What is Data Loss Prevention Software in Japan?

Data loss prevention (DLP) software is designed to protect sensitive information from being accidentally or maliciously exposed, shared, or lost. It monitors and controls data transfer across endpoints, networks, and storage systems to prevent unauthorized access or leaks. DLP tools can detect patterns, keywords, and encryption to identify and block the movement of confidential data, such as financial records or personal information. The software often integrates with email systems, cloud storage, and file-sharing platforms to enforce security policies. By preventing data breaches and ensuring compliance with regulations like GDPR and HIPAA, DLP software helps safeguard an organization's valuable data assets.

    Plurilock AI PromptGuard

    Plurilock AI PromptGuard

    Plurilock Security

    Plurilock AI PromptGuard is a new, patent-pending security tool designed to protect companies against data leaks while their employees use generative AI platforms like ChatGPT. Unlike other solutions to the generative AI data leakage problem, PromptGuard doesn't block AI use or individual AI prompts. Instead, PromptGuard relies on a mature DLP engine to detect sensitive data in prompts and anonymize it before it is sent to the AI platform. When the AI platform returns an answer, PromptGuard restores the original references before showing them to the user. This preserves the workflow and query flow of AI, enabling users to productively use it, while keeping sensitive data out of the AI platform's hands. PromptGuard also provides a complete, bi-directional audit log of queries and replies for each user, enabling companies to create a compliance-friendly record of what was sent to AI, and what AI sent back.
