How secure are Iran's domains?
Most businesses in Iran use a .ir domain. Across 500,771 of them, here's how their security stacks up — aggregate patterns only, never an individual business. As of 2026-07-29.
In the .ir zone — covering Iran — 67.2% of 500,771 graded domains earn an F, well below the 73.8% internet-wide average. DMARC enforcement here stands at 5.1% — below the 11.8% census-wide rate.
We use .ir as a stand-in for Iran, based on the domain's ending rather than where a company is legally registered — so Iran businesses using a generic ending like .com aren't counted here.
