CYRONIX FIREWALL.
KERNEL-LEVEL ISOLATION.
Direct Linux Netfilter packet filtering enforced inside the kernel network stack. Controls per-app Wi-Fi and mobile connectivity without proxying traffic or occupying Android's VPN slot.
True Hardware-Level Speed
Traditional Android firewalls run a local pseudo-VPN daemon that routes all packets through user space, causing thermal throttling, latency spikes, and battery drain. CYRONIX executes directly in the kernel network subsystem.
Granular Wi-Fi & Cellular
Every application possesses an isolated Linux UID. CYRONIX Netd assigns rules matching UID socket descriptors, allowing complete disconnection of calculator, notes, or gallery apps from outbound network access.
Private DNS over TLS (DoT)
All DNS lookups are strictly encrypted using TLS on port 853. Unencrypted port 53 UDP/TCP fallbacks are rejected, preventing ISP eavesdropping, rogue hotspot sniffing, and carrier DNS hijacking.
How Kernel Packet Filtering Works
When an application attempts an outbound socket connection, the packet passes through the Netfilter OUTPUT chain. The kernel module xt_owner checks the sender's UID against the active Cyronix firewall table:
