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.

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.

Clawback feature performs well but analytics and integration capabilities need improvement
The integration capability with other threat intelligence platforms is not optimal, as I have experienced difficulty in sending logs to our SIEM. Cisco Secure Email Threat Defense's flexibility could be enhanced while it mostly integrates with cloud solutions, but not on-premise. 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. Regarding room for improvement, the significant number of false positives should be addressed. The solution does not adapt to behavioral analytics and does not make changes when it sees a pattern.

Quotes from Members

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

Pros

"The blocking feature is very good."
"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."
"Cloudflare Access is a stable solution."
"Enables me to work from two locations."
"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."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
More Cloudflare One pros
"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"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."
"We rely heavily on antivirus protection, email content filtering, and authentication mechanisms to ensure compliance with email security. Regarding phishing attempts, while phishing protection features are crucial, we also emphasize user education as a critical defence. The intelligence services Cisco provides, such as the Cisco Intelligence Center, play a significant role in analyzing and validating threats, including phishing attempts, in our email security practices."
"Apart from the improvement needed to the filters, it was all good."
"The solution is valuable if you are looking for a security email gateway that provides you with the most services possible."
"Cisco Secure Email's most valuable is email certification."
"Comparing Microsoft Defender and Cisco's Email Secure service, partners have noted that while Microsoft Defender offers email security, the tool's additional layer of protection provides further defense against threats like spam and phishing emails."
"The malicious URL scanning, as well as the anti-malware features, have been really useful for us in our environment."
More Cisco Secure Email pros
"Secure Email Threat Defense's scalability is good."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"If you compare Cisco Secure Email Cloud Mailbox with the competition, in the competition you have to have one or two solutions together to address the customer's requirement, whereas Cisco Secure Email Cloud Mailbox is addressing everything, such as web domain and email protection."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"I highly recommend it as one of the best choices."
"The features and functionalities are much better than Microsoft's in-built Defender plan, and this product has helped us to protect our organization from any malware attack in the past."

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"Feedback could be enhanced."
"Lacks a VPN feature to provide a secure connection to the data center."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The onboarding process can be improved a little bit."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
More Cloudflare One cons
"The reporting functionality needs to be improved."
"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."
"I would like them to add some clustering or high availability features."
"Don't neglect that because if you just try to rely on Cisco support you're going to notice pretty consistent slowdowns."
"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."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"The discontinuation of physical hardware solutions is a significant area for improvement in Cisco Email Security Appliance. This decision has posed challenges as virtual appliances are now the only option, which may not be suitable for all industries. The uncertainty regarding the future of the hardware aspect of the solution is a notable concern."
"They could improve the filters. In my time at the company, there were several times we had to contact support to update the filters."
More Cisco Secure Email cons
"The solution is a bit expensive."
"The search area has room for improvement. When you go to the next page, it remains at the bottom of the current page that you're on. Also, under the reports section, it allows you to see any "convictions," but if you want to search for those convictions you have to remember when they all came in and go back and edit the search accordingly. You cannot click on the list of convictions to actually see if you had a spike at a certain time."
"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."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"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."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"The solution is a bit expensive. It could be cheaper."

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."
"The solution's pricing lacks transparency."
"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."
"The solution is not that expensive."
"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."
"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."
"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."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"It is a super big router that costs a few hundred thousand dollars."
"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'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."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"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."
More Cisco Secure Email pricing and cost advice
"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 feedback from vendors and customer is that it is expensive."
"The solution’s pricing is manageable."
"It is expensive compared to other vendors."
