Zscaler SIEM integration

“Zscaler NSS enables large enterprises to filter and correlate global log data into the organisation’s SIEM in real-time,” said Manoj Apte, senior vice president of product management, Zscaler. “Unlike security appliances that provide syslog, Zscaler’s Nanolog technology correlates transactions from around the world across multiple dimensions every second. This enables enterprise to filter and feed exact events that they care about into their SIEMs rather than investing in a massive logging infrastructure.”

Typical large organisations generate more than 20GB of log data every day, yet struggle to obtain a complete view across complex and distributed cloud and mobile environments, making it difficult to analyse traffic patterns for anomalies and security vulnerabilities. Additionally, it is nearly impossible for SIEM solutions to integrate the volume and flow of this data from multiple sources without additional investment in professional services to develop point integrations. Despite this, many organisations are faced with compliance regulations that require this data to be stored locally for future audit and analysis.

“The value of ‘big data’ is only as great as our ability to correlate, analyse and understand it,” said Bobby Clarke, Information Assurance Manager, Sealed Air. “Working with Zscaler NSS enables us to easily integrate, archive and investigate our security data with SIEM solutions to provide actionable intelligence.”

Zscaler NSS automates the real-time integration of its comprehensive log data into leading SIEM solutions from HP ArcSight, IBM QRadar, and Splunk without requiring administrators to understand each complex integration format. As log data is generated by all users, across all devices and locations, Zscaler NSS easily streams compatible data into the SIEM in real time.

"Many organisations are struggling to get visibility of user activity and behavior in the cloud. ZScaler NSS is an important information stream for SIEM solutions and delivers in-depth visibility of user and threat activity within the cloud," said Jason Corbin, director, security intelligence strategy and product management, IBM. "Combined with QRadar's ability to analyse all the other security, application, network activity, user and vulnerability data within an organisation, the Zscaler NSS feed adds yet more context around security threats such as malware or out of policy behavior in the cloud. This enhances QRadar's ability to deliver highly prioritised incidents to its users."

Zscaler NSS is a flexible and customisable solution, capable of integrating multiple streams of logs into different SIEMS and pre-processing logs to filter relevant sub-sets of data. Zscaler complements the deep data analysis capabilities of SIEM solutions by providing a comprehensive view into user activity on any device in any location.
