Can I use Deflect while my website is under construction?

Yes. In fact, we recommend it.

The earlier you protect your website behind Deflect, the fewer people will know its IP address, and this will reduce the chances of an attack reaching your server.

Register your website as early as possible on Deflect. You will still be fully able to access any web administration panel through Deflect, or connect directly to the IP address of your server should the need arise.
