A penetration test is an authorised, controlled attempt to find and exploit weaknesses in your applications, networks and configurations before someone else does. A vulnerability assessment is the broader, systematic scan for known weaknesses. Together they show where you are exposed and what to fix first.
TEMERON lists penetration testing and red teaming among its cybersecurity competencies, next to vulnerability assessment, security monitoring and incident response.
What we look at
- Web applications and APIs, including the software we did not build ourselves.
- Cloud, on-premise and hybrid infrastructure: exposed services, configuration, access control.
- Vulnerability assessment against known weaknesses, with findings mapped to MITRE ATT&CK where useful.
- Re-testing after remediation, so you can show the issue is closed.
From findings to fixes
A report is only useful if it leads to change. Because TEMERON also develops software and hardens infrastructure, we can help your team fix what the test found: secure configuration, access management, CI/CD pipeline hardening and security-by-design in new development. Findings can also feed continuous monitoring with TEMERON's XDR, our own Wazuh deployment.
Testing and NIS2
NIS2 does not prescribe penetration tests by name, but its risk-management measures include security in development and maintenance "including vulnerability handling and disclosure" and "policies and procedures to assess the effectiveness of cybersecurity risk-management measures" (Directive (EU) 2022/2555, Art. 21(2)(e) and (f)). Regular testing is one way to produce that evidence.
Frequently asked questions
What is the difference between a vulnerability assessment and a penetration test?
A vulnerability assessment systematically identifies known weaknesses. A penetration test goes further: it tries to exploit them, within an agreed scope, to show what an attacker could actually reach.
Is a penetration test required by NIS2?
NIS2 does not name penetration testing. It requires vulnerability handling and procedures to assess the effectiveness of security measures (Art. 21(2)(e) and (f)); testing is a common way to meet and evidence these requirements.
Will testing disrupt our systems?
Scope, timing and test methods are agreed in writing before any testing starts, so the exercise stays controlled. Production-sensitive systems can be tested in agreed windows or in a staging environment.
Can you help fix what you find?
Yes. TEMERON also develops software and hardens infrastructure, so remediation support and a re-test can follow the report.
