authex Red
Closed engagement. By request only.

Find out if your domain
can still be spoofed.

Authex Red is a closed-access email red team. We test your authentication defences in production and show, with evidence, whether spoofed or unauthenticated mail still reaches your users. Authorized domains only. Paired with Authex Labs.

A clear answer to one question.

Can mail that pretends to come from your domain still land in your users' inboxes? We test it in production and show you what the receiver actually does.

Answer

Yes or no, with proof.

You walk away knowing whether your defences hold in production. The receiver's behaviour is the answer, not a checklist.

Report

Severity-ranked findings.

A written report your board can read and your engineers can action. Each finding is scored, evidenced, and prioritised.

Path to fix

Handoff to Authex Labs.

Every finding maps to fix work in Authex Labs. When the report lands, the next step is already scoped.

Domain owners with
authority to test.

Authex Red is a closed engagement run by the Authex Labs team. There is no public sign-up. Every request is reviewed by hand and bound to a written scope.

By request only

No sign-up. No trial. No download.

Engagements start with a request. We reply within two business days.

Authority verified

We confirm you can authorize the test.

Identity, organization, and domain authority are verified before any work begins.

Scope in writing

Every engagement is fenced.

Domains, recipients, timing, and abort conditions are agreed in writing. Anything outside that scope is out.

Run by Authex Labs

Small team. Manual review. Vetted operators.

No outsourced delivery. No subcontractors. The same team that builds Authex Labs runs the engagement.

Authex Red finds the gap.
Authex Labs closes it.

One team, two services. Findings from Authex Red feed directly into Authex Labs' remediation work. No second vendor. No handoff drift.
