The LLM Is Not the Final Authority: Building Trust Infrastructure for AI Agents

Short summary

Pramagent is an open-source framework treating LLMs as untrusted components needing defense-in-depth security. Its 7-layer architecture (compliance, isolation, safety rules, output judging, HITL approval, audit trails) blocks attacks before models see them and records tamper-evident hash-chain traces. PII is scrubbed before provider calls, injection attacks are deterministically blocked, and consequential actions require explicit human approval.

• •Seven-layer defense-in-depth architecture handles compliance, isolation, input/output safety, reliability, provider abstraction, and human approval gates
• •PII scrubbing, injection blocking, and output validation happen outside the model—deterministic and tamper-evident
• •Every call produces SHA-256 hash-chain audit traces proving what happened and in what order
