4.8
Portnox CORE improved network visibility, security, and efficiency, reducing costs and enhancing decision-making through detailed analytics and automated features.

IT Head at a tech services company with 11-50 employees
The main area needing improvement is the technical knowledge of support staff.
Senior Network Engineer at a tech services company with 11-50 employees
They respond very immediately and provide detailed, amazing support.

Scalability Issues

Sentiment score
7.6
Forescout Platform is praised for scalability and adaptability, accommodating various environments and needs despite network issues.
Sentiment score
7.5

Stability Issues

Sentiment score
8.0
Forescout Platform is highly stable, with minor issues resolved quickly by effective support, earning user confidence in its performance.
Sentiment score
7.5
Portnox is stable but CORE faces issues; improved communication and support are needed, especially during updates and for older versions.
I would rate its stability as 9.5 out of ten.
Director, International IT Infrastructure Support & Information Security at a manufacturing company with 1,001-5,000 employees
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.

Room For Improvement

Forescout users seek enhanced memory management, detection, integration, reporting, interfaces, AI features, affordability, and improved support.
Portnox should optimize licensing, integration, UI, partner training, support hours, Wi-Fi integration, and resolve cloud authentication delays.
It would help if during integration, an admin user could check the password or credential used, as they currently cannot see the password after it is entered and saved.
Security Consultant at a tech vendor with 10,001+ employees
Forescout Platform could enhance its integration of AI to improve IoT and OT device security to better meet our needs.
IT Head at a tech services company with 11-50 employees
The console is a fat client, and a web interface would be preferable.
Director, International IT Infrastructure Support & Information Security at a manufacturing company with 1,001-5,000 employees
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.

Setup Cost

Forescout Platform is costly but offers scalable value, with flexible licensing based on devices and potential discounts available.
Portnox pricing is considered balanced, offering scalable licenses, with mixed reactions to subscription-only plans and varying regional costs.
Installing a physical box on each site can be expensive.

The overall pricing of Forescout Platform is reasonable for the functionality it provides.

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

Featured Reviews

AshishKumar Rai - PeerSpot reviewer
Security Consultant at a tech vendor with 10,001+ employees
Comprehensive visibility has strengthened endpoint control and automated threat response across networks
When it comes to improving Forescout Platform, I have faced some issues recently, particularly with the switch integration part. When integrating a switch, it asks for the vendor type, and often it does not match. For example, one series of HP switches may not be found in that vendor list. This leads to frustration because you have to check again with different HP models, and once you integrate a switch, you cannot edit the vendor list without removing it. Other issues are being worked on, particularly related to switch integration. I believe they will be fixed in the next upgrade or patch fix. There are no major issues, but the configuration changes needed for the switch model are necessary, and I think it would help if during integration, an admin user could check the password or credential used, as they currently cannot see the password after it is entered and saved.
Scott Kerr - PeerSpot reviewer
President at TrackerSoft
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.
