Show me what the AI did.

Every prompt blocked, every redaction recorded, every decision on a tamper-evident record. The answer to any security question is already written down, in a chain no one can edit.

What you get asked

And the record that answers it.

Who sent patient data to a model last week?

Tower scans every prompt before it reaches the model. Personal data is replaced with coded stand-ins such as PERSON_1. 79 personal-data and credential types are detected, including all major credential formats. The record shows what was found, what replaced it, and who sent it.

Can an attacker talk the model out of its rules?

Jailbreak and prompt-injection attempts are intercepted by policy JAILBREAK-001, run on the full assembled prompt before the model is called. A blocked prompt never opens a stream to the model. The refusal is a tamper-evident record, the same as any other decision.

Can anyone edit the log?

No. Every record carries a SHA-256 hash, chained by the previous record’s hash and anchored outside the database, so any change shows. Database triggers refuse updates and deletes. Retention is 10 years.

Common questions

Answered straight.

Does Tower intercept every AI call, or only calls from approved apps?
Every call: from the AI Console, from SDK clients, from agent frameworks, and from any app pointed at Tower’s Anthropic-compatible endpoint. Nothing bypasses the policy layer.
What happens if a prompt contains a credential or API key?
Tower detects credential types including Stripe live keys, Google API keys, private keys, JWTs, and bearer tokens. The credential is replaced with a coded stand-in before the model sees it.
How do I prove to an auditor that a record was not altered?
Each record carries a SHA-256 hash of its content, chained by the previous record’s hash and anchored outside the database. Records are linked so any change shows. The Proof Pack provides tamper-evident evidence ready for export.
Can we limit which models different teams can access?
Yes. Models are enabled per organisation, team, or group. Budget limits can be set per user, team, group, organisation, or client app, on daily, weekly, or monthly limits.
Does this slow down AI calls?
You choose how deep the checking goes for each use case. Blocked calls never open a stream to the model, so there is no model latency cost for refused requests.
