Trend Micro has acquired Bristol-based email encryption developer Identum.
Identum's Private Post desktop and gateway server products can be used to encrypt messages. The server software will automatically encrypt messages, depending on the user's corporate security policy, and can be used alongside existing email and compliance products.
Trend Micro plans to integrate Identum's software into its existing line of products and rename Identum as Trend Micro (Bristol) Ltd. The company declined to comment on Monday's acquisition, which was announced on Trend Micro's website.
Identum will likely strengthen Trend's software-as-a-service product portfolio, however, because it gives the company a way to add email encryption to its InterScan Messaging Hosted Security product line.
Like other security vendors, Trend has been trying to beef up its software-as-a-service lineup in recent months, offering customers a simpler way to keep on top of the latest threats than is found with traditional security products.
The acquisition will "ensure an even safer, more secure Internet experience for the company's global customers," Trend said.
