Head-to-head · updated 13 September 2026
DataShield vs Descope: who issues the agent's token, and who proves what it did?
Descope is good at the thing it says it's good at. Their Agent Identity Hub gives an AI agent a real OAuth ID. It guards your MCP server with OAuth 2.1 and per-tool scopes. It vaults the tokens it hands out. It gives you SDKs that work fast. Their Cross-App Access work on ID-JAG is standards leadership. Not just a launch post. Build SaaS? Need login plus agent auth? Buying Descope is a sensible call.
We sell a different layer. DataShield is a control plane for ruled data. We tokenize datasets at ingest. Agents query the tokens over MCP. Turning a token back is a gated, logged run. We re-check each checked call against the agent's live rights. We seal each choice into a chain. You can check it without trusting us. Most buyers who look at both end up running both. Below is the honest split, plus the rows Descope wins.
The short version
Pick DataShield when
- An examiner will one day ask for the March logs. They'll want to know they weren't edited. Our chain answers with math, not a policy PDF. Run the verifier.
- You need an agent's authority pulled mid-session. The very next tool call should fail, rather than waiting out a short-lived token.
- The data itself is the risk. PHI, card-adjacent records, subject data: tokenized at ingest. The agent never queries raw values. How that works.
- Your rules say the policy engine, the vault, and the evidence run on your own infrastructure, with your keys.
Pick Descope when
- You're building a SaaS product. You need customer login and agent auth from one platform. That's their home turf. They've been at it since 2022.
- You want to start free today. Free Forever is $0 for 7,500 MAUs. Sign-up is self-serve. Nobody makes you book a call.
- You need OAuth 2.1 MCP server protection, with dynamic client registration, RFC 8693 token exchange, and SDKs in your language. Their docs are better than ours.
- ReBAC fine-grained authorization with a local cache is the shape of your problem. They quote 0.3 to 0.7 ms per check, for agents doing hundreds of lookups per inference.
Bottom line: Descope decides whether an agent gets a token. DataShield decides what the agent may do with the data, and keeps proof. If your product is an app, start with them. If your exposure is ruled data and an audit, start here, and keep Descope for the login.

| What matters | DataShield | Descope | Edge |
|---|---|---|---|
| Audit evidence | SHA-256 hash chain with Ed25519-signed checkpoints that are themselves chained. Verification names the failure: tamper, insertion, delete, or cut-short. Try the checker. | An audit trail that ties each action back to the originating user. Streamed to your SIEM. Useful. We found no open tamper-proof method. | ◆ |
| Agent authorization | Each checked tool call passes a scope ceiling. A declared rights tier and a pull-back re-check come before dispatch. Cedar governs admin, config, and token decisions. | Rules evaluated at token issuance and exchange, plus ReBAC checks the app can call. Strong model. The check runs at the point of minting. Not at our dispatch point. | ◈ |
| Mid-session revocation | Re-checked on the next checked call. Revoke at 14:02, and the 14:02:30 call fails closed. | Short-lived tokens and request-path rule, per their XAA post. How fast a live agent loses access isn't stated in minutes. Ask them. | ◆ |
| Break-glass | Scoped, time-boxed emergency access for agents. It auto-revokes and can't be quietly removed from the log. | We couldn't find a break-glass method in their public docs. | ◆ |
| GDPR erasure | Crypto-shred of per-subject keys, plus ISO 27560 consent receipts. Actor identities carry an HMAC commitment. The chain still verifies after erasure. | Standard CIAM user delete. The effect on audit history isn't written down that we could find. | ◆ |
| Data handling | We tokenize datasets at ingest. Agents query tokenized data over MCP. Detokenization is a gated, audited run. Plus quasi-ID generalization. Dates become year, decade or age band. ZIPs become 3 or 4 digits. Phones, SSNs and emails get partial masking. Each column gets a measured cardinality-reduction score. | None by design. Descope is an identity platform. It gates who may ask, not what the answer contains. | ◆ |
| MCP and agents | Native MCP endpoints on Auth, Ontology, and Lighthouse. MCP tool tokens carry scope ceilings. Per-call metering ties back to the agent. | OAuth 2.1 protected MCP servers, with per-tool scopes and tenant isolation. DCR, JWT Bearer, a Python MCP SDK. Their own IDE MCP server too. | ◈ |
| Standards work | SAML, OIDC, WebAuthn passkeys, RFC 9068 JWTs, JWKS rotation. We consume standards. We don't write them. | Cross-App Access on ID-JAG, adopted as the Enterprise-Managed Authorization extension to MCP. Agent AI Foundation member. | ◇ |
| Credential vault | Connection Vault: encrypted per-subject credentials across eight strategies, plus Snowflake keypair JWT. | Connections: a vault for downstream OAuth tokens and API keys, with 50+ connectors. | ◈ |
| Developer experience | Docs and SDKs exist. They are not our strong suit, and we're not going to pretend otherwise. | Self-serve sign-up, visual Flows, widgets, SDKs, and docs people actually finish reading. | ◇ |
| Deployment | Self-hosted, in your own cloud or data center. Or on a dedicated single-tenant server we operate. Your keys. | SaaS. We found no self-hosted or dedicated single-tenant option. Ask them if that's a hard rule for you. | ◆ |
| Maturity signals | Auth, Guardian and Lighthouse are live in production. Guardian and Lighthouse have run since April 2026. SOC 2 is not yet certified, and we say so. | Founded 2022. Honorable Mention in the 2025 Gartner Magic Quadrant for Access Management. Shipping agent features each quarter since August 2025. | ◇ |
| Pricing | Open model, scoped instant quote, no sales wall. | Published too: Free at $0, Pro from $249/mo, Growth from $799/mo. We meter agent usage as consents, tokens, and M2M exchanges. Rare and welcome. | ◈ |

Descope claims come from descope.com, descope.com/pricing, their blog, and docs.descope.com. We checked last on 13 September 2026. We link the sources below rather than paraphrase from memory.
Three things you get here that you won't get from an identity platform
Proof, not just a log line
Descope will tell you which agent called which resource. It streams that to your SIEM. That's genuinely useful. It's also a mutable record, like each SIEM record. Ours is a hash chain with signed checkpoints. The checker says what broke: tamper, insertion, delete, or cut-short. That's the property EU AI Act Article 12 and HIPAA §164.312(b) reviewers keep asking about. Try it in your browser, no signup.
A check at the moment of use
Their rules fire at token minting or exchange. Ours fire again on each checked tool call: scope ceiling, rights tier, pull-back. An analyst leaves at 14:02, while their agent is 20 minutes into a 40-minute job. The next call is the one that matters. How Auth handles it.
Governance of the data, not only the door
An authorized agent asking a legitimate question can still pull 40,000 rows of PHI. Identity says yes. Tokenization decides what 'yes' returns. We tokenize at ingest, and gate detokenization as a gated, logged run. See the data layer.
Where Descope is genuinely stronger
Credit where it's due. Descope shipped an Agent Identity Control Plane in August 2025. Agent Identity Hub 2.0 followed in January 2026. Cross-App Access on ID-JAG landed in September 2026. It is now the Enterprise-Managed Authorization extension to MCP. They didn't just adopt that standard. They helped push it. Their FGA is ReBAC, with a local cache. Published numbers: 0.3 to 0.7 ms per check. It's built for an agent firing hundreds of lookups in one pass. Their free tier is real. Their prices sit on the site. A dev can have an MCP server behind OAuth 2.1 before lunch. We can't match the docs. Or the SDK range. Or the self-serve on-ramp. We won't claim we can.
Here's the push-back. Descope guards the door. Once an agent holds a valid token, their stack does not know this: the query behind it returns social security numbers. And nothing in their log stops a well-placed insider from editing the record after. Gartner expects most not allowed agent runs through 2028 to be internal rule breaks, not attacks. Those come from agents whose tokens were fully valid. That's the gap we sell into. It sits under their layer, not across from it.
Questions worth asking both of us
These are the questions we'd want answered if we were buying. Ask them on each vendor call, plus ours.
Can you cryptographically prove an audit log entry wasn't deleted?
DataShield: yes. Each record commits to the one before it. Checkpoints are Ed25519-signed and chained. Verification tells delete apart from cut-short and tamper. Run it on a sample chain at /verify. Descope: their docs describe an audit trail. It links each action to the originating user, and streams to your SIEM. We found no open tamper-proof method. Ask them to show one.
What happens to a revoked agent mid-session?
DataShield re-checks rights on each checked tool call. Pull-back lands on the next call. Descope leans on short-lived tokens. They say rule evaluates in the request path, not baked into a credential. The right instinct. What we couldn't find is a stated worst-case window. Ask both of us this. After I click revoke, how many more tool calls can that agent make?
How does GDPR erasure interact with the audit trail?
DataShield crypto-shreds per-subject keys, and issues an ISO 27560 consent receipt. Actor identities in the chain carry an HMAC commitment. The proof still verifies, even after the subject is gone. Descope supports user delete as any CIAM does. We found nothing on what that does to agent audit history. Ask whether erasing a subject breaks the log. Or keeps data you'd have to explain.
Is DataShield a Descope alternative for MCP server auth?
Partly, and we'd rather be straight about it. Say you want OAuth 2.1 on your MCP server. With DCR, token exchange, and a good SDK. Descope does that better today. Our MCP tool tokens carry scope ceilings and per-call metering attributed to the agent. A narrower, more opinionated thing. Teams building a product usually take Descope. Teams whose agents touch ruled data usually take us. Quite a few take both.
Do we have to rip out Descope to run DataShield?
No, and please don't. We federate over SAML and OIDC, and we're happy to be the relying party. The useful division is this. Descope proves who the agent is and issues the credential. DataShield decides whether each checked call against ruled data may proceed. It keeps verifiable proof that it was. Architecture notes.
Does DataShield have SOC 2?
Not yet, and we won't imply otherwise. Auth is live with a public threat model and a checker anyone can run. Guardian and Lighthouse have run in production since April 2026. Design-partner terms include source escrow. So a small vendor isn't a single point of failure. Details on the security page. We also couldn't load a Descope trust page on 13 September 2026. Ask them directly for their certifications, rather than taking our word for their absence.
