This is a true story, and Kumo is a real dog.
About a month ago, Iain, CISO at a leading healthcare organization, was out walking Kumo when his Garmin started buzzing. His Corma workforce had caught an attack in progress.
When he opened Teams, the full analysis was already there. Malware beaconing to a C2 had stolen a user's browser cookies, giving the attacker live sessions that got around the password and MFA.
The Corma workforce had traced the attack to the sender and identified every affected host and user. It proposed a response across endpoint, identity and email - quarantine the hosts, revoke all active sessions, force password resets, and block the sender and purge the emails.
Corma coordinated everything with the relevant IT and security personnel, while it was waiting for Iain to approve.
Iain approved it from his phone and started rushing home, much to Kumo's dismay. About 60 seconds and a lot of dog-pulling later, the attack was contained.
Kumo got the rest of his walk.
Frontier AI means attackers never take a break now. Having frontier intelligence for cyber defense means your team still gets to.

When identical copies of a frontier AI model are assigned first as attacker, then as defender on the same enterprise network, the defender fails to find its own attack 78% of the time.
Across hundreds of engagements on a live enterprise network, our new research found that AI attackers established persistent backdoors in 85% of runs, while AI defenders detected only 19% of attacks on average. This held consistent across frontier model providers, including OpenAI and Anthropic.
The reason is structural. Offense rides on everything these models are optimized for: deep understanding of code and systems, finding bugs - and a vulnerability is just another kind of bug - and agentic tool use. Defense lives in logs, events, and telemetry. It demands finding a single malicious signal hidden among millions of normal ones, extreme consistency across thousands of decisions in sequence, and a kind of reasoning that general-purpose training does little to build. Increasingly capable general models just widen the gap - they don't close it.
Full research below 馃憞

Today we are announcing Corma, and our $60M seed round led by @sequoia.
@CormaAI is building foundation models toward superintelligence for defensive cybersecurity. We do that because general AI is becoming exponentially more capable in offensive security, while it hasn't been able to improve at the same rate in cyber defense - creating an inherent imbalance between attackers and defenders that otherwise cannot be addressed.
Recent events have shown that building frontier AI models for defensive cybersecurity is one of the crucial unsolved problems of the AI age - and solving it is the generational mission Corma was founded on.
Our foundation model has already far surpassed every general-purpose frontier model on defensive cybersecurity tasks, and we are committed to remaining the frontier of defensive cybersecurity intelligence.
Corma is already protecting Fortune 100 companies and some of the world's most important organizations, across healthcare, finance, critical infrastructure, retail, and more. This is just the beginning, as we see it as our calling to protect every organization in the world that needs frontier defense.
We are grateful to our partners @shaunmmaguire and @sonyatweetybird at @sequoia , @vkhosla at @khoslaventures , @DanRose999 at @coatuemgmt , and @Weiner_Lia at Netz Capital, who believed in our ability to lead the intelligence race in cybersecurity and make sure the defenders always win.

From secret message boards
To cancelling gym appointments
To jailbreaking onto the open internet
If the last few weeks taught us anything, it's that security is the next frontier of AI
@CormaAI is on the bleeding edge here, and it's finally out of stealth
You will hear A LOT MORE from this company... they've had some major wins over the last quarter
@sequoia is thrilled to lead this round, following @vkhosla who got there before us!
Working w/ my partners @sonyatweetybird, @jamesfly and @carl_eschenbach

We led @CormaAI's seed, following @vkhosla who saw its potential before us (and led the pre-seed)
@AlonPluda is a generational cyber talent -- I'm not saying this lightly -- and we're already seeing this play out with customers
Also, as a total aside, it has been fun to team w/ my partner @sonyatweetybird!
Two years ago we disagreed on almost everything and now we have a mind meld 馃ぃ
