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.

Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. 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. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

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 Access is a stable solution."
"Cloudflare is simple to use."
"Cloudflare is by far the most effective solution that I have come across."
"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."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
"Cloudflare DDoS mitigates DDoS attacks."
"Clover is the best product globally."
"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."
"Overall, it's certainly a very good idea to integrate another layer on top of Microsoft Advanced Threat Protection."
"Regarding stability, Cisco Secure Email Threat Defense is very stable."
"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."
"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."
"Secure Email Threat Defense's scalability is good."
"This solution is easy to use."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"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."
"SonicWall Email Security uses multi-layer cloud security."
"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."
"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."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"The most valuable feature is that it protects from spam."
 

Cons

"For the topic of improvement, providing some training material is one of my suggestions."
"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."
"Our customers no longer use Cloudflare because its service is subpar."
"I would like them to include a VPN feature to provide a secure connection to the data center."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"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."
"Feedback could be enhanced."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The pricing could always be better."
"The search area has room for improvement."
"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 physical appliance has been discontinued, although the platform still exists."
"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."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"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."
"Load balancing is not stable."
"Policy deployment could be time consuming and represents an area for improvement in SonicWall Email Security."
"They need well-trained partners in Nigeria."
"The protection level for email security isn't 100%. I'm still getting some spam and junk mail."
"The after-sale support needs improvement. They don't have representation in my country."
"Overall, this is a solution that provides good security but at a very high cost."
"The platform's control panel needs enhancement."
"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."
 

Pricing and Cost Advice

"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"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."
"The solution's pricing lacks transparency."
"The prices are slightly expensive."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"The feedback from vendors and customer is that it is expensive."
"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 platform offers a yearly license."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
"We have a two-year license subscription and the price is very high."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"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."
"Our customers purchase the solution's yearly license."
"I rate the application’s pricing a five out of ten."
