Red Teaming

We assess how far a realistic threat actor can progress across people, processes and technology. Each scenario reflects your threat profile and tests prevention, detection and response under operational conditions. Our activities are mapped to MITRE ATT&CK and can support TIBER-EU and other threat-led testing programmes.

Cybersecurity expertise for mission-critical sectors

Organisations operating in mission-critical sectors face distinct threat actors, attack surfaces and regulatory requirements. Effective security therefore requires more than generic controls. It requires technical validation within the operational, legal and sector-specific context. Assessments focus on the attack paths, dependencies and failure scenarios that can affect continuity, safety, integrity and trust.

Healthcare

Cybersecurity incidents in healthcare can affect both patient safety and continuity of care. Electronic health records, medical devices, diagnostic systems, identity platforms and connected care environments create attack paths across clinical IT, medical IoT and supporting infrastructure. Assessments are performed carefully and non-disruptively, with findings translated into technical priorities for security teams, IT management and healthcare leadership.

Frequently asked questions

When does my organisation need a penetration test?

A penetration test is relevant when an organisation needs to know whether vulnerabilities can actually be exploited. Typical moments include a major change, a go-live, a compliance requirement or a request for evidence from clients, auditors and insurers.

What is the difference between a vulnerability scan and a penetration test?

A vulnerability scan uses tooling to find known vulnerabilities. A penetration test manually validates whether those vulnerabilities are exploitable and what impact they have. DeepBlue combines tooling with manual analysis by senior specialists.

What do we receive after a penetration test?

The organisation receives a clear report with technical findings, risk assessment, supporting evidence, impact analysis and concrete remediation guidance. An executive summary and a retest are a standard part of our approach.

Can you help if we are dealing with a cyber incident?

Yes. For existing clients, DeepBlue supports incident response, forensic investigation, containment, malware analysis and remediation guidance. The first focus is regaining control, preserving evidence and preventing further damage.

How does DeepBlue help with NIS2, DORA or ISO 27001?

We translate compliance requirements into practical security measures. This includes gap assessments, technical validation, governance, incident response processes, risk analyses and improvement roadmaps. DORA is mainly relevant for financial organisations. NIS2 applies more broadly to essential and important sectors.

Can you test without disrupting our operations?

Yes. DeepBlue adapts every test to the environment, the risks and the operational constraints. In complex IT and OT environments we explicitly account for continuity, production impact, safety and existing management processes.

What makes DeepBlue different from a standard cybersecurity supplier?

Our background, knowledge and experience make us specialists rather than generalists. DeepBlue works exclusively with certified and experienced senior security specialists. We deliver technically validated findings, direct communication and tailored advice rather than generic scanner output.

Can you also provide structural support over a longer period?

Yes. DeepBlue supports organisations on a structural basis through framework agreements for longer periods where required. We also deliver CISO as a Service, managed SOC, incident response, red teaming, compliance & governance and training.
