Access follows identity, not IP addresses. Open Systems ZTNA gives employees, partners and contractors access to individual applications on a least-privilege, need-to-know basis – agent-based or agentless. Credentials, certificates and MFA layer onto your existing identity provider, while user group, device posture and risk score are validated continuously rather than once at login. SaaS, cloud and on-premises applications are secured alike, with routing through our global points of presence. The service is operated around the clock by Level-3 engineers – no L1 or L2 queues.
