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.

Enginner at Millennium Information Technologies

Has faced challenges with configuration, taking actions, and learning curve but benefits from centralized management and good technical support

We have deployed Cisco Secure Email Threat Defense in two customer environments. It is still in development as a new product. Some customer requirements, such as sending logs to a Syslog server, are limited as ETD only supports sending audit logs. Customers have requirements for other system logs as well, which should be developed from their side. Another customer request is to restrict the IPs that can log in, which cannot be done from Cisco Secure Email Threat Defense yet. Any user with login details can log in. We can restrict the IPs in Cloud Mail Gateways, but not from Cisco Secure Email Threat Defense. It would be beneficial to improve this feature. Cisco Secure Email Threat Defense can take actions, such as requesting O365 to quarantine mail. In that case, the customer requires notification to the recipient from Cisco Secure Email Threat Defense. This option would be valuable if available. The real-time threat intelligence of Cisco Secure Email Threat Defense is an AI-based classification. It took one to two months to optimize the classification, but we still experience some false positives. Reducing the learning period would be beneficial. 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. Reducing the learning time would be much better. Additional features desired in the next release include IP restrictions and user logging IP restrictions, ensuring only the customer environment can log in to Cisco Secure Email Threat Defense. Logs forwarding needs improvement as currently it only has audit logs. In Cloud Mail Gateway, we can create an IPsec tunnel to forward logs. However, in Cisco Secure Email Threat Defense, there is no option, and we must do API integration to send logs. Only SIM can get logs; Syslog cannot retrieve them.

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'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."

"It is a stable solution."

"Cloudflare, in my opinion, was easy to implement."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"I'm very satisfied with the environment and the dashboard."

"The blocking feature is very good."

"It's a perfect solution from my perspective; it's easy to understand and easy to configure."

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

More Cloudflare One pros

"I would say it's very comprehensive, with multiple antivirus OEMs, virus encrypt features, encryption, and more."

"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."

"Cisco's technical support is very good."

"Secure Email Threat Defense's scalability is good."

"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."

"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."

More Cisco Secure Email Threat Defense pros

"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."

"There are no wasted extras and the interface is really simple."

"It is a very scalable solution."

"The product is easy to manage in terms of configurations."

"The anti-spam aspect of the solution is its most valuable feature."

"The most valuable feature is that it protects from spam."

"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."

"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."

More SonicWall Email Security pros

Cons

"I would like them to include a VPN feature to provide a secure connection to the data center."

"The initial onboarding was causing us some confusion."

"Feedback could be enhanced."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"For the topic of improvement, providing some training material is one of my suggestions."

"They don't have a person to provide support for customers using the solution under their free plan."

"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."

More Cloudflare One cons

"The pricing could always be better."

"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."

"This solution could be improved by integration with Sandbox."

"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 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."

"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."

More Cisco Secure Email Threat Defense cons

"The reporting needs improvement."

"The pricing could be improved."

"Load balancing is not stable."

"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."

"I am not satisfied with phishing protection, as it falls completely under the email domain security."

"SonicWall Email Security is scalable, but the price per license is expensive."

"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."

More SonicWall Email Security cons

Pricing and Cost Advice

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

"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 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."

"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 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."

"The platform offers a yearly license."

"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."
