Red Team Testing

Red Teaming Services

Evalian’s Red Teaming service simulates realistic, goal‑driven attacks against your people, processes and technology to understand whether your defences, detection, containment and response stand up to a cyber attack.

Our Red Teaming assessment targets the areas attackers exploit most: your external attack surface, identity and access controls, and internal response once access is gained. It provides a realistic cyber resilience assessment in weeks rather than months.

Our UK-based team of CREST-certified security consultants deliver focused, high-value red team engagements designed for organisations seeking to improve their security posture without the cost and complexity of a full-scale red team exercise.

Red Teaming Benefits

A Red Team Assessment is ideal for organisations that already conduct regular penetration testing and now want to move beyond vulnerability-based testing to capability-based testing.

Realistic Threat Simulation: Test your defences against real-world adversary tactics.
Detection & Response Validation: Measure how quickly and effectively your security team can detect and respond.
Cost-Effective Red Teaming: Advanced testing without the resource demands of full red team exercises.
Rapid Engagement: Results delivered faster than traditional red teaming.
Actionable Insights: Clear recommendations to strengthen security posture.

Red Teaming & How It Differs To A Penetration Test

Red Teaming is a goal-driven cyber security assessment designed to test your organisation’s ability to prevent, detect and respond to sophisticated attacks.

Whereas penetration testing focuses on identifying and reporting technical vulnerabilities, Red Team Testing focuses on achieving a defined objective, such as accessing sensitive data, compromising critical systems, or bypassing detection controls.

This approach provides a realistic measure of security maturity, across technology, processes and people.

When To Consider A Red Team Security Assessment

Red Team Assessments are suited to organisations that:

Perform regular penetration testing and want to validate true resilience.
Operate security monitoring or SOC services and want to test their detection capability.
Use MFA, EDR, SIEM, XDR or other security tooling and require independent effectiveness validation.
Wish to understand how attackers could move internally, escalate privileges or exfiltrate data.
Need assurance ahead of regulation, audit or board-level accountability.

Our Red Teaming Approach

Evalian’s Red Team methodology is built to mimic how modern attackers operate, not just which vulnerabilities they exploit, but how they prioritise targets, adapt to defensive measures, and pivot when opportunities appear.

The engagement is structured into two core phases: External (gaining access) and Internal (demonstrating impact), and is underpinned by iterative feedback loops that allow the exercise to evolve in real time, mirroring how an actual adversary would behave.

External Phase: Finding A Way In

The goal of this phase is to establish Initial Access, just as a motivated attacker would.

Component	Description	Objective
Digital Perimeter Assessment	Review of externally accessible infrastructure and services	Identify viable attack vectors
Intelligence Harvesting	Collection of exposed credentials, employee data and open-source intelligence	Reduce intelligence exposure attackers rely on
Connectivity Evaluation	Analysis of remote access configurations, cloud services and authentication flows	Validate identity and access security controls
Adversary-in-the-Middle (AiTM) Phishing	Sophisticated phishing designed to bypass MFA	Assess user susceptibility and email defence performance

Internal Phase: Intrusion Scenario

This phase reflects how quickly and effectively an organisation can respond to a real intrusion scenario.

Component	Focus Area
Privilege Escalation	Identifying routes to higher-value permissions
Lateral Movement	Testing segmentation, identity boundaries and monitoring gaps
Data Discovery	Determining how easily sensitive assets can be located
Data Exfiltration Testing	Assessing monitoring, alerting and incident response readiness
Command-and-Control Simulation	Testing SOC awareness, telemetry visibility and response times

Red Teaming FAQs

What is the difference between Red Teaming and Penetration Testing?

Penetration testing focuses on identifying and reporting vulnerabilities across systems, applications or networks. The aim is to find as many weaknesses as possible and provide remediation guidance.

Red Teaming, by contrast, is objective-driven. The Red Team attempts to achieve a specific goal, such as accessing sensitive information or bypassing detection, using tactics that mirror real threat actors. The purpose is to assess resilience, not just vulnerability exposure.

Is Red Teaming only suitable for large organisations?

While Red Teaming is often associated with large or regulated organisations, it is equally valuable for midsize businesses that:

Already conduct regular penetration testing
Operate a Security Operations Centre (SOC) or outsourced detection service
Need to validate real-world resilience rather than theoretical risk

Our Red Team Essentials service is specifically designed to deliver this capability without the resource overhead of a full-scale red team engagement.

What objectives can a Red Team Assessment test?

Objectives are tailored to each organisation. Typical outcomes include:

Gaining initial access to internal systems
Achieving privileged or domain-level control
Accessing confidential, financial, personal or operational data
Testing the ability to detect and respond to malicious behaviour

The chosen objective aligns with business impact, ensuring the engagement measures outcomes that matter.

Will our security team know the test is happening?

This depends on the purpose of the engagement:

Covert testing assesses real detection and response capability without prior knowledge.
Overt testing allows technical teams to observe, learn and improve during the exercise.

We work with you to determine the most suitable approach during scoping.

Does Red Teaming involve social engineering or phishing?

Social engineering might be included, but it’s often optional and limited in scope. In the case of Evalian’s Red Team Essentials service, social engineering is an additional part of the service.

Red Teaming commonly incorporates Adversary-in-the-Middle (AiTM) phishing to test identity security, MFA resilience and user awareness.

However, safeguards are always applied to control risk and prevent operational disruption.

How long does a Red Team Assessment take?

Our Red Team engagements can take as little as 2 weeks, depending on:

Scope and size of the attack surface
Objectives set
Internal monitoring maturity

Scoping and planning typically take place 1–2 weeks before testing begins.

Is Red Team Testing safe and controlled?

Yes. Every engagement operates under a formal Rules of Engagement (RoE) that defines:

In-scope and out-of-scope systems
Safety controls to protect operations
Communication and escalation procedures

How does Red Teaming support compliance or audit readiness?

Red Teaming provides evidence of control effectiveness, which can support:

ISO 27001 risk management and continual improvement
Cyber Essentials Plus readiness
NIS2, DORA and other sector-specific regulatory obligations

It also provides measurable input into board-level risk reporting.

How often should we conduct a Red Team Assessment?

Most organisations conduct Red Teaming annually or after major system, cloud or identity changes.

However, follow-up testing is often scheduled to validate remediation and improve security maturity over time.
