Secure the agent, contain the blast radius.
AI agents are a new, fast-moving attack surface: they hold credentials, call tools, and act at machine speed. B5 Secure puts every agent inside the Never Trust pipeline — a scoped, revocable identity whose every action is signed, least-privileged, logged, and instantly killable — so a compromised or confused agent can do little, and only briefly.
The challenge
Agentic systems introduce risks classic apps don’t have: prompt injection that hijacks the agent’s intent, tool and function abuse, excessive agency (an agent with far more access than any single task needs), and the confused-deputy problem — a trusted agent tricked into acting for an attacker. A broadly-credentialed agent that goes wrong can scrape records or move money before a human notices.
The Never Trust answer
Treat the agent as exactly what it is: a non-human identity that must earn every action. In B5 Secure an agent is a first-class identity in the same pipeline as humans — least privilege scoped to the action and record, every call signed and replay-proof, and revocation that reaches live sessions in seconds. Autonomy never means unaccountable, and never means unbounded.
Five controls that bound an agent
Scoped, least-privilege identity
Each agent gets its own identity bound to specific operations and records — and, where needed, to a single value such as one account id. Excessive agency is designed out: the agent can only touch what its task requires.
Signed, replay-proof actions
Every tool call the agent makes carries a keyed signature with timestamp expiry and nonce, optionally bound to a specific record. A hijacked or replayed agent action is rejected, not executed.
Prompt-injection & tool-abuse defense
The agent’s authority lives in the pipeline, not the prompt. Even if injected text tells the agent to act, the action still has to pass authentication, authorization, and the firewall — so a hijacked intent can’t exceed the agent’s granted scope.
Instant kill-switch (CAE)
Suspend an agent — or a single operation on a single entity — the moment a signal fires, and Continuous Access Evaluation revokes its active sessions in near-real-time. The blast radius is bounded in time as well as scope.
Isolation & full audit
Confidential computing isolates sensitive inference; every agent decision is logged with inputs, identity, model version, and outcome — so an incident is fully reconstructable and a confused deputy is caught.
Let agents act — safely.
Give every AI agent a bounded, revocable identity inside the same pipeline that secures $15B+ in custody. Pair it with governance for the full picture.
