Cisco Secure Email requires improvements in reporting, phishing detection, UI, documentation, integration, scalability, licensing, pricing, and database competitiveness.
The whole setup works well with Cisco access points and Cisco switches, but when you have multiple vendors in the environment, such as HP switches or access points like Aruba, you'll find they will not work well with Cisco Identity Services Engine (ISE).
Additionally, the product is vulnerable and has many bugs.
Pricing can be more expensive compared to other vendors, and there is a significant price gap observed, which doesn't seem justified by some specific features.

Cisco ISE offers three pricing tiers, with high costs and complex licensing, but provides extensive features and potential discounts.

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.
Kostas Karidas - PeerSpot reviewer
Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.
