Have a pentest performed
One vulnerability is enough
What a DEFION pentest concretely delivers to you
- Realistic attack simulation by experienced ethical hackers
- Insight into vulnerabilities and how they can be combined or exploited
- Risk prioritization based on your specific business context and impact
- Report at both technical and management levels — without unnecessary noise
- Concrete improvement actions, directly applicable for your teams
- Re-test after remediation possible — so you can be sure it is closed
Which pentest suits your situation?
Depending on your IT landscape and objectives, we perform different types of tests:
Web Application Pentest
Thorough testing of web applications and APIs according to OWASP and CVSS. Grey-box as standard, black- or white-box on request. For organizations with customer portals, SaaS products, or critical web environments.
Internal Pentest
Simulation of an attacker who is already inside - via a compromised employee, supplier, or device. The Active Directory is assessed for permission structure, presence of weak passwords, and possibilities for lateral movement. Additionally, we perform an assessment of the Microsoft 365 environment (configuration, access rights, and possible data exposure), the WiFi networks and virtual workplaces such as Citrix and thin clients, and the hardening of workstations and laptops based on best practices.
External Pentest
Attack simulation from the perspective of an external attacker. What is visible from the internet, which services are unintentionally accessible, and what can an attacker achieve with that? Including Leaked Credentials Analysis - are your employees' passwords from previous data breaches still usable?
OT Pentest
Controlled attack simulation on industrial environments and process control. DEFION has specifically adapted the test methodology for OT environments - to minimize impact on availability and correct operation. Prior to the test, DEFION discusses all risks with your team. Test scenarios are tailored to your specific architecture: network segmentation, authentication, supplier access, and secured components.
Cloud Security Assessment
Assessment of your cloud environment on Identity & Access Management, network security, storage configuration, security monitoring, and compliance. Including consultation with your cloud administrator to put findings into context.
Red Team Engagement
Advanced, scenario-driven attack simulation focused on your full detection and response capability. Not only technical vulnerabilities — also people, processes, and physical access.
During the intake, we determine together which approach is appropriate.
How a pentest at DEFION proceeds
-
Scope & intake: We determine objectives, systems, and conditions together. The security specialist creates a test plan with exact scope, IP addresses, URLs, and attack perspective.
-
Testing phase — Manual attack simulation by an experienced ethical hacker. Methodical and controlled — within the agreed scope, with attention to operational continuity.
-
Reporting & prioritization — Clear report with findings at both technical and management levels. Risks prioritized based on business impact. No generic list — but directly applicable insights.
-
Report discussion — Personal explanation of the findings by the executing specialist. So your team understands what was found and what should be addressed first.
-
Validation — After remediation, we retest the mitigations. So you can be sure the vulnerability is actually closed.
"With DEFION we have made enormous progress. The sense of control is greater. The specialists are very technical and passionate about their field. This clearly shows in their services." FuturumShop, e-commerce client
"Thanks to DEFION, we benefit from up-to-date knowledge about contemporary security threats and means to avert risks. We have peace of mind knowing we are fully supported 24/7 by their team.”
“The sector and the partners we work with maintain increasingly high security standards for IoT-products and services. Protecting the privacy of individuals in the images and the sensitivity of the information the drones collect, such as on objects in critical infrastructure, requires our security to be airtight. With Defion, we are working with a professional partner who can support us at the right level. The collaboration also fits perfectly within our strategy to deliver reliable and secure drone technology to European customers.”
“New requirements from NIS2 for OT systems are increasing the focus on security. With Defion, we know we have the right expertise in-house to keep our systems secure. The collaboration was easy and pleasant; the specialists truly sat next to us rather than across from us. Thanks to their openness and expertise, we are working together toward the same goal: optimal security. This gives us the confidence to face the future.”
“If you look at where we were ten years ago, we’ve made enormous progress. The sense of control is greater. With Security Assurance and MDR we have set up processes and control mechanisms that allow us to limit the impact of a potential attack. The collaboration also serves as a constant reminder to maintain focus on security and set the right priorities in that area. It keeps us alert and sharp. Moreover, Defion’s specialists are highly technical and passionate about their field. That clearly shows in their services.”
For which organizations do we perform pentests?
Our pentests are performed for all kinds of organizations in various sectors:
- With business-critical IT environments
- In highly regulated sectors, such as critical infrastructure, finance, and government
- With in-house development teams
- That want certainty instead of assumptions
