Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
5.5
Portnox enhances security and efficiency, offering cost-effective NAC solutions with easier management compared to Cisco ISE or Aruba ClearPass.
Sentiment score
7.9
ThreatLocker Zero Trust boosts ROI by blocking threats, reducing risks, and enhancing security with seamless integration and quick adaptation.
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
If something were to happen without ThreatLocker, the cost would be huge, and thus, having it is definitely worth it.
Tier 1 IT Engineer at a retailer with 11-50 employees
The main return on investment is peace of mind, knowing that with ThreatLocker on any endpoint, it will almost always block all malicious code or exploits, even zero-day exploits.
Project Engineer at Lutz M&A, LLC
It keeps malware, Trojans, and ransomware at bay.

It seems to primarily operate on the endpoints rather than at a central location pushing out policies.

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.

Supervisor, Client Security at a consultancy with 11-50 employees

Room For Improvement

Portnox needs interface, integration, and support improvements; licensing, cloud reliance, and user convenience issues impact user satisfaction.
ThreatLocker could improve by enhancing training, UI, reporting, integration, and support to address approval and update challenges.
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.

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

ThreatLocker offers a cost-effective Zero Trust solution with flexible pricing, appreciated for transparency and easy setup across clients.
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
After conversations with other partners, it became clear we underpriced it initially, which caused most of our issues.
Director, Managed Services at a consultancy with 11-50 employees
We are moving towards the Unified solution, where they basically bundle everything together, providing us better stability with the ability to bring in new product offerings without having to go back to the customer and say, 'This is going to cost you.'
Supervisor, Client Security at a consultancy with 11-50 employees
I had a really good deal at the time, and it continues to be cost-effective.

Featured Reviews

Reviewer921606 - PeerSpot reviewer
Sr. Cloud Security Architect at a tech services company with 11-50 employees
Centralized access control has simplified operations but still needs more flexible on‑prem options
Portnox has design considerations that limit its applicability. If you are in a highly regulated industry with mandates requiring the solution to be completely on-premises, Portnox does not work at all. I do not think they position their products for those industries. Even for non-heavily regulated industries, if you want a self-sufficient system within your own premises, there are design constraints because at some point you must reach out to Portnox infrastructure in the cloud, and if that is unavailable, it suffers. For example, on deep-sea oil rigs without proper connectivity, it struggles. I am not sure they want to enter that particular business segment, as it may not align with their value proposition. I cannot blindly select this product and deploy it everywhere; I must make deliberate decisions first. Portnox could improve by reducing its heavy reliance on the cloud. While I do not think they want to eliminate this aspect, a complete solution for regulated entities would include some on-premises setup that is self-sufficient and does not depend on the cloud. This is the most important improvement. Second, Portnox already has a robust integration ecosystem with many vendors, but not all. Even when integration exists, the extent varies, particularly regarding vendor-specific attributes. I have never faced challenges because my security tools and stack have been standard: Cisco, Aruba access points, Cisco switches, and UniFi, all of which work well with them. However, there is room for deeper integration when compared to tools like Cisco ISE and Aruba ClearPass. Their offerings are clear, easy to onboard, and their day zero and day one onboarding activities are streamlined and straightforward. They share best practice checklists that make configuration simple.

Supervisor, Client Security at a consultancy with 11-50 employees
World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.
