CIRA DNS Firewall

Block malware & phishing at the DNS layer. Protection on Wi-Fi and cellular.

CIRA DNS Firewall helps organizations block malware, phishing, ransomware, and botnets at the DNS layer- before threats reach your devices. Built for today’s hybrid teams, it keeps protection consistent on Wi-Fi and cellular, on-network or off-network.

This application utilizes Android's VpnService to provide enhanced security and privacy features. The VpnService is employed to establish a local, secure connection on your device, enabling features such as network traffic filtering, ad-blocking, or firewall functionality. It does not route your traffic through remote VPN servers unless explicitly stated as part of a specific feature (e.g., for secure browsing or bypassing geo-restrictions). All traffic processing occurs locally on your device, ensuring your data remains private and secure.
