URL shortening service Bit.ly has partnered with security firms to improve its anti-spam and malware protection. VeriSign, Websense, and Sophos are the companies that will help Bit.ly.
VeriSign’s iDefense IP will screen links to prevent them from pointing to blacklisted sites. Websense’ Threatseeker cloud service will detect URLs to check whether they are spamvertised or malicious sites. A behavioral-analysis technology will be provided by Sophos. This technology will proactively detect spam and malware.
According to Websense, over two billion shortened URLs were created just two months ago.
