TapPass vs Prompt Armor.
Prompt Armor protects against prompt injection and jailbreak attacks. TapPass provides end-to-end AI agent governance where injection defence is just one capability of many.

Injection shield vs. governance control plane
Prompt Armor: injection shield
Prompt Armor focuses on jailbreak and injection defence. Effective for that purpose, but it's a single capability in a much larger governance story.
TapPass: complete governance
TapPass sits between agents and LLMs as a complete governance layer. Injection defence is one of many steps. PII, audit, compliance, tool governance, human oversight, all in one pipeline.
Compliance gap
Prompt Armor stops attacks. Your CISO still needs audit trails, PII scanning, and EU AI Act documentation. With TapPass, it's all included.
AI security is more than injection defence.
This comparison is about scope, not quality. Detection tools do detection well. TapPass is the layer that decides what an agent may do, holds the calls that need a person, and leaves a record you can hand to an auditor. If you already run Prompt Armor, TapPass sits in front of it rather than replacing it.
