AI SQL Rewriting

Blocking a query breaks the application. Rewriting it keeps the application working while eliminating the risk. Safe Boundary can intercept a dangerous SQL statement and modify it on the fly — injecting a LIMIT, adding a WHERE predicate, or stripping a harmful clause — before forwarding a safe version to Postgres.

Rewrites, not just rejections

An unbounded SELECT on a 50-million-row table becomes a bounded query automatically. A DELETE missing a WHERE clause gets a predicate injected or gets blocked based on your policy. The application receives a valid result and never knows a rewrite occurred.

Policy-driven rewrite rules

Rewrite logic is defined in the Safe Boundary control plane, not in application code. Rules are scoped by query pattern, identity, or data classification tag. Changes take effect immediately, with no deployment required on your side.

Keeps AI agents safe without patching the agent

AI-generated SQL is unpredictable by design. Safe Boundary sits between the agent and the database, acting as a semantic guardrail that corrects risky queries without requiring changes to the agent's prompt, code, or model.

Full audit trail for every rewrite

Every rewrite is logged with the original SQL, the rewritten SQL, the matched policy rule, and the identity that issued the query. You have a complete record of what changed and why.

Configure your first rewrite rule — no application code changes required.
