Prevent cyberattacks before they happen
Penetration Testing
Identify weaknesses before attackers do
How resilient is your organization against cyberattacks? A penetration test (pentest) uncovers vulnerabilities before malicious actors exploit them. We simulate realistic attacks to assess how effective your security truly is. This enables you to proactively strengthen your defenses and protect critical data and systems.
Our specialized approach
Every organization is unique and so are the vulnerabilities within your IT environment. That’s why DeepBlue Security doesn’t offer off-the-shelf solutions. Instead, we deliver tailored penetration tests aligned with your infrastructure, applications, and business processes.
Our security specialists combine advanced tooling with in-depth manual analysis. This hybrid approach not only detects known vulnerabilities but also uncovers complex risks often missed by automated tools. By integrating automated scanning with thorough manual testing, we ensure broad coverage and highly realistic attack scenarios.
Our pentesting services
- Pentest – Identify and assess weaknesses across your IT environment.
- Threat-led pentest – Simulate attacks based on current threat intelligence and adversary TTPs.
- Red teaming – Realistic attack simulations to test your detection and response capabilities.
- Industrial (OT) pentest – Targeted security testing for operational technology and industrial control systems.
- Mobile app pentest – Security assessments for native iOS and Android applications.

Penetrationtest
in 6 steps
Planning: define goals, scope and rules
We determine your objectives, scope and rules for the penetration test. Together, we identify the systems, applications and network segments that you wish to test. In addition, the necessary clearances and documentation will be taken care of.
Reconnaissance:
collect target information
The collection of data regarding the target environment, including IP-addresses, network infrastructure, publicly available information and system configurations. This is essential to identify possible vulnerabilities and weak points that could be abused.
Scanning for vulnerabilities: identifying weaknesses
Scanning the network or the application using automated tools, for known vulnerabilities, like outdated software and weak configurations, to identify security leaks, that could be misused by attackers.
Exploitation: Attempt to breach security
After identifying vulnerabilities, we manually simulate real-world attacks to attempt to gain unauthorized access and validate the severity of the vulnerabilities. Here we distinguish ourselves through our experience and technical knowledge.
Reporting: provide documentation of findings and recommend solutions
Our report documents the findings of the pentest in accordance with at least the ISO 27001 standard. The report includes a description of the identified vulnerabilities, exploitation success and recommendations for improvement of the security of your network or platform.
Remediate and test again
Our penetration testing services include a standard retest to verify that discovered vulnerabilities have been resolved technically correctly. Double checking for complete confidence.
Manual vs. automated pentests
Penetration tests can be executed manually or through automation. Manual pentests provide deeper insights and uncover complex vulnerabilities. Automated tests are faster and more cost-efficient but lack contextual depth. The optimal approach depends on your organization’s architecture and security objectives.
