Sucuri SiteCheck is one of the best-known free website scanners. It visits a site the way an ordinary visitor would and inspects the public pages for malware injections, SEO spam, defacement, and out-of-date CMS software, and it checks the domain’s status against major blacklists. It is remote-only, so it sees what is visible in the browser, not what is on the server — Sucuri’s paid platform adds a server-side scanner, a website firewall, and hands-on incident cleanup. For knowing quickly whether a site is showing warning signs to visitors or search engines, SiteCheck is a fast, trusted first look.
Lavawall® Scout is also a remote scanner, but its job is the whole external attack surface rather than malware specifically. In one scan it checks email authentication (SPF, DKIM, DMARC), TLS and certificates, DNS hygiene (DNSSEC, CAA), security headers and WAF, open ports and exposed admin panels, WordPress plugins/themes with known CVEs, exposed files and backups, and blacklist reputation — and it fingerprints page content to flag defacement, newly-injected external scripts, and new outbound links. It is multi-tenant: a module of the Lavawall® platform built for MSPs managing many client domains.
The honest answer: if your immediate question is “is this site infected or blacklisted, and can someone clean it up,” Sucuri is purpose-built for that and its paid platform closes the loop with cleanup and a firewall. If your question is “what is this domain’s overall security posture — can it be spoofed, is the certificate or DNS weak, are services or files exposed, are plugins vulnerable, is it flagged,” Scout answers all of that in one pass.
Where Lavawall® Scout wins
Whole attack surface in one scan. SiteCheck answers “is this site infected or blacklisted.” Scout answers that and reports email spoofability, TLS and certificate health, DNSSEC/CAA, security headers, open ports, exposed admin panels, and WordPress plugin CVEs — the exposures that cause incidents in the first place, not just the symptoms after one happens.
Email authentication. Scout reports SPF, DKIM, and DMARC with enforcement mode in plain English, detects the mail provider, and lists exposed email addresses harvested from public pages. SiteCheck does not assess email authentication.
Known-CVE matching and exposed-file discovery. Scout detects WordPress and library versions and matches them against an NVD-backed CVE database, and (only on WordPress sites) checks for exposed .env, /.git/, wp-config.php backups, and directory listing — stopping the moment a WAF block is detected.
Multi-tenant for MSPs, with white-label. Scout is part of the Lavawall® platform: one console across every client domain, scheduled scans, trend history, native email reports with charts, and the ability to embed Scout on your own marketing site.
One platform. The same console also handles 7,500+ application patching, M365 / Entra / Azure breach detection, GRC compliance, helpdesk, and remote support — native CAD billing.
Where Sucuri SiteCheck wins
Malware-signature and SEO-spam detection. Sucuri’s core strength is recognising injected malicious code, spam keywords, malicious redirects, and defaced pages from the page source, backed by years of website incident-response data. For malware-signature detection specifically, Sucuri is stronger than Scout’s defacement/injected-script heuristics.
Blacklist reputation breadth. SiteCheck checks several major blacklists (Google Safe Browsing, McAfee, Norton, PhishTank and others). Scout uses commercial-safe feeds (PhishDestroy, URLhaus) for reputation; Sucuri’s blacklist breadth is a long-standing strength.
Cleanup and a website firewall. The paid Sucuri Platform adds a server-side scanner, a cloud website firewall (WAF), and hands-on malware removal — an incident-response service. Scout reports posture; it is not a cleanup service.

Who should pick which?
Pick Lavawall® Scout if…
You want to understand a domain’s whole external posture — email spoofability, TLS, DNS, headers, ports, CVEs, reputation, and defacement — in one scan rather than a malware-only verdict.
You are an MSP managing many domains and want a multi-tenant console, scheduled scans, trend history, email reports, and a white-label scanner for your own site.
You want the scanner bundled with patching, breach detection, GRC, and helpdesk at MSP pricing.
Pick Sucuri if…
Your immediate question is “is this site infected or blacklisted” and you want best-in-class malware-signature and SEO-spam detection plus broad blacklist coverage.
You need server-side scanning, a cloud website firewall, and hands-on malware cleanup — the paid Sucuri Platform’s incident-response service.
Frequently asked
- Is Sucuri SiteCheck the same as Lavawall® Scout?
- They overlap but emphasise different things. SiteCheck is a free remote scanner focused on malware injections, blacklist status, SEO spam, and defacement. Scout is a full external attack-surface scanner: email authentication, TLS, DNS, headers, ports, WAF, WordPress plugins and CVEs, exposed files, and reputation, plus defacement and injected-script detection. Both are remote and need no server access.
- Does Sucuri detect malware better than Scout?
- For malware-signature and SEO-spam detection and for malware cleanup, Sucuri is stronger — it is built for that, with years of incident data and a paid cleanup service. Scout detects defacement, injected external scripts, and reputation/blacklist status, but is not a malware-removal service. For whole-surface posture across email, DNS, TLS, ports, and CVEs, Scout is broader.
- Can either scanner see server-side files?
- Neither free remote scanner sees server-side files; both look only at what is public. Sucuri’s paid platform adds a server-side scanner. Scout is external by design; for server-side coverage the broader Lavawall® platform uses an endpoint agent on the systems you manage.
- Is Scout multi-tenant for MSPs?
- Yes — one console across every client domain, scheduled scans, trend history, email reports with charts, and white-label embedding on your own marketing site.
