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

"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."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"The solution is very configurable. It has enabled us to configure some specific filters to stop emails that general configurations didn't stop. It's a powerful solution. It can analyze a lot of emails simultaneously, with no problems of capacity or system load."
"The Cisco Secure Email Gateway, in my opinion, is a really good device."
"At one point, there was a zero-day attack. The Cisco appliance detected it and stopped it, helping us out. We avoided the attack and potential damage."
"Comparing Microsoft Defender and Cisco's Email Secure service, partners have noted that while Microsoft Defender offers email security, the tool's additional layer of protection provides further defense against threats like spam and phishing emails."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"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."
"It is stable and reliable."
 

Cons

"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."
"We have Microsoft and we have the E5 licenses, they have more EDR responses on certain emails. That's something that Cisco ESA on the cloud doesn't have. They don't do anything about MITRE attacks. They only detect if there is a malicious email or a threat and they remove it."
"Having Cisco Email Security as a standalone solution is not good enough. It needs to be combined with another solution."
"I would like to see features like AI since it is currently an area that the product lacks."
"The tool's pricing can be improved."
"The scalability must be improved."
"The solution does not have a strong outbound service. It should also integrate DLP."
"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."
"The solution could be less expensive."
 

Pricing and Cost Advice

"It's adapted to the market. It's similar to other vendors. We at least don't have many problems regarding that because Cisco is adaptable on that side. When we present the solutions to the customers, we tend to achieve the goals that the customer has in terms of the budget for such implementations."
"It is a super big router that costs a few hundred thousand dollars."
"Cisco Secure Email is expensive, but we get what we pay for."
"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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"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."
"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."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
