Core zero trust principles
Explicitly verify every access (user, device, workload). Least privilege. Assume breach — segmentation limits lateral movement impact.
Zero trust complements perimeter firewalls — especially as hybrid cloud and remote work expand the attack surface.
Common technical components
Identity: MFA, conditional access, PAM for admins. Device: compliance checks before access. Network: micro-segmentation, ZTNA/SASE instead of flat VPN.
Data: classification, encryption, selective DLP. Visibility: centralized logging and anomaly detection.
Phased implementation roadmap
Phase 1: asset/identity inventory, admin MFA, critical VLAN segmentation. Phase 2: ZTNA for key apps, backup hardening. Phase 3: policy automation and SIEM/SOC integration.
Intilogy supports maturity assessment, segmentation design with Fortinet/Sophos, and integration with existing infrastructure.
Frequently asked questions
Is zero trust only for large enterprises?
No. SMBs with cloud and remote staff benefit — start with MFA, segmentation, and ZTNA for critical applications.
