For a network operator like TasRail, successfully maintaining service requires business operations to be available 24×7. So when a ransomware attack slipped past the organisation’s legacy security solution, its 4-person IT team realised it was time for a different approach to messaging security.

Although the ransomware was stopped before it caused any damage, the event highlighted the limitations of onpremises security. With ransomware rife and business email compromise (BEC) emails appearing more frequently, TasRail recognised that cloud-based systems like Microsoft Office 365 promised a highly available messaging environment for its 250 highly mobile field staff, officebased workers and shift workers

Based on word-of-mouth recommendation, TasRail ICT Manager Andrew Quill began investigating Mimecast’s suite of cloud-based message protection tools and quickly realised it was the perfect fit for the company’s needs. The firm implemented Mimecast Email Security and began seeing benefits from day one.

“Anything that might slow down our communications is an issue,” Quill explained. “We wanted a solution that would maintain a high percentage of active threat detection, but at the same time reduce the number of false positives. From the day we turned Mimecast on, all the noise went away.”

Users were initially surprised at how quiet their email environment had become but rapidly became used to using desktop and mobile interfaces to interact with the Mimecast environment. The system’s extensive reporting has improved visibility of the actual threats targeting the company, while the recent addition of journaling and the Mimecast M2A bundle have combined robust cloud-based security with message archiving and high availability.

TasRail’s Mimecast shift has allowed it to modernise and secure its communications infrastructure as well as paving the way for an increasingly cloud-based future. In the short term, Quill added, the Mimecast transition has smoothed daily operations – with the confidence that users won’t be compromised by BEC messages, ransomware, and malicious URLs.

Not only has the user experience been significantly improved, but the Mimecast platform has engendered “a significant drop in email-related support calls”, he said, estimating that the volume of support calls is down 80 percent over pre Mimecast levels. Translating this into avoided costs suggests that the new environment is saving TasRail thousands of dollars per month.

Success with Mimecast email filtering paved the way for a greater investment in Mimecast M2A archiving and business continuity capabilities. This saved the firm from having to implement a separate standalone backup tool, which would have complicated its Office 365 environment and introduced a significant cost and administrative burden.
