Frequently asked questions
What share of .app domains are effectively unprotected?
88.6% of the 2,425,305 graded .app domains score an F, meaning core protections like enforced DMARC are missing and the domain can typically be email-spoofed. As of 2026-07-29.
Does this cover every Software business?
No. It covers the businesses that chose the .app ending. Most Software firms sit on a generic ending like .com and are not captured here — treat this as a sector-flavoured sample, not a census of the whole industry.
