What is Proofpoint AI Security?

Proofpoint AI Security is a comprehensive solution designed to support organizations in overseeing, monitoring, and protecting the implementation of AI technologies, such as large language models and autonomous agents. This platform provides visibility into both sanctioned and unsanctioned AI activities, enabling security teams to detect unauthorized AI tools, monitor prompts and responses, and evaluate AI interactions with confidential data in real-time. By leveraging intent-based detection and behavioral analysis, it efficiently identifies anomalies, prompt injection attempts, and potentially harmful interactions, while also enforcing operational policies to prevent data breaches and misuse. Additionally, it reconstructs detailed AI transactions from the user's initial query to the subsequent actions and outcomes generated by the agents, ensuring that organizations retain full traceability and are ready for audits. Its functionalities encompass endpoints, web browsers, and AI agent links, promoting stringent access governance that ensures AI systems only utilize and share necessary information. This comprehensive control not only strengthens the enterprise's security posture but also fosters a proactive approach as organizations adapt to the evolving landscape of AI system integration, creating a safer digital environment overall.

What is Knostic?

Knostic serves as an all-encompassing platform dedicated to the security and governance of enterprise AI, designed to prevent data leaks and control how large language models handle and share information within organizational settings. It utilizes a "need-to-know" access control system that dynamically determines the extent of data an AI can reveal based on the user's role, the situation, and their objectives, moving beyond traditional file permission methods. By emphasizing the knowledge layer that lies between raw data and AI-generated results, it carefully examines how information is inferred, aggregated, and displayed to ensure that sensitive content is not inadvertently disclosed. Additionally, Knostic maintains continuous oversight of AI activities across a range of applications, including tools like Copilot and other language model-driven assistants, while identifying potential risks such as semantic oversharing, inference-based exposure, and unauthorized access to sensitive information. It also conducts practical prompt simulations to uncover hidden vulnerabilities before they are put into action, assigns quantitative risk scores, and enables organizations to implement comprehensive policies effectively. By combining proactive risk evaluation with continuous governance, Knostic not only enhances corporate security but also plays a crucial role in maintaining trust and integrity as AI technologies continue to evolve and integrate into various business processes.
