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 Constellation Gate AI?

Constellation Gate AI acts as a supplementary defense layer for AI agents, strategically placed between the agent and the model to scrutinize all requests for possible risks and data breaches. This innovative solution operates as an inline gateway for coding agents and model APIs, safeguarding workflows without requiring extensive code alterations. Users can seamlessly direct their existing tools such as Claude Code, Cursor, OpenClaw, Codex, or OpenCode to engage with Gate, thereby securing defenses against prompt injection, secret exposure, PII redaction, token optimization, and maintaining a trustworthy audit trail. The platform effectively tackles three significant vulnerabilities: prompt injection attacks, unauthorized access to credentials and PII, and illicit tool activations. Instead of relying solely on the model's built-in defenses, Gate proactively intercepts potential attacks before they reach the model, eliminates sensitive data from responses before they are returned, and blocks outputs from compromised tools before agents can utilize them. Gate remains compatible with the standard calls made by agents, forwarding them to the model while thoroughly analyzing each request and response in both directions, thereby providing robust protection against evolving threats. This forward-thinking strategy not only bolsters security but also cultivates user confidence in the reliability and safety of their AI operations, ultimately fostering a more secure environment for innovation.
