Paul Huijbregts

With almost 20 years of industry experience and relevant certifications, Paul Huijbregts has a long history of working with customers across the world leveraging his passion for (Microsoft) security solutions – and being brutally honest about them. After joining Microsoft in 2016 and engaging regularly with Defender for Endpoint teams, Paul moved to Redmond (together with his wife and kids) to join them and become a product manager – in the middle of the pandemic (October 2020). Here, he is on what is called the “Platforms” team, working on solutions across operating systems and environments, focusing primarily on server endpoints and security management. His motto is: “I drink beer and I know Microsoft security things.”
