Why shield icons work for antivirus products

Shields have been used throughout history as symbols of protection. In digital design, they translate naturally to the concept of cybersecurity: safeguarding data, defending against threats, and providing a promise of safety. For antivirus brands, a shield icon can:

• Represent defense against malware and intrusions
• Communicate reliability and authority
• Act as a recognisable UI element for security features (scans, real-time protection, quarantine)

Overview of the three styles

Each style serves distinct use cases and aesthetic preferences:

• Flat: Bold, minimal, and colorful; great for modern apps and marketing. Uses solid shapes and simple geometry.
• Line (outline): Lightweight and versatile; works well in toolbars, dashboards, and when you need a more subtle UI language.
• Glyph (solid monochrome): Highly legible at small sizes; excellent for system trays, favicons, and compact interfaces.

Design tips for each style

Flat icons

• Use a limited palette (2–3 colors) and high contrast for visibility.
• Keep silhouettes simple so the shield reads clearly at small sizes.
• Use subtle shadows or layering to add depth without complicating the form.

Line icons

• Stick to consistent stroke widths across the set (e.g., 2 px at intended size).
• Ensure rounded stroke caps/joins for a friendly look or miter joins for sharpness.
• Test at small sizes; add minimal internal details to avoid visual clutter.

Glyph icons

• Design at pixel grid sizes (16, 24, 32 px) to ensure crisp rendering.
• Simplify internal elements — glyphs rely on strong negative space.
• Use consistent optical weight so icons feel unified across the set.

---

Accessibility & technical considerations

• Provide clear alt text for each icon (e.g., “Shield with checkmark — Protection active”).
• Use SVG for crisp, scalable icons and ease of styling (color, stroke).
• Provide multiple file formats: SVG, PNG (various sizes), and icon font if needed.
• Ensure sufficient contrast between icon color and background (WCAG guidance).

---

Implementation examples

• Use flat colored shield icons on marketing pages and feature highlights.
• Use line icons within admin dashboards where they need to be subtle and unobtrusive.
• Use glyph icons for system tray, mobile tab bars, or low-resolution contexts.

Example CSS snippet for SVG color swapping:

.icon-shield path { fill: currentColor; } .icon-shield { color: #2b7cff; } .icon-shield--danger { color: #e74c3c; } 

---

Packaging and naming conventions

• Name icons semantically: shield-check.svg, shield-lock-outline.svg, shield-cloud-glyph.svg.
• Organize files into folders by style: /icons/flat/, /icons/line/, /icons/glyph/.
• Include a README with usage examples, licensing, and color tokens.

---

Licensing & distribution

Choose licenses that fit your use case:

• SIL Open Font License or MIT for permissive reuse.
• CC BY-SA if you want attribution and share-alike.
  Include clear attribution instructions if required.
