How we rank Duo Security alternatives
Ranking is quality-first. We sort by customer migration data (when businesses cancel Duo Security in Claros and specify a replacement, that pair gets tracked), then capability overlap (derived from our structured capability taxonomy across 260+ tools), then buyer fit (ideal customer profile, pricing model, sales process). Among close matches of similar quality, affiliate partners we've vetted get a small tiebreaker — but affiliate status never moves a poorer match above a better one.
