CV
Network Architect at IP Dimension
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.

Improved email threat visibility and security posture through adaptive reputation and analytics
I have experience with Cisco and other vendors like Sophos. I have more than 10 years of experience in this field. I worked with the Adaptive Reputation Management feature of SonicWall. Machine learning plays an important role in updating threat intelligence, particularly with SonicWall. The pricing for SonicWall Email Security is reasonable and budget-friendly. My overall rating for SonicWall Email Security is 8 out of 10 because, apart from the areas that need improvement, it was overall good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"I'm very satisfied with the environment and the dashboard."
"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."
"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."
"Cloudflare is by far the most effective solution that I have come across."
"Cloudflare DDoS mitigates DDoS attacks."
"Cloudflare Access is part of the Zero Trust philosophy."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"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 product is easy to manage in terms of configurations."
"Setup was easy. It took about 30 minutes."
"The pricing for SonicWall Email Security is reasonable and budget-friendly."
"The most valuable features are the anti-spam, anti-phishing, anti-virus, and anti-spoofing."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"It is a very scalable solution."
"The most valuable feature is that it protects from spam."
 

Cons

"The onboarding process can be improved a little bit."
"Cloudflare DDoS has poor technical support."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Cloudflare One is not very powerful, but for what we require, it is basic and sufficient."
"Feedback could be enhanced."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"For the topic of improvement, providing some training material is one of my suggestions."
"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."
"Previously, we had an issue with a faulty appliance and had to wait over two weeks for a replacement."
"Other than that, really I think the features are perfect, but attachment controls are so important it hurts the usability of the product."
"They should integrate the solution with third-party platforms."
"There could be definition updates included in the subscription."
"The pricing could be improved."
"I am not satisfied with phishing protection, as it falls completely under the email domain security."
"The protection level for email security isn't 100%. I'm still getting some spam and junk mail."
"A lot of spoofed emails are still coming to the end-user, so the configuration for this option needs to be improved."
 

Pricing and Cost Advice

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