TLP, originally developed to encourage information sharing with and among public and private sector security professionals in the United Kingdom, has achieved widespread adoption around the globe. In regular use by all types of CSIRTs, PSIRTs, operational trust communities, information sharing analysis organizations, government agencies, and private researchers, TLP has achieved "de facto" international standard status. The FIRST community, in consultation with other security information sharing communities, established a Standards SIG for TLP to ensure that interpretations are consistent and that TLP is leveraged appropriately and with clear expectations by all.
The FIRST TLP SIG governs the definition of TLP for the benefit of the worldwide security incident response community and its partners. The TLP SIG members standardize, translate and, as necessary, evolve the TLP in an independent, fair and transparent fashion.
