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.

Quotes from Members

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

Pros

"The solution has different options that can be used to differentiate DDoS attacks."

"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."

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

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

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

"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."

"Cloudflare DDoS mitigates DDoS attacks."

More Cloudflare One pros

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"The most important aspect, in general, is that the price is suitable for most clients."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"The DDoS protection features are valuable."

"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."

"This is a hybrid solution."

"It is a very efficient and robust appliance."

More Corero pros

Cons

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

"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."

"Operating and tuning the product is difficult."

"Feedback could be enhanced."

"Our customers no longer use Cloudflare because its service is subpar."

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

"The initial onboarding was causing us some confusion."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

More Cloudflare One cons

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

"Lacks international presence."

"It could use support in Spanish."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."

"The product must provide more Layer 7 capabilities."

"Juniper is known in our country, but it is not very popular."

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

Pricing and Cost Advice

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

"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 prices are slightly expensive."

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

"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 pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The solution's pricing lacks transparency."

"The solution is not that expensive."

"Its price is normal."

"The price of Corero is affordable."
