OpenAI Urges Cyber Defense Push as Palo Alto Networks, Mate Security & ServiceNow Sign On

New York, United States, September 7th, 2026, FinanceWire

The cybersecurity industry is entering a new phase as artificial intelligence begins to reshape not only how organizations defend their systems, but also how attackers target them. Against that backdrop, OpenAI today issued an open letter, “A Call to Action on Cyber Defense,” urging industry, governments and technology companies to move quickly to strengthen digital defenses before AI-enabled attacks become significantly more widespread.

Among the first companies to sign the initiative are Palo Alto Networks, Mate Security, and ServiceNow, placing the cybersecurity companies among a select group of market leaders backing OpenAI’s call from its first day. The participation is particularly notable for Mate Security, one of a relatively small number of cybersecurity companies building around an agentic approach to cyber defense.

A Narrow Window For Defenders

The letter, issued by OpenAI CEO, Chairman and Co-Founder Greg Brockman, argues that the cybersecurity community has a limited opportunity to take advantage of AI’s current capabilities before attackers gain even greater access to increasingly sophisticated models.

“We have a limited window to strengthen cyber defenses,” the letter states.

OpenAI argues that AI-enabled attacks are likely to become substantially more capable in the coming months, creating new risks for organizations responsible for everything from healthcare and water systems to the infrastructure underlying the internet.

At the same time, the company sees AI as an opportunity for defenders to address longstanding weaknesses that have accumulated across enterprise environments.

“Today’s AI advances are already giving defenders new ways to fix weaknesses that have accumulated for years,” the letter says. “If we act decisively, we can use the defenders’ window to make our digital world much more secure.”

That tension—between accelerating offensive capabilities and the opportunity to equip defenders with comparable technology—is becoming one of the defining questions in cybersecurity.

From Security Tools To Agentic Defense

The OpenAI initiative calls for a fundamental expansion of how AI is used across cybersecurity. Rather than limiting AI to individual security functions, the letter advocates putting cyber-capable AI directly into the hands of defenders and using it to improve everything from vulnerability remediation and threat detection to incident response.

The call is built around three core principles: recognizing that existing security practices will not be sufficient, empowering more defenders with cyber-capable AI, and mobilizing a collective response.

For cybersecurity companies, OpenAI specifically calls for continuous testing against frontier cyber capabilities, AI-enhanced security products, greater collaboration across technology ecosystems and practical assistance for critical infrastructure operators.

It also calls for sharing threat intelligence and tested playbooks, with progress measured by tangible outcomes—including how many organizations are protected, how quickly attacks are contained and whether fixes actually work.

Why Mate Security’s Participation Matters

Mate Security’s inclusion places the company within a broader movement toward what could become the next generation of security operations: agentic cyber defense.

Traditional security automation has often depended on predefined rules and playbooks. But as environments become more dynamic—and attacks increasingly incorporate AI—the ability for security systems to reason through investigations, adapt to changing circumstances and execute multi-step defensive actions is becoming increasingly important.

Mate Security is building an open foundation for agentic cyber defense, including its Gamebooks approach for structuring investigations so AI agents can reason, pivot and act while operating within defined procedures.

That makes its participation in OpenAI’s initiative especially relevant. The letter is not simply a call for more AI in cybersecurity; it is a call for a new defensive architecture capable of operating against increasingly autonomous threats.

A Collective Security Mandate

OpenAI is ultimately positioning cyber defense as a collective responsibility rather than a problem any single vendor can solve.

“No single company should control the future,” the letter states, while calling for new partnerships to raise security standards and address emerging threats.

For the companies, becoming first-day signatories signals alignment with that broader direction. It also highlights a growing divide in cybersecurity between companies adding AI capabilities to existing products and a smaller group building security infrastructure around AI agents from the ground up.

The stakes are likely to rise as AI capabilities continue advancing. OpenAI’s message is straightforward: defenders cannot wait for the next generation of attacks to arrive before adapting.

“We can make the digital infrastructure we all depend on more secure,” the letter concludes. “Let’s put them to work.”
