Our organization is migrating to a hybrid cloud setup, and we want to move away from perimeter-based security. I am looking for practical advice on implementing Zero Trust. How do you handle continuous identity verification without causing significant latency for remote users accessing legacy on-premises applications?

To implement Zero Trust in a hybrid environment, you should start by micro-segmenting your network. Instead of trusting anyone on the VPN, treat every access request as a potential threat. Use an Identity-Aware Proxy (IAP) for your legacy apps; this allows you to verify the user’s identity and device posture before granting access to a specific resource. To reduce latency, deploy edge-based authentication nodes closer to your remote users. This ensure that the "trust but verify" process happens in milliseconds. Also, ensure your IAM policies are dynamic, adjusting access levels based on real-time risk scores like location or time of day.
Have you found that certain Multi-Factor Authentication (MFA) methods, like hardware tokens, significantly reduce the risk of session hijacking compared to SMS-based codes?
We focused on the "Least Privilege" principle. By ensuring users only have access to exactly what they need for their current task, we limited our lateral movement risk significantly.
Nancy is spot on. Least privilege is the cornerstone of Zero Trust. If a single account is compromised, the damage is contained to that one small segment rather than the whole network.
Richard, absolutely. SMS-based MFA is highly vulnerable to SIM swapping. To answer your question: FIDO2-compliant hardware keys are the gold standard because they are resistant to phishing. When we integrated them with our Zero Trust framework, we saw a nearly 90% drop in unauthorized access attempts.
