Ten Vulnerabilities Project, which includes:
SQL injection and cross-site scripting (XSS) attacks.
Broken authentication and session management bugs.
A Modern and Secure Infrastructure

Strict personnel access controls including biometric and PIN-based locks.
Detailed visitor entry logs and video surveillance all day, every day.
Linux servers hardened using industry standard configuration scripts developed by the Center

that your data is safe and secure, even
when the unthinkable happens.
Backups of the database are taken daily,
and sometimes multiple times a day.

the cloud quickly and securely if its data
center is affected by a natural disaster.
