EMC acquires NetWitness

On the heels of a security breach that shook RSA's customers, parent company EMC announces its acquisition of network security analysis vendor NetWitness.

In an email this morning, EMC said its acquisition of NetWitness closed Friday. NetWitness will now operate as a part of RSA, the security division of EMC.

The timing of this news is interesting, coming just a few weeks after RSA announced hackers penetrated RSA servers and stole information related to the company's SecurID two-factor authentication products.

As for the NetWitness purchase, EMC had this to say in its press release:

"The intensity and sophistication of advanced adversaries and zero day malware challenge every organization to rethink traditional approaches to network security," said Tom Heiser, President, RSA, The Security Division of EMC."NetWitness has redefined the security landscape, providing a powerful solution for organizations seeking to gain immediate insight, precise clarity, and timely closure in the face of the toughest cyber threats. NetWitness' unique network security analysis capabilities extend RSA's solutions for managing security risk and compliance across both physical and virtual environments."

NetWitness will become a core element of RSA's Advanced Security Management Solutions, providing real-time visibility into network activity and adding efficiency to incident investigations and workflow.--Bill Brenner
