Secure Site Seal - Overview & Installation

Apr 9, 2024


A site seal that proves that you have received GMO GlobalSign's authentication service and can only be used by websites that have introduced SSL certificates. It is an effective item that strongly appeals to users of your security efforts and shows that your site can be trusted. It is used by more than 10,000 websites.

If you add a statement to the effect that your site is protected by SSL next to the site seal, you can appeal to users that you are taking security measures. Here are some simple example sentences, so please refer to them.

e.g. This site is certified by GMO GlobalSign. The transmission of information from SSL-enabled pages          are protected by encryption.
e.g. Your personal information on this site is protected by GMO GlobalSign's SSL.
Example: This site uses an SSL digital certificate issued by GMO GlobalSign.

View your site's profile with the site seal

The display of the site seal makes it clear at a glance that the site has been certified by GMO GlobalSign, a third-party certification authority, so users can use the site with peace of mind. You can check the profile details of the site by clicking on the site sticker.

* When updating, the expiration date of the site seal may not be updated because the old information is cached. The new information will be displayed when the cache information is automatically updated.

How to install a site seal

After selecting the desired design and size, the script will be displayed in the "Step 3: Script Installation" section.

Step 1: Choose a seal design​

* Please use the white design when the background of the area where the sticker is placed is dark.

Step 2: Select the size of the seal

Step 3: Install the script

Copy and paste the following script into the HTML source of your site.


This completes the configuration. After that, GMO GlobalSign's site seal server will authenticate your website and dynamically distribute the site seal.

* In order to automatically identify the certificate installed on the server, all seal scripts are the same regardless of the service.
*Please note that if you are using a script before January 17, 2024, the site seal will not be displayed after December 20, 2024, except for the Congressional, Mayor, and Political Party Verification Service.

About the copy protection of the site seal

Prevent image copying

JavaScript suppresses right-click and prevents image copying.

* The gif-type seal is easy to copy, but the GMO Global Sign site seal cannot be copied.

Hidden on unauthenticated sites

It is dynamically generated by JavaScript, so it cannot be displayed on unauthenticated sites. Even if you post a copied image, in the case of unauthorized use, the profile will not be displayed by left-clicking.

* If the site viewer does not allow the use of JavaScript, a blank site seal will be displayed instead of a proper site seal. Please see the example on the right.
