A VPS provides isolation from other virtual machines, but security still depends on how the server and application are managed.
- Keep the operating system, control panel, and applications patched.
- Use SSH keys or strong unique passwords and enable MFA where available.
- Restrict administrative ports and remove unused services.
- Configure a firewall, malware monitoring, and tested backups.
- Give each user only the access they need and review logs regularly.
Security is shared between the provider, the server administrator, the application owner, and any third-party software vendor.
