Alexander Hagenah

Cyber Security Leader

As a proven cyber security leader with over a decade of experience managing, leading, and executing technical and operational tasks across a variety of global growth sectors. My agile approach allows me to quickly adapt to business changes and deliver exceptional solutions.

I have an extensive background working with law enforcement and intelligence agencies in over 50 countries, where I have been instrumental in the development and evaluation of cyber security systems and solutions to address the growing criminal presence in the cyber security realm.

My strong communication skills and ability to connect with technical teams, sales teams, and C-level executives make me a sought-after presenter at conferences such as for Interpol, Europol, ISS World and others focusing on innovative and groundbreaking methods for conducting cyber investigations and combatting cyber crime.

Since 2021, I am working for SIX, where I am building an in-house offensive security team to stay ahead of criminal hackers. Furthermore in 2022, I joined the Technical Advisory Board of HackerOne, the world's leading hacker-powered security platform.
