The Journey to Office 365

In January of 2014, Summit Truck Group began their journey to Office 365 when the two companies, who form the nucleus of the group, merged. Each had an on-premises Exchange Server, and the decision was made to migrate the entire company to Office 365 and Exchange Online. They completed five of their migrations by the end of 2014, and migrated the remainder of their dealerships in 2015.

When Summit Truck Group began their transition, they enabled Office 365’s built-in email security: Exchange Online Protection. “We tried EOP and found it did not meet our needs,” explained Michael Norton, VP of Technology for Summit Trucking. “Exchange Online Protection didn’t allow the kind of granular controls we needed for our various locations. We found that adjusting the settings often required we perform message traces to see why false positives had occurred.” Summit IT personnel were familiar with Barracuda appliances, but wanted a cloud-based email security solution.

The two on-premises servers being replaced ran different email filters—one was a Cisco product, and the other was a Barracuda Email Security Gateway. They preferred the Barracuda interface over the Cisco product and chose to implement Barracuda’s cloud-based Email Security Service.

"Setting up Barracuda’s Email Security Service was phenomenally easy."
- Michael Norton, VP of Technology, Summit Truck Group

One Word: Easy

So far, they have been very impressed with the product’s capabilities with Barracuda’s support. “Setup was phenomenally easy,” Michael noted. They have had no issues with the service, and one brief outage was immediately followed-up with a letter from a top Barracuda executive. “One of the best things about Barracuda’s email security service is the support,” Michael said. Whenever they have had a question or needed to change a setting, Barracuda’s response has been instantaneous.

Michael has nothing but praise for Barracuda’s email security service—it has been easy to use, has corrected the issues they had with junk and false positives using Exchange Online Protection, and the service is easy to manage.“Simple and easy – says it all,” stated Michael.


The Barracuda Email Security Service satisfied Summit Truck Group’s need for an email filtering solution that would eliminate junk, lower the number of false positives that occurred, and provide straightforward, easy management. Barracuda’s cloud-based Email Security Service was chosen based on previous experience with Barracuda’s appliance products, and the service gets high praise for its ease of use and solid features.
