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

"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"It's flexible. There are a lot of rules and policies that can be easily applied for certain employees or certain mailboxes."
"The most valuable features of the Cisco ESA have to do with the intelligence they provide us, as they respond quickly to any phishing attacks and threats on the system."
"IronPort allows visibility into the problem and an easy way to pinpoint policy offenders."
"Cisco Secure Email is a budget-friendly solution."
"It provided a platform to sell a service to customers."
"The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution."
"The most significant enhancement we've gained is in terms of security through the upgrade we received."
"It is stable and reliable."
 

Cons

"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."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"The primary areas for improvement are the pricing and the complexity of deployment."
"I would like them to add some clustering or high availability features."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"The UI is definitely one area of improvement because it doesn't match other interfaces and the navigation can be a little clunky."
"The reporting functionality needs to be improved."
"I would rate the stability a six out of ten. We had multiple issues with the stability."
"The solution could be less expensive."
 

Pricing and Cost Advice

"You're going to get what you pay for. If you're not willing to pay the price of Cisco, you're not going to get a product that's as good as Cisco. I don't think Cisco is overpriced, because for the last two years I've been comparing it to Microsoft and Cisco has been cheaper and given us more features."
"The solution is expensive."
"We were using Proofpoint and then we switched to Cisco... reportability was one of the main reasons we switched, but the biggest one was cost. If you can get an equivalent functionality for a better price it's wise to do so. That's what our primary decision came down to: We could get equivalent functionality at a lower price point."
"There were no other costs in addition to the standard licensing fees."
"The licensing was all transferred."
"It is a reasonably priced solution."
"It is an expensive product. I rate its pricing an eight or nine."
"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."
