About the Wifi Security Padlock black outline icon
Three broadcast arcs rise above a small dot inside a large circle, and a closed padlock sits in its own badge at the lower right. The pairing reads as a protected wireless network, encrypted traffic and password-secured access. Use it in router setup screens, VPN and firewall apps, hotel or cafe network notices, IT security slides, and home network status dashboards.
The arcs widen evenly from the dot, and the padlock badge overlaps the main circle so the two ideas stay linked rather than separate. It pairs with router, shield and key icons. Because the badge carries the meaning, avoid using it below 24 px where the shackle can disappear.
This is the black outline version of the wifi security padlock icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
