Ubuntu is one of the most widely used Linux distributions for both individual users and enterprise environments. While standard Ubuntu LTS releases already provide long-term maintenance and security updates, organizations running critical workloads often need longer support periods, broader security coverage, compliance tools, and professional technical assistance.
Ubuntu Pro, provided by Canonical, is a comprehensive subscription service designed specifically to address these enterprise requirements.
Ubuntu Pro does more than extend the support lifecycle of Ubuntu. It also provides expanded security maintenance, Kernel Livepatch, security hardening and compliance capabilities, centralized management, and optional professional support directly from Canonical.
What Is Ubuntu Pro?
Ubuntu Pro is an enterprise-focused subscription that provides extended security, maintenance, and support services for Ubuntu LTS systems.
With standard Ubuntu LTS releases, security maintenance is mainly focused on packages available through the Main repository. Ubuntu Pro expands this coverage significantly.
With Ubuntu Pro, organizations can receive security maintenance for packages from both the Main and Universe repositories for up to 10 years.
When the Ubuntu Pro Legacy add-on is included, security and maintenance coverage can be extended by another five years, providing a total lifecycle of up to 15 years.
This makes Ubuntu Pro especially useful for systems that are expected to remain operational for many years, including:
- Physical servers
- Virtual machines
- Application servers
- Database servers
- Production environments
- Government systems
- Industrial systems
- Private cloud infrastructures
Expanded Security Maintenance
One of the most important features of Ubuntu Pro is Expanded Security Maintenance, or ESM.
ESM extends security update coverage beyond the standard Ubuntu operating system packages.
Ubuntu Pro Full Stack coverage includes security maintenance for more than 36,000 open-source DEB packages, while Infra-only coverage focuses on more than 4,700 packages available through Ubuntu’s Main repository.
This can be particularly important for organizations using open-source technologies such as:
- PHP
- PostgreSQL
- OpenSSL
- Redis
- GCC
- Nagios
- Python libraries
- Development tools
- Application dependencies
A server may have a fully updated operating system while still running vulnerable application libraries or third-party packages.
Ubuntu Pro addresses this problem by extending security maintenance to a much broader portion of the Ubuntu software ecosystem.
Kernel Livepatch Support
Applying security updates to production systems can sometimes require a system reboot.
For environments operating 24/7, frequent reboots may create operational challenges, service interruptions, or additional maintenance requirements.
Ubuntu Pro includes Canonical Livepatch, which allows certain critical and high-severity Linux kernel security updates to be applied while the operating system continues running.
This can significantly reduce the need for immediate reboots after kernel security updates.
Livepatch can be particularly valuable for:
- Web servers
- Database servers
- Virtualization environments
- Critical production systems
- High-availability platforms
- Business-critical applications
It is important to understand that Livepatch does not completely eliminate the need for server reboots.
However, it can reduce the urgency and frequency of rebooting systems specifically for supported kernel security vulnerabilities.
Security Hardening and Compliance
Ubuntu Pro is not only about security updates.
It also includes tools and capabilities designed to help organizations meet enterprise security and compliance requirements.
Ubuntu Pro provides support and tooling for standards and frameworks such as:
- CIS
- FIPS
- DISA-STIG
Canonical also provides the Ubuntu Security Guide, which can help organizations automate and standardize system-hardening configurations.
These capabilities can be especially valuable in industries such as:
- Government
- Finance
- Defense
- Healthcare
- Data centers
- Regulated enterprise environments
For example, manually configuring hundreds of Linux servers according to a security baseline can require significant administrative effort.
Using predefined security profiles and automated hardening tools can make it easier to establish consistent configurations across the infrastructure.
Centralized Management with Landscape
Managing a small number of Linux servers manually may be straightforward.
However, once an environment grows to dozens or hundreds of Ubuntu systems, configuration management, security monitoring, package updates, and inventory management become significantly more complex.
Ubuntu Pro includes access to Landscape SaaS, Canonical’s centralized management platform for Ubuntu systems.
Landscape can help organizations centrally manage areas such as:
- Package updates
- Security status
- System inventory
- Resource usage
- Compliance status
- System configuration
- Administrative policies
For enterprise environments with a large Ubuntu footprint, centralized management can significantly reduce operational complexity.
Instead of managing every server independently, administrators can monitor and manage multiple Ubuntu systems from a central platform.
Can Existing Ubuntu Systems Be Upgraded to Ubuntu Pro?
Yes.
One of the major advantages of Ubuntu Pro is that organizations do not normally need to reinstall existing Ubuntu LTS systems.
Existing supported Ubuntu LTS installations can be attached to an Ubuntu Pro subscription.
This allows organizations to enable Ubuntu Pro services on existing production systems without redeploying the operating system.
Once the subscription has been attached, administrators can enable the appropriate Ubuntu Pro services based on their security and operational requirements.
This makes adoption much easier for organizations that already have dozens or hundreds of Ubuntu servers in production.
Ubuntu Pro Pricing
Ubuntu Pro pricing varies depending on the type of system, workload, and required support level.
As of August 31, 2026, Canonical’s published Ubuntu Pro Enterprise pricing includes the following options:
| System Type | Ubuntu Pro |
|---|---|
| Workstation | USD 25 per machine/year |
| Server – Unlimited VMs | USD 500 per machine/year |
One particularly important part of the Ubuntu Pro server subscription model is the Unlimited VMs option.
Depending on Canonical’s applicable licensing terms, an Ubuntu Pro subscription assigned to a physical server can cover Ubuntu virtual machines running on that host.
For virtualization environments with many Ubuntu virtual machines, this licensing approach can make Ubuntu Pro particularly attractive.
Organizations should still review Canonical’s current subscription terms before purchasing licenses for large virtualization environments.
Ubuntu Pro with 24/7 Enterprise Support
Some organizations need more than security updates.
They may also require direct technical assistance from Canonical engineers when critical problems occur.
Ubuntu Pro can therefore be combined with professional enterprise support.
Current published pricing includes:
| System | Support Level | Annual Price |
|---|---|---|
| Workstation | 24/7 Full Support | USD 300 |
| Server | 24/7 Infra Support | USD 1,775 |
| Server | 24/7 Full Support | USD 3,400 |
Canonical also provides weekday support options at a lower cost compared with 24/7 support.
The difference between Infra Support and Full Support is important.
Infra Support primarily focuses on the Ubuntu operating system and infrastructure packages available through the Main repository.
Full Support provides broader coverage across the Ubuntu software ecosystem, including supported packages from the Universe repository.
For this reason, organizations should select their support level based not only on price but also on the applications and software components running on their servers.
Is Ubuntu Pro Free for Personal Use?
Yes.
Ubuntu Pro is not exclusively a paid enterprise product.
Canonical provides a free personal Ubuntu Pro subscription for up to five machines.
Eligible active Ubuntu community members may receive coverage for up to 50 machines.
This makes Ubuntu Pro particularly useful for:
- Personal computers
- Home labs
- Development environments
- Test servers
- Learning environments
- Small virtualization labs
Users can therefore benefit from many Ubuntu Pro security capabilities without purchasing a commercial subscription for personal use.
However, the free personal subscription should not be confused with Canonical’s commercial enterprise support offerings.
Ubuntu Pro on AWS, Azure, and Google Cloud
Ubuntu Pro is not limited to physical servers or private data centers.
Ubuntu Pro images are also available through major public cloud platforms, including:
- Amazon Web Services
- Microsoft Azure
- Google Cloud Platform
In public cloud environments, Ubuntu Pro pricing is generally integrated into the virtual machine’s hourly or usage-based billing.
Canonical indicates that Ubuntu Pro pricing in public cloud environments is typically calculated as an additional percentage of the virtual machine’s underlying compute cost.
The exact cost depends on factors such as:
- Cloud provider
- Instance type
- CPU configuration
- Memory
- Region
- Runtime duration
Organizations planning to deploy Ubuntu Pro in AWS, Azure, or Google Cloud should therefore check the current pricing offered by their cloud provider.
Ubuntu Pro Legacy: Up to 15 Years of Security Maintenance
Some enterprise applications cannot easily be migrated to a newer operating system version.
This can happen because of:
- Application compatibility requirements
- Vendor certifications
- Legacy software dependencies
- Industrial equipment requirements
- Regulatory restrictions
- Complex migration projects
Ubuntu Pro offers a Legacy add-on for these scenarios.
The Legacy option extends security maintenance by an additional five years.
Combined with standard Ubuntu Pro coverage, organizations can receive security and maintenance coverage for Ubuntu systems for up to 15 years.
Canonical currently prices the Legacy add-on at an additional percentage of the regular Ubuntu Pro subscription cost.
This can be particularly useful for organizations operating long-lifecycle systems where upgrading the operating system every few years may not be practical.
Who Should Consider Ubuntu Pro?
Ubuntu Pro is not necessarily required for every Ubuntu installation.
For example, a small test environment that can regularly be upgraded to a newer Ubuntu LTS version may not require a commercial subscription.
However, Ubuntu Pro can provide significant benefits in several scenarios.
Critical Production Systems
For systems where downtime has a direct business impact, Kernel Livepatch and extended security maintenance can help improve availability and security.
Government and Regulated Organizations
Organizations that need to comply with security frameworks such as CIS, FIPS, or DISA-STIG can benefit from Ubuntu Pro’s compliance and hardening capabilities.
Large Ubuntu Environments
Companies running dozens or hundreds of Ubuntu systems can use Landscape to improve centralized management, security visibility, and operational consistency.
Long-Lifecycle Applications
Ubuntu Pro’s extended maintenance period can be useful when applications must remain on the same Ubuntu release for many years.
24/7 Infrastructure
Organizations operating continuously available services can benefit from Livepatch by reducing the need for immediate server reboots after supported kernel security updates.
Is Ubuntu Pro Worth It?
The answer depends on the environment.
For personal systems, development environments, and home labs, the free Ubuntu Pro subscription can provide additional security benefits at no cost.
For enterprise systems, the decision should not be based solely on subscription pricing.
Organizations should also consider the potential cost of:
- Unpatched vulnerabilities
- Legacy software
- Operational downtime
- Security incidents
- Compliance failures
- Emergency maintenance
- Unsupported operating systems
A security vulnerability affecting a critical production server can potentially cost significantly more than an annual Ubuntu Pro subscription.
For organizations that require long-term security, compliance, centralized management, and professional support, Ubuntu Pro can therefore provide substantial operational value.
Ubuntu Pro extends the standard Ubuntu LTS experience with enterprise-focused security, maintenance, compliance, and management capabilities.
Organizations can adopt Ubuntu Pro without replacing their existing Ubuntu infrastructure, making it relatively easy to integrate into existing production environments.
Key Ubuntu Pro capabilities include:
- Up to 10 years of security maintenance
- Up to 15 years with Ubuntu Pro Legacy
- Security coverage for more than 36,000 open-source packages
- Kernel Livepatch
- Expanded Security Maintenance
- CIS, FIPS, and DISA-STIG support
- Landscape centralized management
- Optional 24/7 Canonical enterprise support
- Public cloud support for AWS, Azure, and Google Cloud
For organizations running business-critical Ubuntu infrastructure, Ubuntu Pro can be an important part of a long-term Linux security and lifecycle management strategy.
Because licensing conditions, service coverage, and pricing may change over time, organizations should always verify the latest information on Canonical’s official Ubuntu Pro pricing page before making a purchasing decision.
