Below is a sample output for an Android smartphone:
The algorithm then assigns a score based on the analysis, providing a clear picture of the system's strengths and weaknesses. This score is presented in a user-friendly format, making it easy for users to understand and take corrective actions.

Most VPN protocols operate at the network layer, so the SYN packet still originates from the VPN server’s TCP stack. Therefore, a VPN connection does normally cause an os_mismatch . However, when combined with other signals (e.g., TLS fingerprints), Zardaxt can still contribute to a multi‑faceted detection system. zardaxt os scoring link
As a result, each OS transmits network packets with a unique combination of default values. Passive tools like Zardaxt do not probe or scan the client. Instead, they quietly read the structural metadata embedded within incoming packets to build a "fingerprint" and compare it against a verified database.
The typically points to its GitHub repository , where the source code and documentation for this tool are maintained. How Does Zardaxt Fingerprinting Work?
Zardaxt also provides a that you can test immediately: Below is a sample output for an Android
Once you have the link, you will typically download a lightweight script or executable that measures frame times and system interrupts.
However, altering browser configurations does not automatically change the behavior of the underlying operating system kernel.

If a client sends an HTTP header claiming to be a Windows 11 desktop computer, but Zardaxt's backend metrics calculate a 95% likelihood for a Linux kernel due to its packet structure, a flag is raised. This mismatch reveals that the client is using a specialized browser tool, a proxy wrapper, or an automated scraping framework. Exploring Zardaxt Metrics Online Therefore, a VPN connection does normally cause an
A key function is to detect if the TCP/IP inferred OS differs from the OS declared in the HTTP User-Agent string, which is crucial for identifying proxies or hidden devices. Applications and Use Cases
