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.

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks
Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Has consistently supported security needs for mid-sized teams with affordable deployment
I do not work with Cloud Secure Edge, CSE, or SMA apart from SonicWall NSA. I am not satisfied with phishing protection, as it falls completely under the email domain security. The customizable policy configuration does not help to tailor email security overall because our systems are not integrated with SonicWall Email Security. We are not using reporting and analytics because it requires completely different software. While all required features are available in SonicWall Email Security for SMBs and startups, we lack analytics features. They provide an option to purchase a complete separate product for analytics, but despite initially having purchased the paper license, due to technical limitations or changes, we cannot use that product. Now they require additional fees to access the analytics feature.

Quotes from Members

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

Pros

"Clover is the best product globally."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"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."
"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."
"Cloudflare Access is a stable solution."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Enables me to work from two locations."
"It will take the blow rather than our applications should an attack occur."
"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."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"I would rate Mimecast Email Security a nine out of ten."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"The setup was easy."
"The product is good. To date, we have not faced any challenges."
"Mimecast is pretty good, even if you're on Office 365."
"We like the content filtering and secure messaging features."
"We always get ROI from the product we are using; it is completely flexible and acceptable according to our security requirements over the last four years and currently."
"This solution provides very good email security that protects us against spamming and malware."
"It is a very scalable solution."
"SonicWall Email Security has benefited the company by preventing attacks, protecting us from threats such as ransomware and phishing, and notifying the IT team when phishing emails have been blocked."
"The most valuable feature is that it protects from spam."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"Setup was easy. It took about 30 minutes."
"There are no wasted extras and the interface is really simple."
 

Cons

"Our subscription plan for the solution has a limitation of bot signatures."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Operating and tuning the product is difficult."
"They don't have a person to provide support for customers using the solution under their free plan."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."
"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."
"External security features need 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."
"The solution is expensive in comparison to similar solutions."
"Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts."
"The solution is very expensive."
"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 solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"The price could be better, it should be reduced."
"Overall, this is a solution that provides good security but at a very high cost."
"The platform's control panel needs enhancement."
"The reporting needs improvement."
"A lot of spoofed emails are still coming to the end-user, so the configuration for this option needs to be improved."
"Updates could be released more frequently."
"SonicWall Email Security is scalable, but the price per license is expensive."
"The after-sale support needs improvement. They don't have representation in my country."
"I am not satisfied with phishing protection, as it falls completely under the email domain security."
 

Pricing and Cost Advice

"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 solution's pricing lacks transparency."
"The prices are slightly expensive."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that 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."
"It is a bit expensive."
"The licensing costs are per-user for the product that you get with them."
"It's an expensive solution."
"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."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
"The solution is expensive."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"We have a two-year license subscription and the price is very high."
"Our customers purchase the solution's yearly license."
"The platform offers a yearly license."
"I rate the application’s pricing a five out of ten."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."
