.hk LOCK

.hk LOCK is an automated registry lock service that protects your .hk /.香港 domain names from unauthorised seizure by cyber criminals, a malicious online activity commonly known as “domain hijacking”. By hijacking your domain names, the criminals can divert Internet traffic meant for your websites to other destinations, doing substantial and irreversible harm to your business and reputation.

What is at stake?


A number of internationally renowned domain names have been victims of domain hijacking recently. The damages to you could include:

  • Website defacement: your customers and visitors could lose confidence in your organisation; damage to your reputation could also be widely publicised.
  • Loss of revenue / disruption to operations: if your website is your major sales channel or service portal, revenue loss and service disruption are inevitable during the hijacking.
  • Leakage of confidential information: email traffic could be diverted and stolen by cyber criminals; confidential correspondences would be compromised.

Benefits of using .hk LOCK:


  • An extra, separate, layer of protection of your .hk /.香港domain names beyond your registrar / ISP; similar to the 2-factor authentication process commonly employed by Internet banking.
  • Lowering of security risks – even if all of your domain name credentials are accidentally compromised, .hk LOCK will be the final gatekeeper of your .hk / . 香港domain names against unauthorised modifications.
  • Peace of mind for your online brand security – using .hk LOCK is like having two locks on the main door. Most households nowadays have more than one lock on the main door for adequate protection.
  • Supports 24 x 7 lock and unlock service – .hk LOCK processes “lock” and “unlock” domain requests any time of the day, any day of the year online.

.hk LOCK will “lock” your domain names against any changes of name server information and domain host information. The prohibition is at the “registry side”, that is, at HKIRC’s system. Your registrar of .hk / .香港domain names will appoint authorised persons, who can request an “unlocking” of the modification functions online via .hk LOCK system and panel. HKIRC will only unlock the domain name for a short interval after a verification process with the authorised person(s) has been completed. These measures, and the underlining security policy framework, will ensure your .hk / .香港 domain names are protected with the highest security standard of the industry.

Who should use .hk LOCK?


  • Banks and financial institutions, governmental departments, utilities and public services;
  • Owners of brand and trademark domain names;
  • Online shops, online service providers;
  • Anybody who communicates and transacts confidentially with their clients online regularly via their own domain names;
  • Any domain names receiving high traffic volumes;
  • Any websites handling sensitive and confidential information.
