Mac

Shield Security gives your Mac the network privacy it deserves. One purchase. No subscription. No server. No cloud. Everything runs on your Mac. DNS ENCRYPTION Every website you visit starts with a DNS query your internet provider can read. Shield Security encrypts every DNS query using DNS-over-HTTPS or DNS-over-TLS through your choice of six trusted providers: Cloudflare, Google, Quad9, AdGuard DNS, Cloudflare Family, or NextDNS. Your ISP sees nothing. Setup is one tap. Providers like AdGuard DNS, Quad9, and Cloudflare Family also block known malicious and tracking domains at the DNS level — across every app on your Mac, not just your browser. NETWORK CONNECTION MONITOR See every established outbound TCP connection your Mac is making, updated every 10 seconds. Filter by risk level. Search by hostname. Private and local ranges are excluded so you only see connections that matter. The connection log also cross-references active connections against a reference list of suspicious IP ranges and unusual ports — flagging anything worth investigating. Every entry reflects a real, live connection on your Mac. WI-FI SECURITY SCANNER Joining a coffee shop or hotel network? Shield instantly analyses it for: * Open networks with no encryption * Outdated WEP encryption (cryptographically broken) * Weak first-generation WPA * DNS resolution integrity (checks for hijacking) * Signal anomalies that may suggest a rogue access point A clear Safe / Warning / Danger indicator tells you whether to proceed. PRIVACY AUDIT Find out which apps on your Mac declare access to your camera, microphone, location, contacts, screen recording, accessibility controls, and keyboard input. High-risk apps are flagged clearly. Tap any app to read the exact reason it declared each permission. IP INFO & PORT SCANNER See your real public IP address, ISP, city, and ASN — exactly what every website sees when you visit. The built-in port scanner checks 15 common ports on your local router and flags any exposed services that could be exploited. LIVE SECURITY SCORE A score from 0 to 100 reflects your real protection state: DNS encryption status, Wi-Fi security, suspicious connection findings, app permission exposure, and open router ports. The menu bar icon updates in real time. WHY SHIELD SECURITY * One purchase — no monthly fee, ever * No account required — works the moment you download * Zero data collection — all analysis runs locally on your Mac * No VPN tunnel to configure or subscribe to * No file scanning — network monitoring only * Transparent about what each feature does and its limits Built with Apple's own frameworks: NetworkExtension, CoreWLAN, NWPathMonitor, NSWorkspace, NWConnection. No private APIs.
