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.

Reliable protection and smooth setup enhance company security

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

"Cloudflare improves performance on my websites and is a great partner for cloud infrastructure for anyone who wants to use the security service and other features."
"From a technical point of view, Cloudflare is the best CDN."
"Another reason it's awesome is that you don't need your server to handle every request."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"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."
"I have used it to bring enterprise-grade features to my small business clients at low or no cost."
"This solution has improved the security of our organization."
"It allows me to see all the traffic on my network."
"We use it to protect our users and their data."
"The product's initial setup phase was really easy."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"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."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Packet inspection has been effective for mitigating DDoS attacks."
"To be able to do the DR and SRM migrations from datacenter to datacenter, we're able to do them with SRM with VXLAN, with the NSX product."
"The initial setup is easy and takes between one and five days."
"The most valuable feature is to control application behavior, and it provides us with features that other products have not."
"VMware NSX is a stable solution; it's very reliable."
"It has allowed our customers to scale extend their existing IP subnets and spin up new subnets on-demand for new app web DB tiers, increasing overall VM-to-VM security and policy deployments and helping increase operational efficiency from a network management perspective."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"If the new user is looking for micro-segmentation in the network space, then VMware NSX is the best solution."
"It works and it is powerful in terms of governance, telemetry, ease of use, and ease of deployment."
 

Cons

"Cloudflare's console should be made more user-friendly."
"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."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"The pricing, setup cost, and licensing for Cloudflare are a bit on the higher side overall."
"Technical support is lacking."
"There should at least be a read-only view of the data so that resellers can properly support the clients."
"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."
"I think they have failed with their technical support."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Earlier versions of firmware had bugs that limit my options."
"The product’s pricing needs improvement."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Alerts and reporting features must be improved."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The web interface could be much better."
"They have some limitations in the firewall features as compared to the on-prem or dedicated hardware appliance. They can add more features, such as IPS and IDS, to the cloud firewall."
"The product need to be improved. It is too complex."
"The price is rather high."
"NSX could better integrate with open-source products. Of course, it integrates with some, but I know many people are uncomfortable deploying NSX with certain open-source solutions, such as Radar."
"The tool's setup is complex and we need support to implement it."
"The solution is only sold as part of a bundle and not as an individual product."
"The solution could improve by having a more streamlined setup."
"The scalability is not perfect."
 

Pricing and Cost Advice

"We are using the free version."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"There are no additional costs beyond the standard licensing fees."
"We don't have any issues with the price."
"The product's pricing is cheap."
"That is one of the great features. I was able to access the majority of the features and services for free."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
"The price of this product is too high."
"If five is a good price and one is a high price, I would rate the price a one out of five."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"The price is pretty high."
"I'm unable to give information on the pricing or licensing cost of VMware NSX because I've never been someone who looks into the economic part of any security or virtualization solutions. That's handled by an entirely different team, and I don't even have the slightest idea about the costs associated with the solution, though I've heard pricing for VMware NSX is on the higher side."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"This solution requires a licence."
"The product pricing ranges from medium to expensive. I rate the pricing a seven out of ten."
