I am pleased to write this letter on behalf of Techni-Core Network Services. Techni-Core provides ERC with IT support services in system and network administration, storage, and network security. We have relied on their services for more than 4 years and anticipate continuing our relationship in the future. They have provided outstanding service in quality, responsiveness, and helpful support. Techni-Core comes when we need them, whether it is in the middle of the workweek or Sunday night, and they make sure our issues are resolved.

We could not succeed in business without a well-designed network with safeguards for backing up data and protection from hackers and viruses. We rely on Techni-Core to keep our IT infrastructure up and running.

Sincerely,
President and CEO

SEI GROUP contracted for network support services from Techni-Core in August of 2001. Since that time, we have expanded our offices threefold, added servers, a hardware firewall, hosted our own ftp site and implemented VPN capability. Our business, like many, requires continuous ‘up-time’ in order to service our customers and allow our personnel access when they need to work. Our electronic business assets must be fully operational and first rate, or we cannot deliver the products and service our customers require.

With Techni-Core, we have found the technical capability outstanding and service response times to be very good. In selecting Techni-Core, SEI had other choices. We determined that Techni-Core would offer the best combination of professional capability at a reasonable fee. SEI is pleased with our decision to use Techni-Core. We have no problems recommending Techni-Core to anyone.

Sincerely,
Vice President, Operations

Techni-Core has been servicing our computer technology needs since 2000. In those years we have installed ever more complicated systems to facilitate electronic time keeping for payroll, Deltek GCS Premier accounting software operating on an internal network with 3 users, and a local network with 8 users on an internal server. Techni-Core, and in particular Lawrence Taylor-Duncan, has been totally responsive to our needs. They usually are here within an hour of the time we call with a problem, depending on the severity of the problem. We especially appreciated the level of effort from Techni-Core when systems go down. We have found that the personnel from Techni-Core in general have a level of expertise and initiative that insures that we get the best support and the quickest service available.

One of the most valuable things Techni-Core does for us is to prevent problems by keeping us up to date with the latest tools to prevent unauthorized user access to our systems and control email problems before they can occur. We don’t let anyone but Techni-Core have access to work on our computers and networks.

Lawrence,

I am very pleased with the job Jason did for us. He installed the service pack to the server and all three users without a hitch. He came back this morning and installed Windows 2000 to one of the computers we will give away. He did an excellent job. Just wanted to let you know we were happy with him.

I just wanted you to know how pleased we are to be working with Technicore and Jason. Jason has done a really good job with what has been a total mess and difficult situation. I've had good comments on his professionalism, how hard he works, and his knowledge. I have also had the opportunity to work with him quite a bit personally and can also say he is great. Needless to say, we are very pleased with Jason and having you guys on board.

Thanks.
