Code Signing
Sign executables, drivers, and scripts with a certificate trusted by major operating systems.
Code Signing
Digital signing for software and apps, reducing security warnings on download. Since 2023, the private key is protected in a hardware token, as required by the CA/Browser Forum for every code signing certificate.
Code Signing EV
Extended validation of the company, with stricter vetting than standard Code Signing. Hardware-protected key storage is already required for both levels -- the difference is the organization check, not SmartScreen behavior anymore.
Email Certificates
Sign and encrypt email messages end to end.
Personal S/MIME
Digital signing and encryption for emails, proving sender identity and protecting message content.
Frequently asked questions
Which certificate should I choose?
It depends on your use case: DV for fast issuance and simple projects, OV for corporate sites, EV for maximum trust in banks and e-commerce. If you have multiple subdomains, consider a Wildcard; for multiple distinct domains, a Multi-Domain certificate.
What is a Wildcard certificate?
A single certificate that secures the main domain and all its subdomains (*.yourdomain.com), without having to issue a certificate for each subdomain.
How long is the certificate valid?
Since March 2026, the CA/Browser Forum caps TLS certificate validity at 200 days (dropping to 100 days in 2027 and 47 days in 2029). 2 to 5-year plans are a subscription with reissuances included throughout the contracted term, not a single long-lived certificate — and the per-year price drops with longer terms.
How does domain validation (DCV) work?
You prove control of the domain via DNS (TXT/CNAME record), email, or file upload. Our team guides you through every step until issuance.
Do you deliver the certificate already configured on the server?
We deliver the certificate, the trust chain (CA bundle), and the private key ready for installation. Specialized support helps with configuration when needed.
How do I order an SSL certificate?
Ordering is currently quote-based: pick the certificate you want and talk to our team through the contact form. Self-service ordering directly on the site is coming soon.
