Vega Arms Defenders with the First Purpose-Built Model Trained for Agentic Cyber Defense

Vega, the pioneer of Agentic Cyber Defense, today introduced Vega II, the next generation of its platform and its most important release since emerging from stealth.

New York, United States, October 1, 2026 -- The next generation of the Vega platform unites a fast, specialized AI model, agentic memory, and seamless access to all data in one undeniable harness for cyber defense.

Vega, the pioneer of Agentic Cyber Defense, today introduced Vega II, the next generation of its platform and its most important release since emerging from stealth. Vega II brings the industry’s first model trained for Cyber Defense to the fight, gives the Agentic SOC a memory that outlasts every ticket, and tears down the legacy SIEM and pipeline barriers that kept data out of reach.

With Vega II, every security team has the harness for cyber defense: the system where AI runs detection, triage, and investigation as an autonomous loop, directed by the judgment of their best defenders, and spanning every source they were forced to keep out of the SIEM.

“AI gave attackers a head start. It doesn’t have to give them the future,” said Shay Sandler, co-founder and CEO of Vega. “Two years ago, we founded Vega on one conviction: the SOC has a new operator, AI agents, and they need all your data, the knowledge and judgment of your best defenders, and a proprietary, open-weight model built for agentic cyber defense. With Vega II, every team finally has the harness, the model, and the speed required to win the fight.”

Why Now

Adversaries adopt frontier models the week they ship. Defenders answer with reasoning never tuned for cyber defense, facts lost when the case closes, and data held behind connectors and pipeline projects. And generic AI is slow: it reasons from scratch on every alert while attackers keep moving. Break the barriers keeping frontier AI from becoming extraordinary cyber defense, and the next era belongs to the defenders.

The Harness and the Model, Built for the Fight

Agentic Cyber Defense demands a purpose-built model, lasting memory of the environment, and access to all data wherever it is stored. With Vega II, teams can:

• Bring the best AI reasoning to the fight: Vega’s first proprietary, open-weight model runs beside frontier intelligence in the platform. Built for speed: it reaches the verdict while generic AI is still thinking, so every alert gets an expert’s read at a scale no team can staff.
• Make every lesson last: Vega Memory captures the environment’s ground truth and actions taken, so each verdict starts from what the team already knows. Engineers inspect, trace, and control what gets saved.
• Access all data: Vega Gateway streams any source into low-cost object storage over OpenTelemetry, webhook, or API, without complex pipelines or legacy connectors. It extends Vega’s in-place analytics to the sources with nowhere to live, onboarded in minutes, so investigations follow attackers where the SIEM never looked.

Supporting quotes:

“The Post-SIEM Era is here, and you can’t wait until something happens to make the switch. It has to happen now,” said Conor Quinlan, member of technical staff, security, at Profound. “Profound is growing about as fast as a company can, and our security program has to keep up. Alerts can no longer be siloed. All of detection and response must live in one platform for the agentic SOC to work. I’ve built world-class Cyber Defense operations twice with Vega at the center, and Vega II is exactly where security operations needs to go.”

"Every AI SOC vendor can triage an alert in a demo. The constraint CISOs keep describing to us sits underneath: whether the agent can reach the evidence where it already lives, whether it carries context from one case to the next, and what continuous inference costs at scale," said Francis Odum, founder and CEO of Software Analyst Cyber Research. "Vega built its architecture around those questions rather than around ingestion-based pricing, and Vega II is the clearest statement yet of the power this approach holds."
