TL;DR
In a live benchmark, five AI models from different vendors successfully refused a simulated impersonation attack attempting to manipulate company decisions. The experiment demonstrates progress in AI security but also reveals limitations in completing tasks under pressure.
Five AI models from different vendors successfully refused an escalating impersonation attack during a live management simulation, demonstrating significant progress in AI security protocols. This experiment, conducted by Firmulate, tested whether AI agents could resist manipulation while managing a small software company under pressure, a critical concern for AI deployment in real-world business environments.
The experiment involved five AI models running a real-time, live simulation of a small software company’s weekly operations, including sales, negotiations, and decision-making. Each model faced a staged attack where a fake CEO attempted to influence decisions by requesting sensitive information and approvals. All five models identified and refused the impersonation attempts, citing security protocols and suspicion, as documented in their public reasoning archives.
While all models demonstrated strong resistance to manipulation, only two successfully completed a key business transaction—signing a €55,000 deal—based on their analysis. The other models identified the threats but failed to act on critical information buried within the company’s files, leading to lost revenue opportunities. The results are part of a continuous, publicly accessible benchmark run, with over 680 decision points recorded, providing transparency and ongoing testing of AI integrity under stress.
What This Means for AI Security in Business
This experiment shows that AI models can effectively recognize and refuse sophisticated impersonation attempts, a vital capability for deploying AI in sensitive business contexts. The ability to resist manipulation under pressure enhances trust and safety in AI systems used for management and decision-making. However, the variability in task completion highlights ongoing challenges in ensuring AI can also deliver consistent operational results, not just security.

Live Benchmarking of AI Trustworthiness and Performance
Earlier in 2026, multiple AI vendors began releasing models with enhanced security features aimed at preventing manipulation and impersonation. The Firmulate experiment is part of a broader effort to evaluate AI reliability in real-world scenarios, moving beyond chat-based tests to full operational simulations. This live, public benchmarking builds on prior research but is unique in its transparency and continuous nature, with real-time results and detailed decision logs.
The experiment’s setup involved a simulated company with real financial mechanics, including payroll and revenue, to mimic actual operational pressures. The staged attack escalated over three stages, testing the models’ ability to detect and refuse manipulation at each step. The results indicate that while security protocols are effective, operational performance under pressure remains inconsistent across models.
“All five models refused the impersonation attempts, demonstrating a significant step forward in AI security under real-world pressures.”

Unanswered Questions About AI Operational Reliability
It remains unclear whether these models can consistently perform complex business tasks under different types of pressure or in more varied scenarios. The experiment focused on a staged impersonation attack; other forms of manipulation and real-world unpredictability are still untested. Additionally, the long-term robustness of these security features as models evolve is still unknown.

Key Questions
What does this experiment demonstrate about AI security?
The experiment shows that current AI models can effectively recognize and refuse impersonation and manipulation attempts in a live management scenario, marking progress in AI trustworthiness.
Are these results applicable to real-world business AI systems?
While promising, these results are based on a controlled simulation. Real-world environments may introduce additional complexities, and ongoing testing is needed to confirm applicability.
Did any of the AI models complete all their tasks during the test?
Only two models successfully signed a key business deal, while others identified threats but failed to act on critical information, highlighting ongoing operational challenges.
What are the limitations of this experiment?
The staged attack was specific to impersonation; other attack types and unpredictable scenarios remain untested. Long-term robustness of security features is also still uncertain.
What will happen next in AI security testing?
More comprehensive live benchmarks are planned, with broader attack scenarios and continued model improvements, aiming to enhance both security and operational performance in real-world applications.
