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.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The solution provides good load balancing and protection against DDoS attacks."
"From what I've seen so far, there are no negatives to report as of yet"
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"Easier http to https redirect using page rules"
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"The product helps our organization to access sites located in different regions quickly."
"Compute@Edge features are valuable to me."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product's initial setup phase is straightforward."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Rate limiting is a good feature that protects from volumetric attacks."
"It seems to provide a bit of useful information on website health."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
 

Cons

"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."
"The installation was complex until I learned what I had to learn."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"What I don't like about Fastly is that they charge a heavy price."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"I think Fastly could improve by improving the documentation and having some code examples so that it is easier for developers, since at the beginning it becomes a bit complicated."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"The solution's pricing could be better."
"Support is not that great."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"There are no additional costs beyond the standard licensing fees."
"We don't have any issues with the price."
"A free version of the solution is available."
"I give the price a five out of ten."
"The cost primarily depends on the size of the organization."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"It is an expensive solution."
"The pricing has been very competitive."
"Fastly is less expensive than one of its competitors."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."

"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
