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.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare is simple to use."
"Cloudflare, in my opinion, was easy to implement."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"The solution has different options that can be used to differentiate DDoS attacks."
"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."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"It provided a platform to sell a service to customers."
"The Cisco Email Security Appliance has enabled us to reduce spam by at least 30% compared to our previous solution."
"Anti-Spam and Advanced Malware Protection are the most valuable features... and we also have the option to block Zero-day attacks."
"Cisco Secure Email's most valuable is email certification."
"Apart from the improvement needed to the filters, it was all good."
"It saves a lot of time wasting, for example, phishing attacks distract a user's attention and forged emails waste a lot of time, and this solution helps protect user data."
"It's definitely worth looking at Cisco's cloud email security offering; it's surprisingly simple to get going with, it really is easier to use than the on-prem because of everything they have built into it, and it is surprisingly cost-effective."
"The solution works well."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"The most valuable feature of Mimecast Mailbox Continuity is real-time alerts."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"Mimecast has some good support services in place."
"The solution's performance is good."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"The setup was easy."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
 

Cons

"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Operating and tuning the product is difficult."
"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."
"Feedback could be enhanced."
"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."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Lacks a VPN feature to provide a secure connection to the data center."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"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 use the CLI for management, but it's not very good. It's based on Java and it's very difficult to use."
"The primary areas for improvement are the pricing and the complexity of deployment."
"The product's GUI for the dashboard needs improvement."
"Cisco Email Secure's pricing needs to be less. We have vendors who provide cheaper solutions with the same features."
"Cisco Secure Email can be improved from the administrator's point of view. Usually, you have to work with different areas, and they can try to make it easy for the administrator to use different functions."
"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 detection rates are an area for improvement."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"As for areas for improvement within Mimecast Web Security, I believe there is quite a lot that can be improved."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"Technical support has been slower than it was in the past, likely due to the pandemic."
"As a user, the user interface of the management console could be upgraded, for example."
"The installation is not so straightforward."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"Cloudflare Zero Trust Platform's pricing is good."
"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 prices are slightly expensive."
"The solution is not that expensive."
"The solution's pricing lacks transparency."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"We do annual licensing for Cisco Secure Email Gatewayand SMA together, and possibly SmartNet support. Packaged together, the cost is just under $38,000."
"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."
"It is expensive. I would rate it 2 out of 10, where 1 is the most expensive and 10 is the cheapest."
"In addition to the standard licensing, there is a cost for SMARTnet as well."
"It is a reasonably priced solution."
"There are additional fees for adding features."
"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."
"Two subscription options are currently offered: monthly and yearly. My suggestion is to opt for the yearly subscription as it can give some discount. The pricing isn't high as other cloud solutions are pricier than Microsoft's offerings."
"For what it is, the product is overpriced."
"The licensing costs are per-user for the product that you get with them."
"The product price is moderate. I rate the pricing a five out of ten."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It is a bit expensive."
"The solution is expensive."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
