In-depth profile of Deepfield Networks (Nokia)in Ann Arbor's tech ecosystem
Deepfield Networks was one of the quieter but more important Ann Arbor networking success stories. Founded in 2011 by Craig Labovitz, a former Arbor Networks and U-M researcher, Deepfield built network analytics software that gave ISPs, content providers, and cloud operators unprecedented visibility into the traffic flowing through their networks. Nokia acquired the company in 2017, and the Deepfield product remains a core piece of Nokia's IP networks portfolio.
The technical work is deep packet analytics at internet scale. Deepfield's engine can characterize huge volumes of network traffic in real time, attributing flows to applications, services, and content sources with a fidelity that legacy netflow tools never approached. That visibility matters because modern networks are dominated by a handful of massive video, cloud, and application traffic sources, and operators that cannot see what is happening in their networks cannot plan capacity, detect DDoS attacks, or deliver the quality their customers expect.
The Ann Arbor heritage is pure local DNA. Labovitz came from the same Arbor Networks lineage that produced Duo Security and Censys, and the company was built with U-M-adjacent engineers who had spent careers thinking about large-scale network traffic. Deepfield's acquisition by Nokia folded the technology into the global telecom vendor stack, but the Ann Arbor engineering presence has remained a critical part of the product roadmap.
For network engineers, distributed systems developers, and security-adjacent infrastructure specialists, Nokia's Deepfield team is one of the more interesting local seats. The work ships into major ISPs and cloud operators worldwide, the team carries the intellectual lineage of the Ann Arbor security and networking community, and the Ann Arbor quality-of-life package applies as it does across this list.
