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

"The platform is highly stable."
"We use Cisco OpenDNS for upgrades, vulnerability remediation, configuration, and standardization."
"Generally, I am satisfied with this product."
"Cloudflare is very straightforward."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."
 

Cons

"The platform's DNS database area needs improvement."
"The solution’s dashboard could be improved."
"The pricing, setup cost, and licensing for Cloudflare are a bit on the higher side overall."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"There should be a specific price list for enterprise-level customers."
"The pricing could be improved."
"Several features that I think is essential is not available in the free and business package."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
 

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."
"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."
"The product's pricing is minimal compared to other products."
"We are using the free version."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"We don't have any issues with the price."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
