MILFORD, CT – March 11, 2008 – Perimeter eSecurity, the only provider of Complete Security On Demand, announced the appointment of former Counterpane Sales Executive, Rob Bolton, to the position of North American Regional Vice President of Sales for Perimeter eSecurity and USA.NET. USA.NET is a wholly-owned subsidiary of Perimeter eSecurity and the leading provider of secure Microsoft® Exchange Hosting and eMessaging services.

As the North American Regional Sales VP for Global Accounts (Fortune Ranked Companies), Mr. Bolton will be responsible for the enterprise sales strategy of both Perimeter eSecurity and its USA.NET subsidiary and for revenue growth within the company’s rapidly growing large enterprise market.

“We are very excited that Rob Bolton has joined Perimeter eSecurity and USA.NET,” said Doug Howard, Chief Strategy Officer of Perimeter eSecurity and President of USA.NET. “Over the past two years we have selectively built our Fortune 1000 customer base and developed scalable and repeatable Software as a Service (SaaS) solutions that address the complex needs of these companies. More importantly, we have taken our expertise in compliance, developed while servicing our 5,500 customers – a majority of which are in the financial services and healthcare verticals – and have been able to bundle extremely cost-effective, high quality solutions in a market that typically must pay high premiums for mediocre services.”

“I’m thrilled to join such a dynamic, forward thinking organization,” Bolton said. “I was impressed with the positive feedback I received from customers about the USA.NET solutions. It became clear that we solve major challenges for organizations through the delivery of the most comprehensive suite of solutions in the industry, including hosted Exchange, commercial messaging, anti-virus/anti-spam, content filtering, email archiving, encrypted email, secure IM, wireless email, integrated SharePoint® services, as well as backup and disaster recovery. Large enterprises still have a need for the migration services and custom designed messaging solutions that we provide. I’m even more excited now that we are packaging solutions that combine the best services from both Perimeter and USA.NET. Perimeter eSecurity and USA.NET are at a very exciting point in the company’s history and I am proud to be a part of it.”

Prior to joining the company, Mr. Bolton ran a sales territory for BT Counterpane where he provided sales leadership and revenue acquisition through BT Counterpane’s core security monitoring and management services. In addition, Mr. Bolton assisted in the design and implementation of many of the BT Counterpane sales best practices, including sales training programs, lead generation activities, corporate presentations, and the overall enterprise sales process. Prior to that, Mr. Bolton held senior management and sales positions with Redsiren, International Network Services, and GE Capital IT Solutions.
“Rob has had a lot of success leading enterprise sales teams targeted at the Fortune 1000 within the IT security and network infrastructure markets,” added Howard. “He will lead the team focused on selling the USA.NET integrated email hosting solution suite and professional services. Rob is a great addition to an already great team.”
