About Deep Instinct

Deep Instinct sells Data Security X (DSX), a deep learning solution that prevents known and unknown threats across cloud, NAS, applications, and endpoints.[3]

Deep Instinct says DSX prevents and explains zero-day and unknown threats. The company describes its solution as agentless and privacy-first, and says it identifies threats and stops them before they execute. Deep Instinct says DSX secures data at rest and in motion across cloud, NAS, applications, and endpoints.[3][5]

DSX has two named parts. The DSX Brain is described by Deep Instinct as a purpose-built deep learning cybersecurity framework trained on raw data to understand complex attack patterns. Deep Instinct says this allows threat prevention without relying on signatures or heuristics. DSX Companion, called DIANNA, is described as a GenAI engine that provides detailed explainability of zero-day attacks in real time.[3]

Deep Instinct describes several ways to deploy DSX. Cloud storage environments such as S3 and Azure storage can be secured. Network-attached storage is protected with native integration for Dell CAVA and NetApp Vscan. Files transiting through applications are checked with agentless, on-demand scanning. Zero-day protection also extends to user devices.[3][5]

On privacy, Deep Instinct says the DSX Brain operates without cloud connectivity and never sends data outside the customer's environment. The company says its framework only analyzes file hashes and never exports files. Deep Instinct says this helps customers meet regulatory requirements.[6]

Deep Instinct states performance figures for DSX: it says the DSX Brain predicts and blocks more than 99% of unknown attacks in under 20 milliseconds, with under 0.1% false positives. The company also says DSX lowers total cost of ownership, with up to 10x less infrastructure costs.[3]

Deep Instinct says it delivers preemptive data security across diverse environments, from healthcare and financial services to retail, manufacturing, and service providers. The company says dedicated Customer Success Managers and project teams guide deployment, monitor performance, and proactively optimize the customer environment.[4]

Deep Instinct was founded in 2015 by Guy Caspi, Nadav Maman, and Dr Eli David. In 2022, Lane Bess, former CEO of Palo Alto Networks and COO of Zscaler, joined as CEO.[1][3][4]
