The article explains that ZTNA improves access security over traditional VPNs by granting session-based, least-privilege access, but warns that ZTNA alone is insufficient because compromised credentials, malicious insiders, or infected devices can still cause breaches. It recommends combining ZTNA with device posture checks and additional security controls (NGFW, IPS, CASB) and deploying these capabilities as part of a SASE platform to balance security and performance.
