Data Center

CallHub uses Amazon Web Services (AWS) as our cloud infrastructure provider. AWS’s world-class data centers are highly secure, nondescript, and have numerous safeguards against perimeter intrusion.


Multi-level physical safeguards

AWS utilizes multi-level biometrics and other physical security safeguards to restrict access to the data centers, as well as regions on the data center floor.

Resilient against system failures

The full redundancy of these data centers in various locations around the world ensures that CallHub will remain resilient in the event of a system failure in one area.

Secure engineering practices in the design and code of CallHub.

Network Firewalls

Each system uses firewalls to restrict access from external networks and between systems internally. To mitigate internal and external risk, access is restricted to only the ports and protocols required for specific business needs.

TLS Encryption

CallHub enforces HTTPS for all services, including our public website. All web session traffic between your application and CallHub is encrypted using TLS (transport layer security) which provides data encryption and authentication between your application and our servers. Sensitive data between applications are also protected by access tokens and are encrypted during transmission.


To prevent unauthorized account access, each session requires an account username and a strong password. All passwords are stored encrypted with a one-way hashing algorithm resistant to brute-force and dictionary attacks by using a salt. Passwords are not logged.

Credit Card

All payments are processed with Stripe. Stripe stores your credit card information on its servers and never reaches our servers. Stripe has been audited by a PCI-certified auditor and is certified to PCI Service Provider Level 1. This is the most stringent level of certification available.

Limited Access

CallHub’s policies and procedures limit and log all external and internal access to customer data and requests management approval before access. Only select CallHub employees dealing directly with valid customer tickets can access customer data with prior permissions.
You also have a choice to use 2FA for account access.

Data Privacy

We take your privacy seriously. Your data is only used/stored in accordance with our privacy policy.


We rapidly & regularly investigate all reported security issues. If you believe you’ve discovered a bug in CallHub’s security, please contact [email protected]. We will respond as quickly as possible to your report.

We request that you do not disclose the issue publicly until it has been addressed by CallHub.
