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

"Cloudflare, in my opinion, was easy to implement."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Enables me to work from two locations."
"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 part of the Zero Trust philosophy."
"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."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"On ease of use, it rates very high. It's something that I was able to get into without really looking at any documentation. I wanted to see what it felt like before I started looking at any documentation on how to use it, and it was very easy to use. It works very smoothly. The user experience is very intuitive. They did an amazing job on that."
"The features and functionalities are much better than Microsoft's in-built Defender plan."
"Cisco Secure Email Threat Defense's best features include user management of graymail, enhancing security awareness by allowing users to manage cold calls, sales-based items, and ensuring email compliance."
"Cisco Secure Email Cloud Mailbox can handle a complete portfolio, which is required to protect any kind of attack coming from emails. However, it does not have advanced phishing, but it is available through Cisco. 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. If there is any kind of challenge it will come across through email."
"It's very easy to deploy and configure."
"This solution is easy to use."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The most valuable feature of SonicWall Email Security is the blocking of emails using keywords. If there are any particular keywords in the subject, that we want to block from receiving from a particular person we can do it. Additionally, the blocking of emails is easy. we can release that one and we can block some of the keywords also like that."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"The product is easy to manage in terms of configurations."
"SonicWall Email Security uses multi-layer cloud security."
"SonicWall Email Security uses multi-layer cloud security."
"It is a very scalable solution."
"Setup was easy. It took about 30 minutes."
"The most valuable feature is that it protects from spam."
 

Cons

"The initial onboarding was causing us some confusion."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Feedback could be enhanced."
"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."
"Cloudflare DDoS has poor technical support."
"They don't have a person to provide support for customers using the solution under their free plan."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"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 solution is a bit expensive."
"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 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."
"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 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."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
"There could be definition updates included in the subscription."
"The technical support from the company is not always very good at solving issues, but they offer access to a good community of users where problems are easily solved."
"The reporting needs improvement."
"They should integrate the solution with third-party platforms."
"The pricing could be improved."
"Policy deployment could be time consuming and represents an area for improvement in SonicWall Email Security."
"I am not satisfied with phishing protection, as it falls completely under the email domain security."
"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"
 

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."
"Cloudflare Zero Trust Platform's pricing is good."
"The solution is not that expensive."
"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."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"It is expensive compared to other vendors."

"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."
