Email security has protected financial data and provides clear tracking for every branch message
The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console. I don't think it was a database error or something, but we feel some slowness in configuring DLP and other content filters compared to other consoles. It may have been due to on-premises, but it was much noisy at some times while configuring DLP. When we tried to configure a DLP policy, the console became much slower. In that case, we cannot see what had happened in the mail which was blocked at that time. It may take nearly an hour to get back to normal while configuring policies. That is the major issue in the product.

Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. 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. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"Compared with other mail security things, Cisco Secure Email was much better and easy to deploy also."
"There were detailed logs available. That was a seriously good feature... It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"Spam controls are excellent because they are a powerful feature that operates almost effortlessly."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"Overall, the ease of migration to Cisco's cloud email security from the on-prem solution was a positive experience."
"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."
"It's flexible. There are a lot of rules and policies that can be easily applied for certain employees or certain mailboxes."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection. If there is any kind of challenge it will come across through email."
"I highly recommend it as one of the best choices."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"Secure Email Threat Defense's scalability is good."
"The product offers protection, email security, anti-spam, and antivirus."
"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."
 

Cons

"Added cost and delay to the network traffic, but performance did remain stable."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The area of license renewal should be improved. We normally renew our license every year."
"We cannot manage multiple devices from a single UI."
"The pricing needs to be reconsidered or enhanced."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"I have some frustrations with the user experience in the interface, specifically with regard to making a list of people for whom I want to allow email access."
"The product's GUI for the dashboard needs improvement."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"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."
"We encounter issues while searching for missing emails."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"The pricing could always be better."
"The search area has room for improvement."
 

Pricing and Cost Advice

"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"The solution is expensive."
"As per market availability, this solution is more expensive than other vendors."
"The pricing is good."
"At times, we feel the pricing is a bit too high, but then, there is also room for discounts. We enjoy a lot of discounts, and that is why we are still with them. There are no costs in addition to the standard licensing fees."
"Compared to Cisco's on-prem service, the cost is the same, but you don't have to pay for the hardware and you don't have to maintain the system, as far as upgrades and hardware failures are concerned. It is cheaper to operate on their cloud service than it is to operate with their on-prem service."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"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."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
