Federal networks are reaching a turning point. For decades, agency wide area networks were designed for a world of predictable traffic, centralized data centers, and applications that rarely moved. That world is gone. Cloud services, mobile-first workforces, and data-heavy tools like artificial intelligence and real-time analytics have made older architectures built on MPLS and leased lines a poor fit for today’s mission demands.

The ACT-IAC white paper, “Modernizing Federal Networks from the Campus and Beyond,” lays out a framework for what comes next. We are proud that Mohamed A. Hersi, our Chief Strategy and Innovation Officer, was part of the team of government and industry contributors who helped shape this document. The work reflects the questions we hear from agencies every day, and lines up closely with where we focus at ACI: federal IT, cybersecurity, and network modernization.

Why legacy networks fall short

Traditional network designs prioritized stability and perimeter security. Those qualities mattered, but they came at the cost of flexibility. As agencies adopt cloud platforms and support a distributed workforce, routing every connection through a handful of centralized inspection points creates bottlenecks, drives up cost, and slows the mission.

The security model has shifted just as sharply. With sensors, tactical devices, and remote users multiplying, every access point is a potential entry for an adversary. Perimeter-only defenses no longer hold. Security must be built into the network itself, validating users and devices continuously rather than trusting anything by default.

Artificial Intelligence (AI) raises the stakes further. It is not just another application competing for bandwidth. Training clusters, distributed inference, and machine-to-machine communication create bursty, unpredictable traffic that stresses even modernized infrastructure. A network built purely for stability can become the very thing that slows a mission down.

The Future-Agile Network (FAN)

The white paper introduces the idea of a Future-Agile Network, or FAN. Rather than a single product, it describes an approach: design the network to expect change instead of resisting it. The Future-Agile Network blends traditional network connections such as fiber with 5G and 6G, and low-earth-orbit satellite connectivity so traffic can shift paths when conditions change. It uses AI-assisted management to spot problems early and reroute around them. And it treats compliance with standards like FISMA, FedRAMP, and TIC 3.0 as an outcome of good design rather than a hurdle bolted on at the end.

Several building blocks make this possible:

Beyond automation: the self-driving network

One of the more forward-looking sections describes where this heads next. SD-WAN is not the finish line; it is the foundation for networks that manage themselves. The paper walks through Intent-Based Networking, where engineers declare the outcome they want, such as reliable, jitter-free video for a mission team, and the system translates that intent into configuration, deploys it, and continuously checks that it is being met. Paired with Self-Organizing Networks that configure, optimize, and heal themselves, the network starts to behave less like static plumbing and more like a system that adjusts in real time within the guardrails people set.

The point is not to remove human expertise. It is to shift skilled staff from constant firefighting toward strategy and oversight, while the network handles routine correction on its own.

The real-world challenges

The paper is honest about the obstacles, and this is the part we find most useful in conversations with agencies. Modernization is not only a technology decision. It runs into legacy technical debt, where decades-old systems cannot support modern authentication or encryption. It runs into multi-cloud complexity, where inconsistent policies across providers create security gaps. It runs into supply chain risk, where agile networks depend on complex software stacks that must be vetted carefully. And it runs into a workforce skills gap, as network engineering increasingly demands automation and coding skills alongside traditional networking knowledge.

None of these are reasons to wait. They are reasons to plan deliberately, and to treat modernization as a program rather than a single purchase.

A staged path, not a forklift

Encouragingly, the paper frames the journey as a maturity model rather than an all-or-nothing leap. Agencies move from legacy WANs with static security, through hybrid SD-WAN and early Zero Trust adoption, into scaled multi-cloud environments with AI-assisted operations, and finally toward a fully adaptive, AI-optimized edge with continuous compliance. Agencies that have already invested in SD-WAN have a genuine head start, since much of the foundation for an intelligent, self-correcting network is already in place.

The network is the backbone of everything an agency delivers.

Our perspective

At ACI Solutions, this framework mirrors the questions federal agencies are already asking: how to modernize without sacrificing security, how to control cost while improving resilience, and how to prepare networks for the demands of AI. The answer is rarely a single upgrade. It is a deliberate, mission-aligned strategy that treats the network as the backbone of everything an agency delivers.

We are grateful to ACT-IAC and to the government and industry colleagues who collaborated on this work, and we are glad our team could contribute to it.
