Domains & SSL certificates
Your domain is more than just an address on the internet – it is part of your digital identity and therefore critical to your business: it controls websites, email addresses, and key trust signals for your brand. That is precisely why it is worth relying on professionally managed domain services rather than left to operate just “anywhere” as an afterthought.
SerNet handles domain and certificate services in such a way that responsibilities are clear and operations remain reliable.
This is what we stand for:
- Direct domain management as a long-standing DENIC member
- DNS operation with a focus on security to avoid unnecessary downtime and misconfigurations
- Certificates and domain protection measures tailored to your setup and needs
- Clear processes for critical changes instead of off-the-shelf domain management
Request a domain check & setup. In a brief interview, we will clarify which domains are affected, what your goals are (rebuilding, transfer, consolidation), and which components make sense for you.
Domain registration with SerNet
SerNet is a member of DENIC eG and has direct access to the reservation system for domains under .de, the most important German top-level domain (TLD). SerNet also offers reservations for all other top-level domains –from large and widely used TLDs such as .com or .org to small or new TLDs such as .plus, .jetzt, or .forum.
SerNet takes care of the discreet procurement of domains that are blocked by domain grabbers.
For all domains under management, SerNet manages the DNS servers and thus the references for web and mail servers, firewalls, cloud systems, and security and encryption features.
SSL Certificates & Email Protection
Ensure trustworthy communication—with correct signatures, secure certificates, and encrypted web access.
- Choice of Let's Encrypt (free, automated) or Sectigo (validated, manual)
- Professional setup on your servers, including monitoring for ongoing surveillance
- HTTPS redirects with encryption (optional)
- Setup & maintenance of DMARC, DKIM & SPF
- BIMI certificates & logo protection (optional)
Secure operation for domains, DNS, Email and TLS
SerNet understands domain services as providing technically supported operations with oversight. The goal is a consistent setup for DNS, mail authentication, and TLS—with controlled changes for critical processes.
We take care of:
- Registration, transfer, and lifecycle management of your domains
- DNS operation and maintenance of zone entries
- Email security through correct SPF, DKIM, and DMARC
- SSL/TLS as required: Let’s Encrypt or Sectigo, including setup
- Optional: SSL-secured HTTPS forwarding
- Optional: DNSSEC
- Optional: BIMI/VMC Entries and certificates for brand protection
- Process security: dual control principle and additional security for domain deletions/cancellations
