Comparison
ZeriFlow vs Sucuri SiteCheck
Sucuri SiteCheck is a post-incident tool — it excels at detecting malware that has already infected your site and checking whether you are on security blacklists. ZeriFlow is a proactive configuration auditor: it surfaces misconfigurations in TLS, HTTP headers, cookies, DNS, and email authentication before attackers find them. The two tools answer different questions.
