macmon Secure Defined Perimeter (SDP) Suite is the key for secure access to all company resources whether they are local or in clouds. macmon SDP ensures a Zero Trust Network Access (ZTNA) that is getting more and more important in IT and OT. ZTNA is based on the IT approach of not trusting a device or a user until it is definitively authenticated, to minimalize threat vectors. As our working environment is increasingly reshaped by mobile working, digitalization, the Internet of Things and the outsourcing of various services to clouds, ZTNA must continue to be a key component of integrative IT security solutions in the future. The macmon SDP Suite takes this change into account.
