Security software vendor Webroot plans to buy Email Systems, a provider of email and web protection services.
The acquisition will give Webroot a new line of software-as-a-service (SaaS) products to complement its existing security software. Webroot sells a popular anti-spyware program called Spy Sweeper.
Email Systems sells email, web and data archiving management services.
Following the acquisition, Webroot will sell Email Systems' web-based services under the brand name Webroot Email Security SaaS.
"Webroot Email Security SaaS will be an important piece to the layered security approach by offering levels of network protection beyond what an on-premise solution can provide," a Webroot spokesman says.
