Pure technical comparison — feature coverage, architecture, and operational impact.
DirectAdmin is lightweight and established. HPanel focuses on modern security visibility, built-in isolation, and integrated performance features that usually require add-ons or custom hardening.
| Area | HPanel | DirectAdmin |
|---|---|---|
| Resource Isolation | Built-in cgroups limits per account | Typically handled via OS-level policies; CloudLinux optional |
| Malware / Antivirus | Realtime scan + scheduled scans + quarantine | Often external tooling / add-ons |
| Security Visibility | Live dashboard: Fail2Ban/WAF/malware events | Logs available; dashboards depend on integrations |
| WAF | ModSecurity + OWASP rules built-in | Possible with manual configuration |
| Performance Stack | Nginx + FastCGI cache + Redis + per-account pools | Configurable; caching depends on setup |
| Admin / Reseller / User | Separated panels (WHM/cPanel-like model) | Reseller support available; UI model differs |
What matters for hosting providers managing many accounts.
