Pillar Security, a leading AI security company, today announced that esteemed product innovator and cybersecurity entrepreneur Brandon Dixon has joined the company’s Advisory Board as a Strategic Advisor.

Dixon brings a distinguished track record spanning entrepreneurial ventures and enterprise transformation. As co-founder of threat intelligence pioneer PassiveTotal, he guided the company from inception through its acquisition by RiskIQ, where he continued as a key architect of product strategy leading to RiskIQ's eventual acquisition by Microsoft. Most recently serving as Security AI Strategist at Microsoft, Dixon spearheaded the launch of Microsoft Security Copilot and drove critical advancements in Defender Threat Intelligence and External Attack Surface Management.

"Brandon embodies the exact blend of entrepreneurial vision and enterprise operational excellence that defines our approach at Pillar," said Dor Sarig, CEO & Co-founder of Pillar Security. "His experience building Microsoft Security Copilot from the ground up gives him unique insight into both the opportunities and challenges enterprises face when deploying AI. This expertise will be instrumental as we accelerate our mission to help companies build trust in their AI systems.

"I'm excited to join Pillar's journey," said Dixon. "This team has built something truly differentiated - a foundational security platform that understands AI systems at their core. Pillar's team has that rare combination of deep security expertise and AI innovation that will define the next generation of enterprise security. They're not just keeping pace with AI evolution - they're anticipating where AI threats will emerge and building proactive defenses today."

"Few people understand the intersection of AI and security as deeply as Brandon," said Elias Manousos, lead investor at Shield Capital and former CVP at Microsoft responsible for AI Copilot for Security and Threat Intelligence. "Brandon has been at the forefront of two of the biggest shifts in cybersecurity: the rise of threat intelligence and the emergence of AI-driven security operations. That expertise will be invaluable as Pillar scales its platform to meet the explosive demand for AI security solutions."

This appointment builds on Pillar Security’s ongoing momentum as a seed-funded company, highlighted recently by the addition of GTM veteran Jenna Raby as SVP of Growth.
