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 product blocks spam emails."
"It provides good IT assistance."
"We like the in-built features, like the email filtering based on the IP and domain, and Cisco has its own blacklisted domains and IPs, which is very good because this filters around 70 percent of emails from spam and we are seeing fewer false positives with this."
"This is a great product with wonderful support."
"Users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification."
"It sends us reports, where we can see if there have been attacks, e.g. DDoS. If so, we can switch to a clean IP."
"There is a huge return compared to if we didn't have a gateway appliance, as far as blocking malicious emails."
"ATP has been the most valuable in improving our email security posture."
"It is stable and reliable."
 

Cons

"We have occasionally had hardware problems because we are using an appliance-based solution, but that might change. We may consider going to virtual systems."
"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."
"I would like them to add some clustering or high availability features."
"We would like to see more options for the customization of content filters."
"Cisco is not good in dealing proactively or even reactively, so we end up relying on partners."
"I would like more functionality and how to use it for Level 2 type staff. The biggest issue is it needs to be easier to use and navigate."
"The interface is dated. It has looked pretty much the same for 15 years or so. It would be helpful to be able to do everything from one spot. The centralized quarantine and reporting are completely separate from policy administration."
"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."
"The solution could be less expensive."
 

Pricing and Cost Advice

"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"The product's price falls on the higher side when compared to the other products on the market."
"There are additional fees for adding features."
"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."
"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 a relatively expensive option compared to other alternatives."
"In my previous organization, avoiding four instances of CryptoLocker within an estimated six month period is approximately $600,000 in lost time and effort. Our five year cost was about a million dollars, and the four outages that we had equated to 65 percent of that five year cost."
"The license was not per user, the license model was per feature. You could choose anti-virus, anti-spam, etc. It was feature-based and charged yearly."
