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.

Quotes from Members

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

Pros

"Overall, it is a very good product, and I'm very happy with it."
"The solution is valuable if you are looking for a security email gateway that provides you with the most services possible."
"Administration of the email domains and custom filters are easily done via the web interface."
"Cisco Secure Email is part of Cisco's extensive efforts and investments in technology, especially in the realm of cyber security. The product is one among many security solutions offered by Cisco."
"Introducing Cisco Secure Email Gateway systems was a set change for us and reduced the number of unwanted emails by a huge factor, a benefit that has continued from when we first got the devices until today."
"The logs are easily readable and help diagnose problems, although they can be difficult to find initially. The solution addresses our email security, but for the rest of our security, we would use multiple vendors. It covers everything through email, like antivirus, IDS, and IPS."
"It provides good IT assistance."
"The tech engineers are very knowledgeable."
"It is stable and reliable."
 

Cons

"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"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 solution needs to improve its advanced phishing filters. It is very good at filtering things which have bad reputations. However, when phishing or malicious emails are new or coming from a legitimate source, we don't feel that the solution is working."
"My opinion on the licensing of this solution is that it is a mess that needs sorting out. I am not particularly bothered by pricing as I administer it and make recommendations for people to buy or not to buy."
"More than a few steps are required to apply rules and these are not essentially intuitive."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"Cisco is already providing a very good environment with the IronPort solution, but there could be some more integration with other products. For instance, an integration with the EDR solution could be there to raise an alert."
"In some cases, detection is missed, leading to false positives where genuine emails are flagged as spam."
"The solution could be less expensive."
 

Pricing and Cost Advice

"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"It is a relatively expensive option compared to other alternatives."
"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."
"It is an expensive product. I rate its pricing an eight or nine."
"I rate the pricing a ten out of ten on a scale where one means it is less cost-effective, and ten means it is the most cost-effective solution."
"It is a super big router that costs a few hundred thousand dollars."
"The pricing for the Cisco Email Security Appliance involves recurring costs for licenses based on the contracted time frame, such as one year, three years, or five years. Renewals are required after the license expires."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
