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 back in 2021. They solved a real, boring problem: static credentials sitting in CI/CD. Then they pointed that machinery at agents. Their MCP Identity Gateway hands an agent access. The agent never touches the credential itself. Say your nightmare is a Snowflake password sitting in an agent's environment variables. Go read their docs.
DataShield starts one step further in. We tokenize datasets at ingest. Agents query tokens over MCP, not raw data. Turning a token back into real data is a privileged, audited step. We re-check each checked tool call against the agent's current access. We seal each call into a hash chain. You can check it yourself, without trusting us. Aembit checks the connection. We check the data, and we keep the evidence. Here's the honest split. It includes 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. A leaked result set is just a list of
TOK_strings. How the data plane works. - You need to pull an agent's access mid-session. You want the very next checked tool call to 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, both included. Architecture.
Pick Aembit when
- Static secrets are the fire you're fighting. Secretless access is their home turf. The credential never reaches the agent runtime. 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. It's a genuinely good idea.
- You need SOC 2 and ISO 27001 on the contract today. Plus CrowdStrike, Snowflake and Copilot Studio ties, 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, not just hygiene, start here.
Feature by feature
Competitor cells describe what Aembit's public site, pricing page and press releases say. We use the date above. If we got something wrong, email support@myorg.ai. We'll fix it and credit you.
| What matters | DataShield | Aembit | Edge |
|---|---|---|---|
| Audit evidence | SHA-256 hash chain with Ed25519-signed checkpoints. We chain the checkpoints too. A check names the failure: tampering, insertion, deletion, or a cut-off tail. Try the verifier. | "Structured event recording for full traceability." Logs separate human access from agent access. Posted tiers cap event log retention: 24 hours on Starter, 7 days on Teams. Custom retention on Enterprise. We found no crypto proof against tampering. | ◆ |
| Agent authorization | Each checked tool call passes a scope ceiling. Plus a set access tier. Plus a re-check that access wasn't pulled, before it runs. Cedar covers admin, config and token calls. Each one gets policy_explain. | Runtime policy checks at the MCP Identity Gateway. Short-lived credentials, plus "immediate permission revocation when needed". They describe the policy model in general terms. They don't write up a per-call access re-check. | ◆ |
| Break-glass | Scoped, time-boxed emergency access for agents. It auto-revokes. No one can quietly delete it 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. We HMAC-commit actor identities. The chain still checks out once the subject is gone. | Not described. Their layer holds access events, not subject data. 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 become year, decade or age band; ZIPs become 3 or 4 digits; we mask phones, SSNs and emails in part. Each column gets a cardinality-reduction score. Turning a token back into real data is a privileged, logged step. | 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 ways, including Snowflake keypair-JWT. We encrypt credentials per subject and issue them 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. A dedicated SPIFFE Credential Provider shipped in November 2025. Real fit with what platform teams already run. | ◇ |
| Human-to-agent binding | Agent tokens carry the issuing subject. They link through the audit chain. You can trace a call back to a person. | Blended Identity gives the agent a checked identity. It binds to the human it stands in for. A named product doing one clear thing beats our link-based story, on paper. | ◇ |
| MCP and agents | Native MCP endpoints on Auth, Ontology and Lighthouse. MCP tool tokens with scope ceilings. Per-call metering, tied to the agent. | MCP Identity Gateway with authorization rules. Plus a CrowdStrike tie that checks MCP tool listings, inputs and outputs. Strong here. | ◈ |
| Deployment | Self-hosted, or a dedicated single-tenant server. Your keys, your Postgres, your audit chain. | SaaS control plane ("Get an Aembit Tenant"). Multi-cloud, across AWS, Azure and GCP. They say it's on-premises compatible. Ask exactly which parts run in your account. | ◆ |
| Maturity signals | Auth, Guardian and Lighthouse are live in production. Guardian and Lighthouse have run since April 2026. SOC 2 isn't certified yet, and we say so plainly. | Founded 2021. $16.6M seed, with Okta Ventures. SOC 2 and ISO 27001. Snowflake as customer and partner. CrowdStrike and Microsoft ties, plus an industry award. They're further along. | ◇ |
| Pricing | Published model, scoped instant quote, no sales wall. | Posted 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
We draw Aembit claims from aembit.io. Also from their pricing page and their own press releases. Last checked 13 September 2026. We link them below, not just 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 sits behind the door. Here we tokenize the dataset at ingest. We generalize quasi-identifiers too. Turning a token back into real data is a separate, privileged call. We log it. 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. The verifier tells you what went wrong, not just that something did. That's what EU AI Act Article 12 and HIPAA §164.312(b) reviewers ask about. Try it in your browser, no signup.
Access that changes mid-flight
An analyst leaves at 2pm. Their agent is 20 minutes into a 40-minute job. Short-lived credentials still run until they expire. With DataShield, we re-check the next call against current access. It 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 tie shipped on 1 September 2026. Copilot Studio support, too. A GitLab part for secretless CI/CD. Their SPIFFE Credential Provider is the right kind of engineering. Join the standard. Don't reinvent it. And Blended Identity, tying an agent's identity to the human it acts for, is the single best idea in their product. We do roughly the same thing, through token subjects and audit links. That works, but it reads less clean on a slide.
Here's the push-back. Aembit's answer ends where the credential gets 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 bad agent actions through 2028 to be policy breaks from inside, not attacks. That means the agent will be correctly signed in 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. Most teams who buy us keep their workload identity stack right where it is.
Questions worth asking both of us
These are the questions we'd want answered if we were buying. Ask them on each 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. We sign and chain each checkpoint. A check tells deletion apart from truncation and tampering. Run it at /verify. Aembit: their launch describes "structured event recording for full traceability". Their pricing page lists retention as 24 hours on Starter, 7 days on Teams, custom on Enterprise. We found no tamper-proof mechanism. Ask them to show one, and ask what retention costs.
What happens to a revoked agent mid-session?
DataShield re-checks access on each checked tool call. A pull lands on the next call. Aembit's launch lists "immediate permission revocation when needed" and issues short-lived credentials, which shrinks the window a lot. We couldn't find whether an issued credential gets re-checked before each MCP tool call. It may just expire. That gap 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. We HMAC-commit actor identities in the chain. The evidence stays checkable once the subject is gone. Aembit holds access events, not subject data. Erasure of the underlying records lands on your own 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 we never fight your directory. Where we compete head-on 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. Say you're only funding one. If your risk is regulated data, not 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. What the agent queries over MCP never held the raw value. Turning a token back into real data is a privileged, audited step. The trade-off is honest: if you want a gateway that checks MCP tool inputs and outputs live, 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 ships live, with a posted threat model and a verifier 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.
