CYBERSECURITY | SAFETY & SECURITY


all web traffic in a virtual browser, far from the user’s device — shutting down malware access to the endpoint. While it proved to be a highly secure, highly reliable technology that allowed users to browse the web and access email without putting the organisation at risk, it had its challenges. ThinApp is rarely updated by VMware, so much of the regular maintenance had to be done by Gösgen’s IT team. Even then, the team could not guarantee that every client on every user device was up to date. According to Manuela Schweizer, Security and Network


Engineer for Gösgen, they, “were falling behind more and more. The workload of preparing Firefox for virtual deployment was considerable. That’s why we looked for a new solution that would keep up with browser development and reduce workload.” Schweizer and François Gasser, Gösgen’s IT security


officer, worked with BOLL Engineering and BNC Business Network Communications AG, the plant’s IT consulting and implementation partner, to find an isolation solution that would enable a native browsing experience for users while protecting against email and web-based threats. The solution also needed to reduce the maintenance burden on the IT staff. Trials were set up, including the Menlo Security Cloud


Platform. The Menlo solution works by moving the ‘fetch’ and ‘execute’ commands off the end device (such as a mobile phone or laptop) and into a closed virtual browser


environment. Only safe content is rendered to the user’s browser. All active code, including JavaScript and Flash, is executed in the virtual browser environment, where it has no access to the user’s machine. Instead, users receive a rendered web page that has all the active code stripped out via a proxy service that removes scripts and automatically converts Flash videos to MP4 files. This eliminates the need to install any client software on endpoints, allowing users to access the web, links, and documents in emails with no impact on speed, performance, or the native experience. Gösgen now has a web security solution capable of delivering traditional web filtering control and access, with malware protection. Because of data privacy issues, Gösgen deployed the Menlo solution in a private cloud environment built and maintained by its own IT team. All employees were informed about the new platform via the company intranet, but training was unnecessary. In fact, users are completely unaware of the underlying technology they are using, allowing them to get with their work without any impact. All 550 employees at the plant, plus a few external


partners, can now surf the web productively and safely. More important for the team at Gösgen is knowing that no malicious code can reach users’ devices, so they can sit back, relax and allow employees to access websites that previously had to be blocked. ■
