The Substitution Decision: How Agentic NetOps Changes What You Need From Your Network Team

Agents that show their reasoning, work within limits you set, and wait for your engineer’s approval. Plus Forrester’s math to rerun with your own numbers.
Your network keeps growing, but the number of people who can run it at that scale probably hasn’t. So the same senior engineers get pulled into every escalation, and the architecture work you hired them for waits until the fire is out.
Nearly half the network professionals NetBrain polled at a recent webinar said most of their tasks are still done by hand. And many of the rest use a copilot that speeds up analysis while engineers still have to plan, execute, and verify every step. The real gap holding back agentic adoption is trust, not technical capability.
Letting an agent act on a live network only works if you can verify what it did, why, and that it stayed inside its guardrails. Without that, your engineers end up re-checking every step themselves, and the capacity you were hoping to free goes right back into verification.
Earning that trust starts with what the agent knows, not just what it’s allowed to do.
The model underneath is probabilistic. It’s right most of the time, not all the time, and a live network is an expensive place to find out when it’s wrong. It also doesn’t know your network, your standards, or how your team runs a change, only networking in general. To close this gap, you need a harness that gives the model the live network context, engineer-grade tools, and intent to reason from, and checks the result before an engineer executes anything.
When NetBrain polled network teams at a recent webinar on what keeps them from trusting AI agents on their network, about 75% stated it comes down to either: they can’t see the AI’s reasoning, or the guardrails aren’t there.
That’s a fair bar for any agentic platform to clear before it touches production. You should be able to set what each agent can access, read the evidence behind every conclusion, and find every action in an audit trail. In NetBrain, those controls live in Agent Studio. Every agent shows its plan and evidence, and every change is tagged in the audit trail.
There are guardrails built in, too. The Change Agent can’t push a change on its own – an engineer must approve it and hit execute, which is a feature that can’t be turned off. Agents can only reason about the parts of your network NetBrain can see, so coverage matters. Since AI usage isn’t free, the new Adoption and Usage Dashboard shows AI Usage and Cost through prompts, sessions, users, and token spend alongside the value you get.
Take a recent case study where a payment application started failing. The Diagnosis Agent traced the live path and found a policy denying the traffic in under two minutes. One click handed that root cause to the Change Agent, which wrote the remediation runbook with pre- and post-change checks.
Before a risky change reaches your change advisory board (CAB), the Change Agent can run a what-if analysis against live configs, paths, and neighbors, then give you a go or no-go with the evidence. In a lab rebuild of the 2021 Akamai outage, it flagged a BGP prefix limit set below what the peer was already sending.
With a CVE plug-in, the agents can also show you which devices at a site are exposed and which application paths run through them. Each of these examples is the kind of work Forrester measured when it put a dollar figure on network operations.
NetBrain commissioned Forrester Consulting to run a Total Economic Impact™ study, and Forrester interviewed five customers. Forrester combined their answers into one hypothetical company. The composite organization saw a 241% ROI over three years.
For a business use case, the more useful finding is where that return came from. Nearly 70% of the quantified benefits came from shortening significant outages – which was more than troubleshooting time, change automation, and team productivity combined.
That tells you where to point the agents first: the incidents that cost your business the most. Forrester’s model also assumes the value builds over three years as automation and shared knowledge accumulate, which is the part your team controls.
The Forrester study works best as a template, and its outage model runs on numbers you already track:
Forrester spread revenue across every hour of the year, which lowers the hourly rate, then trimmed 20% for risk. Do the same, and you’ll have a stronger internal argument.
Forrester’s Andre Kindness estimates that, “about 80% of deploying a platform like this is gathering what your team knows.” So start with one workflow you can measure before and after.
