Symantec is to extend its online messaging security services offering with the acquisition of MessageLabs for around £410m.
The acquisition of online messaging and web security services firm MessageLabs is expected to be completed by the end of this year.
With MessageLabs, Symantec says it will gain a lead in the rapidly growing software as a service (SaaS) market, and the deal strengthens its position in the messaging security market.
MessageLabs has more than eight million end-users in more than 19,000 organisation, ranging from small businesses to Fortune 500 companies.
Symantec says it will capitalise on cross-selling and up-selling its existing SaaS offerings of back-up, storage and online remote access into the MessageLabs customer base.
Future SaaS offerings, leveraging Symantec technology in data loss prevention, compliance, endpoint security and archiving, will be enhanced by MessageLabs' expertise in SaaS sales, operations and support.
"MessageLabs extends our investments in the software-as-a service segment and will allow us to offer our customers unprecedented choice from a single provider of message security solutions," said John Thompson, chief executive at Symantec.
"By combining MessageLabs with our Symantec Protection Network team, we have one of the strongest portfolios of cloud-based infrastructure services and a great foundation on which to grow," he said.
