Offensive Security

Are you pushing your services and business fundamentals further into the land of digitalization? Doing so exposes your business increasingly to cyber-attacks and it will be abused by cyber-criminals at some point. Increasing your cyber resilience is the only option and cannot be achieved without continuous assessments on your ever-changing IT environment. NVISO can assist you by performing structured assessments and prioritising your cyber-security implementation plans.

Your Challenge

You have been tasked to increase your businesses efficiencies by digitalizing the processes and surrounding applications. Doing so increases the cyber threats you face as an organization and on the other hand your clients consistently request a view on the latest assessment reports to ensure their cyber-resilience does not deteriorate by implementing your service.

Are you sufficiently prepared?

  • When was the last time you have performed a review of your environment or application to identify vulnerabilities?
  • Do you have the right tooling and processes in place to ensure new deployments are always verified on cyber-vulnerabilities before being released?
  • Have you simulated a realistic attack or advanced adversary attempting to reach your business-critical systems and data?
  • Is your SOC able to detect such an attack and how do they respond?

Our team of ethical hackers can conduct penetration tests on your organization and application, simulating advanced adversaries attempting to reach your crown-jewels.

Our Solutions

Application Based Security Testing

Our ethical hackers assess vulnerabilities in your mobile, web, or desktop app. Tailored test-cases align with threats and unique features, providing insights to enhance security. Show clients a trusted supplier reviewed the latest version.

Internet of Things Assessment

We review the entire ecosystem to identify attack vectors. Our experts perform comprehensive testing on devices and linked applications. Protect against increased attack surfaces and secure your IoT technology.

Cloud Security Assessment

We can review your current cloud security posture, identify and prioritize risks and recommendations to improve your posture on your infrastructure, containers, as well as pentesting your cloud environment. 

Red Team

We will assess people, processes, and technology to provide a complete picture of your cyber resilience. This is done through the simulation of a realistic attack, based on tactics, techniques, and procedures (TTP) along a kill chain. Our goals: to determine the impact of a realistic attack, assess your detection and prevention and identify main improvement areas.


We are a trusted supplier for TIBER exercises and have extensive knowledge of its implementation throughout Europe. Our experts can perform both the targeted threat intelligence and red team phases with separate, dedicated teams. This unique offering allows us to bring added value to any TIBER exercise.

Purple Team

Using the knowledge and expertise of our Red Team, as well as our Detect & Response services, we are able to offer high-class Purple Teaming to assess and improve your cyber security posture with a focus on detection use cases. Choose ad-hoc projects or continuous breach and attack simulations.

We will assist you in identifying vulnerabilities before actual cyber-criminals do.
