GCSA HomeGuard

GCSA Home Guard is a network and device safety self-check tool that helps you understand your current network environment and identify common risk signals. Key features: • Network Information: View your public IP, provider/ASN, estimated network-egress location, and DNS and WebRTC diagnostic signals. • Home Devices: With permission, discover visible devices on the current local network and review limited, explainable device and service clues. • Nearby Bluetooth: With permission, view nearby Bluetooth signals and explainable risk hints. • Financial Safety: Check suspicious or impersonation domains and analyze supported public blockchain wallet addresses that you choose to submit. Privacy: Local-network scan results, SSID/BSSID, device hostnames, and Bluetooth identifiers are processed and displayed on device by default and are not uploaded. Public IP addresses you actively query may be sent to ip.gcsa.org for ASN, network-provider, and approximate-region lookup. Supported public cryptocurrency wallet addresses you actively submit may be sent to chainscan.gcsa.org for risk analysis. The app never asks for or uploads wallet private keys, seed phrases, or clipboard secrets. GCSA Home Guard is not a VPN, proxy, MDM, antivirus, or cross-region traffic relay and does not replace a professional security audit. Results may vary with iOS permissions, network conditions, and device responses.
