Frequently Asked Questions (FAQ)
- Why should I use the Recommended Options?
They make it easy to use features such as DNS tampering protection and SNI eavesdropping prevention, while maintaining both speed and security. - Does the SNI fragmentation feature slow things down?
No. This program minimizes any slowdown by fragmenting only the SNI string. - Do the DNS settings change the Windows system settings?
No. The program uses its own DNS settings (DNS over HTTPS) without changing Windows settings, keeping your connection stable and secure. - How can I fix it when I can’t access a specific site?
You can minimize access issues by configuring a whitelist or a list of specified domains. - Can I use it without installing it?
Yes. A portable version is available, so you can use it right away without installing anything.
