Head-to-head · updated 13 September 2026
DataShield vs Anomalo: who watches the tables, and who answers for the agent?
Anomalo does one hard thing very well. Point it at a warehouse. It learns what a table normally looks like. Then it flags when the table stops looking like that. No rules to write. No thresholds to guess. They call the current version "the autonomous data system for the agentic enterprise". They ship nine named agents with it. Snowflake and Databricks both put money in. The Snowflake Native App runs inside your own account. That is a good product, with good backing. We will not squint at it.
We do not detect anomalies. DataShield has no monitors on your warehouse tables. No freshness SLAs. No issue queue. We would rather say that up front than bury it. What we do is govern the data your agents actually read. We tokenize datasets at ingest. Agents then query tokenized data over MCP. Turning a token back into real data is a special step. It's always audited. We re-check every checked tool call against current access. That happens before it runs. Every choice lands in a hash chain. Anyone can check it. Below is the honest split. It includes the rows Anomalo wins.
The short version
Pick DataShield when
- Someone will ask you to prove an agent's access log was not edited. An auditor, an examiner, or Article 12 of the EU AI Act. Our chain answers with math, not a policy PDF. Run the verifier.
- You need to pull an agent's access mid-session. The very next tool call should fail. Not the next token refresh. The next call.
- Sensitive fields must be tokenized before an agent, or a prompt, ever sees them. Detokenization has to be a logged, privileged act.
- The whole thing has to run on your own hardware. On your own keys. Outside any one cloud vendor's estate.
Pick Anomalo when
- Your actual pain is a broken table at 3am. Unsupervised ML that learns normal beats a hand-written rule suite. This is the job they were built for.
- You live in Snowflake or Databricks. Both invested in them. The Snowflake Native App runs in your own account. The integration depth shows.
- You want incident workflow: Slack and Teams alerts, PagerDuty, Opsgenie, Jira, ServiceNow, root-cause investigation. We have none of that.
- Procurement wants SOC 2 Type 2 and HIPAA on the vendor questionnaire, today. They have both. We do not.
Bottom line: Anomalo tells you the data is wrong. DataShield decides whether an agent may read it. It keeps proof of the decision, too. Most teams should run both. Already own a monitoring tool? Evidence is the gap you have left.

| What matters | DataShield | Anomalo | Edge |
|---|---|---|---|
| Anomaly detection and monitoring | None. We have no statistical anomaly detector. No table monitors, no freshness SLA, no alert routing. If a row count halves overnight, nothing here pages you. | The core product, and a mature one. Unsupervised ML learns each table's normal shape. It flags drift without hand-written thresholds. No-code checks sit alongside it too, for teams that still want explicit rules. | ◇ |
| Profiling and trust scoring | Every dataset gets a 20-section analysis profile. It covers completeness, field stats, patterns, and column meaning. Also a relationship graph and quality numbers. Plus lineage, business rules and a source fingerprint. A trust score rolls up on top. One per entity type, per domain, and across the estate. It's recomputed each hour, with a trend line. | Deep per-table quality metrics, root-cause digging, and a docs agent. It's a monitoring output. Not a catalog profile. | ◈ |
| Sensitive field classification | 129 field classes, with fixed, repeatable verdicts. It covers PII, PHI, financial data and secrets. All 18 HIPAA Safe Harbor IDs are their own classes. Each carries a rule reference. A source fingerprint shows where a dataset came from. | Their unstructured product uses an LLM. It flags sensitive PII inside docs and transcripts. Plus 15 or more other doc checks. They do not sell column-level classification of warehouse tables. | ◆ |
| Audit evidence | SHA-256 row chain, with Ed25519-signed checkpoints. Those checkpoints are themselves chained. Verification returns one of three verdicts. It names the failure: tampering, insertion, deletion, or a cut-off tail. Try the verifier. | Alerting, issue history and investigation trails. We found no published crypto proof of tamper evidence there. | ◆ |
| Agent authorization | Every checked tool call passes a scope ceiling. Plus a consented-tool allowlist. Plus an access tier. We re-check for revocation before dispatch. It fails closed. Delegation runs on RFC 8693 token exchange. It carries its own enforced scope ceiling. | Not part of the product. Their agents run inside their own platform. We found no authorization layer for your agents. | ◆ |
| Break-glass | Scoped, time-boxed emergency access for agents. Admin, plus IP allowlist, plus step-up checks. It auto-revokes. Nobody can quietly delete it from the log. | Not described anywhere on their site. | ◆ |
| GDPR erasure | Crypto-shred of per-subject key material. Cited to ISO/IEC 27040 and GDPR Article 17. Plus ISO 27560 consent receipts. The audit chain still checks out afterwards. | Their doc checks can spot a client asking to be removed. Or asking for erasure under GDPR or CCPA. That is just spotting the request. The erasure itself is someone else's job. | ◆ |
| Tokenization and masking | Deterministic, join-preserving, vault-reversible tokens at ingest. Plus generalization for quasi-identifiers, as a rule. Dates become year, decade, or age band. ZIPs become 3 or 4 digits. Phones, SSNs and emails get partial masking too. Each column gets a measured score. Detokenization is a special act. Each lookup gets audited or refused. | Not part of the product. They read your data to score it. They do not change it. | ◆ |
| MCP and agents | More than 200 MCP tools across Ontology, Auth, Corpus and Lighthouse. Auth issues MCP tool tokens with scope ceilings. It meters each call, tied to the agent. | Nine named agents, four of them marked coming soon. A chat-based copilot called AIDA runs them. These are Anomalo's own agents, doing Anomalo's own work. We found no MCP server. No tool surface your own agents can call, either. | ◆ |
| Prompt path | We do not proxy your LLM traffic. We do gate each value headed for a prompt. A PHI dataset refuses an endpoint with no BAA. A classified column with no set treatment gets redacted. It never just passes through. | They use LLMs to score your docs. They say the data stays in a locked-down setup, and that it does not train outside models. That's a different direction of travel. They send data to a model, to judge it. | ◆ |
| Deployment | Self-hosted, in your own cloud or data center. Or a dedicated single-tenant server we operate. Docker images cover Auth, Ontology, Corpus and Lighthouse. Each has a signed deploy manifest, and Guardian checks it. Ed25519 keys stay on your instance. In a key folder you control. Kid-keyed rotation fails closed on an unknown key. Auth has a built seam for KMS or HSM custody. No shipped link yet. HMAC tokenization keys sit on your system today. Or they derive from your machine key. Not in a KMS. | SaaS, plus a Snowflake Native App on Snowpark Container Services. It runs inside your own account. That way, monitored tables never leave it. Marketplace listings on Google Cloud and Azure too. Strong, if your estate is Snowflake-shaped. | ◈ |
| Connector breadth | We scan, profile and classify a live PostgreSQL source in place. No rows leave it. That is PostgreSQL today, not your whole estate. Snowflake, BigQuery, Databricks, S3 and Salesforce are listed. No handler yet. | Seventeen warehouses and databases. Eight catalogs, including Collibra, Alation, Atlan and Unity Catalog. Eight alerting and ticketing targets. Three BI tools, plus Airflow and dbt. Not close. | ◇ |
| Maturity signals | Auth, Guardian and Lighthouse are live and in use. Guardian and Lighthouse since April 2026. SOC 2 not yet certified. We say so. | Founded 2018. About $82M raised. Strategic money from both Databricks Ventures and Snowflake Ventures. A Gartner Peer Insights Strong Performer badge, in December 2025. Logos like Discover, Equifax, Atlassian and Notion. SOC 2 Type 2 and HIPAA claimed in their site footer. | ◇ |
| Pricing | Published model, scoped instant quote, no sales wall. | Quote only. G2 and SpotSaaS both list custom pricing, with no free trial. We found no third-party estimate. | ◆ |

Three things you get here that you won't get from a data observability platform
Proof that survives an audit
A log you can edit in silence proves nothing. Ours is a hash chain, with signed checkpoints. The verifier says what broke, not just that something did. EU AI Act Article 12 and HIPAA §164.312(b) reviewers ask about that. Try it in your browser, no signup.
Authority that can change mid-flight
An analyst leaves on a Friday. Their agent is 20 minutes into a 40-minute job. With DataShield, we re-check the next checked tool call. Against current access. It fails closed. A monitoring tool writes you a nice issue about it. On Monday. How Auth does it.
The values themselves, governed
Quality scoring reads your data. We change what the agent can read, at all. Tokens at ingest. Generalized quasi-identifiers. A fail-closed gate on anything headed for a prompt. What Ontology does with a dataset.
Where Anomalo is genuinely stronger
Unsupervised anomaly detection is harder than it sounds. Anomalo has been at it since 2018. Writing quality rules by hand does not scale. Not past a few hundred tables. Everyone who has tried knows it. Their approach learns each table's normal behavior instead. Then it flags the deviation. That's why names like Discover and Equifax sit on the logo list. Their reach is real too. Databricks Ventures and Snowflake Ventures both invested. The Snowflake Native App runs inside the client's own account. The integrations page lists more warehouses, catalogs and alerting targets. Far more than we will ship for years. Their unstructured product is clever. It scores docs with an LLM. It surfaces things like sensitive PII in support transcripts. And they hold SOC 2 Type 2 and HIPAA attestations. We hold neither yet. A procurement team is right to weigh that in.
Here is the push-back. Detection and evidence are different duties. Only one of them has a regulator attached. Anomalo will tell you a doc contains PII. It will not stop an agent from reading that doc. It will not tokenize the field first. It cannot hand an examiner a log that is provably unedited. Their nine agents work on your data. On their behalf, not on yours. We found no MCP server. No tool surface a client's own agent can call, either. That's a strange gap for a product sold to "the agentic enterprise." Say your AI runs live now. Say it touches regulated data. The question that bites first: not whether the table looks odd. It is who let the agent in. And whether you can prove what it did.
Questions worth asking both of us
These are the questions we would ask, if we were buying. Ask them on each call, ours included.
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 against a sample chain at /verify. Anomalo: their site describes alerts, issues and investigation history. We found no tamper-evidence method. Ask them to show one.
What happens to a revoked agent mid-session?
DataShield re-checks access on each checked tool call. So revocation lands on the next call. Not the next token refresh. Anomalo does not sell agent access control. So the honest answer is: this is not their layer. Ask whoever owns it in your stack. How long does a revoked agent keep working?
How does GDPR erasure interact with the audit trail?
DataShield crypto-shreds per-subject key material and issues an ISO 27560 consent receipt. The chain HMAC-commits actor IDs, not names. So the evidence still checks out once the subject is gone. Anomalo's unstructured checks can flag it. A client asking for erasure inside a transcript. That's really useful as a trigger. Carrying out the erasure is one thing. Keeping the audit trail valid afterwards is another. Their site claims neither.
Is DataShield a data observability tool? Do we drop Anomalo?
No, and no. We have no anomaly detection. No monitors on your warehouse tables. No freshness SLAs. There's no issue management either. If pipeline breakage is your problem, buy a monitoring tool. Run us for the checked datasets agents read. There, the job is authorization and evidence. Plenty of teams will sensibly run both.
Anomalo ships nine agents. Isn't that agent-native?
It is agent-built, not agent-open. Their agents monitor, investigate and log your data. AIDA is the chat layer that ties them together. We found no way for your agent to call their platform. Not as a tool. Ours works the other way round. More than 200 MCP tools. Tokens with scope ceilings. Per-call metering, tied to the agent. Ask them for the MCP endpoint. See what comes back.
Does DataShield have SOC 2?
Not yet, and we will not imply otherwise. Anomalo does, along with HIPAA. What we offer instead is a public threat model. A verifier anyone can run. Source escrow in design-partner terms. That way, a small vendor is not a single point of failure. Auth is live. Guardian and Lighthouse have been live since April 2026. Details on the security page.
