A certificate for every scenario

From a $18 domain-validated certificate for a personal site to EV identity assurance, unlimited subdomains, IP-only endpoints and SM2 for Chinese compliance — all in one place.

DV Best for starters

Domain Validated (DV) SSL Certificate

Issued in 10 minutes. HTTPS in one click.

Validates domain ownership only, so issuance is fast and inexpensive. A practical fit for blogs, brochure sites, staging environments and small business websites that need HTTPS without paperwork.

How it works

Four steps from order to HTTPS

Every step has a stated turnaround, and a named person follows it through.

01

Pick the right certificate

Tell us your domain count, subdomain structure and compliance needs. We recommend DV, OV, EV, wildcard or multi-domain — whichever fits, without upselling.

02

Validate ownership

DV uses DNS, HTTP file or email verification and usually completes within minutes. OV and EV add business-registry checks handled by our validation team.

03

Receive and install

We deliver the certificate, intermediate bundle and CA chain in the format your server needs — Nginx, Apache, IIS, Tomcat or a cloud load balancer.

04

Monitor and renew

Free reissues for the life of the certificate, multi-channel expiry reminders at 14 and 7 days out, and help with renewal so HTTPS never lapses.

Solutions

Matched to your industry

Compliance rules and domain structures differ by sector. These combinations are ready to deploy.

E-commerce & retail

Protect checkout flows, session cookies and payment pages. OV certificates display your registered company name, which measurably reduces cart abandonment.

  • Wildcard coverage for store and admin subdomains
  • OV or EV for verified merchant identity
  • PCI DSS-friendly TLS 1.2+ configuration

Finance & payments

Banks, lenders and payment processors need the strongest identity assurance and an auditable certificate lifecycle.

  • EV certificates with full entity vetting
  • Certificate inventory and expiry tracking
  • Support for HSM-backed private keys

SaaS & cloud platforms

Multi-tenant products grow subdomains faster than certificates can be reissued. Wildcard and SAN certificates keep pace.

  • Wildcard for per-tenant subdomains
  • Multi-domain SAN up to 100 hostnames
  • Automation-friendly issuance and renewal

Government & compliance

Public-sector projects in China increasingly require SM2 algorithms and MLPS 2.0 alignment alongside international trust.

  • SM2 / SM3 / SM4 national algorithms
  • MLPS 2.0 Level 3 support
  • Dual-certificate RSA fallback

Hosting & IDC providers

Offer certificates as a managed service without building a CA integration. Bulk issuance, delegated validation and white-label support.

  • Bulk issuance and renewal
  • Delegated domain validation
  • API access for provisioning systems

Healthcare & public services

Patient portals and appointment systems carry sensitive data and strict availability expectations.

  • Always-on HTTPS with expiry monitoring
  • OV identity for public trust
  • Deployment help for legacy servers
FAQ

SSL certificate questions, answered

Selection, issuance, deployment and renewal — the questions buyers actually ask.

An SSL/TLS certificate binds a public key to a domain or organization and is signed by a publicly trusted Certificate Authority. Browsers use it to encrypt traffic and to confirm that visitors are talking to the real site rather than an impersonator.
Domain Validated certificates usually issue within 10 minutes to 2 hours. Organization Validated takes 1–3 business days and Extended Validation 3–5, because a human validates company registration, address and operational existence.
DV proves control of the domain and is enough for blogs, staging and internal tools. OV adds verified company details and suits business sites and stores. EV applies the strictest vetting and is used where identity assurance is a requirement, such as banking and payment portals.
Yes. A wildcard certificate covers every first-level subdomain of one name (*.example.com plus example.com). A multi-domain (SAN) certificate covers 3 hostnames by default and can be expanded to 100, across different top-level domains.
Browsers block access with a full-page security warning, so expiry is effectively an outage. We send reminders 14 days before expiry, escalate at 7 days, and can handle renewal and reinstallation for you.
Yes. A certificate is not tied to a single machine. Install the same certificate and private key on every server that terminates TLS for that hostname — including load balancers and CDN edges.
