We used to have to bypass on the firewall, proxy, and IPS; now we can do it in one place
For us, it would be great if it supported SSL operations according to Active Directory users. For example, if we want to bypass one of the servers or a client's internet access for SSL interception, we have to do it according to the IP address. It would be better if we could do it according to the Active Directory username. A10 says they kind of support that but we haven't tested it. Another thing is SNI. A10 intercepts all the traffic according to the SNI, the server name indicator. It would be better if it intercepted traffic according to the IP addresses. A10 can only understand that a website is within the banking category or the website is in the social media category, according to the SNI. Without SNI, there is no way to understand it; there is no bypass operation. It would be better if worked without SNI as well. Also, the solution comes with web categories like banking and social media. There are suspicious URLs, malicious URLs, etc. It would be better if it had an application category as well. For example, it would be helpful if we had the chance to bypass all Office 365 applications: OneDrive, Skype, Outlook, etc. According to Microsoft, we need to bypass SSL for all Office 365 applications but we need to create custom categories and put all the Microsoft URLs in them and then we can bypass. It would be great if an application category could recognize Dropbox, for example. For now, we have to put the Dropbox URLs in one custom category and bypass them. Application categories could be very useful.

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) 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.

Quotes from Members

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

Pros

"We have several proxies in our environment, so we localized internet traffic between these proxies. Instead of getting a really huge proxy box, according to our size, we can use three boxes and share the traffic with A10's load-balancer feature."
"With the Thunder SSLi, we're better protected. We can stop use of VPN and proxies. We are better protected against dirty traffic coming back to our schools. Having a secure decrypt zone with the equipment lowers the chances that our security infrastructure could possibly miss an attack."
"Its most valuable feature is its ability to do its job accurately, effectively, and very quickly. The amount of traffic that we have going through our system is astounding... The delay with the SSL decryption turned on is almost unnoticeable."
"The web application firewall feature is the most valuable and useful feature. It is a leading industry product when it comes to load balancing. Its user interface is very simple. There isn't a steep learning curve. When we initiate someone to F5, they start using it quickly."
"I have never faced any stability issues with F5 BIG-IP Local Traffic Manager (LTM)."
"It is a fast and available solution."
"F5 BIG-IP is used with good applications and functions as an application firewall with additional features. We will not use any feature or any service unless there is a business case and there is a need for implementation."
"It is a scalable solution."
"There is a lot of documentation available."
"The most valuable feature of F5 BIG-IP LTM is it helps our delivery team to make policies and rules for application."
"There were a lot of good features. The most beneficial for maintaining server health included the algorithms for the virtual IP, which segment traffic between servers, authentication profiles, and many other things."
 

Cons

"I would like them to have a better UI (better universal design)."
"It would be great if it supported SSL operations according to Active Directory users. For example, if we want to bypass one of the servers or a client's internet access for SSL interception, we have to do it according to the IP address. It would be better if we could do it according to the Active Directory username. A10 says they kind of support that but we haven't tested it."
"There is one thing I would like to see changed. In their features for setting things up, there is a templating system that would normally assist clients. However, we had a better time setting up the device either through the command line or through the interface and not using the templates that were pre-installed. So there is room for improvement to the templates for initial installation."
"The price needs improvement as it is quite costly."
"Bugs are the part of program and they are fixed with every release, as with any vendor."
"I wouldn't recommend the tool to small companies, considering its high price and the infrastructure needs of small businesses."
"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."
"An area for improvement in F5 BIG-IP Local Traffic Manager (LTM) is that it's a high-priced product."
"There is room for improvement in the user interface."
"Needs to provide a visual interface to follow a customer's activity (from client to BIG-IP to SNAT IP to the chosen server, then back). Today, we are still performing packet captures."
"Right now, there are a lot of products within F5's portfolio. They acquired a couple of companies like NGINX and Volterra. Some features and technologies overlapped when this acquisition occurred. They need to refine it and come up with a single, proper solution. F5 should focus more on zero trust network access (ZTNA).They should be more focused on that framework because the industry is moving towards that. Everyone is talking about SASE and zero trust."
 

Pricing and Cost Advice

"We always pay for support. Any organization of our size who doesn't is asking for problems."
"Our licensing costs, yearly, are just under $15,000. Your initial cost of acquisition is obviously going to be more than $15,000..."
"When you purchase the equipment, you purchase the licensing and warranty. It's all fairly standard. We haven't been caught with anything surprising."
"Check other vendors like Cisco, Citrix or A10 Networks. There are plenty in the market with which you can achieve same thing."
"It was probably a one-time purchase and then you have maintenance, but I don't have the details on that. We bought what they called the Best bundle at the time, which pretty much included all of the modules. There was probably no additional cost afterward."
"The tool is a bit expensive."
"Purchasing through the AWS Marketplace was good. We chose to go through the AWS Marketplace because everything that we needed was a soft appliance. We needed something to work in Amazon, and this product was available there."
"Though functionality is high, its cost can be considered slightly higher than its competitors​."
"BIG-IP LTM isn't a cheap solution - I'd rate its pricing as three out of five."
"I am a fan of using AWS natively. It is much cheaper."
"There are a few licensing options available for F5 BIG-IP LTM. You can have a perpetual license which is a lifetime license. You then only need to renew the support, if you choose to open a ticket with the support."
