PII proxy scope
Mostly request or response text scanning and masking.
Comparison · PII proxy vs evidence gateway
A PII proxy redacts text. Talon proves governance.
A PII proxy can be a useful narrow control. Talon’s 2.0 wedge is wider and more defensible: EU-sovereign egress control, pre-spend cost policy, tool governance, provider routing, and signed evidence for auditor review.

Core difference
Redaction is not a governance record.
Talon 2.0 should not be described as a better PII proxy. The sharper claim is that Talon turns AI traffic into signed evidence: who called, what data was detected, which policy ran, where traffic was allowed to go, what it cost, and whether the record still verifies.

When to use each
Pick a PII proxy only when the problem is only redaction.
Use a PII proxy if the buyer only needs to mask sensitive strings. Use Talon when the buyer must prove governed AI traffic for a customer, DPO, security, board, or auditor review.
Use Talon when the buyer asks:
- What data left?
- Where did it go?
- Which policy allowed it?
- Was spend capped before the call?
- Which tools were exposed?
- Can you verify the record?Practical test
Run one PII-bearing request through Talon.
Send a request with test PII, inspect the decision, export the evidence, and verify the signature.
