About the Security black outline icon
A broad shield with an angled top edge and a pointed base holds a closed padlock at its center, drawn as a rectangular body with a keyhole slot under a tall rounded shackle. The pairing reads as protection, encryption, safe login and verified privacy, so it suits account settings screens, checkout trust badges, antivirus and VPN sites, cybersecurity slide decks and login error states.
The padlock sits slightly above the shield's midpoint so the pointed tip stays visible, and the even stroke weight lets it sit alongside text-sized UI glyphs. It pairs with key, fingerprint and verified check icons. At 16 px drop the keyhole detail and rely on the shield silhouette.
This is the black outline version of the security icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
