Published · Updated
ZeroDrift offers policy checks, remediation and evidence IDs for teams shipping AI into regulated customer workflows.
What it does
The homepage names SEC, FINRA and HIPAA alongside company policies, with remediation or blocking before output is sent. The developer page says applications can validate outputs, emails and documents and receive violations, citations, rewrites and evidence IDs.
Buyer and task
Teams shipping AI products into regulated customers that need a policy check and evidence trail around generated output.
Workflow boundaries
The checked public pages support the advertised control surface, but do not establish legal compliance, prevention rates or API behavior.
What I would ask
Ask who owns the policy, how citations are evaluated, and whether a blocking decision can be reviewed and overridden.
Why it fits
ZeroDrift’s mechanism is a control point between an AI system and the message it is about to send. The homepage describes an Anchor for the compliance model, a Policy layer for company rules, a Guard for agents and a Command surface for live oversight. The stated decision can be pass, rewrite, block or escalate. The developer page makes that boundary concrete: send content to an enforcement API and receive violations, citations, suggested fixes and evidence IDs in a typed client or plain HTTP response.
That is a sensible architecture for a team whose AI output already faces a regulated-customer or internal-policy review. The buyer can keep the product’s model and workflow while inserting a check before an email, document, browser action or chat response reaches its recipient. The hard questions are policy ownership, rule-pack versioning, latency, false positives and who can review an escalation. A sample verdict on the page is not evidence that the system satisfies SEC, FINRA, HIPAA or any other legal obligation.
The strongest pilot would compare the same small set of known policy cases in pass, rewrite and block states, then inspect the citation and evidence trail. The public material does not establish API behavior or a compliance assessment.
