About Digitriva
Digitriva was founded in Munich in February 2025 with a simple goal: bring enterprise-grade IT and network security expertise to businesses, practices, and offices that don’t have — and don’t need — their own IT department.
We combine senior-level technical depth with a personal, hands-on approach: one reliable contact, transparent pricing, and full control for our clients over their own accounts and data.
A professional reference letter from senior management is available upon request.
Our Foundation
Digitriva is led by a Senior Network Security Engineer with more than 11 years of experience designing, implementing, and securing enterprise networks across banking, manufacturing, and consulting industries. This experience shapes how we work with every client — whether it’s a small medical practice or a complex multi-site enterprise network.
As we grow, Digitriva is building a team to extend this same level of expertise across web development, IT support, and network engineering.
