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.

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.

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

"I'm very satisfied with the environment and the dashboard."
"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."
"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."
"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."
"This solution is easy to understand and easy to configure."
"Enables me to work from two locations."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare is simple to use."
"It has an efficient email filtering feature."
"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."
"The advanced threat analytics and URL filtering in threat detection are good features that are working well."
"I highly recommend it as one of the best choices."
"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."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"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."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"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."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"The anti-spam aspect of the solution is its most valuable feature."
"It is a very scalable solution."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"SonicWall Email Security uses multi-layer cloud security."
"The product is easy to manage in terms of configurations."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
 

Cons

"They don't have a person to provide support for customers using the solution under their free plan."
"The initial onboarding was causing us some confusion."
"The response time for support must be reduced."
"Cloudflare DDoS has poor technical support."
"Our customers no longer use Cloudflare because its service is subpar."
"Feedback could be enhanced."
"Lacks a VPN feature to provide a secure connection to the data center."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"This solution could be improved by integration with Sandbox."
"The pricing could always be better."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"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."
"Cisco Secure Email Cloud Mailbox can improve by adding advanced phishing, then the solution would become the best in the market. However, this could increase the price even more. Additionally, if CES with domain protection could be added it would be an even better solution."
"There could be definition updates included in the subscription."
"The platform's control panel needs enhancement."
"They should integrate the solution with third-party platforms."
"The pricing could be improved."
"Updates could be released more frequently."
"A lot of spoofed emails are still coming to the end-user, so the configuration for this option needs to be improved."
"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."
"Policy deployment could be time consuming and represents an area for improvement in SonicWall Email Security."
 

Pricing and Cost Advice

"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 of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"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."
"I rate the application’s pricing a five out of ten."
"We have a two-year license subscription and the price is very high."
"Our customers purchase the solution's yearly license."
"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."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"The platform offers a yearly license."
