Hi Product Hunt! I'm 云遮天, the maker of Port Sentinel.
Who is connecting to your Windows PC, which ports are they reaching, and how often are they coming back? Port Sentinel brings those details into one desktop interface.
You can:
• Watch inbound TCP/UDP activity and available RDP authentication events.
• Search connection history and compare activity by source IP.
• Configure manual or frequency-based IP blocks, timed removal, and allow/block lists.
• Explore source locations with an offline IP database and a world-map dashboard.
• Manage local logs with retention controls and backups, while the app runs in the system tray.
The dashboard shows events received by your computer—not an Internet-wide attack feed. A connection attempt is not automatically malicious, and IP locations are approximate.
It runs on Windows 10/11 x64 and requires administrator permission. The UI is currently in Simplified Chinese, with Chinese and English documentation.
What would make this more useful for your workflow: better filters, more reporting options, or an English UI? I'd love to hear your feedback.

大家好，我是 Port Sentinel（端口监测）的作者云遮天。
谁在连接你的 Windows 电脑？访问了哪些端口？同一个 IP 尝试了多少次？Port Sentinel 将这些信息集中在一个桌面界面中。
你可以实时查看 TCP/UDP 入站活动及可用的 RDP 认证事件，检索连接历史、比较来源 IP 的访问次数，配置手动或基于访问频率的自动封禁，并使用黑白名单和限时解除。
软件还提供离线 IP 地理位置、全球来源地图、日志保留与备份，以及系统托盘运行。
大屏展示的是本机收到的事件，不是整个互联网的攻击情报；连接尝试不一定是恶意行为，地理位置也只是近似结果。
支持 Windows 10/11 x64，需要管理员权限。目前界面为简体中文，提供中英双语文档。
欢迎告诉我你最需要哪些改进：更灵活的筛选、更多报表，还是英文界面？
