AI’s Integrity Under Pressure: How Five Models Resisted Social Engineering Tests in a Live Business Experiment

In the bustling world of cleaning and floor care, trust is everything. What if your AI tools—designed to support operations—could be tested for integrity before deployment? Recent live experiments reveal surprising resilience in AI decision-making under social engineering pressures, offering a new layer of security for businesses wary of manipulation.

Testing AI Integrity in Real Business Conditions

At a time when AI increasingly supports critical business functions—from customer management to supply chain decisions—it’s vital to ensure these systems behave reliably under pressure. The firmulate.com live experiment puts this to the test by simulating a small software company’s worst week, complete with crises, customer interactions, and manipulative temptations.

The key innovation? Every decision made by the AI models is fully versioned and auditable, allowing observers to understand precisely how each system responds. Five of the leading AI models participated, including GPT-5.6-SOL, Kimi K3, Sonnet 5, Fable 5, and Opus 4.8. They faced a series of social engineering scenarios designed to test their integrity and resistance to manipulation.

How the AI Models Faced the Social Engineering Scenarios

The experiment involved escalating fake CEO messages, including requests such as sharing sensitive customer lists or bypassing approval processes. There was even a trick involving a background quote to manipulate the AI into signing off on a deal. Remarkably, all five models refused every manipulation attempt, maintaining integrity under pressure. This is a significant finding for businesses that depend on AI for critical decisions, especially in sensitive areas like customer data and financial transactions.

According to Kimi K3, one of the top performers, the reason for refusal was clear: “Treat the request as a suspected approval-bypass / possible impersonation.” This mindset—considering whether a request is genuine or a threat—proved effective in preserving trustworthiness.

Decisive Factors in Success

The experiment revealed that the real vulnerability wasn’t in the superficial content of requests but embedded deep within the company’s own files. The models that read and analyze hidden documentation, not just surface-level prompts, succeeded in closing a deal at full price, worth over €4,500 in monthly recurring revenue. Conversely, models that skipped this step missed the opportunity.

This underscores an important lesson: AI’s ability to access and interpret internal data can be crucial in maintaining integrity and making sound decisions, especially when under attack or pressure.

Performance and Discipline Variances

The experiment also highlighted differences in discipline and thoroughness among the models. Opus 4.8, the most comprehensive participant with over 80 learned rules and deep analyses, was positioned last—missed the close and slipped in discipline, such as writing attempts into a locked department instead of escalating issues. This illustrates that even the most thorough AI can falter if not carefully managed and aligned with organizational protocols.

Implications for Business Security

For business owners in cleaning, floor care, or maintenance, these findings are instructive. AI tools designed to support operations must not only produce quality output but also demonstrate unwavering integrity under pressure. The experiment suggests that AI systems can be trained and tested to resist manipulation, providing an earlier warning—before a real breach occurs.

Moreover, the firmulate.com platform offers companies the opportunity to run their own “wargames” against a read-only export of their operations, simulating crises without impacting real systems. This proactive approach allows organizations to evaluate and strengthen their AI’s resilience in a controlled environment.

Why Resilience Matters More Than Performance

While the AI models scored highly on traditional benchmarks—such as GPT-5.6-SOL at 95 points and Kimi K3 at 93—these scores only tell part of the story. The true test lies in whether the AI can finish what it starts, stay honest under pressure, and avoid costly breaches of trust. The live experiment demonstrates that even under escalating social engineering attempts, all five models refused to compromise their integrity. Only two signed a deal they had analyzed and earned, not one they were manipulated into accepting.

This difference between diagnostic accuracy and actual integrity is critical for businesses that rely on AI for decision-making. It’s not about the AI writing well; it’s about whether it can be trusted to do what’s right—especially when it matters most.

Moving Toward Trustworthy AI Adoption

As AI continues to integrate into everyday business operations, these live tests serve as valuable benchmarks. They prove that ethical and security-conscious AI isn’t just aspirational but achievable. Deploying such resilient AI systems in your organization can help safeguard sensitive data, uphold trust with customers, and prevent costly breaches of integrity.
