Upcoming Speaking Engagements

As a Microsoft 365 Modern Workplace consultant Joost helps customers implement modern workplace solutions based on top of their Microsoft 365 licensing, leveraging products like Microsoft Intune, Microsoft Entra, Microsoft Defender, Exchange Online, Microsoft Teams, I constantly build solutions which span these products, taking into account Security, Usability and Manageability as main pillars. Currently he is also responsible for the delivery of Secure At Work, a product which can automatically provision Microsoft 365 tenants with best practices configuration and once onboarded keeps customers up to date by using regular releases. Each release adds or updates functionality in Microsoft 365 environments based on best practices and lessons learned from implementation feedback. The Secure At Work solution is already running on more than 15K+ endpoints, making it proven solution and able to cover 80% of business requirements.
