- SentinelAIsentinel-ai.comSentinelAI is a browser extension and companion Windows app that leverages AI to analyze web pages and emails for phishing and online threats in real time. It provides instant safety ratings, privacy protection, and customizable alerts for users browsing the web or checking email.
- Agent Sentinelagentsentinel.devAgent Sentinel is a platform that enforces real-time policy, budget, and human oversight for AI agents through a runtime authority layer. It enables organizations to control agent actions, ensuring compliance and safety in automated workflows.
- Sentinelarais.usSentinel is an open source autonomous agent platform built by ARAIS. It is presented as one agent that can handle browser automation, scheduling, coding workflows, and operations tasks, with strong controls and a clean UI. The stack is self hosted and combines a custom Python agent runtime, structured persistent memory, browser automation, a permissions and approval system, and a user interface. Its documented capabilities center on running one agent across several kinds of work. The same Sentinel agent can browse sites, run scheduled checks, write code tasks, and coordinate work. Browser automation is built in through Playwright tools and a live VNC view for visibility. Scheduling uses cron and heartbeat triggers for recurring runs, while memory is described as hierarchical persistent memory across sessions. Controls are a major part of the system. Sentinel includes permission policies, an approvals queue, an audit trail, and estop levels. The interface provides session UI, approvals queue, logs, and operational controls. The documentation also separates Sentinel from araiOS: Sentinel is the agent runtime and user interface, while araiOS is the control plane underneath it, handling modules, permission policies, approvals, platform auth, and coordination APIs. The product is described as a self hosted stack that can be booted quickly. It is open source and licensed under AGPL-3.0. The documentation also refers to installation, a CLI reference, module creation, permissions, Telegram integration, and a multi-instance reference, but the core description remains a single autonomous agent system for teams that need automation with oversight.
- sentinel-ai-auditorpypi.orgsentinel-ai-auditor is a Python package that performs deterministic, offline security auditing of AI agent skills and instruction bundles. It uses static analysis to detect issues such as prompt injection without requiring live model inference. The tool outputs results in SARIF format and is designed for integration into developer workflows and CI/CD pipelines.
- sentinel-simsentinel-sim.comSentinel (SIM) is an AI agent integration and marketplace service that sits between an agent and external services. It presents a unified API for agent tool calls and describes itself as a governed execution and orchestration layer for AI agents. The service says it handles authentication, policy enforcement, budget controls, orchestration, and observability while remaining invisible to the agent. Its documented features include JWT and agent API key authentication, AES-256 credential encryption, brute-force protection, token rotation, and role-based access control. Sentinel also applies per-agent spend limits and alerts, tool and provider restrictions, rate limiting per user or agent, and real-time budget enforcement. For provider routing, it uses one API key to route requests to providers including OpenAI, Anthropic, Gemini, Perplexity, Mistral, Cohere, GitHub, Vercel, Railway, Stripe, Resend, and Replicate. The page also states that it provides cost estimation before execution and a full audit trail on every call. Chain orchestration is part of the product as well. Sentinel supports agent-on-agent execution through sentinel.run(), sequential step chains with output piping, automatic retry and provider failover per step, and budget enforcement that halts chains before overspend. The marketplace section shows preintegrated tools and providers for tasks such as chat, embeddings, image generation, moderation, code generation, deployment, payments, email delivery, and model inference. The page also says there are 21 providers, 234 tools, and 1 SDK. Sentinel is delivered as an SDK available from PyPI or npm, and the setup flow includes signing up on the dashboard, verifying an email, and generating a Sentinel API key. The service says provider credentials are passed per request and are not stored. It is described as free to use. The page includes Docs, Login, Marketplace, and Playground links, but names no company behind the product.

- Sentinelrootstuff.ioSentinel is a website monitoring tool for agencies and freelancers managing multiple client sites. It watches client sites around the clock and sends alerts when downtime, SSL issues, DNS changes, or unreachable hosts are detected, so site problems can be noticed before clients do. Its monitoring features include uptime checks every 30 seconds, SSL monitoring with alerts weeks before expiration, DNS tracking, keyword monitoring for page content or unwanted text, JSON API monitoring, ICMP ping monitoring, TCP port monitoring, heartbeat monitoring for cron jobs and workers, cron job monitoring, and WHOIS domain expiration tracking. The service also includes incident management with automatic timelines and resolution notes, plus public or password-protected status pages with custom domain and branding options. An MCP-based AI assistant feature connects Claude, ChatGPT, or other MCP agents for plain-language incident triage and questions such as whether anything is down. Sentinel supports alerts via Slack, Email, SMS, Discord, and Microsoft Teams. It presents monitoring from a single dashboard and says new monitors can be added by pasting a URL and choosing checks. The page also states that setup takes 60 seconds, that checks can run from 4 global regions, and that team collaboration uses role-based permissions for developers and account managers. Pricing includes a free plan with 10 monitors and a 14-day free trial that can be canceled anytime. Paid plans listed on the page are Starter at $14 per month for 25 monitors, Pro at $29 per month for 100 monitors, and Business at $59 per month for 300 monitors.
