Which companies are missing SPF records?
SPF (Sender Policy Framework) is a DNS record that specifies which mail servers are authorized to send email on behalf of a domain. Without SPF, anyone can send email that appears to come from the domain — a common technique in phishing and spam campaigns. The domains listed below were found by LynxRadar to have no SPF record published in their DNS.
LynxRadar scanned 2599 domains including Fortune 500 companies and Y Combinator startups. Of those, 751 (29%) were found to have this security gap. The data above is updated continuously as new domains are scanned. Scan any domain to check its status.
