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 is simple to use."
"Cloudflare Access is part of the Zero Trust philosophy."
"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 will take the blow rather than our applications should an attack occur."
"Cloudflare DDoS mitigates DDoS attacks."
"This solution is easy to understand and easy to configure."
"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."
"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."
"From a functionality perspective, the platform is great."
"The strong point of the solution is that we hardly get any spam emails because of Cisco Secure Email."
"IronPort really helped with the mail filtering and load balancing between the Exchange servers they had."
"Because we scan products, and there is a lot of critical data, security is very important in these cases."
"Cisco IronPort mail security was very helpful by blocking threats, viruses, worms and Trojans from attacking the mail accounts and user PCs."
"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 system enables end users to manage their own whitelists/blacklists."
"The solution works well."
"It offers an easy initial setup."
"The initial setup is easy."
"URL inspection works pretty well."
"My advice to those considering this product would be to go for it."
"Email security is the most valuable feature of the solution."
"I have been satisfied with Mimecast Email Security as a good solution."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"If I had to mention one or two things that bring the biggest benefit, I would say the security of the emails and dealing with everything."
 

Cons

"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"Cloudflare DDoS has poor technical support."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Our subscription plan for the solution has a limitation of bot signatures."
"They don't have a person to provide support for customers using the solution under their free plan."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The initial onboarding was causing us some confusion."
"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."
"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."
"The pricing needs to be reconsidered or enhanced."
"It is not user-friendly, and it is quite complicated. So, it should be more user-friendly."
"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."
"We have been struggling in the last month with Cisco encryption and with the S/MIME encryption. I don't know if it is an issue on our side or if these features of the solution are not working very well."
"I would like more functionality and how to use it for Level 2 type staff."
"I would like to see sandboxing for email, where suspicious emails received by the system are analyzed through online services."
"Its pricing can be improved. It is a bit expensive."
"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."
"The detection rates are an area for improvement."
"Certainly, the primary area needing improvement is Mimecast's customer support. Our experience as Mimecast customers has been less than satisfactory. Even when raising a priority ticket, the response time is unacceptably long, often taking around five to six hours. This level of service is disappointing. Additionally, there have been recurring service disruptions in the UK region, leading to extended email delays due to various service issues. This year alone, we've encountered such problems on approximately four occasions."
"The product's interface could be improved to be more user-friendly."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"The solution is expensive in comparison to similar solutions."
"Technical support has been slower than it was in the past, likely due to the pandemic."
 

Pricing and Cost Advice

"The solution is not that expensive."
"The prices are slightly expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"I would rate the pricing a ten out of ten, where one is cheap, and ten is expensive."
"Cisco Secure Email is not expensive, and licensing costs are yearly."
"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."
"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."
"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."
"The product's price falls on the higher side when compared to the other products on the market."
"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 a reasonably priced solution."
"For what it is, the product is overpriced."
"The customers can select the license packages as per their requirements."
"Its price is in the middle range. It is a structured licensing model where there are various components that you can add or choose to add or not."
"It is a bit expensive."
"The product price is moderate. I rate the pricing a five out of ten."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"The licensing costs are per-user for the product that you get with them."
"The solution is expensive."
