Security appliance maker Barracuda Networks has acquired Purewire, a Web security-as-a-service provider, the companies were set to announce on Tuesday.
The acquisition gives Barracuda the SaaS offering, but also adds to its security researcher and threat detection capabilities, the company said.
The companies did not disclose terms of the deal.
Barracuda offers e-mail, Internet, Web, and instant messaging protection, much of it based on open-source software.
Purewire launched its Trust Web reputation service earlier this year.
