Leading European web hosting provider IONOS announced that it has selected Sectigo as its exclusive digital certificate authority partner.

IONOS will use Sectigo’s expertise to provide advanced security solutions with digital certificates for its 6 million+ global customers.

Achim Weiss, CEO of IONOS

Achim Weiss, CEO of IONOS, emphasized the importance of the partnership, noting certificates are “the backbone of secure online transactions, particularly for SMEs.”

“Sectigo’s unmatched technical excellence and reliability align perfectly with our mission to empower businesses with superior digital security solutions,” said Achim Weiss.

Under the partnership, IONOS and its 10 international brands — including STRATO, Arsys, Fasthosts, and home.pl — will use a centralized platform for certificate management.

“We are honored to expand our partnership with IONOS, solidifying our position as their trusted Certificate Authority,” said Kevin Weiss, CEO of Sectigo.

The Role of Digital Certificates

The padlock in your browser bar and the “https://” in the URL are the signs of a valid digital certificate at work.

Digital certificates are issued by trusted Certificate Authorities (CAs) and can verify a website’s identity and enable encrypted connections via protocols like HTTPS.

For example:

  • They confirm that a website is actually owned by the entity it claims
  • They help sites comply with regulations such as GDPR and HIPAA
  • They secure communication between the site and its visitors to keep sensitive data safe

Sectigo provides a variety of digital certificates, including SSL/TLS, eIDAS, and S/MIME.

IONOS customers can access these solutions via an API, which will integrate Sectigo’s automated Certificate Lifecycle Management (CLM) platform.

The CLM platform manages certificate detection, issuance, renewal, deployment, and supports multiple trusted CAs.

It’s good timing, too.

Google recently proposed shortening the validity of TLS certificates to 90 days to encourage more frequent renewals and reduce the risk of attackers exploiting compromised certificates.

“This collaboration represents a shared vision for advancing digital trust on a global scale,” said Kevin Weiss. “Together, we are setting a new standard for secure, seamless, and scalable digital solutions.”
