Cloud-based compliance and data-security provider Trustwave soon will add Web security to its portfolio through the acquisition of M86 Security, an Irvine, Calif.-based provider of advanced antimalware technology.

Trustwave did not disclose financial details of the acquisition, which it expects to close in about three weeks. The acquisition, announced Wednesday, is a way to protect its customers from the more than 90% of all malware that is delivered through the Web, Trustwave says.

"By acquiring M86 Security, Trustwave is adding Web security to one of the industry's most comprehensive security product portfolios, including our compliance, application, network and data security solutions," said Robert J. McCullen, Trustwave's chairman chief executive and president, in the release. "Customers and partners will benefit from our simplified approach to delivering advanced antimalware technology through the cloud and our managed services."

Trustwave, of Chicago, warns that even "good" websites, including social networks and news sites, can serve up malware designed to compromise users' computers and steal data.

Additionally, the majority of email threats now come from links to malicious websites instead of through attachments, Trustwave stated.

With the acquisition, Trustwave gains various Web and email security products, advanced malware technology, new cloud-based technology to add to its TrustKeeper portal, and broader threat intelligence and security research, the company outlined. In addition, Trustwave plans to add the M86 Secure Web Gateway to its Trustwave Managed Security Services.

Last month, Trustwave announced a Web-access security service based on firewall protection software (see story). The acquisition of M86 Security will allow Trustwave to go much deeper into Web gateway and content security, the company stated.

The acquisition also bolsters Trustwave's international presence, particularly in Europe, the Middle East, Africa and Asia, the company added.

Both Trustwave and M86 Security are privately held companies.
