Nanolog uses patented technology to reduce log volume by 10 to 50 times with several compression techniques. Not only does the platform collects and store logs, but it also provides rich real-time analytics capabilities that power a variety of dashboards for customers. Customers are empowered to discover and analyze all their traffic that flows through Zscaler’s distributed proxy network in real-time. The platform also caters to the data mining requirements of Zscaler’s security research team who scour through the mountain of data always on the lookout for new threats emerging on the internet.  The data-mining platform is also purpose-built using map-reduce techniques and exposes a SQL-like query language.
