Executive SummaryUpdated on Sep 21, 2025

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
6.1
Intercept X Endpoint is praised for its cost-effectiveness, ransomware protection, strategic impact, and overall network security satisfaction.
Sentiment score
4.8
Portnox CORE improved network visibility, security, and efficiency, reducing costs and enhancing decision-making through detailed analytics and automated features.
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.
 

Customer Service

Sentiment score
6.5
Intercept X Endpoint support is mixed; many praise responsiveness, though some experience delays, especially in sanctioned regions.
Sentiment score
6.7
Portnox customer service is responsive, but needs improvement in local support, ticketing, and technical training for better service.
Technical support from Sophos is rated as nine out of ten, which represents high quality.
There are issues with onboarding technical engineers to resolve problems, which causes delays.
The main area needing improvement is the technical knowledge of support staff.
They respond very immediately and provide detailed, amazing support.
I was seeing weird things, and they were able to explain things to me and help me quickly find a resolution.
 

Scalability Issues

Sentiment score
7.5
Intercept X Endpoint is praised for its scalability, ease of deployment, and adaptability for businesses of all sizes.
Sentiment score
7.5
Portnox is highly scalable and flexible, efficiently supporting many endpoints with its adaptable cloud-based licensing model.
The tool's scalability is good, and I would rate it an eight out of ten.
 

Stability Issues

Sentiment score
8.0
Intercept X Endpoint is stable and reliable, though some report occasional issues with updates and high resource usage.
Sentiment score
7.5
Portnox is stable but CORE faces issues; improved communication and support are needed, especially during updates and for older versions.
In terms of stability, I would rate Intercept X Endpoint an eight out of ten.
To improve Intercept X Endpoint performance, upgrades in RAM and other system features are needed.
The product itself is available and its uptime is 100%.
In the four years that I used Portnox, if it crashed or the server crashed, that would not have been more than once.
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.
 

Room For Improvement

Intercept X Endpoint needs enhancements in user management, integration, performance, customization, and support, while addressing high resource consumption.
Portnox should optimize licensing, integration, UI, partner training, support hours, Wi-Fi integration, and resolve cloud authentication delays.
There should be a profile where I can see what files Sophos is scanning.
Intercept X Endpoint sometimes slows down machines due to high CPU utilization and significant RAM consumption during scanning.
There is a licensing issue with Intercept X Endpoint; these licenses are user-based, and most of our customers require per-device licenses because they use one PC for multiple accounts, which presents a problem.
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.
They don't have much support during Asia Pacific hours.
 

Setup Cost

Intercept X Endpoint pricing varies by deployment, offering annual plans with discounts and flexible payments, valued for robust features.
Portnox pricing is considered balanced, offering scalable licenses, with mixed reactions to subscription-only plans and varying regional costs.
The pricing of Intercept X Endpoint is a bit high.
I would describe it as economical, but not much cheaper than other solutions.
If you compare Portnox with all other well-known standard products, it is the cheapest.
The pricing is a bit high, possibly due to the cloud features and running instances across regions like the US, Asia, and Europe.
You are charged according to the number of users.
 

Valuable Features

Sophos Intercept X Endpoint provides AI-driven security, centralized management, easy setup, and cost-effective protection with advanced threat detection.
Portnox offers scalable, intuitive network management with seamless integration and security compliance for efficient endpoint management and visibility.
The stronger the AI/ML in an endpoint, the better the protection against unknown threats.
Intercept X Endpoint is the only endpoint security product I know that provides content filtering and application controls.
Intercept X Endpoint has been stable, and I appreciate the centralized management and the reporting feature.
It's notable how Portnox has improved operational efficiency.
It is a very robust application because three teams use that part: the network team, the security team, and the support people.
It is very easy to implement on our current network hardware.

Featured Reviews

Suwandhi Suraweera - PeerSpot reviewer
Offers advanced filtering features and benefits from improved licensing and performance
There is a licensing issue with Intercept X Endpoint. Their licenses are user-based. Most of our customers use per device licenses, and they need per device licenses because they use one PC for multiple accounts. This creates a problem. There was one customer who complained about the slowness of PCs using Intercept X Endpoint. They use minor performance PCs, which causes their PCs to become slow.
Scott Kerr - PeerSpot reviewer
It is seamless and integrates well with our Azure setup
We use devices like PLCs and controllers, and when we receive a request to allow one on the network, we bypass typical authentication, associate it with a group account, and push it to a firewalled VLAN. However, problems arise when the same MAC address is requested for a different project. Our current system only finds authenticated MAC addresses, making it difficult to troubleshoot when the same device is used for multiple purposes. 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.
