AI Agent Security

Validate autonomous agent action boundaries before release.

Eresus tests how AI agents can be abused across user intent, tool permissions, memory, retrieval, approval flows, and API actions using realistic scenarios.

Best fit

This engagement creates value fastest for teams like these.

AI product and platform teams

Teams shipping LLM, RAG, MCP, agent, or model-intake workflows into internal or customer-facing environments.

Security leaders expanding into AI

Organizations that already run pentest programs and now need guardrail, prompt, and tool-abuse validation.

Teams that need explainable hardening

Groups that need policy, prompt, MCP, and runtime findings translated into concrete mitigations and release decisions.

Scope

Tool-use and API action boundaries
Memory, retrieval, and context poisoning flows
Approval path, human-in-the-loop, and policy bypass tests
Multi-agent orchestration and permission chains

Risk signals

Agent performs unauthorized action
Data exposure through memory or retrieval
Approval flow bypassed through prompt control
Unexpected production impact through tool chaining

Outcomes

Agent runtime risk map
Tool scope and policy recommendations
Prompt-to-action PoC evidence
Release-readiness security checklist
Engagement model

Not scanner output. Offensive work that produces proof.

01

Scope and objective

We align assets, workflows, user roles, testing windows, and safe operating boundaries before execution starts.

02

Expert validation

Eresus analysts validate exploitability and business impact instead of forwarding automated scanner output.

03

Proof, fix, retest

Each finding ships with evidence, impact, remediation guidance, and retest steps so teams can close risk quickly.

FAQ

The questions buyers want answered early.

What AI surfaces do you test?+
We test prompts, agents, RAG flows, MCP servers, tool use, model intake, and policy boundaries around real user workflows.
Is this just prompt injection testing?+
No. Prompt injection is one layer. We also validate identity, tool permissions, data leakage, model artifacts, and cross-system abuse paths.
Do you translate findings into engineering actions?+
Yes. We map each issue to guardrail changes, prompt updates, identity boundaries, tool scopes, or rollout decisions.

We tie risk to business impact.

Findings do not stop at severity labels. We explain which customer workflow, data class, or operational objective is affected.

Deliverables work for engineers and executives.

Engineering teams get reproducible proof and remediation direction; leadership gets the risk narrative, priority, and closure status.

Next step

Let’s scope this work against the surface that matters most.

Whether this starts as a pilot, a single application, a critical API, an AI agent flow, or a wider program, we start from the highest-impact surface.
