Our firm is moving to a permanent hybrid model, and our traditional VPN is no longer cutting it for security. I’m looking into Zero Trust Architecture to ensure that every access request is verified regardless of where it originates. What are the best first steps for a small IT team to start moving toward a "never trust, always verify" model without breaking our existing user workflows?

Transitioning to Zero Trust is a journey, not a single software installation. The first and most critical step is implementing robust Identity and Access Management (IAM) with Multi-Factor Authentication (MFA). You need to ensure that identity is the new perimeter. After that, focus on micro-segmentation of your network so that even if one device is compromised, the attacker cannot move laterally to sensitive servers. I highly recommend starting with your most critical applications first. Document your data flows and use a "Least Privilege" access policy. It prevents a single compromised credential from becoming a total company-wide catastrophe.
Are you planning to use an existing vendor like Microsoft or Okta for your identity layer, or are you looking for an open-source solution to keep your initial implementation costs lower?
Don't overlook device posture checks. A Zero Trust model should verify that the laptop requesting access is encrypted and has the latest security patches before granting entry.
I agree with Brian. Identity is only half the battle; the health of the endpoint is just as important in a modern hybrid security strategy to prevent malware spread.
Kevin, that is a great question. We actually found that leveraging our existing Microsoft E5 licenses for Conditional Access policies was the most cost-effective way to start. It allowed us to block logins from unauthorized countries and require MFA for all admin roles immediately. The key was doing it in "Report-Only" mode first to see who would have been blocked before we actually flipped the switch. This prevented a massive wave of support calls on the first day of the rollout.
