NEW YORK & MIAMI--(BUSINESS WIRE)-- Today, Method Security and Palantir Technologies (NASDAQ: PLTR) announced the Cardinal Program, an initiative to strengthen national cyber resilience through safe, autonomous red teaming.

Cardinal will provide select municipalities, utilities, and critical infrastructure operators with opt-in, continuous autonomous security assessments at no cost.

These institutions protect the systems and services that underpin our way of life. They now face adversaries using increasingly capable AI to find and exploit vulnerabilities at unprecedented speed and scale.

Cardinal is our effort to close that gap. The program brings autonomous cyber systems, advanced AI, and expert operators together to support the teams protecting America’s essential infrastructure.

Method’s platform and security operators will map, probe, and safely test participating organizations’ internet-facing assets to identify attack paths. Frontier and open-weight models will power the assessments, helping defenders understand how attackers armed with the same capabilities might approach their systems. Palantir Foundry, AIP, and the Ontology for Cybersecurity will provide secure infrastructure for Method to integrate and deliver findings and support collaboration. AIP enables validation of repeatable, automated assessment workflows for these high-consequence missions, while the Ontology contextualizes findings in terms of real mission impact to focus response actions.

Assessments will emulate real-world adversary behavior, within scope and rules of engagement defined by participants. Safeguards and human oversight will be enforced to prevent disruption. Security experts will review the findings and provide adversary-informed hardening guidance. National cyber resilience will require urgent collaboration across industry and government. Our goal is to deliver capabilities to defenders now, while demonstrating a model that can scale. We hope Cardinal could give government agencies a proven technical vehicle to direct these capabilities toward systems within their mandates.

Attackers are putting these capabilities to work now. Defenders should not have to wait to do the same.

If your organization protects critical systems or public services, we want to hear from you.

Key Terms

red teaming technical

Red teaming is an independent, adversarial review where a group deliberately probes a company’s systems, plans or controls by thinking and acting like an attacker to find weak spots before real threats do. Think of it as hiring someone to try to break into your house so you can fix the locks; for investors, it matters because red teaming uncovers hidden risks, reduces the chance of costly breaches or regulatory problems, and can protect a company’s financial and reputational value.

open-weight models technical

Open-weight models are machine-learning systems whose internal parameters (the numeric “weights” that determine how inputs are turned into outputs) are publicly available for inspection, modification, and reuse. For investors, that transparency makes it easier to audit performance claims, assess risks and biases, and accelerate product development—think of it as a recipe where every ingredient and measurement is shown, so anyone can test, tweak, or reproduce the result.

rules of engagement technical

Rules of engagement are the agreed protocols that govern how parties interact, communicate and act during corporate processes such as takeover talks, proxy contests, board negotiations or regulatory reviews. They lay out who speaks to whom, timing, confidentiality and disclosure obligations—like a playbook that keeps a complex conversation orderly. Investors care because these rules determine how and when material information is shared, which affects transparency, timing of decisions and potential price movement.
