Proofpoint will take part in OpenAI’s Daybreak Cyber Partner Program, which gives vetted cybersecurity organizations governed access to frontier AI. The company said so in a June 17 blog post that tied its selection to the launch of GPT-5.5.
Proofpoint described AI as a double-edged tool. Defenders can use it to improve detection, investigation and response. Attackers can use it to scale social engineering, move faster and exploit vulnerabilities across connected environments.
The company’s 2026 AI and Human Risk Landscape report put numbers on the strain. Half of the organizations surveyed had experienced a confirmed or suspected AI-related security incident, and 87 percent had deployed AI assistants beyond the pilot stage. More than half lacked full confidence that their existing controls would catch a compromised AI system.
What Proofpoint plans to do
Inside Daybreak, Proofpoint says it will work with OpenAI on trusted defensive uses. Those include accelerating threat investigations, enriching and prioritizing alerts, improving intelligence analysis, streamlining incident response and raising analyst productivity. The company said these could help organizations scale defensive operations while easing the burden on stretched teams.
It also keeps building Satori, its agentic AI offering. Satori is meant to let defenders boost scale and agility, and to make sure routine work like alert triage happens at machine speed. OpenAI models already run inside it. Proofpoint expects GPT-5.5 may add capabilities.
Responsible deployment is a core piece of the program, the company wrote. Proofpoint and OpenAI, it said, share a commitment to AI governance, monitoring, safety controls and abuse prevention.
