Sophos has acquired Braintrace, enhancing Sophos’ Adaptive Cybersecurity Ecosystem with Braintrace’s proprietary Network Detection and Response (NDR) technology. Braintrace’s NDR provides deep visibility into network traffic patterns, including encrypted traffic, without the need for Man-in-the-Middle (MitM) decryption. Located in Salt Lake City, Utah, Braintrace launched in 2016 and is privately held.
As part of the acquisition, Braintrace’s developers, data scientists and security analysts have joined Sophos’ global Managed Threat Response (MTR) and Rapid Response teams.
Braintrace’s NDR technology will support Sophos’ MTR and Rapid Response analysts and Extended Detection and Response (XDR) customers through integration into the Adaptive Cybersecurity Ecosystem, which underpins all Sophos products and services. The Braintrace technology will also serve as the launchpad to collect and forward third-party event data from firewalls, proxies, virtual private networks (VPNs), and other sources. These additional layers of visibility and event ingestion will significantly improve threat detection, threat hunting and response to suspicious activity.
Sophos will deploy Braintrace’s NDR technology as a virtual machine, fed from traditional observability points such as a Switched Port Analyzer (SPAN) port or a network Test Access Point (TAP) to inspect both north-south traffic at boundaries or east-west traffic within networks. These deployments help discover threats inside any type of network, including those that remain encrypted, serving as a complement to the decryption capabilities of Sophos Firewall. The technology’s packet and flow engine feeds a variety of machine learning models trained to detect suspicious or malicious network patterns, such as connections to Command and Control (C2) servers, lateral movement and communications with suspicious domains. Since Braintrace built its NDR technology specifically for predictive, passive monitoring, its engine also provides intelligent network packet capture that IT security administrators and threat hunters can use as supporting evidence during investigations. The novel NDR analysis and prediction technique is patent pending.
Sophos plans to introduce Braintrace’s NDR technology for MTR and XDR in the first half of 2022.
