Sequoia Capital Leads Seed Round in Corma to Close the AI Cybersecurity Defense Gap
Sequoia Capital has led the seed round for Corma, a cybersecurity startup building a specialized foundation model and agentic security workforce designed to counter increasingly autonomous and scalable AI-driven offensive attacks.
Frontier AI models favor attackers, who exploit technical vulnerabilities and social engineering, while defenders struggle with out-of-distribution log, event, trace, and telemetry data.
Corma's red/blue testing revealed that an identical model acting as a defender failed to identify a hidden backdoor planted by the attacker 78% of the time.
Led by founder and CEO Alon Pluda, Corma uses large-scale reinforcement learning and self-play across simulated enterprise network environments to train defense-focused agents.
Corma's deployed Security Workforce is currently used in Fortune 500 companies across healthcare, finance, critical infrastructure, and retail, executing end-to-end incident response.
The Defensive Gap in Frontier AI
The emergence of agentic AI and advanced models like Anthropic's Mythos has tipped the cybersecurity balance toward offense, reducing social engineering costs to near zero and enabling rapid zero-day discovery. Conversely, defense relies on open-ended anomaly detection across unstructured logs, traces, and telemetry—data modalities largely absent in general LLM pretraining. In Corma's simulations, defenders failed to detect planted backdoors 78% of the time, even when using an identical model to the attacker.
Corma's Reinforcement Learning Approach
Treating cybersecurity as a zero-sum, two-player game similar to chess or Go, Corma applies reinforcement learning and self-play within simulated enterprise environments that mirror real-world network noise, tools, and telemetry. This vertical integration allows Corma to achieve superior defensive capabilities over general frontier models at lower per-token inference costs, while owning its model weights to avoid third-party usage restrictions.
Deployment and Enterprise Impact
Corma productizes its foundation model as an agentic Security Workforce operating across enterprise tools in operations, identity, cloud, and network security. In one deployment, an agent alerted a CISO via a Garmin watch and contained a pending attack after a single confirmation. In another, Corma identified, contained, and remediated an active campaign within its first hour of deployment after the customer's internal security team had missed it for 52 days.
Cybersecurity is a perpetual fight between the good guys and the bad. The age of agentic AI and Mythos-class models has tipped the scales in favor of the bad guys, opening a Pandora’s box for offensive capabilities. An explosion in CVEs has since
ensued
.
Cyberattacks are about technical exploitation, which requires coding and reasoning prowess. Anthropic’s Mythos can discover and exploit zero-day vulnerabilities. Any model paired with a harness brings the cost of social engineering attacks down to near zero, unleashing them at unprecedented scale. The danger is heightened with every new model release.
Defensive security isn’t improving in parallel. The relevant data lives in logs, events, traces and telemetry, a fundamentally different modality than the bodies of text LLMs usually train on, which barely show up in pretraining. Unlike offensive cybersecurity, which involves goal-directed reasoning towards a defined objective, defense requires open-ended reasoning, continually finding anomalies across vast amounts of normal-looking activity, a distinct capability that typically demands extensive domain-specific training. In short, defense is out of distribution for general-purpose frontier models: neither the data nor the intuition it requires is well-represented in training. In the race toward AGI, we cannot expect the frontier labs to take the detour of overhauling their training pipelines for defensive cybersecurity. And we certainly can’t afford to bet our security on a hope that they do.
Corma has illustrated this “defense gap” in
testing
. They ran red/blue team simulations where an attacker plants a hidden backdoor and a defender tries to find it. The defender failed to find the backdoor 78% of the time, even when the defender was an identical copy of the very same model that planted it. Holding model quality constant, attackers will always have an advantage.
The only answer to scaling laws on offense is better scaling laws on defense. Recent events have shown that frontier AI for defensive cybersecurity is one of the crucial unsolved problems of the AI age. Solving it is the generational mission Corma was founded on.
Corma founder and CEO Alon Pluda and his team are training a foundation model to power defensive cybersecurity agents. Cybersecurity, like Go or chess, is a two-player, zero-sum game with a clean reward (were you breached or not?) and an endless supply of games to play. Reinforcement learning and self-play have produced superhuman results before in this kind of paradigm. We are seeing history repeat itself. Corma pushes this further with large-scale reinforcement learning across cybersecurity environments that replicate real enterprise networks, with all their tools, telemetry and noise – as part of a training pipeline that produces frontier defensive capabilities, outperforming general-purpose foundation models, with much lower per-token inference costs.
In the cat-and-mouse game of cybersecurity, we believe Corma’s vertical integration and “sovereign AI” approach will win. Cost matters (always-on inference costs can rack up quickly). Owning the model weights matters (they aren’t subject to restrictions on cybersecurity-related usage set by the closed model labs). And specialization and inference speed
really
matter (fastest to protect against a new threat wins).
Corma’s foundation model is deployed and productized as an agentic Security Workforce. These workers operate across different security tools and take on roles spanning the entire security organization: from security operations and identity management to cloud and network security and beyond. They are on the job at Fortune 500 companies and large enterprises across healthcare, finance, critical infrastructure, retail and more.
Corma’s foundation model powers agents that complete defensive work end to end. We spoke to one CISO whose Corma agent notified him of a pending attack through his Garmin watch while he was on a walk with his dog in the evening; with one confirmation, the agent was able to shut the attacker down, all while he was still walking. In another instance, within its first hour on the job, Corma uncovered, contained and remediated an active attacker campaign inside a customer’s network that their security team had missed for 52 days.
Training frontier foundation models for defensive cybersecurity requires world-class hackers and world-class researchers – almost no company on earth has both. Alon is personally one of the most elite hackers in the world, and has assembled a cohesive and interdisciplinary team of hackers and researchers that is hill-climbing on technical challenges and building impressive commercial momentum.
We are thrilled to lead Corma’s seed round and to be their partner as they chart new territory in what is sure to be one of the most dynamic races in AI.
