Frequently asked questions
What share of .io domains are effectively unprotected?
71.6% of the 958,000 graded .io 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 Technology business?
No. It covers the businesses that chose the .io ending. Most Technology 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.
