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.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.

Quotes from Members

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

Pros

"Centralized, full-featured DNS."
"The setup and configuration is also easy to perform and their support is excellent."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"Their free account offers an awful lot of functionality and savings alone, before you get on to the minimal $20 a month for a Pro account which comes with its own great list of features."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"We have researched them all, and it's a good solution all around."
"The solution is very user-friendly and very easy to use."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The product allows the users to adjust the thresholds."
"It is a user-friendly product in terms of monitoring and updating policies."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"Packet inspection has been effective for mitigating DDoS attacks."
"I rate the scalability as ten out of ten."
"It operates on a logical level, providing a comprehensive and centralized way to manage your network resources."
"The solution is very stable; there are no bugs or glitches, it doesn't crash or freeze, and it's reliable."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"The solution is robust as it covers everything we want to do and is stable, so we're happy enough with it. We have had no problems so far. Everything is great."
"The solution is very stable and reliable."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"NSX is good in managing security or controlling the security and the access control for each single VM."
 

Cons

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"There might be helpful if there was some web application firewall feature."
"The product needs to improve its automation."
"There are some issues with the CDN services."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"Alerts and reporting features must be improved."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The web interface could be much better."
"The solution can be a little more user-friendly and it can be more affordable."
"The product’s pricing needs improvement."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."
"The solution can improve by making it more straightforward, easier to install and maintain in the environment."
"They could do more with cloud management."
"The initial configuration and integration within our existing environment were not easy. The configuration process was a bit complex, specifically during the initial setup."
"We had some complexities implementing into the other parts of a network."
"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."
"It isn't easy to deploy."
"The price is pretty high and their product stack forces me to use the feature set compared to all the others out there in the market from India."
 

Pricing and Cost Advice

"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."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The price of the solution is expensive."
"We are using the free tier of the solution."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The product's pricing is minimal compared to other products."
"There are no additional costs beyond the standard licensing fees."
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"We can't go without NSX, so it's invaluable from this perspective."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"The solution is free and the price for the support can be expensive."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
"VMware NSX isn't cheap."
"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
