Executive SummaryUpdated on Dec 3, 2024

Cisco Secure Email and Cisco Secure Email Threat Defense provide advanced email security solutions. Cisco Secure Email is highlighted for its broad adaptability through numerous features, giving it a competitive edge in feature customization and management flexibility, whereas Cisco Secure Email Threat Defense excels in integrating with broader security ecosystems and offering advanced threat detection.

Features: Cisco Secure Email includes robust anti-spam measures, malware protection, and thorough integration with security protocols such as DKIM, DMARC, and AMP. It facilitates easy management and email customization, significantly reducing spam and improving filtering through Talos intelligence. Cisco Secure Email Threat Defense focuses on cloud-based threat intelligence and endpoint security integration with capabilities like Threat Grid and AMP that help identify and counteract malicious email threats proactively.

Room for Improvement: Cisco Secure Email requires better integration with third-party reporting tools and enhancements in CLI management. Users have noted challenges with rule-setting, desiring user interface improvements and better hardware reliability. Cisco Secure Email Threat Defense could enhance its collaboration with other tools, improve intuitive reporting, and develop a smarter search function. Both products would benefit from better phishing protection and additional sandboxing, along with cost reductions for broader accessibility.

Ease of Deployment and Customer Service: Cisco Secure Email offers versatile deployment options, supporting on-premises, cloud, and hybrid configurations, with seamless setup praised by users alongside reliable technical support. Cisco Secure Email Threat Defense is optimized for private, hybrid, and public cloud deployments, which can limit on-premises flexibility.

Cloud security has improved remote access and has reduced costs for smaller client sites
I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

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.

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support
We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. The learning curve shows that in the beginning, there are numerous false positives. For one month, we had to reclassify the false positives manually until the system learned. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

Quotes from Members

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

Pros

"What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection."
"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."
"Cloudflare is by far the most effective solution that I have come across."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"It is a stable solution."
"Cloudflare DDoS mitigates DDoS attacks."
More Cloudflare One pros
"The tool comes with AI features. It is good for clients who already use Cisco products due to integration."
"The filtering is definitely better at catching both spam and malicious messages, and there's a lot of extremely granular ability for setting up rules. You can do it the way you want to. The Microsoft solution tends to be pretty limited in how it allows some of that to be done."
"The advanced phishing protection and the integration with the awareness tool that Cisco has embedded into the solution to bring awareness to the customers about the dangers of phishing attacks and other things that come from email are the most valuable features."
"Cisco Secure Email Cloud Gateway has allowed our users to be able to concentrate on the emails that they do receive. Previously, our users had to deal with nine million additional emails across the organization, which is nearly 1,000 emails per user to have to deal with a month. That's a massive amount for our staff to deal with and probably several hours of their time. We have a lot of clinical staff, being a hospital. We want to make our staff as productive as possible. By removing a lot of that spam and phishing type emails, this allows them to do their job."
"My favorite feature of Cisco Secure Email is the threat intelligence capabilities, particularly its integration with Cisco Talos."
"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."
"Email service is one of the services that we offer at Galaxy, and Cisco ESA has improved our business so much that our customers want to maintain their business with us for email security, with over 500 domains on our email platform and improved profitability in everything."
"The added value of it is that every migration to a new version is initiated by the Cisco version itself, so that is a bunch of work that you don't have to do on the Cisco ESA system on-premise. As it becomes a safe platform, you don't need to invest anything in your own data center or in your upgrade path."
More Cisco Secure Email pros
"It has an efficient email filtering feature."
"This solution is easy to use."
"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's technical support is very good."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"It's very easy to deploy and configure."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
More Cisco Secure Email Threat Defense pros
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"The response time for support must be reduced."
"Cloudflare DDoS has poor technical support."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Our subscription plan for the solution has a limitation of bot signatures."
"The initial onboarding was causing us some confusion."
More Cloudflare One cons
"We didn't get any malware, but a few phishing emails, maybe one or two, slipped in."
"The primary areas for improvement are the pricing and the complexity of deployment."
"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."
"There are some concerns in the way the architecture is set up, making it an area where improvements are required."
"They can do it better with web links, with the URLs."
"If you are not a technical guy, it is hard to maneuver, but as soon as you work on it, it gets better and better. If there was a better way to know how to do things or how to find things, it would be good."
"We cannot manage multiple devices from a single UI."
"While Cisco offers excellent solutions and innovations, the pricing may not be suitable for everyone. The cost of the software is relatively high. In the current market, there are numerous competitive alternatives that focus on security, enterprise networks, and various other aspects. Cisco, being a comprehensive provider, extends its expertise across data, servers, storage, and security, making them a preferred choice for many enterprises. However, when it comes specifically to security solutions, there are other vendors that specialize solely in this domain, offering competitive options."
More Cisco Secure Email cons
"This solution could be improved by integration with Sandbox."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"The physical appliance has been discontinued, although the platform still exists."
"The search area has room for improvement."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"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."
More Cisco Secure Email Threat Defense cons
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The prices are slightly expensive."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"Pricing depends on your environment and which model you want to buy."
"I don't have the insights into it, but compared to different products, it seems to have a medium level of pricing."
"Licensing costs depend on how many users there are. It could range between $5 and $7 per month, per user."
"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."
"The product's price falls on the higher side when compared to the other products on the market."
"The licensing was all transferred."
"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."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
More Cisco Secure Email pricing and cost advice
"It is expensive compared to other vendors."
"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."
"The solution’s pricing is manageable."
