MAN Energy Solutions, a leading provider of largebore diesel engines and turbomachinery, was facing challenges due to rapid technological changes, particularly in the field of IoT. With engines and systems of all sizes deployed globally, many of which were in motion, the company was struggling to keep up with the pace of change. Additionally, the company's large and distributed global workforce was increasingly mobile, requiring mobile access to web apps and custom business applications. The traditional approaches to network and app security were proving inadequate for the modern cloud deployments that enabled global scale and access. The company was seeking a solution that would make these applications dark to the internet, with authenticated access only between trusted users and trusted applications. The improved speed and agility gained in cloud deployment was being offset by a poor user experience associated with accessing apps through legacy corporate VPN solutions, with increasing appliance, software, and MPLS networking costs. Furthermore, there was a desire to gain security advantages associated with making the apps invisible on the internet.

MAN Energy Solutions turned to Zscaler in 2011 to improve user experience, reduce bandwidth cost, and meet increasing security objectives. The company started by connecting globally distributed mobile users to their SaaS applications using Zscaler Internet Access (ZIA). Zscaler was later selected to address advanced persistent threat (APT) requirements. Next, Zscaler Private Access (ZPA) was selected to provide anywhere any time access for the mobile workforce and contractors to apps running on premises. Most recently, ZPA was introduced for secure access to apps running on AWS and Azure, improving mobile user experience while reducing networking costs. Zscaler Private Access (ZPA) provides policy-based, secure access to private applications and assets without the cost, complexity, or security risks of a VPN. The Zero Trust Model approach makes services invisible, and both apps and users need to be authorized using SAML before user access is established. This approach also prevents the ability for malicious software to move laterally, ensuring that access is initiated only by a client to a server, and never the other way around.

The implementation of Zscaler's solutions has resulted in a number of operational benefits for MAN Energy Solutions. The company has been able to deliver a better experience for end users, with improved access to applications and a reduction in the attack surface via application access without network access. The solution has also enabled strong authentication and granular application access control on a global scale. The ability to deploy, and securely access and manage VPCs has been a significant advantage, as has the ability to ensure an optimal path between users and apps for increased performance. The company has also gained increased visibility into applications and user activity, which has further enhanced its security posture.
