Whether you’re an agency managing dozens of client sites, a developer maintaining custom builds, or a small business owner running a legacy CMS, keeping your website secure without breaking functionality can be a challenge. Updates aren’t always feasible: plugins may conflict, themes may be outdated, or the CMS may no longer be supported. That’s where virtual patching comes in.
Sucuri’s Web Application Firewall (WAF) provides a proactive layer of protection that blocks known vulnerabilities before they’re exploited and without requiring changes to the site’s code. It’s a scalable solution for teams who need to maintain uptime, avoid emergency fixes, and deliver secure experiences across diverse environments. With virtual patching, you can confidently protect your site while planning updates on your own timeline.
Virtual patching is a security technique that acts as a protective layer between your website and incoming traffic, intercepting exploit attempts before they reach vulnerable code. For developers and agencies managing legacy systems, heavily customized themes, or unsupported plugins, virtual patching offers a way to mitigate risk without modifying source code. Sucuri’s Web Application Firewall (WAF) uses heuristic and signature-based detection to block known threats in real time, allowing teams to maintain uptime and functionality while planning safe updates.
Secure Your Site Today
We employ some of the best minds in website security to monitor the threat landscape. When our threat researchers discover something that can harm a site, they create a signature for it, and then add the signature to our WAF. These frequent, ongoing updates keep our WAF recognizing threats and protecting websites from malicious traffic like bots and malware.
