FAQs
Registry locks are the most effective preventive measure to reduce the risks of DNS hijacking and abuse. Adding a registry lock to a domain prevents domain name changes at the registry level without a manual verification process, significantly minimizing the risk of DNS hijacking.
Registrar locks, also known as clientTransferProhibited, are security settings applied at the domain registrar level that prevent unauthorized domain transfers between registrars by requiring explicit permission from the registrar.
WHOIS locks are security features that prevent unauthorized changes to a domain’s WHOIS information. Unless unlocked by a registrar, a WHOIS lock restricts edits to a domain’s contact information, such as the registrant details, administrative contacts, and technical contacts.
Constantly evolving domain portfolios: If your domain portfolio is changing with the launch of new brands, the retirement of old ones, developing operations in new markets, as well as buying and selling businesses, it’s essential to ensure they have the right security in place.
Updates at domain registries: Domain registries are constantly updating their offering and processes, and as new domain extensions become available for locks, it's important to ensure you're taking advantage of them.
