How are clients satisfied with our products

About FRED

A good CZ.NIC reputation in the field of software development and many advantages of FRED has led us to choose FRED software for running our .ar domain registry among other options. The first installation of FRED and data migration took us only 3 months. We especially appreciate the stability and accuracy of the software and a very good level of support. Another FRED advantage is its modularity and many available features – we are also considering using the registry lock, duplicate contact merger or automated keyset management.

About Knot DNS

"DENIC eG has been using Knot DNS since January 2019. The Zone Signing team chose Knot DNS because it provides modern key management features and excellent design for container usage. Additionally, it's a product with a broad user community, and the feedback of RIPE for the usage as a signing software was pretty good. On the other hand, the DNS Operations team was searching for an additional authoritative high performance nameserver for selected nameserver locations serving the .de zone. Knot DNS met their expectations. All in all, DENIC is completely satisfied with Knot DNS because the software is easy to use, with highest performance and stability."

"Knot DNS is powerful yet easy to configure authoritative DNS server. The DNSSEC signing engine built in is second to none when comparing features and performance. Best of all, the support behind Knot DNS is excellent."

We have been using Knot DNS server for approximately five years – since 2017. The primary purpose of its choice was to support the automatic DNSSEC signing and dynamic synthesis of records. Knot DNS significantly reduces the complexity of zone signing and key rollover. In addition, it is an open source software. The quality of this software is very good, it is rock-stable and prebuilt binary packages for main Linux distributions are very appreciated. Definitelly it improves the overall stability and robustness of our DNS. We can also recommend CZ.NIC as a bussines partner.

We are also very happy with its simple YAML-based configuration, operational ease-of-use, and service management tools. Both Knot DNS and BIRD are strong software products from CZ.NIC."

About ADAM

"DENIC is using dns-probe of the ADAM toolstack for processing packet files out of DNS data. This is necessary for a running Big Data project. Besides Knot DNS, working with CZ.NIC is very productive and straight forward also regarding ADAM. Every issue DENIC and CZ.NIC investigated together was processed professionally and fixed very quickly. Communication has always been direct, fast and friendly, and we appreciate that very much."
