in Rust, that lets you add only the auth pieces you need without replacing what already works. Run it in your cloud, keep full control of your data, and adopt features one at a time. For SCIM specifically, you stand up a single catch-all route and forward requests to the sidecar, which parses the request and tells you what action is required, like linking a user on first-time provisioning or disabling them on deprovision, so you keep control of your data model without having to build the whole spec yourself.
For a team that's already mid-product and just needs to close the SCIM gap without a full platform migration, that's a much more practical path than starting over.
Frontegg
Frontegg bundles SSO, SCIM, RBAC, and a self-service admin portal into a single B2B SaaS platform, which makes it a solid option if you want enterprise readiness without stitching together multiple tools. The admin portal is a genuine selling point, since your customers' IT teams can configure their own SSO and SCIM connections without filing a support ticket with you.
There are two caveats worth knowing upfront. First, SCIM provisioning is only available on Frontegg's enterprise tier so factor that into your pricing model early. Second, identity logic is tightly coupled to Frontegg's provided UI components, so teams building API-first products or custom authorization models can find themselves working around the platform rather than extending it. It's a good fit if you're moving fast and want a complete, opinionated solution. Less so if your auth requirements are non-standard.
Descope
Descope takes a visual, workflow-driven approach to identity that sets it apart from more code-heavy alternatives. Their platform unifies SCIM provisioning, SSO, authentication, and authorization into a single developer-friendly platform, with tenant-aware provisioning that automates user creation, updates, and deprovisioning per organization. If your team prefers building auth flows through a drag-and-drop interface rather than writing configuration from scratch, Descope is one of the few providers that makes that genuinely viable at a production level.
The main thing to watch is pricing. SCIM is gated to the Growth tier at $799/month, so it's not the most accessible option for teams at an early stage. If you're comfortable with that entry point and want a low-code approach to the whole identity stack, it's worth a look.
Which SCIM provider should you choose?
It depends on where you are and what you're building.
For most B2B SaaS teams, PropelAuth is worth serious consideration. It's the only provider on this list built exclusively for B2B, which means the assumptions baked into the platform actually match how your product works. And the BYO sidecar option is a genuine differentiator. If you already have auth in place, you can add SCIM without touching the rest of your stack or handling webhooks.
Frontegg is a solid choice if you want a single platform that handles auth, provisioning, and the admin portal layer in one go, and you're comfortable working within its opinions about how that should look. Descope suits teams that want to build and iterate on identity flows visually, without writing everything from scratch. WorkOS is an option, though as covered above, the pricing model is something to think carefully about before committing.
If SCIM provisioning is the specific problem you're trying to solve and you want a platform that was built around B2B from day one rather than adapted for it, PropelAuth is the place to start.
