Before you run
A few useful
details.
Portable tools with clear requirements. Here is what to expect when you open your download.
Do I need to install anything?
No installer or separate .NET runtime is needed. Download the EXE and run it on Windows 11 x64. Copperline uses the normal libraries already supplied with Windows; it does not unpack companion DLLs.
Does Copperline include VPN servers?
No. Use a server from your VPN provider, your workplace or your own setup. Configure its profile in Windows first. Connect supports IKEv2 and SSTP; Monitor can observe your Windows VPN profiles.
Do I need both downloads?
No. Each application works independently. Choose Connect to connect and disconnect supported profiles. Choose Monitor if you only want to view profiles, status and connection duration.
How can I verify the downloaded file?
Right-click the EXE, open Properties and check Digital Signatures for Sierra Brumfield. You can also compare the file’s SHA-256 hash with the checksum published in its file details above.
Which language and time settings are used?
The tools use Russian when the Windows interface language is Russian, and English otherwise. Time formatting follows your Windows locale.
Will Monitor change my VPN connection?
No. Monitor is read-only. It displays profile and connection information without connecting, disconnecting or changing your VPN settings.
