Safe Boundary PostgreSQL AI firewall
Let AI query your databases without surrendering control
Spectral Core’s
AI database firewall
Safe Boundary is Spectral Core’s AI database firewall. It ensures AI can never execute queries outside the boundaries you define, regardless of query complexity, structure, or intent.
Queries are generated dynamically
AI queries evolve in real time — Safe Boundary inspects every request and ensures it never breaks the rules you define.
Intent is opaque
We don’t rely on guessing intent. Every query is validated strictly against your policies, regardless of how it’s phrased.
Mistakes scale instantly
A single mistake in an AI system can propagate across millions of queries. Safe Boundary stops issues at the first attempt.
One bad query can corrupt data
A single malformed query can compromise data integrity. We block it before it ever reaches your database.
Schema-aware enforcement
Understands your database structure and prevents invalid or dangerous operations before execution.
AI is unpredictable
AI models aren’t deterministic — your safeguards should be. Safe Boundary brings consistent, reliable control.
How Safe Boundary Works
Safe Boundary performs semantic SQL inspection on every request
Real-time SQL inspection
Safe Boundary performs semantic SQL inspection on every request — not simple pattern matching, but deterministic enforcement that understands query structure and intent.
Complex queries are understood, not guessed at
Nested logic and edge cases are handled correctly
Enforcement is deterministic and explainable
Query-level enforcement
Policies enforced at the SQL layer
Block destructive operations
Restrict access to sensitive tables or columns
Prevent unintended writes or schema changes
If a query isn’t allowed, it doesn’t run. Period.
Safe Boundary sits between AI and your database
Every query passes through a super-fast proxy that performs deep SQL analysis in real time. Queries that attempt to write to your databases are blocked before they ever reach the database, no matter how complex or nested they are.
Safe Boundary is designed to run in the critical path without becoming a bottleneck.
Microsecond-level overhead
Adds virtually no latency to query execution — enforcement happens in microseconds, not milliseconds.
No database extensions needed
Works with your existing database — no plugins, no engine changes, and no vendor lock-in.
No agents or invasive changes
No sidecars, no agents, and no schema rewrites. Just place it in front of your database and enforce policy.
Transparent proxy architecture
Runs as a transparent layer between your application and database, with predictable behavior and minimal operational overhead.
It’s as operationally boring as a connection pooler. That’s exactly the point.
Automatic PII Protection
Safe Boundary goes beyond blocking queries. Using Spectral Core’s static analysis engine, Safe Boundary can automatically mask PII data through real-time query rewriting. Sensitive data is protected before it ever leaves the database.
Plug-and-Play by Design
Safe Boundary is built to be easy to adopt:
Drop-in deployment
Works with existing PostgreSQL databases today
Exposes a read-only PostgreSQL port where it intercepts your queries and data
Turn it on, define boundaries, and let AI work safely.
Who Safe Boundary is For
Safe Boundary is Spectral Core’s AI database firewall. It ensures AI can never execute queries outside the boundaries you define, regardless of query complexity, structure, or intent.
Safe Boundary is ideal for teams that:
Connect AI systems directly to databases
Handle sensitive or regulated data
Use MCP servers or similar architectures
Want AI productivity without operational risk
With Safe Boundary:
AI cannot issue unsafe or destructive SQL
Performance remains uncompromised
Sensitive data stays protected
You regain control without slowing innovation
Safely unleash AI on your data. No need to trust it.
