A stable solution that can be used for upgrades, vulnerability remediation, configuration, and standardization
I am using the latest version of Cisco OpenDNS. Users should prioritize the challenges that they have before implementing the solution. They need to be very clear about what they are looking for. Those parameters need to be defined, success criteria need to be checked, and then they can proceed with the solution that meets the requirements. Overall, I rate Cisco OpenDNS a nine out of ten.

Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Quotes from Members

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

Pros

"We use Cisco OpenDNS for upgrades, vulnerability remediation, configuration, and standardization."
"The platform is highly stable."
"Cloudflare has many features."
"Cloudflare is very straightforward."
"Generally, I am satisfied with this product."
"So far I use free tier and happy with it."
"The API gives us the ability to remote control our DNS settings."
"The tool is user-friendly."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
 

Cons

"The solution’s dashboard could be improved."
"The platform's DNS database area needs improvement."
"The pricing could be improved."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"For the services I am using, it is a bit expensive."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
 

Pricing and Cost Advice

"We pay a yearly licensing fee for the solution."
"The product is expensive yet cost-effective. I rate the pricing an eight out of ten."
"There are no additional costs beyond the standard licensing fees."
"The tool is a premium product, so it is very expensive."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The price is reasonable."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We are using the free tier of the solution."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"A free version of the solution is available."
