After four years of operation, email security firm CipherTrust says it has experienced its most successful quarter to-date, with regard to financial performance and continued product development.

In the first quarter of 2004, CipherTrust says it achieved record sales, and now has an expansive list of customers that includes thousands of deployments worldwide and 30 percent of the Fortune 100.

The Atlanta-based company also attained its seventh consecutive quarter of profitability and experienced exponential growth of its international operations with offices located in six countries.

In addition, on March 8, CipherTrust closed its first institutional round of funding, a $42 million investment co-led by venture capital leaders Battery Ventures and Greylock.

“Celebrating the company’s fourth anniversary in March reminds us the milestones CipherTrust achieved in the first quarter of 2004 are the culmination of four years of intense focus, leading innovation and superior customer service,” said CipherTrust President and CEO Steve Raber. “The momentum with which we have begun 2004 will only increase as the year pushes on, and we will continue to concentrate our efforts on what has made us so successful thus far.”
