Sentiment score
4.1
Portnox enhances security and efficiency, reducing IT costs and workload through cloud-based management of device access and policies.
Using Aruba ClearPass has resulted in less engineering time compared to other products we've used.
Owner at Channelserve
The investment is huge for enterprise clients, but Aruba ClearPass makes processes easier.
Pre-Sales Consultant at a consultancy with 201-500 employees
If I compare this to an on-premises environment using Cisco ISE or Aruba ClearPass, it would require phenomenally large teams for infrastructure management.
Sr. Cloud Security Architect at a tech services company with 11-50 employees
If you were moving from a traditional on-premise NAC that was 100% managed by the IT department, there would be great savings in going to a cloud-based NAC with Portnox.
IT Infrastructure Manager at a tech vendor with 501-1,000 employees
Most customers feel value immediately upon deployment.
Product Manager at Applied Principles Limited

Sentiment score
7.0
Portnox is praised for its attentive, responsive customer service, efficient problem-solving, and minimal downtime during updates.
Portnox is one level up, as their customer support is outstanding.
Chief Digital Officer at Clarity AI
We have faced delays in the resolution of production issues after raising tickets, which impacts productivity.
Network Support Engineer at HDFC Life
If Aruba ClearPass is not working, then the organization is not working because this is the access control in the organization.
Presales Engineer, Solutions Architect
The main area needing improvement is the technical knowledge of support staff.
Senior Network Engineer at a tech services company with 11-50 employees
For very high severity issues where the entire office is non-functional, response time is within 30 minutes.
Sr. Cloud Security Architect at a tech services company with 11-50 employees
In terms of support, it is usually quite impressive. I usually get support in a matter of minutes or seconds, depending on the priority of the ticket.
Engineer at Applied Principles Limited
 

Scalability Issues

Sentiment score
8.1
Aruba ClearPass is praised for its scalability, supporting diverse user numbers and environments with flexibility in licensing and virtualization.

Portnox effectively scales to support thousands of endpoints, offering flexible and seamless cloud-based expansion to meet growing demands.
I believe the scalability of ClearPass is rated as ten out of ten.
Senior Security & Infra Technology Systems Engineer at BARQ Systems
Everything will be handled when you add new users because all configurations are deployed from the beginning.
Network Product Manager/ Senior Presales engineer at a computer software company with 501-1,000 employees
In our environment, ClearPass handles up to 100,000 users, which is better than some other NAC solutions like Fortinox that scale up to 25,000.
Network Engineer at a outsourcing company with 11-50 employees
We have never had any challenge based on a customer who has 1,000 devices versus a customer who has 30,000 devices; the feel is the same.
Product Manager at Applied Principles Limited
They ensure the backend can support it and do the provisioning while maintaining headroom and elasticity.
Sr. Cloud Security Architect at a tech services company with 11-50 employees
I rate scalability a ten; you simply pay and you get more.

Sentiment score
7.9
Aruba ClearPass is highly stable, praised for reliability, with occasional upgrade issues often due to misconfigurations, not system flaws.

Senior Enterprise Customer Solutions Specialist at a comms service provider with 1,001-5,000 employees
There are issues with some versions, especially in integrating with AD and SSL configurations over port sixty-three.
Network Support Engineer at HDFC Life
However, there are disadvantages when it is not on-premises, as every NAC suffers from it if it is not on-premises.
Presales Engineer, Solutions Architect
The product itself is available and its uptime is 100%.
Systems Analyst at a construction company with 1,001-5,000 employees
In the four years that I used Portnox, if it crashed or the server crashed, that would not have been more than once.
Information Technology System Administrator at a energy/utilities company with 10,001+ employees
If there is a version one and another version, the communication between the organization using it and Portnox should be firm so they can coordinate effectively.
Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees
 

Room For Improvement

Aruba ClearPass needs simplified licensing, UI, better integration, enhanced features, and improved support and documentation resources.
Portnox users seek flexible pricing, better integration, and enhanced features to improve functionality and user experience across organizations.
The language and policy enforcement mechanisms are not clear, making it difficult to use the product effectively.
Project Manager at a tech consulting company with 51-200 employees
It is also better to improve threat intelligence for built-in threat detection and prevention.
Network Engineer at a outsourcing company with 11-50 employees
A more streamlined menu of licensing options would be helpful.
Owner at Channelserve
Ideally, we should be able to search for any MAC address in the database, regardless of its authentication status, to see all its associated groups and potential conflicts.
President at TrackerSoft
When I reach the technical support, they give solutions that do not help me much, so I try to search the internet for other users' experiences to find solutions.
IT Project Manager at Xpress technologies
When I'm doing filtering at times, it doesn't filter the items properly.
Systems Analyst at a construction company with 1,001-5,000 employees
 

Setup Cost

Aruba ClearPass's complex licensing can be costly, with better affordability than Cisco, necessitating careful initial licensing understanding.
Portnox offers flexible, fair pricing with annual licenses, negotiable fees, and subscription-based options, appealing to larger organizations.
Achieving the best price requires careful selection from a menu of licensing options.
Owner at Channelserve
We cannot mix in prices, and of course, prices are going higher.
IT Network Operations Manager at KEDS
Aruba ClearPass is a premium product with higher pricing, which seems unnecessary given its complexity.
Project Manager at a tech consulting company with 51-200 employees
If you compare Portnox with all other well-known standard products, it is the cheapest.
IT Network Engineer at a tech vendor with 5,001-10,000 employees
The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe.
President at TrackerSoft
You are charged according to the number of users.
Senior Network Engineer at a tech services company with 11-50 employees
 

Valuable Features

Aruba ClearPass provides robust network access control with features like role-based management, third-party integration, and user-friendly configuration.

The most effective feature for us is the OnGuard feature.
Senior Security & Infra Technology Systems Engineer at BARQ Systems
It's notable how Portnox has improved operational efficiency.
IT Network Engineer at a tech vendor with 5,001-10,000 employees
It is a very robust application because three teams use that part: the network team, the security team, and the support people.
Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees
It is possible to find the MAC address in the switch, but in Portnox, it is very useful to see the status of those ports, and that increases our security.
Assistant System Engineer at Tata Consultancy

Featured Reviews

Darko Skurla - PeerSpot reviewer
Senior Enterprise Customer Solutions Specialist at a comms service provider with 1,001-5,000 employees
Role-based policies have simplified secure access control for all users and smart devices
I do not know about the functionality of Aruba ClearPass integration with a third party. If you ask me if there is support for Zebra and for different IoT devices, they have it. However, I do not know how to describe integration with other products. Aruba ClearPass can act as a RADIUS server and it can connect to the domain RADIUS server, for example. The biggest problem is when a customer does not know what they want with Aruba ClearPass. I can recommend Aruba ClearPass to other users because it is very stable. My review rating for this product is ten out of ten.
Maurice Mwaura - PeerSpot reviewer
Product Manager at Applied Principles Limited
Unified access control has improved compliance visibility and simplified passwordless access
There is work to be done when it comes to making the solution more seamless. For example, when a user is denied access, they would need a way to maybe self-resolve themselves, perhaps a way to generate a ticket on their own, something around resolutions. When it comes to users using the product, that is where good products are differentiated from products that are a bit of a challenge. Portnox has much to do in terms of their reporting. The generated reports need improvement. Things that other tools would say are normal are usually not present. For example, there is a page called NAS devices or NAS network that is able to show the switches that have been managed. Currently, there is no way of generating an easy report or an easy way of just generating something to tell the customer what they have been able to achieve so far. This is not done yet and is still very manual. I think there is work to be done there. More integrations around the various products being used would be beneficial. So far I have not encountered any major challenge. Where there was a challenge, I think support came in and helped us resolve. In fact, most of the challenges are not with the product; they are with the customer environment. I think that is just to update their documentation where they have come across a new vendor for easier integrations in the future.
