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.

Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

Quotes from Members

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

Pros

"ATP has been the most valuable in improving our email security posture."
"I can customize the configuration and policies."
"Because we scan products, and there is a lot of critical data, security is very important in these cases."
"It has an intuitive, clear graphical interface where you can deploy your policies and understand the overall flow. There are a lot of things that you cannot handle on the graphic interface, like message filters. For this, you need to go to a lower level where you have more power, like command line interface. So, this solution has the best of both worlds. There are not a lot of bells and whistles. It is more practical with access to most features that you can configure."
"The system enables end users to manage their own whitelists/blacklists."
"Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number..."
"The tool's most valuable feature in preventing security breaches revolves around the area of malware protection that the product provides."
"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."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"Cisco's technical support is very good."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"It has an efficient email filtering feature."
"On ease of use, it rates very high."
 

Cons

"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."
"The hardware is not up to the mark. Two to three times a year we have complete downtime."
"The graphical user interface is not user-friendly like other vendors. I find it very difficult at times to find some options on the UI."
"We cannot manage multiple devices from a single UI."
"I have some frustrations with the user experience in the interface, specifically with regard to making a list of people for whom I want to allow email access."
"The solution does not have a strong outbound service. It should also integrate DLP."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The management features of the product are not up to date."
"The solution is a bit expensive. It could be cheaper."
"The search area has room for improvement."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The pricing could always be better."
"The physical appliance has been discontinued, although the platform still exists."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
 

Pricing and Cost Advice

"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."
"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 licensing is a mess and needs sorting out. I am not really concerned about the pricing because I only make recommendations, not buying decisions."
"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."
"Pricing depends on your environment and which model you want to buy."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"The feedback from vendors and customer is that it is expensive."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
