Corporate Information Security Office (CISO)

The U.S. Postal Service faces ongoing cyberthreats and challenges that directly impact customers, partners, and employees. In support of the Postal Service’s mission to protect its critical stakeholders, the Corporate Information Security Office (CISO) was established to safeguard the USPS network, monitor threats, and respond to incidents.

As with comparable organizations in the government and private-sector, cybersecurity is a top priority for the Postal Service, and an essential enabler to meet the organization’s business goals. Cybersecurity at the Postal Service is every employee and contractor’s responsibility. Even one small cybersecurity event could cause significant operational disruption.
