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.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.
Shashank N - PeerSpot reviewer
Provides good stability, but the agent-based approach could be more convenient
The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF. Additionally, the agent-based approach presents challenges with managing agents across versions and dependencies on specific application platforms like Apache or NGINX, leading to compatibility issues and complexity in integration. This agent-based system proved particularly difficult to manage.

Quotes from Members

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

Pros

"The solution automatically detects and responds to certain types of traffic based on geolocation."
"It is a fast and secure DNS."
"Easier http to https redirect using page rules"
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The UI is good."
"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."
"Helped us a lot with load balancing."
"We have good customer support."
"The load balancing feature and the fact that you can do context switching in the WAF are the most valuable. We majorly use it for load balancing, but we also use it for context switching in the WAF. It is also robust and very easy to work with and manage."
"The most valuable feature for us is the application firewalling in Citrix NetScaler, ensuring only valid traffic enters our environment."
"The load balancing and VPN features are most valuable. AAA authentication is also valuable."
"Citrix Web App API Protection allows you to enable a blocking mode"
"One feature that works really well is the SSL VPN. It's very easy to set up and you can go very granular with it. You can define what user groups get what kind of access and the management overhead is very low."
"I found that the GUI was very easy to to navigate. If you were looking for something, it was fairly easy to find. There's a lot of third-party documentation and information available online as well."
"The product's most valuable feature is its ability to set up the rules easily."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
 

Cons

"The analytics, basically the dashboard, doesn't have much to it."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"There should be a specific price list for enterprise-level customers."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"Integration involving API with other products could be more user-friendly."
"Technical support is lacking."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"Overall the price of Citrix ADC could be more competitive."
"Too many bugs in the software and it's always difficult when you need to update."
"The WAF component needs to be simplified so that it is easier to use."
"The configuration is complex, and only one or two people know how to assist when problems arise."
"The technical support could be improved. They do not respond or assist customers in a timely manner."
"It can be difficult to setup."
"Citrix ADC can be really complex. It isn't very simple like some other appliances that I've worked with. You need a lot of skill and experience to manage it. I'm not talking about a year or two. You need at least four years to understand it very well. It is not that easy to learn. They should make it a lot simpler for users to understand the management of it. They can also provide some additional training. The material they have on the site is not sufficient enough for you to understand how to manage it. Their training is expensive, and not everyone has the funds and experience for it. Citrix isn't very popular around these parts of the world. So, it can use some more marketing, sales, enlightenment, and advertisement. These could bring more market for them. Basically, there are just a few companies that really go for Citrix. Most of the companies go for VMware because they marketed themselves more than Citrix. There isn't much difference between Citrix and VMware. VMware is a little more robust than Citrix. Citrix has focused more on desktops rather than server virtualization, and that's the advantage VMware has over Citrix. Citrix also needs to educate and inform users about the infrastructure that is supported with a version. Currently, if the customers don't look at the datasheet, they might miss this important information."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
 

Pricing and Cost Advice

"The tool is a premium product, so it is very expensive."
"I give the price a five out of ten."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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."
"We are using the free tier of the solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"It all depends on the features that will be used and the number of accesses."
"The pricing could be lower."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing an eight or nine out of ten."
"I rate the pricing an eight out of ten since it is expensive."
"There isn't much of a difference between the cost of Citrix and that of other similar solutions."
"For partners, NetScaler is not as expensive price-wise versus F5."
"Ninety day free trial makes it easy to try out this solution."
"You get the value for your money. There aren't any hidden fees."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
