Method Security builds autonomous security software for large enterprises and government. Its platform automates defensive and offensive cyber work, including discovering external vulnerabilities, deploying agents, moving laterally, and testing cloud accounts without human input, while also including red-team style simulations. The company differentiates itself with a veteran team from Palantir, NSA, CrowdStrike, AWS, and the U.S. military, and by focusing on mission-critical and government customers with a broad set of security capabilities called “security superpowers.” Its goal is to provide adaptive, proactive cybersecurity that protects critical infrastructure against rapidly evolving threats.

Simplify's Take
What believers are saying
- 2025-11-19: Method raised $26 million from a16z, General Catalyst, and Blackstone.
- 2026 SBIR awarded $1.25 million to adapt Method for Space Force operations.
- Method already serves DoD, federal agencies, and Fortune 500 customers, signaling real procurement traction.
What critics are saying
- Method depends on OpenAI partnerships; access changes would cripple product differentiation within months.
- Government sales depend on opaque Pentagon channels; renewal failure would hit revenue immediately.
- Adversaries and larger vendors can copy autonomous red-teaming, compressing Method's premium by 2027.
What makes Method Security unique
- 2025-12-03: OpenAI integrated frontier models into Method's cyber defense platform.
- Method fuses offensive and defensive workflows into one autonomy framework for operators.
- 2026-06-02: Trusted Access for Cyber gives customers direct frontier-model access through Method.

↑ 0%Method Security and OpenAI partner to accelerate A.I. for U.S. National Security cyber missions. Method Security and OpenAI today announced a strategic partnership to responsibly deploy A.I. capabilities for U.S. national security cyber missions. The companies will integrate OpenAI's state-of-the-art models into Method's platform, built to operationalize A.I. for cyber defense. The partnership aims to give national security cyber operators a force-multiplying advantage to strengthen readiness and counter increasingly sophisticated threats. U.S. cyber operators defend the world's largest and most complex attack surface against rapidly advancing nation-state and criminal actors. National cyber readiness is essential to credible deterrence against near-peer adversaries. Meeting this challenge requires safely deploying A.I. at scale to re-secure critical institutions and proactively deter adversaries. Method and OpenAI are developing a joint solution for cyber operators across the Department of Defense and Intelligence Community. By embedding OpenAI's models within Method's cyber-specific infrastructure, the platform delivers scalable, secure advantages in mission environments. "Method was founded to deliver cyber resilience to critical institutions, including the U.S. national security apparatus," said Sam Jones, CEO and Co-Founder of Method Security. "By combining OpenAI's leading A.I. models with our platform, we can realize that mission. The future of cyber will be won by those who safely harness autonomy at scale." "OpenAI is committed to ensuring A.I. strengthens U.S. resilience," said Katrina Mulligan, Head of National Security Partnerships at OpenAI. "Nowhere is this more vital than in cybersecurity. In Method Security, we have a partner aligned on delivering unmatched capabilities to U.S. cyber defenders - responsibly and ethically." The partnership reflects a shared belief that the future of cybersecurity depends on responsible innovation and continuous readiness. As adversaries weaponize A.I., Method and OpenAI are ensuring the United States leads not only in A.I. development but in its safe, ethical, and effective application to national defense.
A16z, General Catalyst lead $26m round in cybersecurity firm Method. Method Security, a dual-use cybersecurity company combining cyber expertise with AI speed, has raised US$26 million across its seed and series A rounds. Andreessen Horowitz led the seed round, while General Catalyst led the series A, with participation from Blackstone Innovations Investments, Crossbeam Venture Partners, Forward Deployed Venture Capital (VC), and Pax Ventures. Method Security offers offensive and defensive cybersecurity tools, such as autonomously mapping attack paths and red-team testing. Early customers included Blackstone and a Defense Department organization. The company's team includes alumni from AWS, CrowdStrike, and Palantir Technologies. Method Security now has a number of Pentagon deals under its belt, said CEO Sam Jones. Food for thought. Pentagon deals hint at progress, scope still unclear. * Method Security CEO Sam Jones said the company has several Pentagon deals. It has not shared award amounts or the government procurement channels (contract vehicles) used, so the scope is still unclear. * Backers include Blackstone Innovations Investments and Forward Deployed Venture Capital (VC). Sustained revenue will depend on renewals and wins across more Department of Defense (DoD) agencies. * Red-team testing and attack path mapping fit DoD zero-trust initiatives, a security model that assumes no user or device is trusted by default. Method could win multi-year service contracts if it keeps surfacing novel vulnerabilities. Managed security providers can tap rising breach simulation demand. * Active Requests for Proposals (RFPs) for Breach and Attack Simulation (BAS) tools, software that emulates real-world attacks to test defenses, have appeared in several markets. Examples include a September 2025 request from SBI Securities (a Japan-based brokerage), plus late-2025 bids in Oman (October) and Qatar (November to December). Buying looks near term for financial institutions and government entities. * Managed Security Service Providers (MSSPs) and IT systems integrators can go after these buyers with managed BAS. Bundle Security Information and Event Management (SIEM) integration with continuous monitoring to ease the effort of running autonomous red-teaming tools (automated software that simulates attacker behavior) in-house. * Compliance-focused firms can package BAS with Federal Risk and Authorization Management Program (FedRAMP) support or Authority to Operate (ATO) help. U.S. federal buyers often require offensive testing with documentation to meet zero-trust timelines. How would you feel if you could no longer use Tech in Asia?
