Sucuri’s powerful cloud-based Web Application Firewall (WAF) is your first line of defense against modern cyber threats. Designed to safeguard websites from hack attempts, DDoS attacks, zero-day vulnerabilities, and malicious traffic, our WAF acts as a virtual shield—hardening your web server and proactively patching known and emerging vulnerabilities.

What sets Sucuri apart is our commitment to continuous threat research and custom rule configuration. Our security experts monitor evolving attack vectors and deploy real-time updates to block even the most sophisticated threats. Whether you’re running WordPress, Joomla, Magento, or any other CMS, our WAF is tailored to meet your platform’s unique security needs.

Frequently Asked Questions

Does this plan include malware cleanup?

The Website Firewall is a standalone product. If you believe you are infected, you can subscribe to a Platform Plan which includes the Website Firewall as well, or request a One-Time Cleanup

Is this a subscription service?

Yes, all plans are subscriptions. If you wish to stop the subscription you will need to submit a general request form via your dashboard.

Can I cover my subdomains and test sites?

A license is required for every subdomain (this.site.com) and unique website structure?

Will the Website Firewall affect my SEO?

No, the Firewall does not affect your SEO, except in a positive way through improved performance when taking advantage of our caching options. Google and other search engine crawlers still associate your content with your domain regardless of the DNS change. Local businesses should be sure to select the closest server to their geographical area when setting up the Firewall.

Will you configure the Website Firewall for me?

Yes, if you require assistance we’ll be happy to help you get configured. We only need access to your DNS manager, but be sure to submit the request via the ticketing system.
