Design DNA

Off-white canvas with a faint pastel glow at the top, near-black medium-weight grotesk headings left-aligned, and tiny grey body copy. Each section pairs a two-line heading with a right-hand paragraph, then a wide product surface: a bento of platform tiles (IP map, fingerprint, risk score rings, signal chips), an analytics explorer with a blue bar histogram, rule-builder tables and a JSON API response. Colour appears only in data (blue bars, red and orange score rings, green pills). Three-column hairline-divided spec rows separate blocks.

Worth borrowing

Split each section header into a heading left and a short explainer right on one baseline.
Show a security product through a bento of data fragments: a JSON snippet, score rings and signal chips.
Keep the brand monochrome and let only the data visualisations carry colour.
