Bio
Vincent Blake CISSP ISSMP CCSP
Nadeev, is a rare gem of someone who can cross business, technical and cultural boundaries to deliver high value security solutions. He has an insatiable hunger for learning that improves his and his team’s capability.
Anthony P.
As part of my international team, Nadeev built and strategized on new controls at every level of the cyber kill chain for a large global enterprise. Nadeev distinguished himself as an up-and-coming architect by being able to approach problems from whatever level they required—sometimes from a macro view and sometimes to the level of fine details. To that end, Nadeev was able to embed himself in infrastructure and workplace services teams to ensure our security standards were being followed, or, where needed, that a standard architecture pattern was built, signed off, and implemented across the board. Further, Nadeev’s capacity to build relationships across Sri Lanka, India, the United Kingdom, the United States, and other geographies ensured that our team had extensive visibility and reach across the whole enterprise. He was also a team player, exemplified through his scheduling flexibility and adaptiveness, enabling us to effectively manage security for a global company with teams spanning nearly all time zones. As a skilled professional, Nadeev also demonstrated an uncanny ability to navigate technology from legacy to contemporary. I was especially impressed with Nadeev being able to quickly context switch from talking on one call about managing the minutiae of firewall rules on traditional Cisco security hardware to the next call where we strategized about identity and Zero Trust across products and tech like Azure Windows Virtual Desktop, Microsoft 365, Azure AD, Open ID Connect, SAML, and Kerberos. With all this, Nadeev will add value to whatever technology or security team he is on, and I hope to have the opportunity to work with him again someday.
