TL;DR
In a live experiment, five AI models managing a simulated company successfully refused a sophisticated phishing attempt. The test highlights both progress and remaining vulnerabilities in AI security under pressure.
Five AI models managing a simulated software company successfully resisted an escalating impersonation attack, refusing to share sensitive customer data despite persistent pressure. This live experiment demonstrates that AI systems can maintain trustworthiness under targeted social engineering attempts, a critical concern for AI security as these models are integrated into real-world business operations.
The experiment, conducted by Firmulate, involved five different AI models each tasked with running the same small software company through a simulated week of crises and manipulations. The models faced a staged attack from a fake CEO requesting customer lists and approval bypasses. All five models identified and refused the deception, adhering to security protocols designed to prevent breaches.
Despite unanimous refusal, only two models successfully completed their core business tasks, such as signing a €55,000 deal. The others declined to finalize deals, often due to missing critical internal information, revealing a trade-off between security and operational efficiency. The results suggest that while AI models can be programmed to refuse malicious requests, they may still struggle with completing complex tasks when faced with security vulnerabilities.
This experiment provides evidence that AI models can be trained to recognize and refuse social engineering tactics, a vital step toward deploying AI securely in customer-facing and sensitive environments. The ability of all models to detect and decline impersonation attempts under pressure suggests a meaningful advance in AI security protocols. However, the fact that some models failed to complete their tasks highlights ongoing challenges in balancing security with operational performance, emphasizing the need for further refinement before widespread adoption.

Live AI Security Testing in Business Simulations
The experiment is part of an ongoing effort by Firmulate to evaluate AI models in real-world management scenarios, simulating crises and manipulative tactics. Previous benchmarks have focused on chat quality and reasoning, but this live test emphasizes security and trustworthiness. The models tested include multiple vendors, with results showing that even sophisticated AI can be programmed to prioritize security over compliance, but with notable limitations.
“All five models refused the impersonation attempt, demonstrating that AI can be trained to uphold trust even under pressure.”

Key Questions
Can AI models reliably detect and refuse phishing attempts?
According to the recent experiment, all tested models successfully refused the staged impersonation attack, indicating that AI can be trained to recognize and decline malicious requests under pressure.
Did the AI models complete their business tasks during the test?
Only two of the five models managed to finalize a key deal, while the others declined, often due to missing internal information, highlighting a trade-off between security and operational performance.
What are the limitations of this live security test?
The experiment was conducted in a controlled simulation, and it is unclear how the models will perform in real-world environments with more complex or varied threats. Scaling these results remains a challenge.
Why is this experiment significant for AI deployment?
This live test demonstrates that AI models can be programmed to prioritize security and trustworthiness, a key concern for deploying AI in sensitive or customer-facing roles.
