With over 20 years of experience in IT and cybersecurity, I’ve built my career at the intersection of architecture, security strategy, and real-world implementation. My focus has always been clear: helping organizations and professionals move beyond theory and apply Microsoft security where it truly matters, in production environments. I hold 12 Microsoft certifications, academic backgrounds in networking and information security, and extensive hands-on experience across Azure, Entra ID, Intune, Defender, Purview, and M365 Security.

As the creator of the Marcus Vinícius YouTube channel, I share practical, accessible security content with a growing global audience. I believe knowledge only has value when it creates impact, and my mission is to help professionals build real security, real skills, and real careers, not just collect certifications.
