AI-native security review

Find the exposure your AI agents create,
before your customers do.

REDHEXX maps the MCP and agent attack surface in your stack: the unauthenticated tools, over-broad scopes, and injection paths that turn a helpful agent into a liability. Then it shows you what to fix.

Pre-launch. Join the waitlist for early access.

The gap

AI shipped faster than the security model for it

MCP servers and autonomous agents gave models the ability to act. Traditional appsec and pentests weren’t built to reason about agent tool-abuse, so the surface AI adds goes largely unreviewed, right up until enterprise procurement asks about it.

Tools without authorization

MCP servers expose tools an agent can invoke. Many have no per-call authorization, so if the agent asks, the tool runs.

Over-broad scopes

A single tool often grants far more than the task needs: file writes, shell access, internal HTTP. Excess capability becomes leverage.

Injection turns into action

Prompt injection is no longer just wrong text out. With tools attached, an injected instruction becomes a privileged action taken.

How it works

ScanFindingsFix guidance

A focused review of the AI-added attack surface, not a generic pentest with an AI label.

01 — SCAN

Enumerate the real surface

We enumerate your MCP servers and agent tool surface from configuration and a scoped test environment, then probe authorization boundaries the way an attacker-steered agent would. No standing production access required.

$ redhexx discover mcp://demo.local
→ 14 tools · 6 agents · 22 downstream calls

RANKED FINDINGSsample

excess capability · read_file MEDIUM
02 — FINDINGS

Ranked exposures, with evidence

Each exposure is written up with a severity, the context it is reachable from, evidence, and a plain explanation of why it matters, ranked so you know what to address first.

03 — FIX GUIDANCE

Remediation that fits your system

Every finding ships with concrete remediation mapped to your intended trust boundary: scope reductions, authorization checks, and guardrails that fit how your system is actually built.

REMEDIATIONsample
Scope fetch_invoice to read-only, single tenant
Add per-call authorization on export_report
Gate planner_agent tool calls behind human review
Drop read_file from the agent’s tool set

A narrow surface, reviewed properly.

The part traditional appsec still skips, read the way an attacker-steered agent would actually use it.

Why REDHEXX

Credibility from substance, not logos

We’re early and we’ll tell you so. What we bring today is a specific, technical read of a surface most reviews still skip.

◢ INDEPENDENT

No platform to sell you, no vendor to defend. The findings are about your exposure, not our roadmap.

◢ TECHNICAL

Grounded in how MCP and agent frameworks actually work: protocol behavior, tool schemas, and the trust assumptions between them.

◢ HONEST

We only claim what we can show. Every finding is evidence-backed, and where something is a sample or a limitation, we say so.

Every finding, traced end to end

From the first request to a captured proof-of-concept, a finding shows exactly how it was reached, not just that it exists.

FAQ

Questions worth asking first

Is this a product or a service?

Right now, a hands-on review performed for you. The open-source scanner and self-serve platform come later on the roadmap.

How is this different from a pentest?

Traditional pentests rarely reason about prompt-injection-to-tool-abuse or agent privilege chains. REDHEXX focuses specifically on the attack surface that MCP servers and agents add.

Do you need production access?

No. We work from your MCP and agent configuration plus a scoped test environment. We don’t need standing access to production data.

What do I actually get?

A ranked findings report: each exposure with its severity, why it matters, and concrete remediation mapped to your intended trust boundary.

Will this help with enterprise security review?

That’s the point. The goal is to surface and close gaps in your AI attack surface before a customer’s procurement or security team finds them.

Are you available right now?

We’re pre-launch and onboarding a small number of early design partners. Join the waitlist and we’ll reach out as we open access.

Founder

Why I’m building REDHEXX

I kept watching teams bolt tools onto language models (MCP servers, agent frameworks, internal actions) and move fast, because it works. What I didn’t see was anyone checking what those agents could actually reach when someone pointed them the wrong way.

The security tooling we have was built for a world where software does what it’s told. Agents do what they’re convinced to do, and the blast radius is whatever tools you handed them. That’s a different problem, and it deserves a review that takes it seriously.

REDHEXX is my attempt to build that review: narrow, technical, and honest about where it is today. If that’s a gap you feel too, I’d like to hear from you.
