04 Usage Rules

Follow these guidelines to maintain brand consistency across all touchpoints.

✓ Do

  • Use "Sentinel Security Agent" or "Sentinel" as the product name
  • Place the logo on dark backgrounds (#0A0A1A or #1A1A2E) for best contrast
  • Maintain the 1x clear space around the logo at all times
  • Use the shield icon alone for favicons and small-format placements
  • Use Inter for all text elements in marketing materials
  • Use the cyan-to-teal gradient for the shield icon
  • Pair the logo with a dark surface when overlaying on images

✗ Don't

  • Abbreviate to "SSS" or "SA" in external communications
  • Rotate, skew, or distort the logo or wordmark
  • Change the shield icon color outside the approved gradient
  • Place the logo on busy or low-contrast backgrounds
  • Use the logo at sizes smaller than 120px width (digital) or 30mm (print)
  • Add effects like drop shadows, outlines, or glows to the logo
  • Combine the Sentinel logo with other brand logos in a lockup
