The tech stack reveals infrastructure-first positioning—Aruba, HPE, Fortinet, Palo Alto, Azure—paired with security-heavy hiring (15 open security roles vs. 21 engineering) and active adoption of SASE. Projects cluster around cloud security hardening, zero-trust implementation, and hybrid-system design for regulated customers, suggesting a shift from on-prem infrastructure consulting toward cloud-native security architecture.
