Method Security

Method builds full-spectrum security products to deliver cyber resilience to America's critical institutions.

[Method Security @method_security]

Method is building autonomous cyber systems for the U.S. Government and critical enterprises.

America is facing perpetual cyber conflict. With AI accelerating the speed and scale of attacks, U.S. cyber operators need new capabilities to stay ahead.

Method is delivering those capabilities.

We are building the command-and-control layer for autonomous cyber operations. Our products fuse offensive and defensive capabilities into a full-spectrum platform, enabling security teams to achieve true visibility, challenge their estates, and outpace their adversaries.

Today, Method is deployed across the Defense Department, U.S. Federal Government, and Fortune 500.

We've raised $26M from @a16z, @generalcatalyst, @blackstone and others. This funding accelerates our mission to equip the security teams defending what matters most.

Palantir calling out what we're hearing from our customers at Method: compliance theater doesn't stand a chance against adversaries armed with LLMs.

Their security team has set the bar for years. Awesome to see @ssankar and the team raise it with a new standard for readiness.

[Sam Jones @___sjones]

Last year my position was AI was predominately accelerating known TTPs. Now it is helping generate new ones.

The threat is evolving, so must our readiness. Cyber resilience is not optional.

Discussed this + more with @AnneNeuberger.

[Taylor Morgan @tldrmorgan]

Excited to see this from Method. Having worked with @___sjones, @dan__kelly, and @seanhacker in high-stakes environments, I know how deeply they understand the mission and the stakes.

AI will redefine cyber operations, and this is a strong move toward the future we need.

[Sean Hacker @seanhacker]

U.S. Government cyber operators deserve both bleeding edge frontier models and world class software in order to supercharge their capabilities. We're delivering trustworthy autonomy to the mission environments where operators need it most.

[Method Security @method_security]

Method and OpenAI have formed a strategic partnership to deploy AI capabilities for U.S. National Security cyber missions.

U.S. cyber operators defend the largest and most complex attack surfaces on earth. As adversaries weaponize AI at scale, national cyber readiness now depends on safely deploying autonomy to re-secure our critical institutions.Method and OpenAI are developing a joint solution for the Defense Department and Intelligence Community.

By embedding OpenAI’s frontier models into Method’s cyber operations infrastructure, we’re delivering scalable, secure autonomy that powers resilience and gives defenders a force-multiplying advantage.

“I guarantee you the most sophisticated [nation-state] actors are not using vanilla Claude code to run their operations.

That’s ludicrous.

Our adversaries have better models at home that they make themselves.” @___sjones, CEO Method Security

[Jillian Williams @Jillwillnyc]

Super pumped for @dan__kelly , @___sjones , Sean and the rest of the @method_security team! Awesome mission to rebuild cyber security platform for today's risks

[Mark Crane @CraneMcrane]

Today we announced our investment in @method_security, partnering with @___sjones, @dan__kelly, Sean and the incredible team to build the autonomous future for cybersecurity. A little story about how this happened… (1/5)

[David Aron Levine @davealevine]

For those looking for American leadership in AI and Cybersecurity look no further than @method_security

Outstanding team pioneering the future of resilience for our Mission Critical Cyber Defense.

Onward!

🇺🇸 🚀

[Sam Jones @___sjones]

Excited to be on the stream today talking our fundraise and everything national cyber resilience.

[Ryan Noon @internet_meme]

Congrats to this crew! Proud to have written a small check a while back.

[scott belsky @scottbelsky]

congrats @dan__kelly and team on the progress towards a vital need here…

[Isaac Hasson @isaachasson]

Our country, military, critical infrastructure and industries were always an enormous attack surface in a future war, one that has become much more vulnerable in the age of AI. So proud of this team building the systems needed to restore advantage to U.S. defenders.

[a16z @a16z]

Today, we’re excited to share that we’re backing @method_security as they come out of stealth.

With adversaries using AI to scale threats to new magnitudes, the American government and other critical US institutions are not equipped for today’s cyber conflicts.

Method integrates diverse data sources into a digital twin, providing security teams with complete visibility and allowing for sophisticated simulations of autonomous attacks.

[Daniel Kelly @dan__kelly]

Excited to share what we've been working on at Method and announce our $26M in funding from Andreessen Horowitz, General Catalyst, Blackstone, and others.

I met @___sjones and Sean ten years ago at @PalantirTech.

We always talked about starting a company together, and when we saw how AI would shift the balance of power in security, we had no choice not to.

We started Method to build the tools that American cyber defenders need to achieve real resilience in the face of autonomous threats.

Two years in, we've put together an incredible team of engineers and operators to go after this mission and are deployed with some of the top security teams in the country.

We're grateful to be backed by investors like who believe that American cyber resilience is a challenge worth solving.

We are just getting started.

[Mark Scianna @markscianna]

@method_security out of stealth today and tackling one of the hardest problems in national security.

Cyber offense is scaling to infinity as adversaries weaponize AI into machine-speed attacks. Method Security provides enterprises autonomous systems to counter these persistent threats, built by a founding team from Palantir, Shield AI, NSA, USAF, CrowdStrike, Microsoft, and AWS.

Proud to back @dan__kelly, @___sjones, Sean and team!

[will bitsky @willbitsky]

2013 me was lucky to meet @___sjones as a student at cornell

2025 me was lucky to join the @a16z team that backed his company @method_security

congrats guys, huge day

[Sam Jones @___sjones]

Team and mission.

When trying to build something ambitious from scratch nothing else comes close to mattering as much as those two things.

This mission is very personal to me - we are building the capabilities I wish I had when I started my career as a cyber operator in the US Government.

It is an absolute honor to be doing that as part of this incredible team.

Securing what matters requires us to innovate on both technology and business model. It will not be easy, but this is the team to do it.

Onward.
