Sentinel is a security platform designed to protect AI agents from prompt injection attacks and secret leaks before they reach large language models (LLMs). It addresses vulnerabilities in AI agents that process external content, where attackers may embed hidden instructions or attempt to bypass filters using encoding or fragmented attacks. Sentinel provides a multi-layered defense system specifically tailored to the challenges faced by AI agents operating in production environments. The platform incorporates four core layers of defense: content scanning, runtime detection, secret scanning, and continuously updated threat intelligence. Content scanning examines incoming data for hidden HTML, encoded payloads, instruction patterns, and fragmented attacks before they reach the LLM. Runtime detection monitors agent behavior during execution, identifying abnormal output patterns, privilege escalation attempts, and context hijacking. Secret scanning inspects outbound agent content in real time to prevent accidental exposure of API keys, tokens, AWS credentials, database URIs, and private keys. The system’s threat intelligence is continuously updated by a dedicated security team, ensuring new detection rules are shipped with every release to counter emerging attack techniques. Sentinel supports multi-format scanning, detecting threats in HTML, Markdown, JSON, plain text, and various encoded formats such as base64 and hex. It features evasion-resistant capabilities, including detection of developer mode jailbreaks, leetspeak obfuscation, and filler word insertion attacks. The tool is optimized for sub-second detection speeds suitable for production use, and maintains a block history log for all intercepted threats. Sentinel includes a system prompt auditor that assesses agent prompts for injection vulnerabilities and provides structured risk reports with actionable recommendations. Integration with popular AI agent frameworks is facilitated through middleware adapters for LangChain, CrewAI, Haystack, and AutoGen/AG2, allowing users to add Sentinel’s protection with minimal code changes. The platform runs locally on the user’s infrastructure, ensuring that data such as prompts, documents, and agent conversations never leave the machine. Sentinel is available with self-serve pricing starting at £5 per month, and detection rules are delivered encrypted and signed, auto-refreshed in the background to maintain up-to-date protection.
mac-manager is an open-source command-line tool that allows macOS users to monitor their device's health, security status, and hardware directly from the terminal. It provides battery alerts, a live dashboard, security audits, and developer tooling inventory, making it ideal for developers and power users who want detailed system insights without a GUI.
Minimal repository scanning CLI.
