Security
An overview of Resend security features and practices.
Governance
Resend establishes policies and controls, monitors compliance with those controls, and proves the security and compliance to third-party auditors.
Our policies are based on the following foundational principles:
Least Privilege
Access should be limited to only those with a legitimate business needs, based on the principle of least privilege.
Consistency
Security controls should be applied consistently across all areas of the enterprise.
Defense in Depth
Security controls should be implemented and layered according to the principle of defense-in-depth.
Continuous Improvement
The implementation of controls should be iterative, continuously improving effectiveness and decreasing friction.
Compliance Standards
Data Protection
Data at rest
All datastores are encrypted at rest. Sensitive collections and tables also use row-level encryption.
Data in transit
Resend uses TLS 1.3 or higher everywhere data is transmitted over potentially insecure networks.
Data backup
Resend backs-up all production data using a point-in-time approach. Backups are persisted for 30 days, and are globally replicated for resiliency against regional disasters.
Product Security
Penetration testing
Resend engages with third-party firms to conduct penetration testing at least annually.
All areas of the Resend product and cloud infrastructure are in-scope for these assessments, and source code is fully available to the testers in order to maximize the effectiveness and coverage.
You can download the latest penetration test report on the Documents page.
Vulnerability scanning
Resend uses multiple vulnerability monitoring techniques including code-level scanning, dependency scanning, and security reviews to identify and remediate vulnerabilities.
Vulnerabilities are prioritized based on severity and risk, and are remediated according to the following schedule:
- Critical: 15 Days
- High: 30 Days
- Medium: 90 Day
- Low: 180 Days
- Informational: As needed
Enterprise Security
Endpoint protection
All company devices are equipped with anti-malware protection. Endpoint security alerts are monitored with 24/7/365 coverage. We use MDM software to enforce secure configuration of endpoints, such as disk encryption, screen lock configuration, and software updates.
Security education
Resend provides comprehensive security training to all employees upon onboarding and annually.
Resend’s conducts threat briefings with employees to inform them of important security and safety-related updates that require special attention or action.
Identity and access management
Resend employees are granted access to applications based on their role, and automatically deprovisioned upon termination of their employment. Further access must be approved according to the policies set for each application.
Multi-factor authentication is required for all employees to access company applications.
