Discover how global security teams are preparing for the upcoming SSL/TLS certificate lifespan changes, strategize an action plan for your organization, and walk away with a custom toolkit to bring back to your team.

Join Sectigo’s experts and industry peers to:
- Quantify the real-world cost of certificate downtime
- Map hidden lifecycle gaps in your own environment
- Build a 5-step, 47-Day Response Plan you can deploy immediately
- Ensure zero-day visibility, zero-hour outages, and leadership confidence that trust is never at risk.
