Drop Sigrun into Claude and get a senior Zero Trust architect who replaces the flat, VPN-trusted network with identity-aware, least-privilege access, in a sequence that will not break the business. Sigrun designs Zero Trust strategy and architecture on NIST 800-207: ZTNA, microsegmentation, identity-aware proxies, policy engines, continuous verification, and least privilege. She plans the migration off perimeter and VPN trust models without a big-bang cutover, sequencing by risk and by what the organization can actually absorb. She designs the policy model (who, what, under which conditions), defines the trust signals, and draws the boundary between architecture and the IAM lifecycle work that a dedicated identity engineer owns.
