Where Sucuri SiteCheck wins

Sucuri has been in the WordPress security trenches longer than almost anyone. Their plugin sits inside hundreds of thousands of WP installs, which means they see new malware variants the day they ship. SiteCheck is the free public-facing scanner that benefits from that telemetry. If you paste a WordPress site URL into SiteCheck and it's been compromised with a known malware family — backdoor uploads, SEO spam injections, credit-card skimmers, cryptominers — Sucuri will usually catch it. PhishGuard won't, because that's not our problem space and we don't have the signature database.

Sucuri also does what scanners can't: they'll clean your site for you. The Pro plan (around $199/year) is a managed service — they remove the malware, harden the install, and run a Web Application Firewall in front of it. Now that they're part of GoDaddy, that offering only got more entrenched. If your WordPress site is on fire, SiteCheck (and Sucuri the company) is the right tool.

Where PhishGuard wins

SiteCheck is optimized for "is my website infected?" PhishGuard is optimized for "is this link in an email about to steal my credentials?" Different verbs. SiteCheck checks if your own sites are malware-free. PhishGuard checks if someone else's URL is a phishing trap before you click it. For that job — investigating an unknown link, especially a brand-new one — PhishGuard's 13+ sources plus Claude AI page analysis catch phishing kits that aren't on any blocklist yet. SiteCheck's blacklist check returns "clean" on those URLs because nobody has reported them.

PhishGuard also ships the rest of the IR toolkit: an email message scanner (paste an .eml, get verdicts on every link plus a header analysis), a URL deobfuscator that unwraps Outlook Safe Links and Proofpoint URLs, a typosquat generator that checks live DNS for lookalike domains, and a flat-rate self-serve API at $9/mo. SiteCheck has none of those — its API requires a paid Sucuri plan, and there's no email tooling at all. For Slack alerts on new phishing verdicts, webhook delivery into Splunk, or a public Atom feed for SIEM ingest, PhishGuard ships those today.

Who each is for

Pick Sucuri SiteCheck if you run WordPress

You own a WP site (or fifty) and you want to know if any of them are infected. You want a vendor that'll also clean the mess up and stick a WAF in front of it. Sucuri is the category leader for a reason — use them.

Pick PhishGuard if you're investigating links, not your own sites

You got a suspicious link in an email. A user reported a phishy URL. You need to scan fifty URLs from a CSV. You want an API in your incident-response pipeline. You want Slack alerts when new phishing campaigns hit your brand. That's PhishGuard.

Use both — they don't overlap much

Sucuri for your own WordPress sites. PhishGuard for everything else. Honestly, most security teams that use one end up using the other.
