This is a Security SSL icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,600 icons, all in the same style and quality.
It is an emblem or a shield with the letters SSL inside of it right in the middle of the shield. There are four total points on the shield, one at the bottom, two on the top left and top right corner and then one rounded point slightly above the two corners.
