"The report shows 92% of survey respondents recognize the importance of adopting a zero trust architecture; however, it is concerning to see many organizations are still using a VPN for remote employee and third-party access, inadvertently providing a juicy attack surface for threat actors," said Deepen Desai, Global CISO and Head of Security Research, Zscaler. "Legacy firewall and VPN vendors are spinning virtual VPNs in the cloud and claiming that it is zero trust, and they go the extra length to hide the word"VPN". Customers need to ask the right questions to make sure that they are not getting a false sense of security with these virtualized legacy offerings in the cloud. In order to safeguard against evolving ransomware attacks, it is critical for organizations to eliminate the use of VPNs, prioritize user-to-app segmentation, and implement an in-line contextual data loss prevention engine with full TLS inspection," added Desai.
