The CA/B Forum’s decision to reduce the lifespan of public TLS certificates to just 47 days marks a pivotal moment in digital security. This shift is more than a compliance mandate—it represents a complete transformation in how organizations must approach certificate management and digital trust.

To adapt successfully, organizations must evolve their security strategies to support the rapid issuance, renewal, and oversight demanded by the new 47-day TLS certificate standard.

This in-depth whitepaper, authored by security pioneer Ryan Hurst, explores the implications of the new 47-day certificate lifespan and what it means for your business.

Inside, you'll learn:

• Why shorter TLS certificate lifetimes are critical to limiting risk and minimizing the impact of key compromise
• How automated certificate management and continuous renewal increase agility and resilience
• What strategic changes are needed to future-proof your infrastructure against emerging threats
• The phased rollout timeline for 47-day TLS certificates—and how to prepare your team and tooling

Download your copy of the whitepaper to gain actionable insights that empower your organization to transition smoothly and lead in a rapidly evolving security landscape.
