If your business is using web applications, this means that they may be likely connected to the Internet 24/7. In order to prevent you from being hacked, and to reduce data theft and downtime, it’s important to use a cloud-based firewall to protect your website and app. Using a cloud-based firewall will ensure that it will continue running if the on-site server goes down. Attacks are becoming more sophisticated and frequent, so it’s important to have a service you can rely on at all times. Your service should be able to detect attacks automatically before they can penetrate the system. It helps if there is a dashboard or a way to see behavior analysis so that users can see the traffic and the number of attacks and create rulesets to prevent them from being successful. Read on to learn about the top cloud firewalls that can help your business.
