What do you like best about CIRA DNS Firewall?

D-Zone was very easy to implement. I routed all of our division's dns requests to D-Zone. Then went and tweaked the settings based on the IP address that the request was exiting on, and then just watched it work. I really like the weekly email reports just to keep tabs on the service. I breathe a sigh of relief every time I see the number of Malware and Phishing attempts that were blocked. I loved it so much, that I immediately set it up at my home when it became available.

The interface in the beginning was a bit difficult to understand. Having said that though, over the years it just keeps getting better. Review collected by and hosted on G2.com.

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

As part of our multi layer approach to security, CIRA DNS was an easy fit to provide an additional layer of security at the DNS layer for the entire organization. We like that it is cloud based, easy to setup and seamless for our end users. The interface is easy to use. Once setup, you rarely need to do anything. Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

If I had to pick something it would be the addition of more granular reporting (ex. include IP info). Review collected by and hosted on G2.com.

"Great way to start protecting the users"
4.5/5
What do you like best about CIRA DNS Firewall?

- Easy to implement / easy to manage

- In our case, it offers a good "first level" of protection (or could be added to an existing solution depending on the case)

- Very little overhead; once the configurations are done, you basically have nothing to do.

- Simple, yet effective

- No hardware required

- No upgrades or updates required

- CIRA team is easy to work with Review collected by and hosted on G2.com.

What do you dislike about CIRA DNS Firewall?

There isn't much to dislike about the platform; maybe it would be nice to have access to some more reports but it's not a "dislike", would be more like a "nice to have" Review collected by and hosted on G2.com.
