Challenge	National Oilwell Varco (NOV), a Fortune 500 company supplying technical equipment and services to the global oil-and-gas industry, faced a significant challenge when the entire company had to move to remote access. With operations in over 600 locations and a large computing workforce of 25,000 employees, 70% of whom are mobile with laptops, the shift was not straightforward. The company's fortunes are tied to fluctuating global commodities markets, and after oil prices plummeted in the mid-2010s, the IT team was tasked with doing more with less. They needed to reduce the burden of legacy technical debt, lower historically high costs, add more capabilities, and improve security for their worldwide organization. The company began its transformation in 2016 with a shift to the cloud, away from what CIO Alex Philips describes as 'security appliance hell.' Read More

Solution	NOV invested in Zscaler Internet Access (ZIA) and introduced secure local internet breakouts for its employees. The move was pragmatic: ZIA provided an optimal secure access service edge (SASE) model that optimized SaaS access, and in particular, helped accelerate its Microsoft 365 rollout.

Philips describes this transformation as a 'smart cloud usage approach': moving NOV to the cloud where and when it made sense and on NOV’s own terms. In 2018, Philips and his IT stakeholders began rolling out Zscaler Private Access (ZPA) to secure remote access to internal applications. ZIA and ZPA brought a new level of security to NOV connectivity, enabling protected remote access (for both employees and third-party contractors) and comprehensive inspection of incoming and outgoing SSL/TLS-encrypted data.

NOV invested in Zscaler Internet Access (ZIA) and introduced secure local internet breakouts for its employees. The move was pragmatic: ZIA provided an optimal secure access service edge (SASE) model that optimized SaaS access, and in particular, helped accelerate its Microsoft 365 rollout.

Impact #1	The rapid transition to a remote-access workforce went smoothly despite a few initial connection hiccups. The company was able to support a drastically different new reality: 27,500 employees around the world all needing remote access to work from anywhere. The investment in ZPA set the stage for the company’s shift to remote access, and with Zscaler’s assurance that its globally-distributed SASE cloud could accommodate NOV’s secure-remote-access traffic volume, the company was able to respond effectively to the crisis. The remote-access effort has fostered NOV’s longer-term operational agility.
