Cloud WAF Overview

access_time Updated Jun 29, 2022

What is Cloud WAF?

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 full security capabilities of other Signal Sciences agent-based deployment options with matching actionable insights, reporting and DevOps tool integrations.

Uniquely compared to other Cloud WAFs that customers may be used to, the Signal Sciences Cloud WAF shares a unified management console with all other deploymention options thus providing actionable information and key metrics quickly in a single centralized interface for your entire organization.

How does it work?

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.

For additional information about how the Cloud WAF solution works, see our Cloud WAF product page and data sheet.

What is required?

The install process for Cloud WAF can be completed in seconds, the only requirements for deployment are:

  1. A simple DNS change
  2. Your application’s TLS/SSL certificate information

After the DNS change propagates, confirm that Cloud WAF is protecting your applications by viewing the request data populated in the console.

Note: Ensure that your DNS registrar has the ability to create aliases/CNames at the apex (or root) of the domain. If your DNS provider does not support this common feature set, we can recommend several DNS providers based on your implementation. Reach out to your rep for more information.
