As answered by people managing Prime Dev Force Security and HTTP Observatory.
Prime Dev Force Security's answer
The free check needs no account and takes seconds. Every finding explains why it was flagged and how to fix it, and the scoring method is published. When you want more, Pro adds daily monitoring with Slack, Discord or webhook alerts for $12/month, and Agency adds branded client reports for 30 domains at $49/month. It is honest about its scope: an outside-in configuration check, not a penetration test.
Prime Dev Force Security's answer
It checks web and email security in one report. Most free tools cover headers, or TLS, or DMARC; Prime Dev Force checks HTTPS, TLS, security headers, DNS and SPF/DKIM/DMARC together, and shows the evidence, severity and confidence behind every finding. The result is a ranked fix list, not just a grade.
Prime Dev Force Security's answer
Small business owners, developers and freelancers who run their own websites, and agencies who look after many client sites and need to show clients what was fixed.
