Atomicorp Atomic ModSecurity Rules & WAF vs Dorothy: Side-by-Side Comparison (2026)

Startups and SMBs already running Apache or Nginx need Atomicorp Atomic ModSecurity Rules & WAF because it delivers OWASP Top 10 coverage without forcing a platform swap or managed WAF licensing costs. The ruleset gets monthly updates for emerging CVEs and integrates directly into existing ModSecurity deployments, meaning faster deployment than rip-and-replace alternatives. Skip this if your stack is IIS-heavy or you need API-specific protections beyond the core SQL injection and XSS defenses; the rule coverage prioritizes web application attacks over API attack surfaces.
