Find out what your peers are saying about Cisco, HPE Aruba Networking, Fortinet and others in Network Access Control (NAC)."It's easy to manage and troubleshoot thanks to the lightweight components."
"It's a stable product."
"The product is a valuable solution within zero-trust architecture, enhancing network security and visibility."
"The most important feature is that this solution is agentless. So, you don't have to install any agents on endpoints."
"It's so easy to set up, you don't need outside assistance."
"I am impressed with the solution's voucher capability and authentication. The tool is integrated with Active Direct storage."
"Technical support was very helpful when we needed them."
"For the information security team, the security level was improved because it helped to manage and prevent rogue devices from connecting to the corporate network. The reporting was granular, and reports we scheduled for delivery on Portnox were useful during investigations and audits, especially in cases where the IP address changed."
"The scanning part, the agent part – that's the valuable aspect."
"It is a very good and user-friendly product."
"The tool's dashboard and reporting capabilities match our company's needs since we are able to modify the basic view to create a new dashboard, and it works out very well for our needs."
"This product has the best results in terms of the lowest number of false-positives and false-negatives."
"The solution has a lean and easy-to-use interface that is not confusing to first-time users."
"Tenable also helps us to focus resources on the vulnerabilities that are most likely to be exploited. And since it is continuously updated, it allows us to reevaluate quickly if there are new vulnerabilities found..."
"Initial setup was pretty straightforward."
"Tenable.sc is user-friendly."
"The solution did have some stability issues, however, all I had to do was restart it."
"The integration between Portnox CORE and Portnox CLEAR can be better. These are two different systems, and there is no unique console for both devices. Portnox CORE is agentless, whereas Portnox CLEAR is not agentless."
"Portnox CORE can improve on support for unmanaged switches (or hubs) and other brands of network devices. These kinds of devices are still in use in organisations, especially SMEs who cannot afford to buy a managed switch."
"It would be good to integrate Portnox CORE with CLEAR."
"The price could be better."
"Now, the way security is viewed, maybe including something like AI, to automate some of the things that are required to be done would be great."
"The product should consider more integration with vendors like Huawei. It should also improve visibility. The solution should offer a partner portal that can provide customers training on the in and out of the solution."
"One of the things for the on-premise is that sometimes you click on it and it takes a while for it to respond."
"Additional costs are associated with using the solution, as additional scanners are required for different endpoints connected to the Tenable Security Center. If Tenable Security Center could extract information from these scanners automatically rather than manually, it would enhance user-friendliness for customers."
"Tenable SC could be improved with additional connectivity to external company postures and the capability of managing and sustaining agents in the systems directly without additional platforms in the middle."
"The solution should include compliance-based scanning."
"Though the solution's technical support is responsive, they do take a lot of time, making it one of the solution's shortcomings that needs improvement."
"The solution's user interface has some issues."
"In terms of configuration, there is some level of flexibility that we are not able to achieve."
"The product could be user-friendly, and they could enhance the web application's security features."
"A good plugin editor would be a good additional option for the Security Center."
