What we do

We commit our expertise to meet your business needs.

Penetration tests

Fenrisk helps you securing your applications by putting its expertise to your service. Penetration tests aim to identify vulnerabilities in your systems by using the same techniques an attacker would. For each vulnerability identified, Fenrisk proposes a suitable remediation that takes into account your context and technical contraints.

Examples of carried out assessments
  • Web site or application
  • Mobile applications
  • Corporate network
  • Industrial information system
  • IoT device
Large scale assessments

Take back the control on your external perimeter. Fenrisk performs large scale penetration tests by starting with a phase of reconnaissance. It helps you to draw up an inventory of the visible parts of your perimeter. In a second part, we focus on finding critical paths that could lead an attacker to breach into sensitive assets or even reach your internal network. In the same way as a regular penetration test, we provide you with all the mandatory information to test discovered vulnerabilities and we focus on finding the best technical remediation for your teams to implement.

3 phases
  • Reconnaissance: Get the cartography of your exposed perimeter
  • Security assessment: Full-scale penetration test, focusing on critical paths to your sensitive assets
  • Reporting: We help you finding the best technical remediation
Security audit

When black or grey-box tests are not comprehensive enough, we also propose white-box assessments to get into details and unveil deep-rooted vulnerabilities. We work alongside you to identify the most sneaky ones hidden in your applications, systems and networks.

Examples of security audits
  • Source code audit
  • Corporate computer configuration audit
  • Active Directory configuration audit
  • Architecture review
  • Network device configuration audit
