When is a penetration test necessary?

  • In response to current security incidents
  • When developing new applications and products
  • In preparation for compliance audits
  • As part of the path to digital transformation
  • For your brand protection and good publicity

Our penetration tests

Web applications

Web applications are permanently available to hackers and are filled to the brim with data, making them an attractive target.

Mobile apps

With the enormous spread of mobile applications, the need for reliable security tests to protect systems and data is also increasing.


The main goal is to find vulnerabilities in the infrastructure that could serve as entry points into private areas of your network.

Penetration Testing as a Service

Continuous security testing uses 24/7/365 automated vulnerability monitoring and targeted manual analysis to provide detailed, real-time, risk-graded reports on the systems and vulnerabilities in your internal and external attack surface.

Incorporated into a proactive patching and remediation plan, as well as the overall Systems Development Life Cycle (SDLC), these insights can help reduce the risk window between individual strategic penetration tests.

Red Teaming

Unlike penetration testing, which aims to uncover all of a system’s vulnerabilities, Red Teaming focuses on a specific target linked to the cyber kill chain to show whether an attacker could do the same.

Red team exercises are conducted using a black box testing approach where no information is given about the target company. This allows the test to mimic a real attack from the outside, starting with reconnaissance.

In competitive operations, the client’s own blue (defensive) team will attempt to prevent, detect and respond to the simulated attack.
