Head-to-head · updated 13 September 2026
DataShield vs Aembit: who holds the agent's credential, and who can prove what it did?
Aembit sells "IAM for Agentic AI", and they earned the phrase. They started on workload identity in 2021, solved the boring, real problem of static credentials in CI/CD, then pointed that machinery at agents. Their MCP Identity Gateway hands an agent access without the agent ever touching the credential. If your nightmare is a Snowflake password sitting in an agent's environment variables, go read their docs.
DataShield starts one step further in. Datasets are tokenized at ingest; agents query tokenized data over MCP; detokenization is a privileged, audited operation. Every governed tool call is re-checked against the agent's current authority, and every decision is sealed into a hash chain you can verify without trusting us. Aembit governs the connection. We govern the data and the evidence. Here's the honest split, including the rows they win.
The short version
Pick DataShield when
- The data itself is the risk, not just the credential. Agents here query tokenized datasets, so a leaked result set is a list of
TOK_strings. How the data plane works. - You need to pull an agent's authority mid-session and have the very next governed tool call fail, not the next credential refresh.
- An examiner will one day ask you to prove the March logs weren't edited. Our chain answers with math. Run the verifier.
- Your keys, your infrastructure, your control plane. We self-host the whole stack, policy engine and evidence included. Architecture.
Pick Aembit when
- Static secrets are the fire you're fighting. Secretless access, where the credential never reaches the agent runtime, is their home turf and they've been at it since 2021.
- You already run SPIFFE, Kerberos or OIDC workload federation. They interoperate with those instead of asking you to rip them out. We don't attest workloads that way.
- You want an agent identity bound to the human it acts for. Their Blended Identity does that by design, and it's a genuinely good idea.
- You need SOC 2 and ISO 27001 on the contract today, plus CrowdStrike, Snowflake and Copilot Studio integrations off the shelf.
Bottom line: Aembit makes sure the agent never holds the key. DataShield makes sure the data the agent sees is already tokenized, the call is allowed right now, and the record of it can't be quietly rewritten. If your board asked for proof rather than hygiene, start here.

| What matters | DataShield | Aembit | Edge |
|---|---|---|---|
| Audit evidence | SHA-256 hash chain with Ed25519-signed checkpoints that are themselves chained. Verification names the failure: tampering, insertion, deletion, or truncation. Public verifier. | "Structured event recording for full traceability", and logs that separate human from agent-initiated access. Published tiers cap event log retention at 24 hours on Starter and 7 days on Teams, with custom retention on Enterprise. We found no cryptographic tamper evidence. | ◆ |
| Agent authorization | Every governed tool call passes a scope ceiling, a declared authority tier, and a revocation re-check before dispatch. Cedar covers admin, config and token decisions with policy_explain on each one. | Runtime policy enforcement at the MCP Identity Gateway, with ephemeral credentials and "immediate permission revocation when needed". The policy model is described generically. No per-tool-call authority re-check is documented. | ◆ |
| Break-glass | Scoped, time-boxed emergency access for agents that auto-revokes and can't be quietly deleted from the log. | We couldn't find break-glass in their public docs. Worth asking them. | ◆ |
| GDPR erasure | Crypto-shred of per-subject key material plus ISO 27560 consent receipts. Actor identities are HMAC-committed, so the chain still verifies after the subject is gone. | Not described. Their layer holds access events, not subject data, so erasure lands on you and on whatever system stores the rows. | ◆ |
| Data handling and tokenization | Deterministic, join-preserving, vault-reversible tokens applied at ingest, plus quasi-identifier generalization (dates to year, decade or age band; ZIPs to 3 or 4 digits; partial phones, SSNs and emails) with a measured cardinality-reduction score per column. Detokenization is a privileged, logged operation. | None. Aembit brokers access to a resource; the rows that come back are whatever the resource holds. That's a design choice, not a gap in their category. | ◆ |
| Secretless credentials | Connection Vault with 7 credential strategies, including Snowflake keypair-JWT. Credentials are encrypted per subject and issued server side. | The whole thesis. Token exchange at the gateway means the credential never enters the agent runtime. Cleaner story than ours, and better marketed. | ◇ |
| Workload attestation | SAML, OIDC, WebAuthn passkeys and API keys for identity. We don't attest cloud workloads by platform signature. | OAuth, OIDC, SPIFFE and Kerberos, with a dedicated SPIFFE Credential Provider shipped in November 2025. Real interoperability with what platform teams already run. | ◇ |
| Human-to-agent binding | Agent tokens carry the issuing subject and correlate through the audit chain, so you can trace a call back to a person. | Blended Identity gives the agent a verified identity bound to the human it represents. A named product doing one clear thing beats our correlation story on presentation. | ◇ |
| MCP and agents | Native MCP endpoints on Auth, Ontology and Lighthouse. MCP tool tokens with scope ceilings, and per-call metering attributed to the agent. | MCP Identity Gateway with authorization policies, plus a CrowdStrike integration that inspects MCP tool listings, inputs and outputs. Strong here. | ◈ |
| Deployment | Self-hosted or dedicated single-tenant. Your keys, your Postgres, your audit chain. | SaaS control plane ("Get an Aembit Tenant"), multi-cloud across AWS, Azure and GCP, described as on-premises compatible. Ask exactly which parts run in your account. | ◆ |
| Maturity signals | Auth, Guardian and Lighthouse are live in production (Guardian and Lighthouse since April 2026). SOC 2 not yet certified, and we say so. | Founded 2021, $16.6M seed with Okta Ventures, SOC 2 and ISO 27001, Snowflake as customer and partner, CrowdStrike and Microsoft integrations, an industry award. They're further along. | ◇ |
| Pricing | Published model, scoped instant quote, no sales wall. | Published too, and clear: free Starter, $20 per agent per month on Teams for 10 to 500 agents, custom Enterprise. Credit where it's due, most of this market hides behind a demo form. | ◈ |
◆ DataShield leads◇ Aembit leads◈ comparable
Aembit claims are drawn from aembit.io, their pricing page and their own press releases, last checked 13 September 2026. We link them below rather than paraphrase from memory. We could not confirm a Series B or a total funding figure in their newsroom.
Three things you get here that you won't get from a workload IAM
Data that's already tokenized
A credential broker decides whether the agent may open the door. It doesn't change what's behind the door. Here the dataset is tokenized at ingest, quasi-identifiers are generalized, and detokenization is a separate privileged call that gets logged. The worst case is a set of TOK_ values. See the data layer.
Proof that survives an audit
Event logs with a seven-day retention tier are telemetry, not evidence. Ours is a hash chain with signed checkpoints, and the verifier tells you what went wrong, not just that something did. That's the property EU AI Act Article 12 and HIPAA §164.312(b) reviewers ask about. Try it in your browser, no signup.
Authority that changes mid-flight
An analyst leaves at 2pm. Their agent is 20 minutes into a 40-minute job. Ephemeral credentials still run until they expire. With DataShield the next governed tool call is re-checked against current authority and fails closed. How Auth does it.
Where Aembit is genuinely stronger
Start with the obvious. Aembit has SOC 2 and ISO 27001, we don't yet. They have Snowflake as a named customer and a partner, a CrowdStrike integration shipped on 1 September 2026, Copilot Studio support, and a GitLab component for secretless CI/CD. Their SPIFFE Credential Provider is the right kind of engineering: join the standard, don't reinvent it. And Blended Identity, binding an agent's identity to the human it acts for, is the single best idea in their product. We do the equivalent through token subjects and audit correlation, which works but is less legible on a slide.
Here's the push-back. Aembit's answer ends where the credential is handed over. The gateway checks policy, swaps a token, writes an event. Then the query runs and raw rows come back to a model. Gartner expects most unauthorized agent transactions through 2028 to be internal policy violations rather than attacks, which means the agent will be correctly authenticated when the bad thing happens. So you need two things a broker can't give you. Data that was never raw. And a log nobody can edit later. That's the layer we sell, and most teams who buy us keep their workload identity stack exactly where it is.
Questions worth asking both of us
These are the questions we'd want answered if we were buying. Ask them on every vendor call, including 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, and verification tells deletion apart from truncation and tampering. Run it at /verify. Aembit: their launch describes "structured event recording for full traceability", and their pricing page lists retention as 24 hours on Starter, 7 days on Teams, custom on Enterprise. We found no tamper-evidence mechanism. Ask them to show one, and ask what retention costs.
What happens to a revoked agent mid-session?
DataShield re-checks authority on every governed tool call, so revocation lands on the next call. Aembit's launch lists "immediate permission revocation when needed" and issues short-lived credentials, which shortens the window a lot. What we couldn't find is whether an already-issued credential is re-evaluated before each MCP tool call or simply expires. That difference is minutes versus one call. Ask them.
How does GDPR erasure interact with the audit trail?
DataShield crypto-shreds per-subject key material and issues an ISO 27560 consent receipt. Actor identities in the chain are HMAC-committed, so the evidence stays verifiable after the subject is gone. Aembit holds access events rather than subject data, so erasure of the underlying records lands on your systems. Ask both of us what breaks when a subject asks to be forgotten.
Is DataShield an Aembit alternative, or do we run both?
Both is reasonable and fairly common. If you already use Aembit to keep credentials out of agent runtimes, keep it. We federate identity over SAML and OIDC and never fight your directory. Where we compete directly is the enforcement seam: which system decides the agent may make this call, right now, and which system holds evidence you could hand an examiner. If you're only funding one and your exposure is regulated data rather than credential sprawl, pick us.
Aembit has an MCP Identity Gateway. Why doesn't DataShield sit inline?
Because inline means raw data was in the path. We tokenize datasets at ingest, so what the agent queries over MCP never contained the raw value, and detokenization is a privileged, audited operation. The trade-off is honest: if you want a gateway that inspects MCP tool inputs and outputs in real time, especially with CrowdStrike AIDR behind it, Aembit does that and we don't.
Does DataShield have SOC 2?
Not yet, and we won't imply otherwise. Aembit has SOC 2 and ISO 27001 today, which is a fair reason to pick them. Auth is live a public threat model and a verifier anyone can run. Guardian and Lighthouse have been 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.
