Red Teaming

How far would a real attacker get? The more important question than 'where are the gaps'.

Module-based pentests find individual weaknesses. Red Teaming chains them together — recon, phishing, physical access, Active Directory — up to one defined objective: domain admin, customer database, production control. Covert, unscheduled, tested against your actual blue team.

Avg. active attack duration to reach objective 3–8 days Full engagement incl. scoping & report: 4–8 weeks
CRTO & CRTP certified team Objective-based, not a checklist scan Covert, usually only C-level is informed

The difference

Why isn't a module-based pentest alone enough?

Isolated vs. chained

A single finding looks harmless — a chain doesn't

An exposed account, an unguarded door, one phishing email: each often rated 'medium' on its own. Only the chain — phishing, stolen credentials, physical access, lateral movement — reveals the real business impact, the same path a real attacker would take.

Announced vs. covert

Does your security team even know when you're being tested?

Module-based pentests are usually scheduled and known in advance. Red Teaming additionally tests whether your SOC or blue team notices a real, unannounced attack at all — and how fast they respond.

Breadth vs. depth

Testing everything a little, or pursuing one goal for real?

Modules systematically cover the breadth of your attack surface. Red Teaming pursues one defined objective using every realistically available means — exactly like a real, motivated attacker would.

Positioning

Module-based pentest or red teaming — what fits you?

Aspect Module-based pentest Red teaming
Guiding question Where are the vulnerabilities? How far does an attacker get?
Scope Single system / single vector Entire organization, one defined objective
Awareness Known and scheduled Covert, usually only C-level informed
Tests detection & response Not the focus A core part of the engagement
Best suited for Compliance evidence, annual cadence Security maturity beyond compliance
Physical access Only if booked separately Included in the attack chain by default

The two aren't mutually exclusive: most of our red team clients have already run module-based pentests with us or other providers and now want to know whether their detection actually holds up in a real incident.

Attack surface

The routes we attack through

A red team takes whichever route works, and it is rarely the most elegant one. So we plan every engagement across several vectors at once and switch as soon as one stops leading anywhere. Which of them are used is set in the scope.

People Physical Network & Active Directory Identity & cloud Objective
Four routes, one objective
  1. People

    Phishing, vishing, pretexting

    Targeted emails to a single department, calls in the name of IT support, prepared USB sticks or a QR code on the notice board. In most engagements this is the fastest way to a first foothold.

    Tests: awareness, reporting behaviour, MFA rollout
  2. Physical

    Tailgating, lockpicking, RFID cloning

    We follow someone in through the side entrance, copy an access card in passing, or leave a device in a meeting room that calls home. The physical pentest page explains how this works in detail.

    Tests: access control, reception, how staff treat strangers Physical pentest
  3. Network & Active Directory

    Exposed services, service accounts, lateral movement

    Forgotten VPN portals, weak passwords on service accounts, group permissions that reach too far. Inside the network, the path to the objective almost always runs through Active Directory.

    Tests: hardening, segmentation, AD tiering Active Directory pentest
  4. Identity & cloud

    Microsoft 365, Entra ID, token theft

    A captured password is usually a cloud login these days. We check conditional access rules, MFA exceptions, legacy protocols, and which further doors a compromised mailbox opens.

    Tests: conditional access, MFA gaps, cloud logging

Formats

Not every red team has to start covertly from the outside

The classic approach starts from outside with no prior knowledge. It is the most realistic option, and the most expensive one. Depending on maturity and budget there are three further variants we run regularly.

The standard

Full-scope red team

From internet research to the objective, with no prior knowledge and no announcement. Measures the whole system including detection and response.

Who it is for

Organisations with their own SOC or an MDR provider who want to know whether it holds up in a real incident.

The quick start

Assumed breach

We start with what an attacker would have after successful phishing: a regular employee account and a laptop on the network. This skips the initial access phase and puts the budget into the path to the objective.

Who it is for

A first test of internal detection, or when phishing has already been tested separately.

Together instead of covert

Purple team

Attack and defence sit in the same room. We run one technique after another, your team checks live whether and where alerts fire, and detection is tuned on the spot.

Who it is for

Teams building a SIEM, or closing the gaps found by a red team in a structured way.

Regulatory

TIBER-EU-aligned red teaming

For financial entities heading towards a TLPT under DORA: red teaming along the TIBER-EU phases, with a threat intelligence lead-in, a control team on your side and matching documentation. Processes and roles get a full rehearsal before the mandatory test.

DORA page
Who it is for

Banks, insurers and payment providers that the supervisor has selected for a TLPT, or that expect to be.

Rules of engagement

What we may do, what we may not, and who can pull the plug

A red team uses the methods of real attackers, but not their freedoms. Before the first email goes out there is a set of rules both sides sign. These points are part of every engagement we run:

  1. Letter of authorization

    Names the client, scope, time window and the authorised operators. On every physical job our people carry it with them, together with a phone number where a contact can confirm the assignment.

  2. White cell

    One or two people on your side who are in the know and reachable throughout the engagement. They know what we are doing, can escalate, and decide in doubt whether an alert is real or ours.

  3. Stop criteria

    Either side can stop at any time. We pause on our own as soon as we find traces of a real attacker, would put a production process at risk, or people could get hurt.

  4. No destructive actions

    No deleting, no encrypting, no denial of service, no changes to production data. Where a real attacker would deploy ransomware, we drop a marker file and document the access.

  5. Handling of data

    We do not copy out real customer or personnel data. Access is proven through screenshots, hash values or test records placed in advance. Captured credentials are stored encrypted and deleted after the project.

  6. Off-limits

    Employees' private devices and home connections, third-party systems outside the scope, and safety-relevant OT controls are excluded unless you explicitly release them.

  7. Logging

    Every action is recorded with timestamp, source and target. That lets your SOC map every alert to a step afterwards and tell our activity apart from a real one.

  8. Deconfliction

    If your SOC reports an incident during the engagement, the white cell checks with us within minutes whether it came from us. If it did not, we pause and you treat it as a real incident.

The other side

What your blue team ends up holding

The live simulation above shows the attack from our side. For you, the mirror question matters: which of it did your detection see, and when? That is why the report sets each attack phase against what actually reached the SOC.

Phase Our action What the SOC saw Verdict
Recon OSINT, passive reconnaissance, external port scan Nothing. With passive reconnaissance that is expected. Neutral
Initial access Phishing to six employees, two sets of credentials captured One person reported the email after 40 minutes. The ticket saw no follow-up. Detected, no response
Physical foothold Tailgating, rogue device in a meeting room Nothing. The device ran until the debrief. Not detected
Internal access Network scan, Kerberoasting SIEM alert on unusual Kerberos requests, closed as a false positive Detected, misjudged
Privilege escalation Lateral movement to three servers EDR blocked one tool. The operator switched methods, no further alert. Partially detected
Objective Domain admin, marker file placed Only at the debrief Not detected

Simplified, anonymised example based on typical results. This comparison is where the real recommendations come from. Next to the patch, the list then holds items like “take alert X seriously” or “change the visitor process”.

Why Access Granted

Genuine red team experience, not a bolted-on add-on

Physical-to-cyber from a single provider

Most red team providers stay purely digital — phishing and network access. With over 100 physical pentests delivered, we bring real physical access in as a full part of the attack chain: from tailgating to a rogue device in the server room.

CRTO & CRTP certified

Objective-based red teaming and Active Directory attack chains are their own discipline with their own certifications — not simply 'more pentesting'.

An investigator's perspective

Our founder's background is in cybercrime investigation at the German police — attacker psychology and offender profiling feed directly into how we plan an attack.

Context

Where red teaming shows up in regulation and standards

Red teaming is not mandatory for everyone anywhere. In several places, though, it is the way to actually prove the effectiveness review that is required.

DORA

Art. 26 obliges financial entities designated by the supervisor to run a threat-led penetration test under TIBER-EU every three years. Everyone else falls under Art. 25 with regular testing, for which red teaming is the most demanding form.

DORA page

NIS2

Art. 21 requires policies and procedures to assess the effectiveness of risk management measures. A red team delivers exactly that assessment, including the human factor and detection.

NIS2 page

ISO 27001

Clause 9 of the standard requires information security to be monitored, measured and evaluated. In an audit, a red team report is solid evidence that effectiveness was reviewed independently.

ISO 27001 page

KRITIS / BSIG

Operators of critical infrastructure prove every two years that their measures reflect the state of the art. Red teaming does not replace that review, but adds the attacker's view of the whole system.

KRITIS page
FAQ

Red teaming — your questions

That's up to you. By default, only a very small circle (usually C-level and one 'white cell' contact) is informed — that's exactly what makes the test meaningful for evaluating your detection and response. Partially announced variants are possible on request.

Detection is itself a metric, not a reason to stop the test. We escalate in a controlled way according to pre-defined rules and report detection as a standalone result.

A pentest systematically covers the breadth of a defined system or vector. Red teaming pursues one concrete objective using every realistically available means — technical, human, and physical access combined — and additionally tests detection and response.

Module-based pentests are the foundation — they surface individual gaps. Red teaming is the logical next step for organizations that have already reached a certain level of security maturity and want to know whether it actually holds in a real incident.

Physical access isn't an add-on for us — it's a core part of the attack chain whenever it fits the scope. With over 100 physical pentests delivered, we bring specialized experience: from tailgating and lockpicking to RFID cloning and rogue devices. Many red team providers stay purely digital; that's exactly the gap we close.

The risk is much lower than with a broad vulnerability scan, because we go after specific targets instead of scanning everything. Destructive actions are excluded, production-critical systems are handled separately in scoping, and the white cell can stop at any time.

In an assumed breach we start already inside the network, with the rights of a regular employee. That skips the initial access phase, often the most time-consuming one, and focuses the budget on how far an attacker would get after successful phishing. Useful as a first test of internal detection, or when phishing has already been tested separately.

A joint debrief with your internal security team: we walk through the attack chain step by step, show what was detected and what wasn't, and work together on concrete detection and response improvements.

Together, during scoping — usually one concrete 'crown jewel': domain admin, a specific database, access to a production control system. The objective is based on your real threat model, not a generic template.

Before every engagement we issue a letter of authorization with a clearly defined scope, authorized contacts, and emergency contacts. Our operators carry this document with them throughout the engagement.

Once basic security measures — ideally including initial module-based pentests — are already in place. Red teaming tests the effectiveness of your overall system, which only makes sense once there's something to detect and stop in the first place.

Credentials are stored encrypted, used only for the engagement, and verifiably deleted afterwards. We do not copy out real customer or personnel data. Access is proven with screenshots, hash values or test data placed in advance.

A TLPT is a red team with a fixed regulatory frame: a mandatory threat intelligence phase, a control team on the institution's side, involvement of the supervisor, and documentation under TIBER-EU. It is only mandatory for financial entities the supervisor selects. For everyone else, a red team without that superstructure is the right format.

Terms

In short

The terms from the simulation and the report, without the jargon.

OSINT
Open source intelligence: everything about you that can be pieced together from public sources. Website, job ads, LinkedIn profiles, a photo of a company badge on Instagram.
Initial access
The first access to a system or account inside the organisation, usually through phishing, an exposed portal or physical entry.
Foothold
A persistent access that survives a reboot or password change. Work continues from here.
C2 (command & control)
The link between a compromised machine and the attacker's infrastructure that carries commands. Disguised as normal web traffic.
Lateral movement
Moving from one system to the next, one step closer to the objective each time.
Kerberoasting
An Active Directory attack that requests service tickets and cracks them offline. Works when service accounts have weak passwords.
Rogue device
A small computer we plug into the network inside the building that opens an access path for us from outside.
Tailgating
Walking through a door behind an authorised person without a card of your own. Works alarmingly often with a coffee cup and a phone in hand.
White cell
The few people on the client side who know about the engagement and act as contacts and emergency brake.
TTPs
Tactics, techniques and procedures: an attacker's ways of working, described in a standard form in the MITRE ATT&CK framework.
Crown jewels
The systems or data whose loss would hurt the organisation most. They are the engagement's objective.
Purple team
Red and blue together: attackers and defenders work openly side by side to improve detection and response.
