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 and it learns what a table normally looks like, then tells you 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" and ship nine named agents to go with it. Snowflake and Databricks both put money in, and the Snowflake Native App runs inside your own account. That is a good product with good backing, and we are not going to squint at it.
We do not detect anomalies. DataShield has no monitors on your warehouse tables, no freshness SLAs, no incident queue, and we would rather say that in the first paragraph than bury it. What we do is govern the datasets your agents actually read. 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 before it runs, and every decision lands in a hash chain anyone can verify. Below is the honest split, including 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 authority mid-session and have the very next tool call fail. Not the next token refresh. The next call.
- Sensitive fields must be tokenized before an agent or a prompt ever sees them, and 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, and 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, and 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 and keeps proof of the decision. Most teams should run both, and if you already own a monitoring tool, the gap you have left is evidence.

| 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 and flags drift without hand-authored thresholds. No-code checks sit alongside it for teams that still want explicit rules. | ◇ |
| Profiling and trust scoring | Every dataset gets a 20-section analysis profile: completeness, field statistics, patterns, column semantics, relationship graph, quality metrics, transformation lineage, business rules and source fingerprint. A weighted composite trust KPI rolls up per entity type, per domain and across the estate, recomputed hourly with per-axis breakdown and trend. | Deep per-table quality metrics, root-cause investigation, and a documentation agent. Scored as a monitoring output rather than a catalog profile. | ◈ |
| Sensitive field classification | 129 field classes with deterministic, reproducible verdicts, covering PII, PHI, financial data and secrets. All 18 HIPAA Safe Harbor identifiers are discrete classes with a regulation reference. Source-system fingerprinting identifies where a dataset came from. | Their unstructured product flags sensitive PII inside documents and transcripts using an LLM, along with 15 or more other document checks. Column-level classification of warehouse tables is not what they sell. | ◆ |
| Audit evidence | SHA-256 row chain with Ed25519-signed checkpoints that are themselves chained. Verification returns a three-valued verdict and names the failure: tampering, insertion, deletion or truncation. Try the verifier. | Alerting, incident history and investigation trails. We found no published cryptographic tamper evidence in their public material. | ◆ |
| Agent authorization | Every governed tool call passes a scope ceiling, a consented-tool allowlist, an authority tier and a revocation re-check before dispatch. It fails closed. Delegation is RFC 8693 token exchange with an enforced scope ceiling. | Not part of the product. Their agents run inside their 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 gated, auto-revoking, and it cannot be quietly deleted from the log. | Not described in their public material. | ◆ |
| 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 verifies afterwards. | Their document checks can spot a customer asking to be removed or requesting erasure under GDPR or CCPA. That is detection of a request. The erasure itself is somebody else's job. | ◆ |
| Tokenization and masking | Deterministic, join-preserving, vault-reversible tokens 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. These are features you switch on, not defaults. Detokenization is privileged and every lookup is audited or refused. | Not part of the product. They read your data to score it; they do not transform it. | ◆ |
| MCP and agents | More than 200 MCP tools across Ontology, Auth, Corpus and Lighthouse. Auth issues MCP tool tokens with scope ceilings and meters every call with agent attribution. | Nine named agents, four of them marked coming soon, coordinated by a conversational copilot called AIDA. These are Anomalo's agents doing Anomalo's work. We found no MCP server or tool surface your own agents can call. | ◆ |
| Prompt path | We do not proxy your LLM traffic. We do gate every value that leaves a governed dataset for a prompt, and a PHI dataset refuses an endpoint without a BAA. A classified column with no configured treatment is redacted rather than passed through. | They use LLMs to score your documents and state the data stays in a controlled environment and is not used to train outside models. 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 for Auth, Ontology, Corpus and Lighthouse, with a signed deploy manifest verified by Guardian. Ed25519 audit-signing keys can live in your KMS or HSM. HMAC tokenization keys sit in your environment or derive from your machine key today, not in a KMS. | SaaS, plus a Snowflake Native App on Snowpark Container Services that runs inside your own Snowflake account so monitored tables never leave it. Marketplace listings on Google Cloud and Azure. Strong if your estate is Snowflake-shaped. | ◈ |
| Connector breadth | We scan, profile and classify a live PostgreSQL source in place with no rows leaving it. That is PostgreSQL today, not your whole estate. Snowflake, BigQuery, Databricks, S3 and Salesforce are declared with no handler yet. | Seventeen warehouses and databases, eight catalogs including Collibra, Alation, Atlan and Unity Catalog, eight alerting and ticketing targets, three BI tools, and Airflow and dbt. Not close. | ◇ |
| 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 2018, about $82M raised, strategic money from both Databricks Ventures and Snowflake Ventures, a Gartner Peer Insights Strong Performer badge in December 2025, and 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, and we found no third-party estimate at all. | ◆ |

Three things you get here that you won't get from a data observability platform
Proof that survives an audit
A log that can be silently edited proves nothing. Ours is a hash chain with signed checkpoints, and the verifier says what broke, not just that something did. That is the property EU AI Act Article 12 and HIPAA §164.312(b) reviewers ask about. 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 the next governed tool call is re-checked against current authority and fails closed. A monitoring tool writes you a lovely incident 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, and Anomalo has been at it since 2018. Writing quality rules by hand does not scale past a few hundred tables, and everyone who has tried knows it. Their approach learns each table's normal behaviour and flags the deviation, which is why the logo list has names like Discover and Equifax on it. The distribution is real too: Databricks Ventures and Snowflake Ventures both invested, the Snowflake Native App runs inside the customer's own account, and the integrations page lists more warehouses, catalogs and alerting targets than we will ship for years. Their unstructured product is clever, scoring documents with an LLM and surfacing things like sensitive PII in support transcripts. And they hold SOC 2 Type 2 and HIPAA attestations. We hold neither yet, and a procurement team is right to weigh that.
Here is the push-back. Detection and evidence are different obligations, and only one of them has a regulator attached. Anomalo will tell you a document contains PII. It will not stop an agent from reading that document, it will not tokenize the field first, and 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 and no tool surface a customer's own agent can call, which is a strange gap for a product sold to "the agentic enterprise." If your AI systems are already in production and touching regulated data, the question that bites first is not whether the table looks odd. It is who let the agent in, and how you would prove what it did.
Questions worth asking both of us
These are the questions we would want answered if we were the ones buying. Ask them on every call, ours included.
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 from tampering. Run it against a sample chain at /verify. Anomalo: their public material describes alerts, incidents and investigation history. We found no tamper-evidence mechanism. Ask them to show one.
What happens to a revoked agent mid-session?
DataShield re-checks authority on every governed tool call, so revocation lands on the next call rather than the next token refresh. Anomalo does not sell agent access control, so the honest answer is that this is not their layer. Ask whoever does own it in your stack how long a revoked agent keeps working.
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 still verifies once the subject is gone. Anomalo's unstructured checks can flag a customer asking for erasure inside a transcript, which is genuinely useful as a trigger. Carrying out the erasure, and keeping the audit trail valid afterwards, is not something their public material claims.
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 and no incident management. If pipeline breakage is your problem, buy a monitoring tool. Run us for the governed datasets agents read, where the obligation 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 document your data, and AIDA is described as the conversational layer tying them together. What we could not find is a way for your agent to call their platform as a tool. Ours works the other way round: more than 200 MCP tools, tokens with scope ceilings, per-call metering attributed to the agent. Ask them for the MCP endpoint and 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 published threat model, a verifier anyone can run, and source escrow in design-partner terms so a small vendor is not a single point of failure. Auth is live; Guardian and Lighthouse have been in production since April 2026. Details on the security page.
