Presidio Bank in San Francisco will offer IronKey Trusted Access to help protect its customers from identity theft, online account takeover and payments fraud.

Trusted Access provides multiple layers of security by integrating cloud-based network services and software that can be downloaded or run from a secure USB device, IronKey said Tuesday.

When a bank begins using the product, it launches a virtualized operating system and Web browser. The browser only works with IronKey's Trusted Network and bank-approved sites.

Trusted Access also allows bank to meet the new Federal Financial Institutions Examinations Council guidance, which all financial institutions must comply with in 2012.
