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

"It is doing its work. It is doing what it was actually designed to do. It has ensured we don't have business email compromises, and it has also ensured that our brand Galaxy is unique all year round."
"The reasons I chose Cisco Secure Email Gateway are the interface is - it's easy to use - and the support is great."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"It does a great job of preventing spam, malware, and ransomware."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"It provided a platform to sell a service to customers."
"The tech engineers are very knowledgeable."
"We chose Cisco Iron Port as it delivers strong email security protection and our company needed it to protect the company's email systems from spam, email viruses, .exe files, unwanted email from unwanted sender etc."
"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."
"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."
"The solution is stable."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"On ease of use, it rates very high."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
 

Cons

"The user interface needs some improvement to become more user-friendly. The graphics could be better. It's designed more for a technical user rather than a business user."
"Many smaller businesses opt for more cost-effective solutions, such as Gmail or Hotmail accounts, instead of investing in Cisco Secure Email, given its higher cost."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
"It would be nice to have an easier way to check on the health of the system, how stressed these appliances are. Sure, you can do it, but it would be helpful to have an easier way to do it, maybe even at a glance."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The configuration UI should be made more intuitive. Currently, it takes a while to understand how to do the basic configurations."
"The physical appliance has been discontinued, although the platform still exists."
"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 search area has room for improvement."
"We encounter issues while searching for missing emails."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"This solution could be improved by integration with Sandbox."
"The pricing could always be better."
"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."
 

Pricing and Cost Advice

"Cisco Secure Email is more expensive than other products. I rate it a five out of ten. There are no additional costs. You only need to pay the subscription amounts."
"It is a super big router that costs a few hundred thousand dollars."
"The price is significantly high."
"The pricing is good."
"It is a reasonably priced solution."
"Cisco Secure Email and the support are priced well. It's not cheap, but there are other solutions that offer less and cost so much. For example, Microsoft is more expensive than Cisco."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"The feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"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."
