Compare TLS certificate validation levels
TLS certificate validation levels differ in how identity is verified, how quickly certificates are issued, and the level of trust they provide. Understanding these differences helps you select the appropriate certificate for your environment.
Domain Validation (DV)
DV certificates confirm control over a domain name without verifying organizational identity:
Fast issuance with minimal validation requirements
Focused on encryption rather than identity assurance
Limited verification of the entity behind the domain
Common use cases: internal systems or non-public services, development, staging, or testing environments, and low-risk public sites
Organization Validation (OV)
OV certificates verify the legal existence of an organization in addition to domain control:
Verified business identity
Higher level of trust than DV certificates
Moderate validation effort
Common use cases: public-facing websites, services requiring identity assurance, and environments requiring stronger trust signals than DV
Extended Validation (EV)
EV certificates provide the highest level of identity verification:
Extensive organizational validation
Strong identity assurance
Longer validation timelines
Common use cases: high-trust or high-risk sensitive environments, such as financial services and regulated industries
Validation-level comparison
The following table compares validation levels.
Feature | DV | OV | EV |
|---|---|---|---|
Domain control validation | Yes | Yes | Yes |
Organization identity verification | No | Yes | Yes |
Extended validation | No | No | Yes |
Relative issuance speed | Fastest | Medium | Longest |
Typical trust level | Low | Medium | Highest |
Select a validation level based on the required level of identity assurance, user trust, and operational requirements.
