Networking equipment giant Cisco Systems said today it has reached a deal to pay $453 million for Lancope, a privately held security company based in Georgia.
Lancope specializes in analyzing the flow of traffic across networks to look for breaches. Broadly speaking, unusual activity on a network that doesn’t fit typical patterns can often trigger warnings that an attack is under way or that a system somewhere on the network has been compromised.
Cisco and Lancope have been partners for a while. Cisco has resold Lancope’s Stealthwatch product as part of its security portfolio for a few years.
Lancope is also the third security firm Cisco has acquired this year. In addition to Lancope and OpenDNS, it last month scooped up Portcullis, a U.K.-based security consulting firm.
