We received the highest possible rating of 5★ in the registrar certification by the CZ.NIC association. As the only one on the market, we meet the strictest requirements for technical standards, security, and service quality when registering and managing CZ domains.

CZ.NIC registrar certification is the official system for evaluating the quality of services provided by registrars of .cz domains. It assesses technical capabilities, security measures, infrastructure reliability, the level of customer support, and transparency towards clients. Earning five stars means meeting the most demanding criteria — and we are the only registrar to have reached this highest level.

What does it mean for you?

The CZ.NIC five-star rating is not just a formal award. It’s clear proof of qualities that directly affect the security, stability, and administration of your domain and your entire online project.

  • Maximum protection for your domain
    DNSSEC, two-factor authentication, thorough identification, and secure communication significantly reduce the risk of abuse, theft, or unauthorized changes.
  • Full control over settings
    All changes are correctly propagated to the central registry. You have visibility even into hidden data and always know the domain’s current status.
  • Stable operation without outages
    Redundant DNS infrastructure, IPv6 support, and high system availability ensure reliable operation even in critical situations.
  • Confidence you won’t lose your domain
    Automatic expiry alerts, the option of auto-renewal and flexible registration length give your domain long-term security.
  • Transparent pricing with no surprises
    Clear price lists with no hidden conditions, order review before checkout and instant payment processing mean complete pricing certainty.
  • When you need help, you talk to experts
    Support is available 24/7 and is provided by certified domain specialists trained directly by CZ.NIC — not an anonymous call center.
  • Convenient management even at scale
    Bulk operations, a secure API, DNS hosting included, and support for domain auctions save time and support the growth of your projects.
