Server Security Without the Sysadmin: What Managed VPS Covers

Server security has a well-deserved reputation for being both critically important and deeply tedious. The fundamentals — keeping packages updated, restricting SSH access, configuring firewalls, rotating credentials — are not complex individually. But they require consistent attention that most product teams do not have the bandwidth to give.

On a self-managed server, security is entirely your responsibility. A single misconfigured firewall rule, an SSH port left open to the world, or an unpatched vulnerability in an installed package can lead to a compromise. Security incidents are expensive not just technically but in terms of customer trust and regulatory consequences.

At Northstar VPS, security hardening is applied to every server before you ever see it. Firewall rules allow only the ports your application needs. SSH is locked down with key-based authentication only. Unused services are disabled. Default credentials are replaced.

OS-level security patches are applied automatically on a regular cadence. When a critical CVE is published, we assess impact and apply patches to affected servers, prioritising severity. You do not need to track the Linux security mailing list or schedule your own patch windows.

DDoS protection sits upstream of your server. Volumetric attacks — the kind that try to overwhelm your server with traffic — are absorbed at the network edge before they reach your application. This protects your uptime against a common category of attacks without any configuration on your part.

Automated backups mean that even in a worst-case scenario, recovery is possible. Daily backups are taken and stored securely off-server. If a security incident requires a clean restoration, you have a verified recent backup to restore from.

What managed security does not cover is application-level security. Vulnerabilities in your own code — SQL injection, insecure API endpoints, improper authentication — are your responsibility to find and fix. Infrastructure security and application security are complementary, not interchangeable. We handle the server layer; you handle the application layer.
