emSign Overview
emSign is the globally trusted public Certificate Authority (CA) operated by eMudhra, providing the public trust foundation used within CertiNext for issuing and managing publicly trusted digital certificates. emSign certificates are trusted by major browsers, operating systems, and platforms worldwide, enabling secure communication, authentication, and digital trust for internet-facing services.
As a public trust CA, emSign plays a critical role in enabling HTTPS/TLS, secure email, code signing, and other trust-critical use cases where broad, out-of-the-box trust is required without additional configuration on client systems.
emSign as a Public Trust Anchor
emSign operates a public trust anchor, meaning its root certificates are embedded in leading trust stores used by:
Web browsers
Operating systems
Mobile platforms
Enterprise and consumer devices
Certificates issued under the emSign hierarchy are automatically recognized and trusted by relying parties across the global internet. This makes emSign suitable for external-facing websites, applications, APIs, and services that must be trusted universally.
Within CertiNext, emSign acts as a native public trust option, allowing organizations to manage publicly trusted certificates alongside private PKI certificates through a single platform.
WebTrust-Accredited CA Operations
emSign operates within a WebTrust-audited environment, adhering to globally recognized assurance standards for public Certificate Authorities. WebTrust accreditation provides independent validation that emSign’s operations meet stringent requirements related to:
Certificate issuance and validation practices
Cryptographic key management and protection
Operational security and access controls
Incident management and revocation processes
Compliance with published Certificate Policies (CP) and Certification Practice Statements (CPS)
WebTrust audits are a prerequisite for inclusion in major browser and operating system trust programs and provide assurance that emSign operates in line with industry best practices and regulatory expectations.
Alignment with Global Trust Standards
emSign complies with applicable industry standards and frameworks governing public trust, including:
CA/Browser Forum Baseline Requirements
CA/Browser Forum Extended Validation and Code Signing requirements (where applicable)
X.509 and related PKI standards
AATL (Adobe Accredited Trust List) Requirements for User Certificates
This alignment ensures that certificates issued under emSign are interoperable, secure, and accepted across diverse platforms and ecosystems.
emSign and CertiNext Integration
CertiNext is tightly integrated with emSign, enabling organizations to:
Order and manage publicly trusted certificates from emSign
Automate issuance, renewal, and replacement workflows
Apply consistent policies and approval controls
Monitor certificate health and expiration timelines
Maintain full audit trails across the certificate lifecycle
This integration eliminates the need for separate tools to manage public trust certificates and simplifies operations in environments that use both public and private trust models.
Why emSign Matters
As certificate lifecycles shorten and trust requirements increase, organizations need a reliable, audited public trust provider combined with strong lifecycle automation. emSign provides the trusted root, while CertiNext provides the automation, governance, and visibility required to manage that trust at enterprise scale.
Together, emSign and CertiNext enable organizations to operate secure, compliant, and resilient digital services with confidence in their public trust foundation.
