SunilkumarNaganuri - PeerSpot reviewer
Enhanced device administration hindered by complex deployment and security limitations
Cisco Identity Services Engine (ISE) needs to improve the profiling preauthentication. They are very poor in asset classification and should focus on improving the preauthentication profiling, especially for NAC use cases. This will give them a roadmap for software-defined access (SDA) use cases and network segmentation. Threat detection capabilities are very weak. Additionally, the product is vulnerable and has many bugs.
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.
