Technical assurance, pen testing and red teaming: offensive security

Offensive security services to identify, validate and remediate technical cyber risks.

Thales technical assurance and testing services simulate real-world cyberattacks to uncover vulnerabilities in systems, applications and people, and deliver prioritised remediation guidance. Most cyberattacks exploit known but unremediated vulnerabilities.

How Thales helps customers

Enhance your cyber resilience with expert-led testing, realistic attack simulations and actionable recommendations.

Proven expertise

Over two decades of offensive security experience and thousands of engagements underpin our methodology. Our experts simulate realistic cyberattacks to rigorously assess systems, applications, networks and people, providing reliable, repeatable and high quality testing outcomes.
Full threat coverage

From network and infrastructure to applications, cloud, wireless, OT/ICS/IoT, AI systems and human factors, Thales covers the full spectrum of technical assurance and testing to identify exploitable vulnerabilities across your entire digital and physical environment.
Business aligned testing

We start by understanding your business context, threat landscape and regulatory constraints, then tailor our testing scopes and scenarios, including red teaming, TIBER-EU TLPT, application and code reviews, to focus on the risks that matter most to your organisation. Testing scenarios are tailored to your business objectives, critical assets and regulatory obligations to maximise operational value.
Improved detection

Adversary simulations, red/blue/purple team exercises and social-engineering campaigns help you evaluate and improve SOC maturity, detection rules, incident response playbooks and cross-team coordination. This includes validation of SIEM use cases, SOAR playbooks and incident response procedures, boosting your ability to detect and respond to real attacks.
Upskilling and awareness

Beyond testing, Thales helps upskill your teams through cybersecurity training and awareness programmes, sharing insights from real world engagements so development, IT, SOC and business stakeholders can better anticipate, detect and respond to cyber threats.
Global cyber presence

With 40+ years of cybersecurity expertise, 8 SOCs and 6,000 cybersecurity experts in 148 countries, Thales provides global coverage and local understanding to help major enterprises and critical industries strengthen their technical security posture.

Technical assurance and security testing

Technical Assurance and testing evaluates the security of systems, applications, networks and people before attackers can exploit them, helping organisations reduce breach risk, prioritise remediation and avoid costly security incidents. Thales’ offensive cybersecurity experts use proven methodologies, combining automated tools with in-depth manual techniques, to simulate real-world attacks, identify vulnerabilities and provide prioritised remediation recommendations that help organisations achieve these outcomes more effectively.

From standard penetration tests to specialist TIBER‑EU TLPT and AI, OT/ICS/IoT or application security assessments, Thales helps you understand the real technical risks and consequences of cyberattacks. Offensive security testing is a strategic capability to anticipate attacks and protect critical business operations. We identify and validate exploitable vulnerabilities, then provide clear, prioritised remediation plans to improve detection, response and overall cyber resilience.

End-to-End penetration testing

Thales conducts penetration tests beyond vulnerability scanning by simulating realistic attacks across IT and OT environments. Our assessments cover networks and infrastructure, web, mobile and custom applications, APIs, cloud workloads, wireless technologies, IoT devices and AI systems. Based on the Thales methodology and OWASP Testing Guide, we combine automated tools with expert manual testing to validate exploitable vulnerabilities, assess API authentication, authorisation and input validation, and deliver prioritised remediation guidance aligned with operational and regulatory requirements.

Beyond penetration testing

Adversary testing simulates real attacks using the tactics, techniques and procedures of genuine threat actors. Goal-oriented exercises (e.g. “reach the crown jewels”) test the effectiveness of controls, detection rules and incident response through phishing, malware, ransomware, DoS/DDoS and unauthorised access scenarios. Thales delivers structured findings and recommendations to improve detection, response and resilience.

Learn how offensive and defensive teams work together to strengthen cyber resilience. Red Teams emulate real-world attackers to assess security posture and resilience. Blue Teams monitor, detect, respond to and remediate cyber threats. Purple Teams bring both disciplines together to improve collaboration, validate SIEM and SOAR capabilities, and strengthen SOC maturity.

People and physical sites are often the weakest link. Thales performs physical penetration tests (e.g. buildings, server rooms, workstations), social engineering campaigns (phishing, vishing, pretexting, tailgating) and insider threat simulations to validate security policies and raise awareness, improving your ability to detect and block social engineering attacks.

Thales partners with your development teams to embed security into the SDLC. We perform application penetration tests, secure code and architecture reviews, and integrate security testing into DevSecOps and CI/CD pipelines. Using static and dynamic analysis, we uncover issues missed by standard tests and ensure applications are secure by design.

TIBER-EU Threat-led Penetration Testing

Thales helps financial institutions and critical entities run TIBER-EU aligned, threat-led penetration tests that simulate sophisticated attacks on critical systems, validate resilience and support European regulatory expectations.
