Shield Exclamation Mark black outline icon

About the Shield Exclamation Mark black outline icon

A rounded heraldic shield drawn in a single even stroke, with a thick tapered exclamation mark and separate round dot centered inside it. The pairing reads instantly as a security warning: a protection layer that has detected a problem. Use it for antivirus and firewall alerts, browser insecure-connection notices, account risk banners, compliance dashboards and admin panels where a protected asset needs attention.

The shield has a wide flat top with small shoulder notches and tapers to a soft point, giving the exclamation plenty of room without crowding the stroke. It sits naturally beside shield check, shield lock and plain warning triangle icons from the same set. At 16-20 px keep the dot separated so the mark stays legible.

This is the black outline version of the shield exclamation mark 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.
