Cloud WAF overview
Last updated 2022-08-24
Cloud WAF is a hosted solution designed for customers that may not have full autonomy over their infrastructure and therefore do not wish to install a Signal Sciences agent and module into their respective environments.
For environments such as these, Cloud WAF is an easily deployable option that provides the same security capabilities of other Signal Sciences agent-based deployment options.
Cloud WAF shares a unified management console with all other deployment options thus providing actionable information and key metrics quickly in a single centralized interface for your entire organization.
Cloud WAF uses the same technology as our other agent-based deployment options under the hood, which means that as a customer, you have full flexibility to deploy wherever your application operates.
To deploy a Cloud WAF instance:
Secure communication between Cloud WAF and the client. Upload a TLS certificate for the domain you are protecting with Cloud WAF to ensure communication between the Cloud WAF instance and the client is encrypted and secure. If your requests will be coming from Fastly’s Edge, you can use a Fastly-managed TLS certificate instead and uploading a TLS certificate is optional.
Create the Cloud WAF instance. Create a new Cloud WAF instance in a geographic location close to the location of your origin. Only Owner users can create and edit Cloud WAF instances. All other user roles will have visibility into your Cloud WAF instances but will not be able to create or edit Cloud WAF instances.
Point DNS to your Cloud WAF instance. After the DNS change propagates, confirm that Cloud WAF is protecting your applications by viewing the request data populated in the console.
Ensure that your DNS registrar has the ability to create aliases or CNAME records at the apex (or root) of the domain. If your DNS provider does not support this, we can recommend several DNS providers based on your implementation. Reach out to our support team for more information.
