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.

Once AI has database access:

  • Queries are generated dynamically
  • Intent is opaque
  • Mistakes scale instantly
  • One bad query can corrupt data, expose PII, or take systems down
  • AI is unpredictable, you never know who and when might trigger destructive actions with it, even with best intentions

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.

Latency impact is negligible, measured in microseconds.
Yes, there’s an extra hop (just like with a connection pooler) and no one complains about those.

How Safe Boundary Works

Real-time SQL inspection

Safe Boundary performs full semantic SQL analysis on every query, not simple pattern matching.

  • Complex queries are understood, not guessed at
  • Nested logic and edge cases are handled correctly
  • Enforcement is deterministic and explainable

Query-level enforcement

Policies are enforced at the SQL level:

  • 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.

Built for Performance

Safe Boundary is designed to run in the critical path without becoming a bottleneck.

  • Microsecond-level overhead
  • No database extensions needed
  • No agents or invasive changes
  • Transparent proxy architecture

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.

Safe Boundary is ideal for teams that:

  • Connect AI systems directly to databases
  • Use MCP servers or similar architectures
  • Handle sensitive or regulated data
  • Want AI productivity without operational risk

With Safe Boundary:

  • AI cannot issue unsafe or destructive SQL
  • Sensitive data stays protected
  • Performance remains uncompromised
  • You regain control without slowing innovation

Safely unleash AI on your data. No need to trust it.
