FortiManager-VM Base License for Centralized Network Management
Fortinet FMG-VM-BASE is the base license for the stackable FortiManager-VM virtual appliance, providing centralized management for up to 10 Fortinet devices/VDOMs. The license is designed for supported FortiManager-VM virtual appliance platforms and provides a foundation that can be expanded with additional stackable device/VDOM licenses as the network grows. Fortinet identifies the VM-BASE license as supporting 10 licensed network devices and 10 administrative domains in its perpetual FortiManager-VM licensing model.
Description
The FMG-VM-BASE is the base licensing component for Fortinet FortiManager-VM, a virtualized centralized management platform designed to simplify the administration of Fortinet security devices across distributed networks.
Instead of individually configuring and monitoring each Fortinet appliance, FortiManager provides a centralized management environment for managing configurations, policies, devices, administrative domains, and network-security operations.
The FMG-VM-BASE license establishes the initial management capacity for up to 10 Fortinet devices/Virtual Domains (VDOMs). Fortinet’s documentation confirms that FortiManager-VM uses a stackable licensing model, allowing organizations to purchase additional capacity as their infrastructure expands.

Centralized Fortinet Device Management
FortiManager-VM provides a centralized management platform for Fortinet network-security devices.
With the FMG-VM-BASE license, organizations can manage up to 10 licensed devices/VDOMs from a centralized management environment.
This can help network administrators:
- Configure multiple Fortinet devices
- Deploy consistent security policies
- Manage device configurations
- Monitor managed infrastructure
- Organize devices into administrative domains
- Standardize network-security operations
- Reduce repetitive device-by-device administration
Fortinet’s current FortiManager information identifies 10 devices/VDOMs as the default capacity for the FortiManager VM platform.
Virtual Domain (VDOM) Licensing
FortiManager licensing counts devices and VDOMs as managed network-device units.
For FortiManager VM, Fortinet explains that:
- A FortiGate without VDOMs counts as 1 license
- A FortiGate with VDOMs counts according to its licensed VDOMs
- Each VDOM can therefore consume a management license
- Secondary FortiGate units in HA do not incur an additional license count under the applicable rules
This makes the FMG-VM-BASE license suitable for organizations managing either standalone Fortinet appliances or environments that make extensive use of VDOM-based segmentation.
Stackable Licensing
One of the major advantages of FMG-VM-BASE is its expandable licensing architecture.
Fortinet’s perpetual FortiManager-VM licensing model allows additional capacity to be added through stackable upgrade licenses.
For example:
| License | Additional Capacity |
|---|---|
| FMG-VM-BASE | Base capacity – 10 devices/VDOMs |
| FMG-VM-10-UG | +10 devices/VDOMs |
| FMG-VM-100-UG | +100 devices/VDOMs |
| FMG-VM-1000-UG | +1,000 devices/VDOMs |
| FMG-VM-5000-UG | +5,000 devices/VDOMs |
Fortinet specifically documents the VM-BASE plus stackable upgrade model, allowing organizations to scale their FortiManager deployment as the number of managed devices increases.
Scalable Network Management
The stackable design allows businesses to start with a smaller management deployment and expand without replacing the underlying virtual FortiManager appliance.
For example, an organization could begin with:
FMG-VM-BASE → 10 devices/VDOMs
and later add:
FMG-VM-10-UG → additional 10 devices/VDOMs
Additional upgrade licenses can be added as the environment grows.
This is particularly useful for organizations implementing Fortinet infrastructure in phases.
Administrative Domains (ADOMs)
FortiManager uses Administrative Domains (ADOMs) to separate managed devices according to organizational, geographical, or operational requirements.
ADOMs can be useful for:
- Different business departments
- Different subsidiaries
- Multiple customers
- Different geographic locations
- Separate network-security environments
- Multi-tenant management
Fortinet documentation identifies 10 ADOMs / devices for the FMG-VM-BASE perpetual license model.
Note: Fortinet’s licensing behavior and ADOM entitlements can differ between perpetual and subscription FortiManager-VM licensing models. The license entitlement associated with the specific SKU should therefore be used as the final procurement reference.
Centralized Configuration Management
FortiManager helps administrators centrally manage configurations across Fortinet devices.
This can reduce the need to log into each individual firewall and manually repeat configuration tasks.
Centralized management can help with:
- Configuration consistency
- Device provisioning
- Policy deployment
- Configuration revisions
- Standardized templates
- Change management
- Network administration
Policy Management
FortiManager provides centralized management capabilities for Fortinet security policies.
Administrators can develop and deploy policies across managed FortiGate devices, helping organizations maintain consistent security controls.
This is particularly valuable in environments where multiple firewalls need to follow standardized corporate security policies.
Centralized Operations
The FortiManager platform is designed to provide a centralized operational view of managed Fortinet infrastructure.
This can simplify administration of:
- FortiGate firewalls
- Multiple VDOMs
- Distributed network environments
- Branch-office security infrastructure
- Enterprise security deployments
The platform is designed to scale from relatively small environments to deployments involving thousands of managed Fortinet devices when additional licenses are added. Fortinet states that FortiManager-VM licenses can be stacked to significantly increase the number of managed devices/VDOMs.
Virtual Appliance Deployment
Unlike a physical FortiManager appliance, FortiManager-VM is deployed as a virtual appliance.
This provides organizations with flexibility to run FortiManager within supported virtualization environments rather than requiring dedicated physical management hardware.
Fortinet describes FortiManager virtual machines as virtual versions of its hardware appliances designed to run across supported virtualization platforms.
The specific hypervisor and supported configuration should be verified against the FortiManager version being deployed.
Flexible Infrastructure Integration
A virtual FortiManager deployment can be integrated into an organization’s existing virtualization infrastructure.
Depending on the supported platform and FortiManager release, virtual deployment can be used within environments based on supported:
- Virtualization platforms
- Private-cloud infrastructure
- Public-cloud environments
Fortinet notes that current hypervisor support should be checked against the release notes for the particular FortiManager version being deployed.
License Type
The FMG-VM-BASE SKU belongs to Fortinet’s FortiManager-VM licensing architecture.
Fortinet documents both perpetual and subscription FortiManager-VM offerings. The perpetual VM licensing model uses stackable base and upgrade licenses, while newer subscription offerings use separate subscription SKUs.
For an online store, it is therefore important to clearly identify this product as a FortiManager-VM Base License rather than representing it as a physical appliance.
