37signals security overview.

We protect your data.

All data is written to multiple disks instantly, backed up daily, and stored in multiple locations. Files that our customers upload are stored on servers that use modern techniques to remove bottlenecks and points of failure.

Sophisticated physical security.

Our state-of-the-art servers are protected by biometric locks and round-the-clock interior and exterior surveillance monitoring. Only authorized personnel have access to the data center. 24/7/365 onsite staff provides additional protection against unauthorized entry and security breaches.

Regularly-updated infrastructure.

Our software infrastructure is updated regularly with the latest security patches. Our products run on a dedicated network which is locked down with firewalls and carefully monitored. While perfect security is a moving target, we work with security researchers to keep up with the state-of-the-art in web security.

Full redundancy for all major systems.

Our servers — from power supplies to the internet connection to the air purifying systems — operate at full redundancy. Our systems are engineered to stay up even if multiple servers fail.

We protect your billing information.

All credit card transactions are processed using secure encryption—the same level of encryption used by leading banks. Card information is transmitted, stored, and processed securely on a PCI-Compliant network.
