Which Certificate Authority?

Navigating Your Certificate Authority Choices

Selecting the perfect Certificate Authority hinges on identifying your specific needs. Are you searching for unbeatable prices, exceptional support, unique features, or unparalleled security? If distinguishing between OV and EV SSL solutions feels daunting, let's delve into key considerations.

SSL Certificate Pricing: Balancing Cost and Value

Price often stands as the primary concern for users, which is understandable. Modern SSL/TLS certificates universally provide 256-bit encryption. Typically, higher-priced options offer additional features, like Extended Validation (EV) SSL certificates, or cater to more complex requirements across numerous sites. However, a steeper price sometimes equates to enhanced security. For many, the most affordable SSL providers hit the mark perfectly.

The Importance of Certificate Authority Reputation

The credibility of SSL certificate providers stems from their recognized authority and trustworthiness in issuing secure SSL certificates. Indeed, the reputation of a Certificate Authority is crucial, especially as cyber threats evolve. Fortunately, when you choose SSLTrust, there's no need to fret over CA reputation. We list only the top SSL certificate providers and leaders in their fields who are ready to meet the needs of businesses, large and small.

What do you need to Secure? How many?

Many CAs offer Wildcard SSL certificates, securing multiple subdomains under single and multi-domain SSL certificates and protecting several domains. Features such as 256-bit encryption, compatibility with major browsers and devices, and warranties to protect against certificate mis-issuance are common. Additional services may include code signing certificates, secure email certificates, and dedicated customer support.

Frequently asked questions

: Certificate Authorities (CAs) play a critical role in internet security by issuing digital certificates that verify the ownership and authenticity of websites and online services. Here's what they do:
Identity Verification: CAs validate the identity of individuals, organisations, or devices requesting a certificate. This process varies in thoroughness, from simple domain validation to rigorous, extended validation, where the CA confirms the legal and operational existence of the entity.
Issuing Digital Certificates: The CA issues a digital certificate to the requester once the verification process is complete. This certificate contains the requester's public key, details about the identity of the owner, the digital signature of the CA, and other relevant information.
Trust Establishment: By serving as a trusted third party, CAs are fundamental in the trust model of the internet. Users and systems can rely on certificates issued by CAs to ensure that the entity they are communicating with is legitimate and that their communications are secure.
Revocation Lists: CAs maintain lists of revoked certificates, known as Certificate Revocation Lists (CRLs), or use the Online Certificate Status Protocol (OCSP) to provide real-time validation status. This ensures that certificates compromised in any way can no longer be trusted.
: The exact number of Certificate Authorities (CAs) can fluctuate due to changes in the industry, such as new CAs being established, existing ones merging, or others ceasing operations. However, several hundred CAs are recognized globally, with varying levels of usage and trust. The most commonly referenced list of trusted CAs is maintained by browser and operating system (OS) vendors in their respective trust stores, such as Mozilla, Apple, and Microsoft.
: Certificate Authorities (CAs) are trusted through technical mechanisms, rigorous validation procedures, and inclusion in trusted lists maintained by software and hardware vendors.
Validation Procedures: CAs undergo strict validation procedures before issuing trusted certificates. This includes proving the security of their infrastructure, the integrity of their issuance processes, and their ability to verify the identities of those to whom they issue certificates.
Inclusion in Trusted Stores: For a CA's certificates to be universally trusted by browsers and operating systems, the CA must be included in their trusted root certificate stores. Vendors of these platforms (such as Mozilla, Microsoft, Apple, and Google) maintain lists of trusted CAs. These vendors independently assess and decide which CAs meet their standards for inclusion.
Audits and Compliance: CAs are subject to regular audits and must comply with industry standards, such as those set by the CA/Browser Forum or local regulatory requirements. Independent third parties conduct these audits and cover aspects of security, issuance policies, and CA practices.
Cross-Signing: A lesser-known but essential method of establishing trust is cross-signing, where an already trusted CA signs a new or less-recognized CA's root certificate. This lends the newer CA immediate trustworthiness, albeit temporarily, as it establishes its own reputation.
Trust in CAs is not static and requires ongoing maintenance. Incidents compromising a CA's integrity, such as issuing certificates improperly, can lead to a CA being removed from trusted lists, effectively revoking its ability to issue trusted certificates in the future.
