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 — and an urgent inflection point for financial services organizations.

This shift is more than a compliance mandate. It represents a complete transformation in how organizations must approach certificate lifecycle management (CLM), digital trust, and operational resilience. For financial institutions in an industry defined by customer trust, regulatory scrutiny, and real-time service delivery, the move to 47-day certificates demands an accelerated, automated, and policy-driven approach.

To adapt successfully, financial firms must modernize their security strategies to support the rapid issuance, continuous renewal, and full lifecycle oversight required by this new standard — without introducing unacceptable risk or operational overhead. 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 enhances agility, compliance readiness, and operational continuity
• What strategic and infrastructure changes are needed to future-proof your organization’s trust architecture and risk posture
• The phased rollout timeline for 47-day certificates — and how to prepare your teams, tooling, and budgets for the shift

Download your copy of the whitepaper to gain actionable insights that empower your security, infrastructure, and compliance teams to navigate the 47-day shift — and position your institution as a leader in digital trust.
