Does CPNI produce any standards or recommend security products to use?
CPNI works with a range of stakeholders to develop relevant standards, for example PAS 97: 2009 A Specification for Mail Screening and Security. You can find further details in the protecting your assets section of this website but note that CPNI does not recommend individual products. National infrastructure organisations may obtain guidance from their CPNI advisor; however, CPNI does not provide advice to non-national infrastructure organisations other than what is freely available on this site.
