AI agent security questions, answered plainly.

AI agent security is the practice of protecting autonomous AI agents from being hijacked and stopping them from doing damage when they act with real credentials. Because agents read untrusted text (web pages, emails, documents, tool outputs) and then call tools, move data, and take actions, they introduce a new attack surface: prompt injection, over-permissioned access, and missing audit trails. Agentshield is the runtime firewall for AI agents that addresses all of it in one control plane: it blocks prompt injection, enforces exactly which tools and data each agent may touch, monitors every action in real time, and writes an immutable audit trail.

For the common path, inspection is millisecond-class and runs inline so the agent waits only a moment before its action is cleared, blocked, or held. For latency-sensitive flows you can run Agentshield in observe-only mode, where it monitors and logs every action without blocking, then switch specific high-risk tools to enforce mode once you trust the policy. You decide which actions are inspected inline and which are watched asynchronously.

No, when policy is scoped to what each agent actually needs. Agentshield is tunable and starts in observe-only mode so you can see what would be blocked before anything is. Decisions are policy-scoped rather than a blanket filter, so a clean, in-policy action sails through. The Clean request scenario in the demo shows a legitimate action being cleared, which is the point: Agentshield governs traffic, it does not just block everything.

Agentshield is stack-neutral. It drops in front of OpenAI, Anthropic, LangChain, CrewAI, MCP servers, and custom agents as a control plane, so there is no framework rewrite. It sits in the request and action path rather than replacing your agent framework, which means you keep the stack you already built and add firewall, permissions, monitoring, and audit in front of it.

No. Agentshield never trains on your data, ours or anyone else's. It inspects agent traffic to enforce policy; it does not collect your content to build models. Data is encrypted in transit and at rest, access is least-privilege, and you control retention and deletion. You stay in control of every action. See the security page for full data-handling detail.

No. Agentshield is four controls in one plane, not a single guardrail. It combines a prompt-injection firewall, tool and data permissions, real-time monitoring, and an immutable audit trail, so you get the firewall plus least-privilege plus observability plus the audit evidence without stitching together three vendors. It is the control layer in front of your agent, not a single point tool you bolt on.

Yes. The human-approval gate, shown in the demo, holds high-risk actions such as refunds, deletes, mass sends, or data exports for a person to approve or deny before they execute. You set which tools and thresholds require a human, and the agent waits until someone signs off. Every approval is written to the audit trail with who approved and when.

Yes. Agentshield's policy controls and immutable audit trail map directly to the evidence that frameworks and procurement now ask for. The OWASP Top 10 for LLM Applications is the canonical risk taxonomy, and the EU AI Act's high-risk obligations require records of what automated systems did. The audit trail is exactly the artifact auditors and enterprise buyers request, and it exports to your SIEM.

Yes, on higher tiers. On-prem, private cloud, and VPC deployments are available on Scale and Enterprise plans for teams with data-residency or isolation requirements. Reach out through the contact page and a security engineer will scope the deployment with you.

Agentshield has transparent, self-serve pricing with real prices on the pricing page, starting at $49 per month on the Developer plan, $199 per month on Team (the most popular), and $749 per month on Scale, with Enterprise priced by volume. There is no contact-sales wall to learn the cost, which is part of the wedge: you should not have to book a call to find out what an agent security tool costs.
