Portnox and Intercept X Endpoint compete in the network access control and endpoint protection sector. While both are robust solutions, user preferences tilt towards Portnox for affordability and support, and Intercept X for superior security features.
Features: Portnox offers agentless operation, network visibility, and integration with Azure AD, Okta, and Google Workspace, enhancing security by limiting network access to essential users. Intercept X Endpoint provides centralized management, deep learning for threat detection, and synchronized security that links endpoint and firewall solutions.
Room for Improvement: Portnox needs to improve its pricing structure, cloud integration, and response time. Users suggest better integration with wireless solutions and specific vendor attributes. Intercept X Endpoint could enhance its user interface, address performance impact on older devices, and reduce CPU/RAM usage.
Ease of Deployment and Customer Service: Portnox is praised for simple integration without agents and quick support, with users noting its responsiveness. Intercept X Endpoint offers both cloud and on-premises deployment, with support noted as helpful but needing quicker resolution times.
Pricing and ROI: Portnox offers cost-effective licensing with transparency, saving time on IT resources for a beneficial ROI. Intercept X Endpoint, though priced higher, offers premium features providing substantial security ROI, with users willing to invest due to its threat mitigation capabilities.
I have seen a return on investment with Intercept X Endpoint.
If I compare this to an on-premises environment using Cisco ISE or Aruba ClearPass, it would require phenomenally large teams for infrastructure management.
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.
By automating the device containment and remediation processes, we save countless hours weekly.
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.
When you are in real deep trouble, you just want to get out of it; you don't need so many jargons.
The main area needing improvement is the technical knowledge of support staff.
For very high severity issues where the entire office is non-functional, response time is within 30 minutes.
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.
The customer support is scalable because if we take licenses for fifty machines and later purchase one hundred fifty more, we can increase our licensing with the support team.
The tool's scalability is good, and I would rate it an eight out of ten.
Intercept X Endpoint's scalability is good.
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.
Its infrastructure scales automatically in the background, eliminating concerns about capacity or backend upgrades.
It has a centralized cloud-based architecture, so we do not have to worry about other considerations such as local infrastructure or purchasing additional equipment.
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.
There should be a profile where I can see what files Sophos is scanning.
Intercept X Endpoint's anti-ransomware capabilities failed us during a bad attack, and just because of our own backup policies, we could restore our normal operations.
Intercept X Endpoint sometimes slows down machines due to high CPU utilization and significant RAM consumption during scanning.
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 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.
I would definitely request a UI refresh that makes the dashboard more modern and surfaces critical logs so they are easier to access in a pinch.
It is quite costly when measuring Intercept X Endpoint's protective capabilities against zero-day attacks.
The setup costs and licensing for Sophos Intercept X Endpoint are good.
The pricing of Intercept X Endpoint is a bit high.
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.
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 offers multiple features, including the Threat Analysis Center, remote run ransomware protection, and CryptoGuard.
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 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.
