When Backups Walk Out the Door: Why TDE Matters

Details

What happens when a backup drive goes missing? For one regional bank, it meant the potential exposure of sensitive customer data, a full incident response effort, and regulatory scrutiny. This real-world scenario highlights a critical gap in database security—and how Transparent Data Encryption (TDE) in SQL Server can serve as a powerful safeguard.

In this webinar, we’ll break down what TDE really does to protect data at rest, including how it encrypts database files and backups without requiring application code changes. We’ll also explore where TDE fits compared to other options like Always Encrypted and column-level encryption, so you can make informed choices about your security strategy.

Our session will cover:

How TDE works: Key hierarchy, certificates, and key rotation.

Performance considerations: What to expect when enabling encryption.

HA/DR implications: Availability Groups, log shipping, and backup scenarios.

Practical deployment: Checklists, common pitfalls, and lessons learned.

Audit and compliance alignment: Talking points for regulators and security teams.

Key Takeaways:

Understand what TDE does—and doesn’t—protect in SQL Server.

Learn the steps to implement TDE securely with minimal disruption.

Gain clarity on the performance trade-offs and HA/DR impacts.

Walk away with a practical decision framework for when and how to enable TDE.
