All generic extensions and some country-code ones support a security lock option whose function is to block unwanted transfers of existing domains. Many registry organizations that supervise ccTLDs that do not support this feature are in the process of introducing it for the sake of security and for the convenience of the domain name registrants. A domain name can be transferred only if it is unlocked and only a registrant who has been granted access to the account with the current domain name registrar can do that. New domains are registered with the lock option enabled intentionally, so as to prevent any unsolicited transfer attempts. The lock option is one of the safety measures for controlling the transfer of active domain names between registrar companies that have been introduced over the years.
