Total Access Control (TAC) from PortSys offers customers a Zero Trust approach to secure access to valuable resources wherever they may reside, local or cloud. This single, scalable solution manages access across the enterprise, offering significantly stronger protection for local and cloud applications, including Office365. TAC brings together multiple security and access technologies, including VPN, SSL/VPN, SSO, Portal, Multi-Factor Authentication, MDM, Application Firewall, Cloud Access Control and more. TAC works hand-in hand with security mechanisms used by cloud providers. Its single sign-on for cloud-based applications, including Office 365, will not lock legitimate users out of their accounts, but still shuts down access for intruders before they can touch your applications in the cloud.
