    Lags in terms of grabbing phishing emails or phishing campaigns, though it has good scalability
    Armorblox is a cloud-based solution. The solution helped us improve the security, but we had a couple of issues regarding the operation. From an email security perspective, users or employees don't need gray mail or phishing emails in their email boxes. So, if the tool is not performing well in that area, then there's no sense in using that particular tool. Overall, I rate Armorblox a five out of ten.

    Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support
    We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

    Cons

    "Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
    "The search area has room for improvement."
    "The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned."
    "The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
    "Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
    "From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
    "The physical appliance has been discontinued, although the platform still exists."
    "The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration."
    "We encounter issues while searching for missing emails."

    Pricing and Cost Advice

    "On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
    "The solution’s pricing is manageable."
    "Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
    "It is expensive compared to other vendors."
    "The feedback from vendors and customer is that it is expensive."
