How this page is organised

Categories are the primary structure of the AmbiSecure engineering blog. Each post is filed under every subject area it substantially covers, so a category page is the closest thing we have to a reading list for that topic — open one and you get the full body of writing on it, newest first.

Each card below shows a split count, and the dates matter when deciding what to read:

• Recent posts are current engineering writing — the architecture, trade-offs, and implementation detail we stand behind today.
• Earlier posts are kept online because the background material is still sound. Each carries its original publication date and links forward to current coverage wherever a newer post supersedes it.

A topic whose posts are all several years old is a subject we wrote about before the current blog and have not revisited yet — those posts are still the best starting point there. Topics with a large recent count — FIDO, Cyber Resilience, Smart Cards, Transit — are where the current engineering work sits.

For cross-cutting topics that span several categories, use tags instead; for a specific term or part number, search the blog. To read straight through in date order rather than by topic, start at page 1 of the blog and continue to page 2, then the topic index.
