Data Lake by Telesoft Technologies is a comprehensive data retention system designed for long-term network security, visibility, and threat hunting. It is capable of retaining petabytes worth of network metadata for up to and in excess of one year. Data Lake scales to meet the demands of large networks while maintaining a smaller footprint and lower operational cost. It supports 12+ months of data retention with PB+ storage capability and can ingest over 1.6 million flows per second. The highly scalable architecture ensures compliance with country-specific data retention regulations. Data Lake's architecture enables cost-effective long-term storage with minimal latency for querying year-old data. It uses Hot-Warm architecture to store data in shards, allowing for rapid query results. Data Lake provides access to all data for historical investigation and analysis, regardless of age. It is a distributed system that can easily scale horizontally, enabling the ability to extend and balance large data. Data Lake also allows for the creation of in-depth reports on the data, either manually or automatically triggered based on a range of parameters.
