Portnox Reviews Summary
Author infoRatingReview Summary
President at TrackerSoft5.0Portnox serves as our primary network access control across offices, leveraging its excellent cloud-based integration with Meraki and Azure. However, troubleshooting becomes challenging when the same MAC address is used for different projects due to limited search functionality.
Senior Network Engineer at a tech services company with 11-50 employees4.0I've used Portnox for over three years to manage access control, finding it effective for enforcing policies and securing our network, though its complexity and limited user education sometimes hinder quick issue resolution and broader understanding.
Information Technology System Administrator at a energy/utilities company with 10,001+ employees4.0I initially used Portnox for network access control with our ISO 27001 implementation, effectively blocking unauthorized users and devices. I appreciated its detailed endpoint insights, though Wi-Fi integration could be improved, especially with UniFi controllers.
IT Infrastructure Manager at a tech vendor with 501-1,000 employees4.0We use Portnox as our main NAC for device protection across offices. Its cloud-based feature integrates easily with Meraki, requiring no maintenance from us. However, MAC address search limitations complicate troubleshooting, and while transitioning to it could offer cost savings, it hasn't reduced our workload yet.
Windows Server Administrator/ IT Support Officer at a financial services firm with 5,001-10,000 employees4.0I've used Portnox for over three years to authenticate users and devices, finding it robust and helpful across teams, though cloud-based authentication delays and manual updates can be challenging when stability issues arise.
Systems Analyst at a construction company with 1,001-5,000 employees4.5I use Portnox for dynamic VLAN assignment and network access control, appreciating its simplicity and ease of implementation. It effectively detects rogue endpoints, although its filtering system occasionally lags, not always filtering items correctly.
IT Network Engineer at a tech vendor with 5,001-10,000 employees3.5We use Portnox as our primary RADIUS server for wired and wireless authentication, benefiting from an easy-to-use dashboard. Previously, we used Aruba ClearPass but switched due to complexity and cost. Support is limited during Asia Pacific hours.
Network Security Specialist at Equity Bank Limited3.0We primarily use Portnox for network access control due to its simple UI and ease of deployment compared to Cisco. However, CORE can be sluggish in device authentication, prompting us to consider migrating to the more robust Portnox Clear.
