DENVER -- MX Logic Inc., a leading provider of innovative, easy-to-use email defense solutions for small and medium-sized businesses, today announced that companies with fewer than 1,000 employees receive almost 14 percent more spam through the MX LogicR Threat Center than companies with 1,000 to 2,500 employees.

As the only email defense company focused exclusively on the needs of SMBs, MX Logic now analyzes spam traffic by company size. Its analysis for June found that companies with fewer than 1,000 employees received 68.2 percent spam volume, compared to 54.6 percent spam received by companies with 1,000 to 2,500 employees.

"Smaller businesses have greater vulnerabilities to threats, both email and Web based, because they invest fewer resources in IT security and have less focus on establishing companywide policies concerning employee email and Web use," said Scott Chasin, chief technology officer, MX Logic.

The company also reported that on average, 0.82 percent of unsolicited commercial email it filtered in June complied with The Controlling the Assault of Non-Solicited Pornography and Marketing (CAN-SPAM) Act, the federal anti-spam law.

Overall, the company found that spam accounted for an average of 74 percent of all email through its threat center in June.
