Proactively secures DNS by blocking malicious URLs and triggers necessary alerts
I work with Infoblox DDI for DNS management, which involves blocking malicious and suspicious URLs. This helps in protecting my organization's domain name system and involves deep investigation and policy enforcement to understand why certain URLs are being used Infoblox is a proactive DNS system…

It's easy to use and set up, but I've faced performance problems
I have experience with Quad9 and most other filtering solutions. Quad9 was working well initially, but it started slowing, so I switched to OpenDNS. I recently checked Tom's Hardware, an IT review site, and read a review of seven DNS filters. Open DNS was ranked the fastest, and Quad9 was second. Google was on there too, but they said it didn't filter enough.

Quotes from Members

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

Pros

"It offers an easy initial setup."
"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 is a proactive DNS system that enhances organizational security by blocking and triggering alerts for malicious or suspicious URLs."
"Infoblox DDI is a good tool if you want to centralize everything in your environment...It is a stable solution."
"The customer service and support are fantastic."
"Infoblox DDI is capable of fulfilling customer requirements from a DNS security, DHCP, and IPAM perspective."
"Infoblox has more technology patents than any of its competitors."
"The UI is quite user-friendly and the support is available 24/7."
"Setting up Quad9 is straightforward if you know what you're doing, and it's easy to use overall."
"The most valuable feature of Quad9 is that it is a free solution."
 

Cons

"It would be helpful if we can log in and click on the server, and have the CLI pop up directly instead of using third-party software, like PuTTY, to log in."
"Currently, it is cost-effective mainly for larger enterprises."
"The pricing is quite expensive, which is why I recommend it for medium and large enterprises and not for small businesses."
"Every vendor or organization cannot purchase Infoblox DDI because of some license issues."
"There are some bugs and glitches that need attention."
"The pricing model could be more flexible."
"Infoblox DDI could be slightly improved in terms of scalability."
"The recategorization part takes longer with Infoblox DDI compared to other companies like Symantec, Zscaler, and Palo Alto."
"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."
"Infoblox DDI is an expensive product."
"The price of Quad9 is free."
