Join our daily and weekly newsletters for the latest updates and exclusive content on industry-leading AI coverage. Learn More. National Oilwell Varco (NOV) is undergoing a sweeping cybersecurity transformation under CIO Alex Philips, embracing a Zero Trust architecture, strengthening identity defenses and infusing AI into security operations. While the journey is not complete, the results, by all accounts, are dramatic – a 35-fold drop in security events, the elimination of malware-related PC reimaging and millions saved by scrapping legacy “appliance hell” hardware.VentureBeat recently sat down (virtually) for this in-depth interview where Philips details how NOV achieved these outcomes with Zscaler’s Zero Trust platform, aggressive identity protections and a generative AI “co-worker” for its security team.He also shares how he keeps NOV’s board engaged on cyber risk amid a global threat landscape where 79% of attacks to gain initial access are malware-free, and adversaries can move from breach to break out in as little as 51 seconds.Below are excerpts of Philips’ recent interview with VentureBeat:VentureBeat: Alex, NOV went “all in” on Zero Trust a number of years ago – what were the standout gains?Alex Philips: When we started, we were a traditional castle-and-moat model that wasn’t keeping up.
