TCP Fingerprint on Static Proxies

Sometimes the IP alone is not the whole story. We are offering configurable TCP fingerprints on static proxies for users who want traffic to look closer to a specific operating system profile. Windows is the default fingerprint, and you can switch when a different profile makes more sense.

Why TCP fingerprints matter

TCP fingerprinting can reveal traits of the device profile behind a connection. Matching that profile more closely can reduce obvious mismatches between your IP, your tools, and the environment you are trying to emulate.

Choose the profile that fits

• Windows: a broad default for common desktop traffic
• Linux: useful for server-like or desktop automation environments
• Android: a better fit for mobile-oriented traffic patterns
• iOS: helpful when an Apple mobile profile is a closer match

Change the profile, keep the IP

On supported static proxies, you can change the TCP fingerprint without replacing the proxy endpoint itself. That gives you more flexibility while keeping your session setup stable.

Available on static HTTP and SOCKS5 proxies

• HTTP Proxies: easy integration with browsers, tools, and web automation
• SOCKS5 Proxies: flexible support for a wider range of apps and scripts
• Shadowsocks Proxies: encrypted proxy protocol designed for speed and reliability, ideal for bypassing network restrictions while maintaining stable performance
• Trojan Proxies: advanced protocol that mimics regular HTTPS traffic, offering strong resistance to DPI and improved stealth in restrictive networks

Where this helps

• Automation that needs a more consistent OS profile
• Testing flows that behave differently on desktop and mobile
• Account setups where protocol-level details matter
