Looking for a MxToolbox alternative? Here's an honest, side-by-side comparison to help you choose the right domain security tool for your needs.
MxToolbox is a solid, established tool with broad network diagnostic capabilities. However, if you primarily need email authentication and domain security checks, Domain Security Scanner offers a more streamlined experience with all checks unified in a single scan and a free tier with no sign-up required.
MxToolbox is one of the most established names in DNS and email diagnostics, offering a comprehensive suite of individual lookup tools including MX records, blacklist checks, SPF, DMARC, and more. It has been a staple in IT professionals' toolkits for over a decade.

Yes. If you want all your security checks (SPF, DMARC, DKIM, SSL, DNSSEC, security headers) in one scan instead of running separate lookups, Domain Security Scanner is an excellent MxToolbox alternative. Our free tier is also more accessible with no account required.
No. MxToolbox focuses on DNS and email diagnostics but does not analyse HTTP security headers like Content-Security-Policy, HSTS, or X-Frame-Options. Domain Security Scanner includes security header analysis in every scan.
The main reasons to switch are: unified scanning (no more separate lookups), a more modern interface, free tier with no sign-up required (3 scans/day), and inclusion of security header checks. If you need blacklist monitoring, both tools offer this in paid plans.
