Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Ahmed Moamen - PeerSpot reviewer
Protects applications with versatile authentication features
F5 offers a versatile solution that can be integrated with APM in cases where integration with an external IDB is needed. It is useful for authentication backup if the on-prem directory service is unavailable. Additionally, its WAF functionality is valuable for protecting applications from attacks. It is a versatile and strong solution that's easy to understand and deploy.
David Shlingbaum - PeerSpot reviewer
Simple solution and good WAF
Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section. Users get errors or EBAs, and if they want to read about it, they need to find it in the help section of the site. It would be more helpful to allow users to see more information and tips immediately from within the alert.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"The most valuable feature is its usability."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"The solution is very good at mitigating threats."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"New and innovative way to protect the client's data."
"The solution uses AI to protect against botnet attacks."
"The product is used to secure web applications and has the ability to use API templates and bot protection features, such as blocking requests or presenting CAPTCHA pages to end users."
"Web attack signatures are very important for detecting web attacks."
"F5 Advanced WAF offers features not available in other products."
"One of the most valuable features is the Local Traffic Manager."
"I like them because I like the security solution. They get extra marks compared to other solutions or competitors. There are more features than any other product I can think of. They're always monitoring, and the security features offer more than other, lesser products."
"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."
"The AOF solution provides numerous security features."
"The most valuable part is the analytics and visualization."
"Domain name scanning since it allows us to scan all our domain names and determine whether it has malware or if is reported as phishing."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The initial setup was straightforward. Straight forward because the plugin can simply be installed and then it does its job. It's not complex, there is no learning curve. The online scan is simple, you put in the website address and the scan gives us a report on the browser itself. It's simple to use."
"The initial setup was very easy."
 

Cons

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"An integrated SSO feature would be useful for Cloudflare DNS."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"There might be helpful if there was some web application firewall feature."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"Support response time could be improved."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"They could provide better pricing."
"The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic. You only see the top IPs, I think there is more they can offer."
"Support is a little slow."
"The administrator's user interface and some of the settings can sometimes be very complicated to understand."
"I would like to see additional controls."
"The solution could improve by having an independent capture module. It has a built feature that you can deploy the capture on your published website. However, it's not very user-friendly. When you compare this feature to Google Capture or other enterprise captures, they are very simple. It needs a good connection to the F5 Advanced WAF sandbox. When you implement this feature in the data center, you may suffer some complications with connecting to the F5 Advanced WAF sandbox. This should be improved in the future."
"There is a gap in report management."
"The BIG-IQ is supposed to centralize the management for all of the boxes but it's not very effective."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"In terms of improvement, the cost factor is always there."
"The main improvement I would like to see is support for .NET applications. If they could include this feature, I would include more sites in the protection."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"I would rate this solution an eight out of ten. The reason is that we have found sometimes customers or Google saying that there is something wrong with the website but Sucuri says that the site is clean so we do have to look at the site manually which means that the Sucuri scan does not pick up anything and everything."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"I give the price a five out of ten."
"The tool is a premium product, so it is very expensive."
"The price is reasonable."
"A free version of the solution is available."
"The product's pricing is cheap."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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."
"F5 Advanced WAF's pricing is high."
"I rate F5 Advanced WAF's pricing a three out of ten."
"F5 Advanced WAF pricing structure should be adjusted to meet the need of small to medium-sized companies."
"I think the price is very high."
"There are different licenses available to use F5 Advanced WAF, such as BT, ASM, and LPM."
"After buying the program, you just pay for the support every year."
"A yearly license for F5 Advanced WAF is expensive."
"Licensing fees for this solution are paid on a yearly basis."
"The ROI has been very good. Because of the solution, I have a tax break. The site developers were not always experienced people. We used to pay more for cleaning up the site when it was infected. Now, we have peace of mind knowing that the solution will clean up the site and that we won't have to go through the unnecessary process of restoring it from a backup. The protection on the WAF and the measures for backups have also prevented our site from going down."
"I’d simply say it’s really worth it."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
