    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.

    Quotes from Members

    We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
     

    Pros

    "Armorblox is a scalable solution."
    "Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
    "Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
    "The solution is stable."
    "The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."
    "The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
    "Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
    "It has an efficient email filtering feature."
    "I highly recommend it as one of the best choices."

    Cons

    "Armorblox lagged in terms of grabbing phishing emails or phishing campaigns."
    "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."
    "From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
    "The solution is a bit expensive. It could be cheaper."
    "There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
    "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."
    "Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
    "I wouldn't recommend Cisco to others because I think Fortinet is better."
    "The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."

    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."
    "The feedback from vendors and customer is that it is expensive."
    "It is expensive compared to other vendors."
    "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."
