## ContextFort：安全的浏览器代理管理 ContextFort 增强了团队使用 CometAtlas 和 Claude 等浏览器代理的安全性。它提供对代理活动的**可见性**——跟踪会话控制、页面访问、点击和文本输入——从而清晰了解代理正在做什么。除了观察，ContextFort 还提供强大的**控制**。安全团队可以主动**阻止特定页面上的操作**（例如，防止表单提交）并**缓解风险较高的跨站点交互**（例如，阻止在敏感平台之间的导航）。策略可以定制，以完全限制外部上下文共享。 ContextFort 以浏览器扩展的形式提供，并获得 YCombinator 的支持，提供标准部署以及企业级云/自托管管理选项。它使安全团队能够自信地利用浏览器代理，同时保持强大的控制并最大程度地降低风险。

ContextFort (contextfort.ai) 是一款开源浏览器扩展，旨在提供对类似Claude的AI浏览器代理的可见性和控制。这些代理能够自主浏览和与网站交互，在传统搜索或API无法满足需求时非常有用。然而，企业采用受到安全问题的阻碍，特别是间接提示注入的风险。ContextFort通过跟踪代理会话（记录访问过的页面和用户交互）来解决这个问题，为安全团队提供关于代理使用的关键洞察。除了可见性之外，ContextFort还允许团队实施控制措施，例如阻止在特定页面上的特定操作，或防止危险的跨站点数据流。演示视频地址：[https://www.youtube.com/watch?v=1YtEGVZKMeo](https://www.youtube.com/watch?v=1YtEGVZKMeo)，扩展程序可在GitHub上找到：[https://github.com/ContextFort-AI/ContextFort](https://github.com/ContextFort-AI/ContextFort)。该扩展程序与Chrome上的Claude扩展程序共享权限，网络请求最少，仅用于使用情况分析（PostHog），并且可以禁用。

How it works

ContextFort provides security teams with Visibility into agent sessions

When control is handed over
Which pages the agent visits during a session
What it does on each page (what was clicked and where text was input)

ContextFort also offers Controls for security teams to act on based on what the visibility layer captures

Block specific actions on specific pages (e.g., prevent the agent from clicking "Submit" on email)
Block risky cross-site flows in a single session (e.g., block navigation to Atlassian after interacting with StackOverflow), or apply a stricter policy and block bringing any external context to Atlassian entirely

If you need cloud/self-hosted management for an enterprise deployment, contact us.
