1. What is ServiceNow Cloud Encryption and why is it important?

• It protects customer data stored in the ServiceNow cloud using strong encryption standards like AES‑256.

• All data at rest, including tables, logs, and files, is encrypted by default.

• It’s essential for meeting regulatory standards like GDPR, HIPAA, and FedRAMP.

• It ensures data remains secure even if platform access controls are compromised.

• It supports both ServiceNow-managed keys and customer-managed keys (BYOK).

• Encryption builds customer trust and enables secure digital transformation.

2. What’s the difference between ServiceNow’s default encryption and BYOK?

• Default encryption is managed by ServiceNow and applied to all customer data at rest.

• BYOK (Bring Your Own Key) gives customers control over their encryption keys.

• With BYOK, customers can rotate, revoke, or audit key usage directly.

• BYOK helps meet stricter compliance requirements in regulated industries.

• It adds more transparency and control for customers with high security needs.

• The choice depends on your risk appetite and regulatory landscape.

3. Why would an enterprise choose BYOK over default encryption?

• To maintain full ownership and lifecycle control of encryption keys.

• To align with internal security policies or industry compliance mandates.

• To enforce geo-specific key storage or usage restrictions.

• To add an extra layer of governance and auditability over sensitive data.

• Because certain regulators require proof of key control during audits.

• It’s about reducing third-party dependency on data security.

4. What is encrypted by default in ServiceNow’s cloud architecture?

• All customer data stored in tables, including attachments and field values.

• System files like undo/redo logs and binary logs are also encrypted.

• Clone, backup, and replication data is protected automatically.

• All new and existing production instances are covered by encryption at rest.

• Activity logs and operational metadata are encrypted too.

• There’s no need for customers to configure this—it’s automatic.

5. Does Cloud Encryption impact instance performance?

• No, it’s optimized to run in the background without affecting performance.

• Encryption uses hardware acceleration via trusted security modules.

• The platform is designed to scale with encryption enabled by default.

• All encryption tasks are transparent to the end user or developer.

• It’s part of the infrastructure layer and doesn’t touch app logic.

• ServiceNow has tested it extensively to ensure zero service disruption.
