Head-to-head · updated 13 September 2026
DataShield vs HashiCorp Vault: who hands the agent the key, and who proves what it opened?
Vault is the default secrets manager. There's a reason for that. Dynamic secrets, PKI, key custody. Now agentic IAM too. It went GA on 1 September 2026. It registers each agent. It hands out a token good for one request. Then it caps that with a ceiling policy. That's good work. We're not going to pretend otherwise.
We sit one layer over. We tokenize datasets at ingest. Agents query tokenized data over MCP. Turning a token back into real data is a privileged step. It's audited, always. We re-check each checked tool call. Each choice seals into a hash chain. You can verify it yourself. Below is the honest split. It includes the rows Vault wins.
The short version
Pick DataShield when
- Someone will one day ask you to prove an agent's log was not edited. Our chain answers with math. Not a policy PDF. Run the verifier.
- The risk you care about is the data the agent reads, not the credential it used to get there. We tokenize the dataset. The raw value never sits in the query surface.
- You need break-glass for an agent. A scoped, time-boxed grant. It expires on its own. It can't be quietly wiped from the log.
- A subject asks to be erased. Your auditor still wants March's records. Crypto-shred gives you both. How that works.
Pick HashiCorp Vault when
- You need secrets management proper: dynamic database credentials, cert lifecycle, key rotation, encryption as a service. This is their home turf. We don't compete for it.
- FF3-1 encryption that keeps a value's original shape and length matters to you. Their Transform engine does it. Ours doesn't do FPE at all. We won't say otherwise.
- You have secret sprawl. Vault Radar scans repos and collaboration tools. It names secrets leaked into AI agent configs, LLM prompts, and agentic workflow definitions. Nobody else phrases it that precisely.
- You want one vendor with IBM behind it. A huge install base. A Terraform provider your platform team already uses.
Bottom line: most teams should run both. Vault holds the secrets and the keys. DataShield decides what an agent may do with the tokenized data. It keeps proof it was allowed, too.

| What matters | DataShield | HashiCorp Vault | Edge |
|---|---|---|---|
| Audit evidence | A SHA-256 hash chain, with Ed25519-signed checkpoints. We chain those checkpoints too. Verification names the failure: tampering, insertion, deletion, or truncation. Try the verifier. | Audit devices log each API request and response. HMAC-SHA256 keyed hashes cover most string values. Their audit docs describe no chaining. No signing of the stream, either. | ◆ |
| Agent authorization | Each checked tool call passes a scope ceiling. Plus an authority tier. It gets a re-check before dispatch. A pulled grant lands mid-session, not at token expiry. | Agentic IAM, GA 1 Sep 2026. Request-scoped tokens and agent ceiling policies. Authorization scores as a three-way intersection: user permissions, ceiling, and RFC 9396 authorization_details. Genuinely close to what we do. | ◈ |
| Break-glass | Scoped, time-boxed urgent access for agents. It auto-revokes. It can't be quietly deleted from the log. | Root tokens and recovery keys protect the vault itself. We found no agent-level urgent-access grant. Not in their public docs. | ◆ |
| GDPR erasure | Crypto-shred of per-subject key material, plus ISO 27560 consent receipts. Actor IDs carry HMAC commitments. The chain still verifies after erasure. | Key deletion and lease revocation exist. The effect on audit history isn't described. | ◆ |
| Tokenization and data transforms | 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. Phones, SSNs, and emails get partial masking. Each column gets a measured cardinality-reduction score. No FPE. | Transform secrets engine: FF3-1 encryption. It preserves a value's format and length. Plus masking and convergent tokenization. Broader than ours. It needs Vault Enterprise with the ADP-Transform module. So it's a paid add-on. | ◇ |
| Secrets, PKI, key custody | Connection Vault holds encrypted per-subject credentials. Eight strategies, six categories, including Snowflake keypair-JWT. Built for agent-to-data-platform links. Not for the whole estate. | Dynamic secrets, certificate lifecycle, key management, encryption as a service. The category benchmark. | ◇ |
| Secret sprawl scanning | Not offered. We don't scan your repos. | Vault Radar inspects code repos and collaboration tools. It finds unsecured credentials. That includes secrets in AI agent configs and LLM prompts. Or agentic workflow definitions. | ◇ |
| 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. | No MCP server surface found in their public docs. Note the naming trap. Vault Agent is a client-side daemon. It handles auth, caching, and templating. It has nothing to do with AI agents. | ◆ |
| Deployment | Self-hosted in your own cloud or data center. Or on a dedicated single-tenant server we operate. Your keys. | Community, Enterprise, and HCP managed cloud. The widest deployment spread of anyone in this set. | ◈ |
| Licensing and lock-in | Small vendor, and we know it. Design-partner terms include source escrow. | Moved from MPL 2.0 to BSL 1.1 in August 2023. That produced the OpenBao fork. It's now a Vault fork under the Linux Foundation's OpenSSF. HashiCorp signed its acquisition agreement with IBM in April 2024. Judge both for yourself. | ◈ |
| Maturity signals | Auth, Guardian and Lighthouse are live in production. Guardian and Lighthouse have run since April 2026. SOC 2 isn't certified yet. We say so plainly. | Vault shipped in 2015. It runs in a large share of the Fortune 500. Now it has IBM's balance sheet behind it. No contest. | ◇ |
| Pricing | Published model, scoped instant quote, no sales wall. | Vault pricing is quote-only across Community, Enterprise, and HCP. Their pricing page lists per-resource figures for Terraform. Not for Vault. | ◆ |

Three things you get here that you won't get from a secrets manager
A log you can prove was not edited
Vault writes a strong audit trail. It even refuses to serve a request it can't log. We admire that. But writing isn't proving. Ours is a hash chain with signed checkpoints. The verifier says what broke, not just that something did. That's the property EU AI Act Article 12 reviewers care about. HIPAA §164.312(b) reviewers too. Try it in your browser.
The data, not just the key
A short-lived credential is still a credential. It still opens a table full of real names. We tokenize the dataset at ingest. The agent queries tokens instead. Turning one back into a name is a separate step. Privileged, and logged. How the data layer works.
Break-glass for an agent
It's 2am. The on-call agent needs one table it isn't scoped for. You can hand out a root token and hope. Or you can grant scoped access. It expires on its own. It leaves a record nobody can quietly remove. We picked the second. How Auth does it.
Where HashiCorp Vault is genuinely stronger
Let's be straight about the last few months. In June 2026 Vault put per-request agent authorization into public preview. It's built on OAuth 2.0 Rich Authorization Requests. Ceiling policies, plus Terraform resources to register agents. In September it went GA as agentic IAM. Delegated JWTs carry the user as subject. The agent is the actor. That's not a press release dressed up as a feature. It's close to the seam we sell. A Vault shop can get a long way with it. Add Transform's FF3-1 encryption and Vault Radar. A decade of dynamic secrets comes with it. IBM sits behind the roadmap too. The gap in raw platform isn't close.
Here's the push-back. Vault answers who the agent is. And what it may reach. It doesn't change the data the agent then reads. It doesn't make the record provable to a third party. A keyed hash protects a secret inside a log line. It says nothing about line 4,102 vanishing last Tuesday. Ask both of us to delete a person. Keep the audit trail. Ask both of us for an urgent grant. One that expires by itself. Those are the questions where the answers actually diverge.
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 checkpoints. Verification tells deletion apart from truncation and from tampering. Run it on a sample chain at /verify. Vault: their audit docs describe keyed HMAC-SHA256 hashing. Of string values. Plus a guarantee. At least one audit device gets the entry. We found no chaining or signing of the log itself. Ask them to show tamper evidence.
What happens to a revoked agent mid-session?
DataShield re-checks authority on each checked tool call. Revocation bites on the next call. Vault's agentic IAM issues a token. Good for one request only. That gets you to a similar place. By a different route. This row is close to even. The fair question for both of us: what can it still read from a cache? Ask that after you pull access.
If Vault already does agent ceiling policies, why add DataShield?
Because a ceiling limits reach, not exposure. Vault's ceiling says the agent may call this path. It doesn't decide that row 12 comes back as a token. We tokenize at ingest. We keep that privileged and logged, too. Then we seal each choice into a verifiable chain. Run both. Vault for the credential. Us for the data and the evidence.
How does GDPR erasure interact with the audit trail?
DataShield crypto-shreds per-subject key material. Then it issues an ISO 27560 consent receipt. Actor IDs in the chain carry HMAC commitments. The evidence still checks out. Even once the subject is gone. Vault can delete keys and revoke leases. What that does to audit history isn't spelled out. Not in their docs. Ask whether erasing a person breaks the log.
Does the BSL change matter to us? Or the IBM deal?
It depends how much open source matters to your board. HashiCorp moved from MPL 2.0 to BSL 1.1 in August 2023. The OpenBao fork now lives under the Linux Foundation's OpenSSF. HashiCorp signed the IBM acquisition agreement in April 2024. None of that makes Vault a worse product. It does mean a free substitute exists. For the secrets layer. Worth knowing before you sign a multi-year floor.
Does DataShield have SOC 2?
Not yet, and we won't imply otherwise. Auth is live. It ships with 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. That way, a small vendor isn't a single point of failure. Details on the security page.
