Question 1

Is it safe to install on a production server?

Accepted Answer

Yes. The agent only reads its own OS security log and blocks inbound connections to the protected ports on the same host. No offensive capabilities, only outbound HTTPS.

Question 2

Does protection work without a cloud connection?

Accepted Answer

Yes. The ban decision is made locally on the agent instantly, even offline. If the connection drops, protection keeps working from the local policy.

Question 3

What if I changed the RDP port?

Accepted Answer

The agent detects the actual RDP port(s) automatically (registry + listening sockets) and rebuilds the rules on a change. The FTP port is detected the same way.

Question 4

Will I lock myself out?

Accepted Answer

No. On install your current IP is automatically whitelisted, and the whitelist always takes priority over any block.

Question 5

Which Windows versions are supported?

Accepted Answer

Server 2012 R2 / 2016 / 2019 / 2022 / 2025 and Windows 8.1 / 10 / 11, on x64, x86 and ARM64. A single binary, no .NET/VC-redist.

Question 6

How does billing work?

Accepted Answer

Internationally via PayPro Global, in Russia via YooKassa, plus crypto as a fallback channel. Free is perpetual and needs no card.
