Test prompt security by impact, not by response filters alone.
Eresus measures how untrusted inputs such as user messages, email, documents, web pages, RAG sources, and MCP tool descriptions can change LLM behavior.
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
Risk signals
Outcomes
A practical test flow that turns input threats into business impact.
Problem
We map which untrusted content the LLM reads and which actions it can reach.
Attack scenario
We test visible user messages and hidden document instructions separately.
Proof
Successful bypasses are shown through responses, tool calls, accessed data, and logs.
Delivery
Fixes are described across system prompts, data separation, tool scopes, and approval gates.
The questions buyers want answered early.
What AI surfaces do you test?+
Is this just prompt injection testing?+
Do you translate findings into engineering actions?+
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.

Authentication Bypass via skipAuth Configuration Grants Full Admin Access in MCPHub
When skipAuth is enabled, MCPHub bypasses both authentication and admin authorization checks, allowing any unauthenticated user to access privileged API functionality.
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.
