Fieldwire, acquired by Hilti in 2021 for over $300 million, operates a field management platform deployed across more than four million construction projects worldwide. The attack surface is interesting: a device-agnostic system - web, iOS, Android - deliberately engineered with offline capabilities for jobsite environments where connectivity is unreliable or nonexistent. That means sensitive project data, team communications, and performance tracking persist locally on devices scattered across commercial, industrial, heavy-civil, and residential sites globally.
The platform connects everyone from foremen to project managers in a single interface, handling coordination and risk reduction across construction verticals. From a security standpoint, the threat model centers on protecting data at rest on field devices, managing sync conflicts when connectivity resumes, and securing the integration points between mobile clients and cloud infrastructure. Offices span San Francisco, Paris, Australia, and Japan, with the Hilti acquisition enabling accelerated scaling of the platform internationally.
Technical domains relevant to the security team include mobile application security across iOS and Android, offline-first data architecture, and construction technology where the stakes involve protecting proprietary project data on active jobsites. The engineering challenge is maintaining integrity and confidentiality across a platform built to function regardless of network conditions - a design choice that trades centralized control for field reliability, which means the security model has to account for both states.
