Red teaming is a full-scope, realistic simulation of an advanced adversary targeting your organisation. Unlike a penetration test focused on a specific system, a red team engagement targets your people, processes, and technology to test your overall detection and response capability.

What is the difference between red teaming and penetration testing?

Penetration testing is scoped to a specific system or application. Red teaming is an objective-based exercise with no predefined scope — TSO's team uses any means (phishing, physical access, network attacks) to achieve a goal such as accessing sensitive data, mimicking a real APT campaign.

What is a red team in Belgium?

TSO operates as a red team in Belgium — a group of offensive security specialists who simulate sophisticated, nation-state-level attacks against Belgian organisations to test their defences. TSO conducts red team operations across Belgium and Europe.

How long does a red team engagement take?

Red team engagements typically run 4–12 weeks, depending on scope and objectives. TSO works with your organisation to define realistic goals and timelines that provide maximum value without disrupting operations.

What do I get at the end of a red team engagement?

TSO delivers a full attack narrative — every technique used, every control bypassed, every detection gap identified — along with a prioritised remediation plan and an executive summary for board-level reporting.

Red Team Assessments - Offensive Defense & Strategic Guidance

Red teaming is not a checklist — it is an adversary simulation. We emulate specific threat actors targeting your organisation to test whether your security controls, people, and processes would detect and stop a determined attacker.

What We Deliver

Full-Scope Adversary Simulation

Multi-month engagements replicating how advanced threat actors operate — initial access, persistence, lateral movement, and objectives.

TIBER-EU Assessments

Threat intelligence-based red teaming aligned with the European Central Bank's TIBER-EU framework for financial institutions.

Purple Team Exercises

Collaborative sessions with your blue team to validate detection rules, tune SIEM alerts, and transfer attacker knowledge.

Assumed Breach Scenarios

Starting from an already-compromised position to test your detection and response capabilities.

Physical Security Testing

On-site intrusion attempts to test physical controls, tailgating resistance, and social engineering of staff.

Social Engineering Campaigns

Targeted phishing, vishing, and pretexting campaigns as part of the attack chain.

// Our Approach

Engagement Structure

01

Threat Profiling

We develop a threat actor profile relevant to your industry and threat landscape.

02

Initial Access

Multiple attack vectors pursued simultaneously: phishing, external exploitation, physical, supply chain.

03

Persistence

Establishing persistent footholds that survive reboots, AV scans, and credential rotation.

04

Internal Operations

Lateral movement, credential harvesting, and working toward defined objectives.

05

Objective Achievement

Demonstrating the attacker's ability to reach crown jewels — data exfiltration, financial systems, or critical infrastructure.

06

Debrief & Detection Gap Analysis

Detailed review of what was detected, what was missed, and how to close the gaps.
