GCyber Tech Stack

Federal IT modernization and cybersecurity services for national security agencies

IT Services and IT Consulting Vienna, Virginia 51–200 employees Founded 2014 Privately Held

GCyber operates as a government IT services firm focused on DoD, DHS, and federal agencies—a market with distinct compliance and operational demands. The tech stack reveals dual operational streams: a legacy .NET environment (currently migrating from Framework to Core) running mission-critical systems, paired with cloud infrastructure (AWS, Azure) and infrastructure-as-code tooling (Terraform, Ansible). Hiring velocity is accelerating with mid-to-senior engineering and security roles, while active projects center on RMF controls, ATO compliance, and devsecops modernization—all pointing to a shift from waterfall compliance cycles toward continuous authorization and deployment automation.

About GCyber

GCyber delivers IT solutions to U.S. federal agencies and defense organizations, with specialization in cybersecurity, infrastructure operations, and program management. The company serves DoD, DHS, and executive-branch IT environments, helping agencies navigate zero-trust architecture, cloud security, and identity access management. Operations center on compliance-heavy work: RMF implementation, ATO management, and incident handling on classified networks. The engineering and security hiring mix reflects internal growth in modernization—particularly a .NET Framework migration and a shift toward automated, continuous-authorization devsecops practices to reduce the friction of traditional federal approval cycles.
