AI Agent Security Guardian for macOS — monitors system health and AI agent behavior (file access, network connections, risky commands) with smart alerts

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.

Sentinel SIM is a governed execution and orchestration layer designed for AI agents, providing a unified API that allows agents to interact with a wide array of external services and providers. By acting as an intermediary, Sentinel manages authentication, policy enforcement, budget controls, orchestration, and observability for agent tool calls, streamlining integration and management across multiple providers. The platform is positioned as a solution for developers and organizations seeking to route, monitor, and control agent interactions with external APIs and tools while maintaining security and compliance. Key features include JWT and agent API key authentication, AES-256 credential encryption, brute-force protection, token rotation, and role-based access control. Sentinel enforces per-agent spend limits and alerts, tool and provider restrictions, rate limiting, and real-time budget enforcement. It provides provider routing through a single API key, supporting integrations with providers such as OpenAI, Anthropic, Gemini, Perplexity, Mistral, Cohere, GitHub, Vercel, Railway, Stripe, Resend, and Replicate. The platform offers cost estimation before execution and maintains a full audit trail for every agent call. Chain orchestration capabilities enable agent-on-agent execution, sequential step chaining with output piping, automatic retries, provider failover, and budget enforcement that halts chains before overspending occurs. Sentinel SIM is delivered as an SDK available for installation via PyPI or npm. Users sign up on the dashboard, verify their email, and generate a Sentinel API key to begin routing tool calls through the platform. Provider credentials are passed per request and are not stored by Sentinel, ensuring that users retain control over their keys. The platform automates authentication, policy checks, budget enforcement, provider routing, observability, and auditing for each call. Sentinel SIM's marketplace offers pre-integrated tools and providers, allowing agents to perform a variety of tasks such as chat, code generation, deployment, payments, email delivery, and machine learning model inference, all governed by Sentinel's orchestration and security framework.

Sentinel is an open source autonomous agent platform designed to handle a range of tasks including browser automation, scheduling, coding workflows, and operations tasks. 0, Sentinel brings together a custom Python agent runtime, structured persistent memory, and a permissions and approval system within a self-hosted stack that can be quickly deployed. The platform enables a single agent to manage diverse workflows, such as browsing websites, running scheduled checks, executing code-related tasks, and coordinating operational work. Sentinel features built-in browser automation using Playwright tools, and provides a live VNC view for visibility into automated browser sessions. For scheduling, it supports cron and heartbeat triggers, allowing for recurring task execution. The persistent memory system is hierarchical, maintaining state and data across multiple sessions. Strong controls are central to Sentinel's design. It offers detailed permission policies, an approvals queue, an audit trail, and multiple emergency stop levels. The user interface includes session management, logs, and operational controls, supporting oversight and transparency for ongoing agent activities. Sentinel operates alongside araiOS, which functions as the control plane, handling modules, permission policies, approvals, platform authentication, and coordination APIs. While Sentinel runs the agent logic and user interface, araiOS governs access and action controls. Sentinel is positioned as a solution for teams seeking a self-hosted, extensible agent capable of automating complex workflows with robust governance and oversight features. Its open source licensing allows for customization and deployment within a variety of organizational environments.
