The Deep Content Control technology will allow organisations to protect against leaks of sensitive and confidential information from a variety of sources.
These include poor security practices, ill-advised business processes, insider attacks and targeted external attacks, and can result in loss of intellectual property, compliance violations and harm to brand reputation.
Websense has signed an agreement to imbed PortAuthority's PreciseID information classification and identification technology into its Security Suite to act as a "digital data guardian".
This provides a unified policy management console to control what data users can send and to whom.
"It is not about catching people after they've done it. It is about preventing it from happening in the first place."
For example, a business could identify and prevent an employee from accidentally or maliciously sending customer credit card data, sales projections or product source code to a non-trusted or unknown location or unauthorised internal recipient.
"With PortAuthority, we gain accurate and advanced information fingerprinting and identification technology, a critical feature for our customers looking for a leak prevention solution," said Gene Hodges, chief executive of Websense.
Market research firm IDC predicts that sales of multi-protocol content filtering technologies will grow from $194m in 2007 to $434.6m in 2009.
Filtering outgoing content will become a feature built-in to switches from the major vendors, Stiennon predicted.
"We are starting to see that now, but you won't see widespread adoption until [outgoing content filtering] is a tick-box item, say in about 18 months," he said.
