Which companies don't have DNSSEC enabled?
DNSSEC (Domain Name System Security Extensions) adds cryptographic signatures to DNS records, preventing attackers from redirecting users to malicious sites through DNS cache poisoning or spoofing. Without DNSSEC, DNS responses can be tampered with in transit. The domains below were found by LynxRadar to have no DNSSEC validation enabled.
LynxRadar scanned 2378 domains including Fortune 500 companies and Y Combinator startups. Of those, 2063 (87%) 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.
