Sucuri SiteCheck review
A free URL checker for visible website threats, not server-side files or uploaded files.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Sucuri SiteCheck is a browser-based scanner for website owners and webmasters who want to check a URL for visible security issues. Its free scan looks for malware and viruses, blacklist status, defacements, outdated CMS software and plugins, and other anomalies in externally served source code. It is aimed at remote website checks, including WordPress sites, rather than scanning files on a computer or files uploaded for analysis.
The scope is the key consideration. SiteCheck can flag suspicious links, redirects, iframes, JavaScript, spam, and configuration issues that appear in a site’s served content. It also checks for outdated extensions and WordPress-specific issues. Because the scanner works remotely, it cannot inspect server-side files; Sucuri says server-side scanning requires the Sucuri Platform. This makes SiteCheck useful as an initial URL check, but not a substitute for examining a site’s underlying server environment.
SiteCheck is free, with a single Free plan, and is available on the web. Sucuri provides chat and documentation as support channels. The vendor states that results are not guaranteed, so site owners should treat a scan as a signal rather than assurance that a website is clean. Choose it for a no-cost check of externally visible website issues; choose another approach if you need uploaded-file scanning or visibility into server-side files.
