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

"It will take the blow rather than our applications should an attack occur."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare DDoS mitigates DDoS attacks."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"I'm very satisfied with the environment and the dashboard."
"This solution is easy to understand and easy to configure."
"Cloudflare Access is part of the Zero Trust philosophy."
"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"Secure Email Threat Defense's scalability is good."
"It has an efficient email filtering feature."
"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."
"Cisco Cloud Mailbox is used for copying emails, anti-spamming, and securing the company's email, and we really enjoy the anti-spamming capabilities as well as the rejecting of bulk emails, which we can customize by adjusting the variables, and it is very user-friendly."
"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."
"Setup was easy. It took about 30 minutes."
"According to our customers, the product's most valuable feature is the ability to detect spam and reduce phishing emails."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"SonicWall Email Security uses multi-layer cloud security."
"Behind the reason we chose SonicWall for my company is it has excellent packet analysis of normal and SSL encrypted traffic, application intelligence visualization and control, multiple Gigabit Ethernet LAN and WAN ports, flexible configuration and redundancy options."
"There are no wasted extras and the interface is really simple, so even if you don't have an IT background you can understand the working procedure and how systems are monitored."
"This solution provides very good email security that protects us against spamming and malware."
"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."
 

Cons

"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Cloudflare DDoS has poor technical support."
"Our subscription plan for the solution has a limitation of bot signatures."
"The initial onboarding was causing us some confusion."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"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 pricing could always be better."
"Customers will benefit greatly from monthly billing because the majority of customers today use the cloud, be it Office 365, or Google Cloud."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"We encounter issues while searching for missing emails."
"The physical appliance has been discontinued, although the platform still exists."
"I wouldn't recommend Cisco to others because I think Fortinet is better."
"Other than that, really I think the features are perfect, but attachment controls are so important it hurts the usability of the product."
"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."
"The pricing could be improved."
"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."
"The protection level for email security isn't 100%. I'm still getting some spam and junk mail."
"They need well-trained partners in Nigeria."
"The pricing could be improved."
 

Pricing and Cost Advice

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly expensive."
"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."
"It is expensive compared to other vendors."
"The solution’s pricing is manageable."
"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."
"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."
