The NESAS scheme is a collaboration and jointly led by 3GPP and the GSMA, and is open to all vendors of network equipment products that support 3GPP defined functions. NESAS has been developed to strengthen the level of security in 5G and LTE networks following established best practices and schemes that provide security assurance.

atsec is an GSMA appointed laboratory to provide Network Equipment Security Assurance Scheme (NESAS) security audits and network product evaluations against NESAS Security Assurance Specifications (SCAS).

In the course of the NESAS audit, we provide documentation review of vendor development and product life-cycle processes and conduct interviews to assess compliance to the specified security requirements. The list of mobile network equipment vendors that have undergone an assessment and independent audit of their development and product life-cycle processes is available on GSMA’s website, which you can find here.

In the course of the network product evaluation, we apply test specifications from the relevant SCASes and run detailed tests on the network product. Test results are recorded in an Evaluation Report and provided to GSMA, if the evaluated product is to be listed on the NESAS website.
