ZeroSSL’s ACME support simplifies the integration of their services into existing automation workflows and infrastructure, making it an attractive choice for organizations that prioritize DevOps practices and infrastructure-as-code principles.

ZeroSSL also addresses another critical aspect of SSL certificate management: certificate transparency. Certificate transparency is an initiative aimed at providing more transparency and accountability in the SSL ecosystem. It involves logging and publicly disclosing SSL certificates in a tamper-proof log, which can be audited by anyone to ensure the authenticity and validity of certificates. ZeroSSL fully embraces the concept of certificate transparency and implements it as part of its service. By logging and making certificates publicly accessible, ZeroSSL contributes to a more trustworthy and accountable SSL ecosystem, mitigating the risks associated with fraudulent or malicious certificates.

When it comes to the technical implementation of SSL certificates, ZeroSSL supports various validation methods. Domain Validated (DV) certificates, the most common type, only require proof of domain ownership. ZeroSSL provides multiple validation options, including email validation, DNS validation, and HTTP-based validation, ensuring that users can choose the most convenient method for their specific needs. These validation methods are designed to verify that the entity requesting the certificate has control over the domain in question, maintaining the integrity of the SSL certificate issuance process.

ZeroSSL also recognizes the importance of maintaining a robust security infrastructure. All certificates issued by ZeroSSL come with 256-bit encryption, ensuring the highest level of security for data transmission. The platform employs industry-standard encryption algorithms and follows best practices to safeguard the confidentiality and integrity of users’ sensitive information. By leveraging strong encryption, ZeroSSL helps prevent unauthorized access to data, protecting users and their customers from potential security breaches.

In addition to the core SSL certificate provisioning service, ZeroSSL provides additional tools and features to enhance the overall security of websites. For instance, ZeroSSL offers a Certificate Revocation List (CRL) service, allowing users to revoke and invalidate certificates when necessary. This ensures that any compromised or outdated certificates are promptly invalidated, preventing their misuse by malicious actors.

Furthermore, ZeroSSL includes support for the Online Certificate Status Protocol (OCSP). OCSP enables real-time verification of the status of SSL certificates, ensuring that they have not been revoked or compromised. By integrating OCSP support, ZeroSSL enables users to validate the status of their certificates on-the-fly, enhancing the overall security and trustworthiness of their websites.
