Short-Lived Certificates

Introduction

The industry is increasingly moving toward the use of short-lived certificates as a best practice for enhanced security. This shift is being led by the CA/Browser (CAB) Forum, which has already reduced certificate lifespans from 398 days to 200 days—and is now discussing even shorter validity periods, such as 47 days.

To keep up with these changes and maintain secure operations, organizations are encouraged to implement automated certificate management. Automation helps ensure continuous trust without the need for frequent manual updates, reducing the risk of expired certificates and improving overall security posture.

AppViewX, with its existing automated Certificate Lifecycle Management (CLM) framework, empowers customers to extend automation to short-lived certificates seamlessly.

As the industry accelerates toward shorter certificate validity periods, AppViewX ensures enterprises are prepared with an automation-first approach. By combining short-lived certificate issuance, automated DCV, pre-canned ACME clients, certificate archival, and enhanced onboarding, AppViewX delivers a future-ready CLM platform that reduces risk, improves agility, and ensures continuous compliance.

With AppViewX, customers can confidently scale to 90-day, 45-day, or even shorter-lived certificates, while keeping certificate operations simple, secure, and automated.

Benefits of Short-Lived Certificates

  • Seamless Transition to Short-Lived Certificates: Extend existing CLM processes without re-architecting workflows.
  • Faster Adoption with Pre-Canned ACME: Reduce onboarding friction for developers and admins by using preconfigured ACME clients.
  • Improved Domain Readiness: Automated DCV ensures domains are always validated and ready for certificate issuance.
  • Stronger Security Posture: Short-lived certificates reduce the attack window for compromised keys and minimize CRL/OCSP reliance.
  • Policy-Driven Automation: Certificates and domains follow centrally defined validity and validation policies.
  • Operational Efficiency: Archival, automated onboarding, and delegated management reduce manual effort at scale.
  • Role-Centric Control Device admins gain autonomy to manage their own certificates within controlled boundaries.

Prerequisites

  • Devices are onboarded into AppViewX.
  • CA accounts (public and private) are integrated.
  • Role-based access control and delegation are configured.
  • Auto-enrollment and auto-regeneration are enabled.
  • CI/CD pipelines and API integrations are in place.
  • Automated CLM processes are operationalized.

New Capabilities

  1. Define Lower Validity for Renewed Certificates

    Administrators can set shorter validity periods (e.g., 30, 45, or 90 days) for certificates at the time of renewal.

    Certificates no longer default to their maximum validity; validity is policy-driven and configurable.

  2. Monitor Validity Configurations

    Tracks configured validity periods against both organizational policies and CAB Forum recommendations.

    Alerts and reports highlight certificates that deviate from approved validity standards.

Existing Capabilities Extended to Short-Lived Certificates

  1. Configurable Certificate Enrollment Validity

    Define validity during certificate enrollment through CA Policies. See Enrolling Certificates from Policy Engine

  2. Configurable Certificate Renewal Validity

    Define validity for renewed certificates, now extended to short-lived certificates. See Updating Renewal Validity.

  3. Validity Control in Enrollment Protocols

    Enrollment enforces policy-aligned validity controls.

    Enables short-lived issuance without workflow changes.

Platform Enhancements

  1. Automated Device Onboarding

    Devices discovered via network scans can be auto-onboarded with minimal manual effort.

  2. Delegated Device Onboarding

    Device onboarding policies allow administrators to delegate onboarding to application or device owners.

  3. Device Administrator Persona

    Introduces a dedicated persona for device admins to manage certificates for their own endpoints.

  4. Precanned ACME Clients
    • Provides ready-to-use ACME clients packaged with AppViewX tenant/environment details. See Configuring AppViewX ACME Client.
    • Users simply download for Linux or Windows and begin using without configuration overhead.
    • Ensures faster rollout of short-lived cert automation with consistent and error-free setup.
  5. Automated DCV Management (See DCV Management)
    • Automatically discovers validated domains from the CA.
    • Continuously monitors domain validation expiry and enables auto-renewal.
    • Sends proactive notifications to prevent DCV lapses.
    • Allows admins to onboard new domains directly into the CA through AppViewX.
  6. Certificate Archival
    • Automatic archival of expired, revoked, or renewed certificates.
    • Keeps the certificate inventory clean and focused on active certificates.
    • Archived certificates remain accessible for audits and compliance checks.
    • Ensures admins focus on the certificates that matter most.
