Helps prevent security breaches but fails to improve in the area of AI
I have not noticed any impressive advanced threat protection mechanisms in the tool. I don't know if there are any AI features in the product. I don't know if there is any other technology embedded in the solution. Cisco Secure Email successfully mitigated potential email threats. My company has seen plenty of scenarios where Cisco Secure Email successfully mitigated potential email threats, spam emails, and fraudulent domains. The product is good for dealing with spam emails, and it can take care of more than 100 spam emails per day. A huge number of spam emails are monitored with the help of Cisco Secure Email. I would not recommend the product to other businesses because you need to have some kind of expertise in configuring and knowing a bit about the tool's GUI. The tool also lacks in the area of AI mechanics. If I would like to have an overview and review another solution, I would go for another product other than Cisco Secure Email. I can definitely suggest others to look at the product and review it, but I would also recommend that they compare it with the other solutions in the market. I wouldn't prioritize Cisco Secure Email over other tools. Either the support partner of the product or I take care of the tool's maintenance phase by looking into the configurations and doing some fine-tuning. I rate the tool a seven to eight out of ten.

Handles security, malware and spam of email systems
We use Email Security Gateway on email systems for handling security, malware, and spam.  The solution is easier to manage than FortiMail. You can implement policies easily.  The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very…

Quotes from Members

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

Pros

"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"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."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"Capital expenditure is a significant consideration, and the impact on major expenditures prompts a careful analysis before onboarding the new product."
"What I find the most valuable about Cisco Secure Email is that the logs are not that difficult to see even if you're not used to them. The logs are reasonably readable and diagnosing the problem is not too hard with them."
"The tool has a DLP solution which we can implement. Its database is updated regularly."
"The solution works well."
"It has the ability to tell us, after an email has been delivered, where else it went, once it got inside. Maybe it's something we wanted it to stop and it didn't stop it, but it notified us later that it was something that it should have stopped. It can give us a trajectory of all the other places that it went internally and it can tell us what files were transferred as well."
"The solution is easier to manage than FortiMail. You can implement policies easily."
"It helps reduce spam and phishing attacks."
 

Cons

"I would like to see features like AI since it is currently an area that the product lacks."
"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."
"One of the things that Cisco could improve on with IronPort is the support. Cisco doesn't really have enough engineers who have full, hands-on knowledge of IronPort. Knowledge of it is not something you can find easily compared to other security appliances."
"I would rate the stability a six out of ten. We had multiple issues with the stability."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"There could be additional DLP functionality for it."
"The user interface could be updated."
"They can do it better with web links, with the URLs. They have a technology called Outbreak but it doesn't work as well as we would like."
"The solution does not always effectively identify zero day spam and phishing, but once reported the correction occurs very quickly."
"Its pricing could be affordable."
 

Pricing and Cost Advice

"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 not that costly. We pay for the solution through a contractor and pay an annual fee."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"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."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"There are additional fees for adding features."
"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."
"The licensing was all transferred."
"Email Security Gateway's pricing is good."
