The Potential Pitfalls of Cisco ISE Licensing
What does Cisco ISE licensing look like?
Cisco Identity Services Engine (ISE) licensing is structured around enabling various features and capabilities within the ISE platform, which is a comprehensive security policy management and control solution. It provides the ability to see and control users and devices connecting across your entire network infrastructure. Cisco ISE offers a wide range of functionalities including secure network access, profiling, posture, guest management, BYOD (Bring Your Own Device) support, and more.
Cisco ISE licensing is modular, allowing organizations to purchase the specific types of licenses that meet their needs. The licensing model has evolved over time, so it's important to consult the latest Cisco documentation or a Cisco sales representative for the most current information. However, as of my last update, the licensing could be broadly categorized as follows:
1. Base License
- Network Access Control (NAC): Provides the ability to enforce access policies on endpoints, controlling which devices are allowed to connect to the network.
- Guest Access: Supports guest management capabilities, allowing visitors to access the internet or limited network resources.
- Link Encryption (TrustSec): Facilitates secure communication between devices on the network.
2. Plus License
- Advanced Endpoint Context: Offers enhanced visibility into the devices connecting to the network, including profiling and endpoint protection service integration.
- BYOD Support: Provides tools and workflows necessary to support a Bring Your Own Device policy, including device registration and device compliance checks.
3. Apex License
- Posture Assessment: Enables the evaluation of devices to ensure they comply with security policies before granting them access to the network. This can include checking for antivirus software, system updates, and more.
- MDM/EMM Integration: Integrates with Mobile Device Management (MDM) and Enterprise Mobility Management (EMM) solutions for comprehensive device management capabilities.
- VPN Access: Supports secure remote access through VPNs, applying consistent policy enforcement regardless of user location.
4. Device Administration License
- Specifically for TACACS+ (Terminal Access Controller Access-Control System Plus), this license enables device administration, allowing for centralized control over who can access network devices and what commands they can execute.
Licensing Models
- Perpetual Licensing: You pay a one-time fee to use the software indefinitely.
- Subscription Licensing: Offers access to the software and support for a specific period. This model may include options for different terms (e.g., 1-year, 3-year, 5-year subscriptions).
Deployment Options
- Physical Appliances
- Virtual Appliances
- Cloud Services
How to Purchase
Licensing can be complex, and Cisco often updates its models to reflect new features and market demands. It's recommended to contact a Cisco sales representative or a certified partner for the most accurate and tailored advice, including potential bundles, promotions, or discounts that may apply to your situation.
Remember, the specifics of Cisco ISE licensing, including costs and the exact features included with each license type, can change. Always refer to the latest official Cisco documentation or contact Cisco directly for the most current information.
Is Cisco ISE licensing perpetual or subscription-based?
Cisco Identity Services Engine (ISE) offers both perpetual and subscription-based licensing options, allowing organizations to choose the model that best fits their budgeting and operational needs. Here's a brief overview of both types:
Perpetual Licensing
- Perpetual licenses mean that once you purchase the license, you own it indefinitely for the version of Cisco ISE you have deployed. You pay a one-time fee and can use the license forever.
- However, while the license itself does not expire, access to software updates, support, and maintenance services typically requires an additional, ongoing subscription to Cisco's Software Support Service (SWSS). This means that while you can continue using your version of ISE without additional license fees, you might need to pay for SWSS to keep the software up to date and to receive technical support.
Subscription Licensing
- Subscription licenses are paid for on a recurring basis and are valid for a set term, such as 1, 3, or 5 years. This model includes not only the use of the software but also access to software updates, support, and sometimes additional cloud-based features that might not be available with perpetual licenses.
- Subscription licensing can offer more flexibility and lower upfront costs compared to perpetual licenses. It also ensures that you always have access to the latest software versions and support from Cisco.
Choosing the Right Model
The choice between perpetual and subscription licensing depends on several factors, including budget considerations, the need for flexibility in scaling up or down, and the desire to always have access to the latest features and updates. Subscription models can be more cost-effective in the short term and offer the advantage of including ongoing support and updates. Perpetual licenses might appeal more to organizations that prefer a one-time capital expenditure and have a stable, long-term need for the product, although they need to consider the additional cost for SWSS to keep the software supported and updated.
Given the evolving nature of Cisco's licensing models and the introduction of new features and services, it's important to consult with Cisco or a certified Cisco partner to get the most current information and tailored advice for your specific situation. They can provide insights into the total cost of ownership (TCO) for each licensing model over your expected usage period and help you understand the implications of each option for your organization's needs.
Are there potential hidden costs to Cisco ISE licensing?
When considering Cisco Identity Services Engine (ISE) licensing, it's important to be aware of potential hidden or additional costs that might not be immediately obvious. These costs can affect the total cost of ownership (TCO) and should be factored into your budgeting and planning processes. Here are several areas where additional costs might arise:
