DNS Security Tools
Verisign, one of the most trusted names in internet security, develops and tests tools that improve the security, stability, and resiliency of the internet.
DNSSEC Debugger
The DNSSEC Debugger, a tool for inspecting the "chain of trust" for a specific DNSSEC-enabled domain name, provides a step-by-step DNSSEC validation of the name and highlights any problems found.
DNSSEC Scoreboard
The DNSSEC Scoreboard shows the number of domains secured by DNSSEC in the .com and .net zones.
Transitive Trust Checker
The Transitive Trust Checker produces DNSSEC-based trust-relationship graphs for one or more given DNS zones, showing how the zones are related based on names, network addresses, and autonomous system numbers.
