Design a real App Store or Google Play icon for the App Type. Center the single Symbol as a strong, simple silhouette with generous padding inside the central 80 percent, readable at 60 pixels. Render the Variant in the Style using the Color Palette, with one consistent light direction from above. For this gradient treatment, use a smooth two-tone dark slate background and a flat white glyph with clean, precise edges. Keep the canvas perfectly square at 1:1, filling the entire 1024x1024 frame edge to edge. Use no text, letters, device frame, rounded-corner mask, external border, outside shadow, busy detail, glow, sparkle, lens flare, watermark or resemblance to an existing app icon or brand logo.
Use these details:
App Type: "VPN app"
Symbol: "white shield glyph with a centered keyhole"
Style: "Gradient icon"
Color Palette: "dark slate gradient with white glyph"
Variant: "Standard light icon"

Your result will come out close to the example rather than identical to it. Change the details to make it yours.
