Strategic Security Advisor

Trusted Advisor, GuidePoint Security

Andrew started his cybersecurity career in 2017 after earning his degree in Business Informatics from Indiana University's Luddy School of Informatics, Computing, and Engineering. He spent four years at IANS Research advising CISOs and security teams across the Fortune 500, learning what it takes to help security leaders make confident, high-stakes decisions. From there, he moved to the vendor side at Silverfort, where he built deep expertise in Identity and Access Management and gained a strong understanding of the broader vendor landscape and ecosystem. Today, Andrew works as a trusted advisor to clients across New England through GuidePoint Security, where his role goes well beyond just recommending tools. He partners closely with security leaders to understand where their real risks live, streamline how their teams operate, and make sure security stays aligned with where the business is headed. Whether he's acting as a technical integrator or a sounding board when a client needs to think something through, Andrew's focus stays on reducing risk and helping organizations move forward with confidence.
