About Jazz

Jazz traces activity across four dimensions of context: data, systems, people and business. Jazz names GenAI, desktop activity, and homegrown or shadow apps as creating invisible data loss vectors.[1][3][4]

Jazz's AI forensic endpoint agent captures every meaningful data-handling action on the endpoint. Jazz collects forensic data and stores it in an encrypted, rolling buffer on the endpoint. Jazz's agent streams lightweight metadata about data movements to the Jazz cloud, creating a real-time map of data activity across apps, accounts and devices. Jazz's agent sees data handling events such as copy/paste, screenshots, GenAI prompts, screen sharing and file uploads at the operating system level.[5]

Jazz's agent has visibility across desktop applications, browsers, CLI tools, sanctioned SaaS, shadow IT and personal cloud accounts without requiring per-app integrations. Jazz's agent covers copy and paste, screenshots, GenAI prompts, screen sharing and file uploads on managed Windows and macOS laptops, in any browser or desktop app. Jazz's OS-level agent needs no browser extension. Jazz works at the user-space level, capturing clipboard activity, screenshots, file movements and application interactions.[5][6][7]

Jazz's agentic investigator analyzes every suspicious activity and reconstructs the full story. Melody considers the full context of every data event. Jazz's agentic investigator, Melody, analyzes every event to deliver pre-investigated answers and proactively suggests policy improvements. Melody automates policy creation on the fly. Jazz lets users manage and optimize a DLP program in plain English.[3][4][8][9][10]

Jazz connects data, systems, people, business processes and exfiltration vectors to create a dynamic map of how information travels through an organization. Jazz connects insights across thousands of events to uncover patterns, risky behaviors and systemic exposures across an environment.[3][9]

For prevention, Jazz gives nudges, requests justifications and applies precise blocks when needed. When an action is unexpected or potentially risky, Jazz asks the user for a quick explanation before the action moves forward. When activity is low-risk but still questionable, Jazz might steer the user toward a safer path. When an action is highly sensitive or requires added oversight, Jazz flags it to a manager or security analyst before allowing it. When activity clearly puts sensitive data at risk, Jazz prevents it from happening. Jazz gives granular control over what is monitored, investigated, retained and presented to analysts.[1][2][4][8][9][10][12]
