The U.S. Patent and Trademark office gave the okay to Tumbleweed’s latest patent application—bringing the email-security company’s total to 29—for a technology it calls “the email firewall.” The new patent describes “the enforcement of multiple administrator-selected policies to email traffic entering or leaving an organization.
Earlier this month, Tumbleweed announced the availability of it FTP Analyzer, which allows customers to gain visibility into File Transfer Protocol (FTP) traffic, including rogue FTP traffic.
“Many organizations are unaware that substantial amounts of business-critical data are entering and leaving their network via unsecure or rouge FTP servers, leaving them vulnerable to data breaches,” the company says in a press release. “As file sizes have grown and email attachment sizes have continued to be limited, employees have increasingly turned to FTP for the transmission of files in business interactions. As a result, FTP has emerged as a new security-attack vector. [A]nd a wave of high-profile data breaches, as well as reports of organized criminal activity, has stemmed from vulnerabilities in susceptible FTP servers.”
