Veritas Shield is our in-tunnel DNS security layer (always on while connected on Android and Linux). Lookups go to 10.0.0.1, then over DNS-over-HTTPS for names we allow. Refreshed feeds can NXDOMAIN malware, phishing, scam, cryptomining, and tracker hostnames; ads stay off unless you pick the Aggressive preset (Security / Standard / Aggressive in the app). Ordinary DNS, DNS-over-TLS, and well-known public DoH resolvers are blocked so apps cannot easily bypass Shield; uncommon custom DoH remains a residual risk. Upstream resolvers still see hostnames we forward. Blocked counts in the app are per tunnel IP for the session—not your public WAN IP. This is DNS filtering, not antivirus.
