What is a Block Page?
A common feature in a DNS security or web security solution is a block page. If a user attempts to access a blocked resource through a web browser, the security solution redirects the user to a hosted block page. Instead of allowing the web browser to display a "connection failed" message, a block page provides the user information that the resource is blocked.
Custom Block Pages
Securd supports the creation of multiple custom block pages. There are four types of block pages in Securd Protection.
- The default block page from Securd.
- A custom message in the default Securd block page.
- A fully customized HTML block page.
- Redirect to a URL.
You can create as many block pages as you require to support the policies you have in your account.
Branding Block Pages
Changing the Header Logo
Securd is built with a multi-tenant model. Each tenant in Securd is called a Company. In the company's setting, administrators can upload a logo that will be used in the header of the block page. If you select Yes on the Show Company Logo drop down, the custom logo will be shown instead of the Securd logo.
Creating Custom Block Page HTML
Securd supports a simple HTML editor for administrators to create a custom HTML message. With custom HTML as an option, you can create a block page that aligns more with your branding needs and security awareness training requirements.
Applying a Block Page to a Policy
Once you create a custom block page, you can apply the block page to a specific policy. Simply browse to policy you want triggering a custom block page response, and select the custom block page option.
Once you apply the block page to the policy, the network, end-points or browsers subject to that policy will immediately receive the custom response.
Block Pages over Secure Connections
If you are only using the Securd Protection client, this step is not required.
Advanced security features including HTTPS traffic inspection and redirection require users to install and trust the Securd root certificate on their machine or device. If you are protecting devices behind an IP address without the Securd client, installing the Securd root certificate will prevent a broken HTTPS message at the browser and enable the custom block page to be served over HTTPS.
