Bonieber  Orofeo - PeerSpot reviewer
Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.
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.

Quotes from Members

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

Pros

"The capability is at a seven or eight out of ten."
"Initial setup is easy and pretty standard."
"We are fond of the load balancing feature for DNS and servers."
"The scalability of the solution depends on the sizing of the network. Generally, the scalability is quite good."
"Along with load balancing, we perform a lot of packet inspections, URL rewriting, and SSL interceptions via iRule."
"The main reason that we suggest this product to our clients is the great integration with other security tools, such as IBM Guardium."
"The F5 interface is easy to use."
"We enjoy its overall ease of use."
"High availability, performance, and security are the main pillars. It enhances the security for accessing the applications."
"Provides resiliency for applications that reside on servers, as well as connectivity to remote applications."
"My customers have told me that the performance of this solution is good."
"It's very easy to configure."
"We use the product for load balancing and as a reverse proxy solution."
"What I like most about Citrix NetScaler is its stability, and I didn't see a lot of issues with it."
"The web application firewall is one feature I found valuable in the solution."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
 

Cons

"The synchronization does works fairly well. However, if I were to make changes, I would make it easier to start the sync process."
"The license terms for "non-commercial" will be a challenge for us."
"Reporting could be improved and configuration made easier."
"Its GUI could be a bit better. Other than that, it's already pretty good. We don't use it in a high-performance environment. So, we don't really care so much about too many features."
"The deployment can take some time because you can do a lot of configuring to meet the needs of the use cases for clients."
"The auto logout feature after three minutes is terrible. I wish they would make that longer, since it is not a feature that we can change."
"In terms of native integrations, there is a lot of instability. Also, integration is not robust with F5."
"The license terms for "non-commercial" will are challenging for us."
"I feel that Citrix NetScaler's customer support needs to improve."
"An area for improvement would be the difficulty in finding information about standard licensing costs over the internet. They should provide some reference prices on the net to be quickly referred to."
"Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us."
"The product provides some templates to integrate with applications like MS Exchange, MS SharePoint, SAP Enterprise Portal, and others. However, the last update for these templates was 2013 (lots of applications are running on versions newer then 2013)."
"The solution is a bit more expensive than some of the available solutions in this region. One solution in particular that I noticed was cheaper was Kemp."
"We face challenges with the solution's firmware upgrades frequently."
"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."
"I would like to see support for scripting, like "iRule", which gives you the option to implement any configuration which is not available out of the box."
 

Pricing and Cost Advice

"Try to negotiate all the software features that you require upfront."
"Unless the price difference is large, this is not the primary concern for the product. The performance and product-related issues (secure for VPN, multi-function for network device, etc.) are the keys."
"F5 BIG-IP can be expensive, although there are trial versions available which are helpful to find out if the solution is right for your company."
"It is a bit expensive product. Kemp Loadmaster is much cheaper than F5. Its licensing is on a yearly basis. It can be for one year or three years."
"The price is little bit on higher side compared to the cost of NGINX."
"The price of F5 BIG-IP Local Traffic Manager (LTM) is too high."
"It is sort of a commodity product. A load balancer is a load balancer. What will be, at the end of the day, the cheapest option or have the best performance, that is what it will come down to."
"LTM is a good product, but it's expensive. They should make it more competitive because cloud providers offer free load balancing. Cloud providers can't cover all the security aspects of F5, but you get a decent amount of security. Cloud environments are becoming the norm across the IT industry. Many of the larger companies that previously used on-prem infrastructure are switching to the cloud, so companies like Fortinet and Palo Alto are reducing their prices. Otherwise, they can't compete in the cloud."
"The pricing for Citrix Web App and API Protection is unreasonable. I don't know the exact price, but I heard it's tens of thousands and it's a bit too much for the small country I live in."
"The price for Citrix ADC here in Mexico was good, when you compare it with F5 and Radware."
"Citrix ADC could improve the price and make it less expensive, other competitors have a better prices. This would allow Citrix ADC to keep dominating the market."
"NetScaler does the same thing as an F5 and it's cheaper."
"It is an enterprise solution. Thus, its costs are reasonable."
"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."
"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."
"I give the price of the solution a seven out of ten."
