Quotes from Members

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

Pros

"Infoblox is a proactive DNS system that enhances organizational security by blocking and triggering alerts for malicious or suspicious URLs."
"One of the benefits of implementing Infoblox DDI is that it supports both RADIUS and TACACS+."
"The most valuable feature of Infoblox DDI is its IP Address Management (IPAM) tool. This tool allows for the effective management of IP addresses and provides the capability to detect duplicates, hence its moniker "discovery." Another feature that I find particularly useful is the integration of DNS, which can be seamlessly integrated with your existing primary DNS server, making the overall experience much more seamless and efficient."
"Infoblox DDI prioritizes DNS security, which is crucial for the security department."
"Infoblox has more technology patents than any of its competitors."
"It offers an easy initial setup."
"The UI is quite user-friendly and the support is available 24/7."
"The customer service and support are fantastic."
"The most valuable feature of Quad9 is that it is a free solution."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
 

Cons

"In terms of improvement, the commercial pricing could be reduced to attract more small customers. Currently, it is cost-effective mainly for larger enterprises."
"Every vendor or organization cannot purchase Infoblox DDI because of some license issues."
"The pricing model could be more flexible."
"Infoblox encounters some glitches, making it not entirely super stable."
"The solution is expensive."
"The recategorization part takes longer with Infoblox DDI compared to other companies like Symantec, Zscaler, and Palo Alto."
"Currently, it is cost-effective mainly for larger enterprises."
"Regarding an upcoming release of Infoblox DDI, I would like to see an improvement in the existing integration with Ansible. Currently, the integration is not up to par and requires further enhancements, particularly in Ansible version 2.5. Additionally, the GUI is slow, it could be improved."
"It used to work fine for all the devices, but it started to slow and become non-responsive. I would have to reload the page two or three times before all the pages loaded. With OpenDNS, I only need to load the page once."
"Quad9 could improve by having more free features, such as custom DNS filtering."
 

Pricing and Cost Advice

"Infoblox's subscription includes support."
"The license of the solution is expensive, not including the hardware."
"I would say the pricing falls between average and expensive. It's not a cheap product."
