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

"There are a lot of filters for scam emails and things like that work out of the box. You can also use the antivirus features. I like its features."
"It does a great job of preventing spam, malware, and ransomware. I can only go by what people have told me and what I've seen, but I have not seen spam in a year and a half to two years in my own company mailbox. And there are not a lot of catches where it's catching something that should have gotten through, either."
"Cisco Secure Email is a budget-friendly solution."
"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."
"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."
"The technical support from Cisco is perfect."
"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."
"The product blocks spam emails."
"It is stable and reliable."
 

Cons

"The areas of Cisco Secure Email that could be improved or enhanced are the slowness in the console."
"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."
"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."
"I would like them to add some clustering or high availability features."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"There could be additional DLP functionality for it."
"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."
"We use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"The solution could be less expensive."
 

Pricing and Cost Advice

"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."
"I rate the product price as six on a scale of one to ten, where one means it is a very expensive tool."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"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."
"It is a reasonably priced solution."
"As per market availability, this solution is more expensive than other vendors."
