Accenture Security helps organizations prepare, protect, detect, respond and recover along all points of the security lifecycle.

Cybersecurity challenges are different for every business in every industry. Leveraging our global resources and advanced technologies, we create integrated, turnkey solutions tailored to our clients’ needs across your entire value chain.

Whether we’re defending against known cyberattacks, detecting and responding to the unknown, or running an entire security operations center, Accenture Security helps clients build cyber resilience to grow with confidence.

Your job

As a penetration tester & offensive security expert, you will become part of a very skilled security team locally in Luxembourg as well as work closely with experts across different countries. You will work on local as well as international projects or varying sizes and complexities.

You will work autonomously on penetration testing assignments on-site as well as remotely for clients and prepare after-action reports with your findings in a structured and concise manner.

At Accenture Security we lead the field with our holistic approach, working carefully with our clients to help them identify and address security challenges. The impact of our work reaches throughout the entire security lifecycle and across value chains end to end, ultimately keeping businesses and end users protected all over the world.

In practice, that might mean deploying cutting-edge security systems, using AI to analyze security risks, or developing defense strategies based on a combination of technology and user behavior. We aren't limited to a single set of tools to deliver security for our clients, so we take a pro‑active and creative approach to finding the best solutions for every security problem.
