According to The Open Group:

The O-TTPS, a standard of The Open Group, provides a set of guidelines, recommendations and requirements that help assure against maliciously tainted and counterfeit products throughout commercial off-the-shelf (COTS) information and communication technology (ICT) product lifecycles.

The standard includes best practices throughout all phases of a product’s life cycle: design, sourcing, build, fulfillment, distribution, sustainment, and disposal, thus enhancing the integrity of COTS ICT products and the security of their global supply chains.

This certification program is one of the first of its kind in providing certification for conforming to standards for product integrity coupled with supply chain security.
