About Cyberhaven

Cyberhaven sells a data security platform that traces the full lifecycle of data and adapts protection as context changes, covering data loss prevention, data security posture management, insider risk management and AI security.[1][5][8]

Cyberhaven Flow traces the full lifecycle of data and adapts protection to changing context. Cyberhaven says Flow protects data across human and agentic workflows and connects lineage, identity, and behavior to secure data as it moves across endpoints, browsers, and the cloud. Agentic Data Security, Human Data Security, and DSPM work together in one unified platform.[8]

Data lineage is the technology at the center of the platform. Cyberhaven says its data lineage technology maps the full journey of sensitive data, from creation to every movement, transformation, and fragmentation. Cyberhaven records every event for every piece of data, including every move, copy, edit, and share. Cyberhaven says data lineage traces data from its origin, providing the context used to classify what type of data it is. Cyberhaven says specific types of data start their journey in specific places, such as the customer database in Snowflake or the source code repository in Github. Cyberhaven extracts text content from data and performs optical character recognition (OCR) on images to pull additional text content.[8][9][17]

On the data loss prevention side, Cyberhaven says it combines content analysis with data lineage to reduce false positives. Cyberhaven says it protects data across all exfiltration channels with one product and one policy. Cyberhaven can block exfiltration of sensitive data, educate users, and allow override with justification. Cyberhaven offers a visual builder for creating and editing policies. Cyberhaven lets administrators see how a policy would apply to historical data without deploying it in production. Cyberhaven tracks what type of data was encrypted or compressed, so the data can still be tracked after it can no longer be scanned.[2][10]

For insider risk, Cyberhaven says it combines data awareness and behavioral signals to detect and stop insider threats. Cyberhaven blocks data exfiltration across cloud, email, websites, removable storage devices, Apple AirDrop, and more. Cyberhaven stores a record of events indefinitely and can correlate events occurring weeks or months apart. Cyberhaven scores users on the actions they take and on the type of data affected. Users with a history of risky behavior can be added to a user group that has elevated remediation. Cyberhaven flags when a user changes the extension or name of a file that contains sensitive data and can block subsequent exfiltration. Cyberhaven remotely captures user actions related to data and stores them in its cloud, so investigations do not need physical possession of a device.[2][6][10]

For data posture, Cyberhaven says it discovers and classifies data, detects vulnerabilities as it flows across environments, then secures it automatically. Cyberhaven's data provenance categorizes data as Corporate, Personal, or Public. Cyberhaven reads Microsoft Information Protection labels and other third-party labels. Cyberhaven inspects data stored on user devices, complementing cloud data discovery. Cyberhaven can distinguish between the corporate instance of an approved cloud application and a personal instance of the same application. Cyberhaven detects and tracks usage of new cloud apps employees try to use with company data.[10][12][17]

Cyberhaven tracks what data each agent accesses, what actions it takes, and how sensitive data moves through its workflows. Cyberhaven discovers and monitors Model Context Protocol servers and AI connectors across the enterprise. Cyberhaven gives every AI tool and agent a risk score across five dimensions: data sensitivity, model integrity, compliance adherence, user access controls, and security infrastructure. Cyberhaven enforces runtime guardrails at the prompt and response level, blocking high-risk data movement and redirecting users to sanctioned tools. Cyberhaven says it governs coding agents like Claude Code and Cursor. Linea AI is described as an AI agent that detects and stops the most critical risks to important data, and Linea AI is powered by the Large Lineage Model.[3][6][13][14]

Cyberhaven delivers its service from the cloud, so there are no databases or application servers to manage. Cyberhaven connects to sanctioned applications such as Office 365 and Google Workspace to see content created and shared in the cloud. Cyberhaven's endpoint agent supports Windows, macOS, and Linux. Cyberhaven's browser extension supports all major browsers and collects telemetry for web-based cloud applications. Cyberhaven streams incidents, events, and audit logs into SIEM, SOAR, or AI SOC platforms, with purpose-built integrations for Splunk, Cortex XSOAR, and ServiceNow. Cyberhaven connects to ChatGPT Enterprise and Claude Enterprise directly. Cyberhaven can store incident screenshots, match highlighting excerpts, and other evidence in a cloud bucket the customer owns and controls.[2][9][14][15]

Cyberhaven says it meets internationally recognized standards for security, cloud, and privacy. Cyberhaven provides audit evidence for frameworks like CMMC, HIPAA, PCI, and ISO. Cyberhaven consolidates endpoint agents while coexisting with Microsoft Purview and existing EDR. Cyberhaven analyst services provide a dedicated data protection analyst who continuously tunes the customer's environment. Cyberhaven onboarding services deploy Cyberhaven, integrate it with the customer's environment, and align it to the customer's use cases from day one. Cyberhaven describes a technical account manager who combines deep product expertise with a clear view of the customer's goals.[2][6][8][10][13][14][16][17]
