OpenAI is moving to strengthen its security credentials with a major acquisition, while simultaneously dealing with internal fallout from its expanding work with the U.S. military.

Security First: Promptfoo Acquisition

The company announced on March 9 that it is acquiring Promptfoo, an AI security platform that helps enterprises identify and remediate vulnerabilities in AI systems during development. The deal marks OpenAI's continued push into the enterprise market and signals growing concern about AI security risks.

Promptfoo's platform allows developers to test and evaluate AI systems for security weaknesses before deployment. By bringing this capability in-house, OpenAI aims to offer more robust security features to its enterprise customers and address rising concerns about AI agent vulnerabilities.

The acquisition comes as AI agents increasingly handle sensitive business functions. "Security is foundational to building trust with enterprise customers," an OpenAI spokesperson said. "Promptfoo's expertise will help us identify vulnerabilities earlier in the development cycle."

Pentagon Fallout: Executive Resignation

Not all OpenAI employees are happy with the company's direction. Caitlin Kalinowski, who led OpenAI's hardware and robotics initiatives, resigned on March 7 in response to OpenAI's deepening involvement with the Pentagon.

Kalinowski's departure highlights ongoing tensions within OpenAI between its civilian AI research mission and the reality of pursuing government contracts. The company has been expanding its defense-related work, including partnerships with U.S. military agencies.

Her resignation sent a ripple through the AI research community, with some researchers expressing concern about the direction of frontier AI development toward military applications.

Product Delays Continue

Meanwhile, OpenAI continues to face challenges on the product front. The company has again delayed the rollout of ChatGPT's so-called "adult mode" — a feature that would allow more mature content generation capabilities. The delay marks the second postponement, frustrating users who have been waiting for expanded content policies.

OpenAI has not specified a new timeline for the feature, citing ongoing safety considerations.

Looking Ahead

These developments paint a picture of an organization juggling multiple priorities: securing its technology stack, managing internal morale around military work, and delivering on product promises. The Promptfoo acquisition is expected to close in the coming weeks, while the fallout from Kalinowski's departure may continue to shape internal discussions about OpenAI's strategic direction.

The company faces pressure on multiple fronts — enterprise customers demanding better security, employees questioning defense contracts, and users waiting for product features. How OpenAI navigates these competing interests will shape its trajectory through 2026.
