Catch the responses that break policy before your users see them.
ZeroDrift sits between your app and its model, checking every response against your active policies and rewriting the ones that cross a line, in under 30 milliseconds, so your team ships AI assistants without reviewing each output by hand.
Trusted by AI teams at regulated companies
AI responses break policy in ways you cannot predict at design time.
Manual review does not scale
Reviewing AI outputs by hand works for a prototype with ten daily users. At production volume, a single human reviewer cannot check thousands of responses per hour without error rates that defeat the purpose.
Prompt constraints drift under load
System prompt rules hold in testing. Under real user inputs, edge cases accumulate faster than prompt iteration can close them. You discover the gap when a user screenshots the violation, not before.
Compliance cannot tolerate exceptions
In fintech, health, and legal verticals, one non-compliant response reaching a customer triggers regulatory review. The consequence is not a bad review. It is a formal incident with documentation requirements.
Three steps from integration to active compliance.
Route through ZeroDrift
Point your existing model API calls at the ZeroDrift endpoint. One URL change, no SDK required. Requests pass through transparently at the same latency as a direct call.
Define your policies
Write policies in plain language using the policy editor. Specify what responses are prohibited, what replacements to apply, and which audiences trigger stricter rules. Version control included.
Ship with a full audit trail
Every intercept is logged with the original response, the policy triggered, the rewrite applied, and the timestamp. Your compliance team gets a searchable record without manual annotation.
Built for production AI deployments in regulated industries.
Sub-30ms intercept latency
Policy evaluation and rewrite happen in a single async pass. Median p99 latency across deployments is 28 milliseconds, measured at the proxy layer, not the model.
Policy violation catch rate
Across 15 early-access deployments over a 90-day pilot period, 94% of responses that violated active policies were intercepted before reaching an end user.
Unlimited policy versions
Maintain parallel policy sets for different products, audiences, or regulatory environments. Switch between versions without downtime. Roll back to any prior state with one API call.
Drop-in API compatibility
ZeroDrift uses the same request and response schema as the upstream model. No SDK required. Any language, any framework. If you already call the model, you can route through ZeroDrift today.
Results from a 90-day early-access pilot across 15 enterprise deployments.
We were running manual spot checks on 3% of AI outputs before ZeroDrift. That gave us plausible deniability, not actual compliance. Now the intercept log is the audit trail. Our legal team accepted it without additional documentation.
Infrastructure Lead, enterprise fintech AI team, early-access program
The latency concern was the reason we delayed deployment for four months. We assumed any proxy layer would add perceptible delay. At 28ms p99 we cannot measure the difference in our application. That unlocked the project.
