Smart outsourcing

Some IT creates added value, while other types are supportive. Use that as a starting point for outsourcing.

Cost Efficiency

Complete IT packages may seem like the safe option, but when you consider the costs, other choices often make more sense.

IT flexibility & control

Outsourcing doesn’t mean losing control; it actually provides more flexibility and control.

Cloud repatriation

The cloud is not a final destination: You should continuously evaluate and adjust your cloud environment as needs evolve.

Continuous Security Validation

Applies to Any service with an external networkAudience All customersLast reviewed September 2026

Quick answer

Portal runs automated, ongoing security scans on every internet-exposed IP you own, surfacing CVEs, misconfigurations and leaked services before an attacker finds them. The feature is powered by Hadrian, and lives under Security in the sidebar in Portal.

Continuous Security Validation is separate from the OS-level firewall and hardening steps you configure yourself, it's an external, ongoing scan of what your public IPs actually expose to the internet.

What it does

  • Scans every public IPv4 you own, from Flexible VPS, firewalls, VPN, Bare Metal, and reserved holds.
  • Surfaces exposed services, misconfigurations, and known software vulnerabilities as they're found, not only after an incident.
  • Grades each registered IP: Critical, High, Medium, Low, Info, or No risks found.
  • Lets you generate a tenant-wide Security Report (by month) and download it as a PDF.
  • Matches Security Bulletins to your registered addresses.

Getting started

1

Deploy something with a public IP

Results appear automatically once you have a VPS, Bare Metal server, or other service with an external network. There's nothing to configure beforehand.

2

Register an IP for validation

Open Security in the sidebar and use Add to Validation to start (or resume) validating an address. Remove takes it back out of validation. This is separate from the Monitoring page, which is where you configure your own availability checks.

3

Review findings

Use View Results on a registered IP to see its grade and risks. Use Refresh to re-check an address.
