"Great Option to Limit Advertising and Unwanted Websites"
5/5
What do you like best about CIRA DNS Firewall?

The firewall is easy to configure and has an option to temporarily disable in order to test sites. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

Using the advertising block feature can mean email links do not work. You then have to figure out what the link is and add it as an allowed site. Minor in the overall scheme of things. Review collected by and hosted on G2.com.

"Outstanding value"
5/5
What do you like best about CIRA DNS Firewall?

It adds another layer of content and security control. Redundancy alone would be worth the price, but it also augments our other security tools. It is super simple to setup. Policies can be broad or granular as you needed. It catches malware payloads that have not yet been detected by other vendors.

I love tools that are simple, effective, and affordable. CIRA's D-Zone Firewall checks all 3 boxes. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

I do not dislike anything. It seems like I need to add more letters to meet some kind of minimum. Review collected by and hosted on G2.com.

5/5
What do you like best about CIRA DNS Firewall?

It's super easy to setup and manage. and it's nice peace of mind knowing that there is an additional scan happening above our corporate firewalls

Thanks for adding the HTTPS blocks in the reporting. Our counts went way up after that was added. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

reporting aspects good be better, but what is there now works ok.

Would be great to see the IP associated with the blocks/alerts

There are some false hits, like at one point 'reddit.com', but we can manually whitelist them Review collected by and hosted on G2.com.

"Great value for an effective and simple security solution"
5/5
What do you like best about CIRA DNS Firewall?

Simple set up and good security with no false positives so far. No need for any on prem systems and very quick to get it going. No real administration is required once it's set up. The daily reports include a csv so that you don't miss any activity that happens while away for the weekend for instance. The price is great particularly for cash strapped startups. The people at CIRA are very flexible on terms and provide excellent support and training. Multiple profiles available, content filtering. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

No reporting (with the exception of daily reports) or view of history. A report of blocks for a period whether it's a week or a month would help to show management what's happening within the organization and that we're getting value for this service. Even if it was just a csv. Review collected by and hosted on G2.com.

"CIRA DNS Firewall is worth the small investment"
5/5
What do you like best about CIRA DNS Firewall?

It is straightforward to set up and manage. We use it as another security layer. A few times a month, it catches something our other systems missed. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

I think it needs better advertising and more exposure. Very few people I speak with have ever heard of it. Review collected by and hosted on G2.com.

"An elegant extension of your current security implementation"
5/5
What do you like best about CIRA DNS Firewall?

The product is so easy to implement, and manage. Zero maintenance required. Very low number of false positives. Ability to customize profiles for various networks that we manage. We can create filtering profiles for students and faculty that are less restrictive than we might have for administrative staff. Global protection across all of our campus ensuring that all systems are protected against malware and phishing. Other products like the DNS filtering that can be implemented on our firewall break on SSL connections causing certificate errors without installing a certificate on the client machines. This solution works very well in a BYOD environment where it becomes more difficult to trust vendor certificates globally. DNS Firewall Instantly blocks access from infected systems to their C2 servers. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

I would love to see a tool set developed to correlate blocks against logged DNS queries on our Windows and BIND DNS servers. Quick start guides should include documentation for forwarding BIND servers to CIRA D-Zone DNS Firewall servers. We would really appreciate a self-service URL for end users to submit what they consider to be false positives. Perhaps this could be done via a button on the block page. I would also like a bit more information displayed on the block page such as the URL and IP that were blocked although I understand that this could be challenging due to the nature of the product, and being that the client hitting the blocked page is different from the server doing the recursive lookup.

"Excellent Tool"
4/5
What do you like best about CIRA DNS Firewall?

Easy to use interface, cost effective and robust detection. Makes it easy to automatically add a blocking control that's based on a threat feed and also manually block sites that may be reported as malicious. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

I found the interface a little confusing at first. Once I got the hang of it it was easy, but I wish there were faster ways to do common tasks like manually block a site. Review collected by and hosted on G2.com.

"Best service ever!!"
5/5
What do you like best about CIRA DNS Firewall?

The network I manage has over 1200 endpoints. Primarily k12 teachers, students and public libraries. This service has identified 10's of thousands of bots and malicious websites that would have gone unnoticed by the sector. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

If a school division is using an additional layer of content filtering, it is also a cloud service and it also requires DNS forwarding so the D-Zone service cannot be used as well. Review collected by and hosted on G2.com.
