Hosted Firewall & Network Security (FortiNet VDOMs)

Multi‑tenant, enterprise‑grade firewalling for IaaS and connected sites without hardware overhead.

The Challenge. Closing The Security Gap

As networks expand and workloads move to cloud, security must keep pace. Traditional appliance models can be slow to scale and costly to manage across many sites or tenants.

You need strong segmentation, policy consistency, and 24/7 monitoring—delivered as a managed service.

Our Expertise. Hosted Firewall Services

We provide hosted firewall services using FortiNet Virtual Domains (VDOMs) to deliver dedicated, isolated security contexts per customer or business unit. Policies, logging, and updates are centrally managed by our security team.

This model scales quickly, reduces hardware footprint, and aligns with both private cloud and connectivity services for end‑to‑end protection.

  • Dedicated Security Contexts: per‑tenant VDOMs for clean separation.
  • Scalable Controls: add capacity or features without on‑site hardware swaps.
  • Managed Service: patching, ruleset hygiene, and monitored alerts
  • Integrated Connectivity: consistent policies across sites and cloud.
