Portnox Cloud vs. On-Premise NAC: A Look at Total Cost of Ownership (TCO)

Hand holding bag of money

On-Premise NAC vs. SaaS NAC


Set-Up & Configuration: On-Premise NAC vs. SaaS NAC

Unlike traditional on-premise NAC solutions that require hardware appliances, software, and other on-premise elements, you can create your dedicated instance of Portnox Cloud in minutes.

Portnox Cloud has been built from the ground up to simplify policy configuration, allowing for deployment timelines that can be measured in hours. In contrast, traditional on-premise NAC deployments can be measured in weeks or months.

Set-Up Costs Eliminated with Portnox Cloud: Need for on-site appliances, need for third-party expertise, man-hours dedicated to systems training

Savings Value: HIGH


Scalability & Performance: On-Premise NAC vs. SaaS NAC

As a cloud service, Portnox Cloud eliminates the need for the capacity planning of on-premise NAC software or appliances. It also eliminates the need to expand capacity or upgrade appliances to meet future growth needs as required by traditional on-premise NAC.

Portnox Cloud can automatically control the virtual machine size and the scale up or down rules. Dedicated F5 load balancers are spun up as well as auto-scale, so you never have to be concerned with service performance or scalability – it will automatically expand as needed to meet demand.

Performance Costs Eliminated with Portnox Cloud: Man-hours dedicated to capacity planning, need for on-site appliance upgrades, need for local load balancing

Savings Value: MODERATE


Lifecycle Maintenance: On-Premise NAC vs. SaaS NAC

Another hidden cost of on-premise is maintenance. All you have to do is search the web – in most cases you’ll find that vendors have lengthy manuals that outline the painful steps and procedures necessary to keep the software or its associated appliances updated.

These upgrades often come with time limits that can force you to start over and re-do your work. Worse yet, one simple mistake during these upgrades can take your network down for many hours or days. And guess what? You often get to go through these upgrades multiple times per year.

With Portnox Cloud, never worry about software or hardware end-of-life, or costly, complex upgrades requiring hours and days of work and a never-ending checklist of to-dos. As a cloud-delivered service, Portnox Cloud is always running the most up-to-date version with the latest features and capabilities. At the end of the day, Portnox Cloud customers enjoy continuous service availability with ZERO lifecycle maintenance costs.
