Networks are only as secure as their weakest link. So, when workers shifted to remote work, cybercriminals quickly moved from attacking the corporate network to targeting often poorly secured home offices. They could then burrow into the network by hijacking encrypted VPN tunnels. Organizations needed a more advanced solution. Secure access service edge (SASE) is an architecture that converges networking and security, combining cloud-delivered security and SD-WAN to ensure consistent and secure access to critical resources for the remote workforce.
