Executive Summary
Security teams build resilient AI agents by giving agents realistic experiences of threats they have not yet encountered, then using that evidence to teach new skills. Hyper-synthetic data lets us explore plausible future attacks while keeping the learning grounded in how systems and people actually behave. That creates a path to faster development and more convincing customer evidence, provided we test whether the learning holds up in unfamiliar situations.
Key Takeaways
- Historical intelligence is the starting point for teaching agents to handle what might happen next.
- Realistic infrastructure, interfaces, and activity make simulated experience useful for learning.
- Curated hypersynthetic data supports training; separate tests show whether the agent learned.
- Reusable scenarios can accelerate development and strengthen customer proofs of value.
Build: Give Agents Experience Beyond What We Already Know
If we want an AI agent to investigate an attack it hasn’t seen, we have to give it more than a record of attacks we already understand. Historical data provides an essential foundation, but the adversary keeps moving. An actor can pursue the same objective through a different identity, application, or sequence of actions. The agent needs experience making sense of those unfamiliar situations, and waiting for them to happen to a customer is a costly way to provide it.
This is why security teams must build AI agents with hyper-synthetic data. We create a realistic environment, explore what could happen inside it, and use the resulting evidence to teach the agent new skills. Historical intelligence tells us how an adversary operates and what it is trying to accomplish. Simulation lets us generate future-facing permutations of that behavior, so the learning can reach beyond the incidents we already have on file.
Google DeepMind’s GraphCast offers a useful analogy. It was trained on four decades of historical weather reanalysis data to predict conditions up to ten days ahead. The value comes from using the past to help understand what might happen next. Cybersecurity adds another challenge because our adversary makes choices and adapts to the defense. A realistic simulation gives us somewhere to explore those plausible choices and generate evidence about their consequences.
Realism: The Experience Has to Mean Something
Imagine we are building a threat hunting agent. We want it to recognize when an ordinary-looking login becomes part of a larger compromise. To learn that skill, the agent needs to see how the account relates to the endpoint, what the user normally does, which application was accessed, and what happened afterward. An attack label by itself cannot provide that understanding. The relationships surrounding the event are what give it meaning.
This is why the environment needs three layers of realism. Infrastructure supplies the relevant IT, cloud, OT, IoT, and industrial systems, including real hardware where its behavior matters. The interface layer supplies the applications, security tools, agents, identities, and data inside those systems. The activity layer brings them to life through users doing their jobs, machines exchanging traffic and producing logs, and adversaries pursuing their objectives.
When those layers work together, we can generate hypersynthetic data from activity that has observable consequences. The level of detail should follow the skill we want to teach. An identity investigator needs convincing account behavior and security evidence; an industrial response agent may also need to understand what happens to a process when a controller is isolated. We build the conditions that make the decision meaningful.
Learning: Let the Agent Encounter More Than a Perfect Scenario
Now put a red agent into that environment with an objective grounded in threat intelligence, such as reaching sensitive information. Let it explore different routes to that objective within the exercise’s boundaries. A blue agent investigates through the security tools, while a separate control or evaluation function records what actually happened. We can then compare the defender’s interpretation with the actions that took place, including the legitimate activity around them.
Some investigations will go well. Others will stall because a log is missing, an assumption is wrong, or perfectly normal administration looks suspicious. Those experiences are valuable. If we only teach an agent with clean examples where every clue points toward the answer, we shouldn’t be surprised when it struggles with a messy environment. We want the agent to learn how to pursue evidence, revise a conclusion, and recognize when a human needs to intervene.
The records from those encounters become training material after we check their quality and labels. Depending on the design, that material can support model fine-tuning, training from evaluated feedback, or improvements to the agent’s instructions and procedures. Running an exercise doesn’t automatically retrain a model; this is the point where the engineering team deliberately turns experience into learning. Repetition gives us more opportunities to teach, provided we keep the examples useful.
Hyper-Synthetic Data: Four Advantages Make the Effort Worthwhile
The attraction is that we can shape the experiences we need instead of accepting whatever data happens to be available. That opens up four advantages, each of which matters to the people paying for, building, and governing the agent.
| Attribute | What it makes possible | How we keep the advantage real |
|---|---|---|
| Privacy & governance | Collaborate using controlled identities, scenarios, and datasets. | Govern sensitive inputs, access, retention, and permitted uses. |
| Economics | Reuse environments and useful datasets across development work. | Account for generation, labeling, storage, and quality assurance costs. |
| Time | Explore plausible conditions before an incident forces us to confront them. | Keep scenarios technically possible and relevant to the skill. |
| Accuracy & fidelity | Observe actions and outcomes directly to establish reliable labels. | Validate both real and synthetic evidence against the intended use. |
These advantages work best when historical and simulated evidence inform each other. Real observations keep the scenarios grounded, while simulation lets us explore gaps and variations that are difficult to obtain elsewhere. We can create more examples of a rare identity abuse pattern, for instance, and then check that the systems produce the behavior we expected. That’s a much stronger basis for learning than assuming a dataset is useful simply because it is large.
Gartner highlights this massive shift: in 2025, HSD accounted for just 15% of AI training data in sectors like defense, manufacturing, and transportation. By 2030, Gartner predicts that number will surge to 80%.

Proof: Show That the Agent Survives an Unfamiliar Situation
Once we have trained the agent, I want to know whether it can carry that learning into a situation it has not practiced. That means keeping evaluation scenarios separate from the training material, including different attack paths, legitimate lookalikes, and missing information. Holding out entire scenario families helps us avoid mistaking familiarity with a particular exercise for a capability we can depend on.
For a triage agent, we can examine whether conclusions improve, false alarms fall, investigations become faster, and escalation happens when it should. For an incident response agent, we also need to see whether the action contains the threat without unnecessary disruption. Comparing versions under equivalent conditions tells us where the investment is paying off and where more work is needed.
This also changes the product development conversation. Engineers can recreate a difficult situation, improve the capability, and exercise it across different customer contexts without starting over each time. Those reusable environments can shorten research and development cycles and give a proof of value something concrete to demonstrate. As customers see the agent handle more of their work reliably, there is a stronger basis for adoption, continued use, and expansion.
The opportunity is to give security AI a broader education before we depend on it. We can use what we know about the past to explore what might come next, turn those experiences into training, and show whether the resulting skill actually works. That makes building a continuing process of developing useful capability as the environment and the adversary evolve.
