Microsoft has expanded its enterprise security options.
It is buying web-filtering software from FutureSoft, and has released a public beta of the next version of its firewall and virtual private network product, Internet Security and Acceleration (ISA) Server 2006.
The company has also released a limited customer beta for both its Microsoft Client Protection and Microsoft Antigen for Exchange security products.
The beta for ISA Sever 2006 can be downloaded from Microsoft's website. The company has not revealed how many customers are taking part in the Client Protection and Antigen for Exchange betas.
Microsoft has bought the DynaComm i:filter solution from privately-held FutureSoft, which will remain an independent company following the deal.
The solution allows IT administrators to filter content coming through a company's network that is deemed inappropriate. The software can also protect users against spyware, by blocking any download of executable files through web browsers.
New features in the Microsoft's ISA Server 2006 beta include increased security for web application servers and management tools that simplify the process of deploying ISA Server 2006 in branch offices.
