Your agentic CISO,
always on.
dFence is a runtime AI guardrails platform for agentic applications. It observes every request, understands policy defiance, and intervenes with the right action when prompts, tools, data, or agent behavior become unsafe.

Protection that understands, then acts.
Intent-based access
Allow tools and MCP calls only when the live action matches the agent's declared happy path.

Observe. Understand. Intervene.
dFence creates a closed decision loop around every agent request, from raw telemetry to autonomous action.
01ObserveEvery request, response, data source, and tool call
→ 02UnderstandIntent, context, policy defiance, and business risk
→ 03InterveneBlock, redact, constrain, alert, or allow autonomously
Intent-based access management
Access control for what the agent is trying to do.
Traditional access control asks whether a credential is allowed to call a tool. Agentic systems need one more question: does this specific action match the intended purpose of the interaction? dFence evaluates intent before sensitive tool and MCP calls, so an agent cannot use valid access for the wrong reason.
Declared happy path
Define what the agent is supposed to do in a workflow, including allowed goals, data boundaries, tools, and approval points.
Intent check
dFence compares the live request, context, tool choice, MCP call, and action parameters against the expected intent.
Trust-aware decision
Trusted low-risk calls can proceed. Untrusted, sensitive, or mismatched actions are blocked, constrained, redacted, or sent for approval.
Application Support agent Export all customer records

dFence decision Blocked: intent mismatch
Tool call stopped and audit event created dFence does not rely only on static scopes. It enforces the reason behind the action.
Minimal latency, complete coverage
Get peace of mind with dFence.
Use more than 100 checks with policies deployed as enforcers or observers based on criticality—avoiding heavy, one-size-fits-all guardrails.
