Red team assessment built around your objectives

A GreySurface red team assessment chases one agreed objective, inside rules you set, to show what a real attacker could reach and whether your team would spot it.

What does a red team assessment cover?

We agree one goal with you, such as reaching customer records, then work towards it the way an outside attacker would.

  • Initial access

    How an attacker gets a first foothold, from the outside in.

    For example, VPN, reused password
  • Social engineering

    Only in scope if you agree it with us in the rules of engagement.

  • Credential access

    How a foothold becomes a valid login, through tokens and reused secrets.

    For example, wiki runbook tokenSee the sample finding
  • Privilege escalation

    How a low-privilege account turns into an administrator.

    For example, prod-deploy role
  • Lateral movement

    How one host opens the next, across accounts, systems and trust.

    For example, jump host, SSH key
  • Detection and response

    Whether your alerts fire, and whether anyone acts in time.

    For example, SIEM, on-call
  • Objective and exfiltration

    How far the agreed goal can be reached, and what leaves with it.

    For example, customer export

What we need from you

  • The objective to pursue
  • Systems in and out of scope
  • Whether social engineering is agreed

On live systems

Live systems by default, inside agreed windows, with a named contact and no destructive actions.

Rules of engagement first, then four steps

Before anything starts we write the objective, the scope and the rules of engagement, so the exercise stays inside limits you set.

  1. Agree the objective

    What the tester does

    We write the goal, the scope and the rules of engagement with you.

    What you learn

    A written record of what is in play and what stays off limits.

  2. Find a way in

    What the tester does

    We study the exposed surface and look for a realistic first foothold.

    What you learn

    Where an outside attacker would start, and how exposed that is.

  3. Reach the objective

    What the tester does

    We escalate, take credentials and move host to host towards the goal.

    What you learn

    How far one foothold spreads before it meets a real control.

  4. Measure what you saw

    What the tester does

    We record each step against your alerts and your team's response.

    What you learn

    Which moves your defenders caught, and which passed unseen.

A tester leads every step. AI speeds up recon, triage and reporting, and a person reviews every finding before it reaches you.

Three paths from a single foothold to the objective

Three samples of how a single foothold becomes a path to the objective. Each begins with one ordinary weakness.

  • Sample

    A reused password opens the door

    A support password from an old breach still opens the VPN. The attacker now holds a trusted session.

  • Sample

    One secret opens the rest

    An admin token left in an internal wiki still works. One copied string reaches the deployment pipeline.

  • Sample

    Quiet steps to the goal

    Keys left in config files lead from one server to the next. No alert fires before the customer database.

Sample finding: one support login to customer records

This sample shows how one stolen support login reaches the customer database, and which steps your team would have seen on the way.

A sample fromCredential access
Sample: Acme CorpMITRE ATT&CK T1078High

From one support login to the customer database

WhereGET /admin/customers/export

Proof of exploit

Token found in a wiki page

GET /wiki/support/runbook
admin_token: [redacted]

Token used on the admin API

GET /admin/customers/export
Host: admin.acme-corp.com
200 OK, customer records
Business risk
An attacker with one support login could reach customer records before anyone noticed.
Fix
Require MFA on support sign-in and scope admin tokens.

Removed: support_signin: password

Added: support_signin: password + mfa

Checked by a tester before it reached the report.

The path taken, what was seen, and each fix

The path we took to the objective, step by step, each step set against whether your team saw it, and the change that would have stopped it.

  2. Fix guidance

  3. Executive briefing

    The path, and what was seen

  4. One retest within 30 days of the report

Built for teams with detection already in place

Teams with a security function already in place, who want their detection and response measured against a real attack path.

  • Mature security teams

    Teams with alerts and a response plan they want tested for real.

  • High-value targets

    Firms where a determined attacker would aim at one clear prize.

  • Boards and risk owners

    Leaders who want a plain account of what an attacker could reach.

When to book it

  • After a penetration testYou have fixed the findings and want to test detection next.
  • Before a board reviewLeadership wants to know what a real attacker could reach.
  • For a customer assurance reviewA major customer asks how you would withstand a real attack.
  • After a major changeA new platform or a merger widens what an attacker could target.
  • To test your blue teamYour detection and response team wants a live exercise to measure against.

Agreeing a red team exercise

We reply to every quote request within one business day, from info@greysurface.com.

Is social engineering part of the test?

Only if you agree it with us. It goes into the written rules of engagement before the exercise starts, or it stays out of scope.

When is a red team the better choice?

When you want detection and response measured. A penetration test covers an agreed set of systems in full; a red team pursues one objective and records whether your team notices.

Will the exercise disrupt our live systems?

We work in your live environment by default, inside agreed windows, with a named contact and no destructive actions.

Who leads the red team?

A tester leads every exercise. AI speeds up recon, triage and reporting, and a person reviews each step and every finding before it reaches you.

What access do you need to start?

The objective to pursue, the systems in and out of scope, and whether social engineering is agreed. We start from an outside position unless you ask otherwise.

Is a retest included?

Yes. One retest checks the reported findings, within 30 days of the report, so you can confirm the path we took is now closed.

How should we prepare for a red team?

Name a single point of contact who knows the exercise is live, agree the window, and decide whether your blue team is told in advance or tested blind.

Would anyone notice? Find out, as agreed.

Tell us the objective you most want tested, even a rough one.
