Company profile
researched Aug 2026Vega is a cybersecurity company founded in 2024 that sells what it calls an Agentic Cyber Defense Platform, built on a component it names the Security Analytics Mesh (SAM). The core architectural premise is that security data does not need to be centralized before it can be used for threat detection: Vega runs detection, hunting, assessment, investigation and triage against data where it already resides, including cloud services, data lakes and existing object storage across the three major cloud providers, without migration, ingestion or parsing.
The platform allows users to query datasets in natural language, in KQL, or through Vega's MCP interface, normalizing sources as if they shared a single OCSF schema and presenting results in multi-cell notebooks. Product areas marketed on the company site include Agentic Hunting, Detection Skills (which encode analyst triage, investigation and tuning judgment), Agentic Detection (plain-language detection authoring with query drafting, enrichment planning and MITRE mapping), Agentic Triage (alerts pre-triaged and correlated into decision-ready cases with verdict, evidence and reasoning), and Headless Cyber Defense, which exposes the platform as tools callable by any AI client over MCP. Vega also states its platform helps map and remediate coverage gaps and noisy detection rules, and that AI capability is limited by the data it can access — the limitation it says the legacy SIEM centralization model imposes.
Founding story
Co-founder and CEO Shay Sandler served in the Israeli military's cyberwarfare Unit 8200 and was one of the founding employees of Granulate, an application performance optimization firm acquired by Intel for $650 million in 2022. After a year at Intel he set out to build in cybersecurity. Co-founder and CTO Eli Rozen is likewise a veteran of Unit 8200 and a former Granulate employee. The company describes its leadership as having encountered the limits of legacy SIEM on the front lines of cyber defense and founding Vega in 2024 to move past them.
Business model
Vega sells an enterprise software platform to security organizations, with reported multimillion-dollar contracts with large enterprises. The company positions its commercial pitch around eliminating legacy SIEM costs, stating there are no ingestion fees, no duplicate storage and no migration projects, and claiming up to 82% lower cost than legacy SIEM.
Sources describe multimillion-dollar enterprise contracts but do not specify pricing structure beyond the claim that the platform carries no ingestion fees or duplicate-storage costs.
Traction
The company reports over 100 employees (Built In NYC lists 134 total employees and 8 posted jobs; the Vega site lists 16 open roles), multimillion-dollar contracts with banks, healthcare companies and Fortune 500/Fortune 200 firms including Instacart, and $185 million raised in under two years at a $700 million valuation. Published customer testimonials come from Peloton's Deputy CISO and an engineer at a top-four US bank.
Latest developments
On 10 February 2026, Vega announced a $120 million Series B led by Accel with participation from Cyberstarts, Redpoint and CRV, at a $700 million valuation and $185 million in total funding, to be used for further development of its AI-native security operations suite, go-to-market expansion, and global expansion.

Market position
Vega competes in the security analytics and SIEM replacement market, which sources describe as dominated by Splunk (acquired by Cisco in 2024 for $28 billion). Vega positions itself in a "post-SIEM" category and claims to be the world's first Agentic Cyber Defense Platform. It reports signing multimillion-dollar contracts with global banks, healthcare organizations and Fortune 500/Fortune 200 companies, including Instacart, and at least one customer says it fully replaced its legacy SIEM.
Vega's stated differentiator is running analytics and detection in place rather than requiring data centralization, which it argues avoids ingestion and duplicate-storage costs and multi-year migration projects while preserving full visibility. Accel partner Andrei Brasoveanu framed the contrast with incumbents by saying that Splunk and subsequent contenders have always centralized data, which holds customers hostage. Vega also emphasizes an integrated agentic loop — analytics, assessment, detection and triage in one product rather than a single automated workflow — and headless operation via MCP.
Technology
The platform is built on the Security Analytics Mesh (SAM), which provides universal querying across disparate data sources — including low-cost object storage across the three major clouds — treating them as if they shared a single location and OCSF schema, with no data migration, ingestion or parsing. Query interfaces include natural language, KQL and MCP; results are assembled in rerunnable multi-cell notebooks. Agentic components handle hunting, detection authoring with MITRE mapping and enrichment planning, encoded "Detection Skills" for triage and tuning, and automated pre-triage and correlation of alerts into cases with attached verdicts, evidence and reasoning. The whole platform is exposed as tools to external AI clients over a single scoped MCP endpoint.
Go-to-market
Vega markets directly to enterprise security operations, detection engineering and SOC teams via demo requests on its website, and is building out sales coverage with regional sales manager and sales engineer roles across US territories plus technical account management. It cites customer references including a Deputy CISO at Peloton and a principal cyber defense engineer at a top-four US bank, and says Series B funding will be used to strengthen its go-to-market team.
Enterprise security operations centers, detection engineering teams and cyber defense engineers, including global banks, healthcare organizations, Fortune 500/Fortune 200 companies and cloud-heavy enterprises.
Geography
Sources describe Vega as an Israeli cybersecurity startup, while Built In NYC lists its headquarters as New York, New York, USA, with a hybrid workspace and remote US-based sales and technical roles. The company said it would use Series B proceeds in part to expand globally.
History
Vega was founded in 2024 by Shay Sandler (CEO) and Eli Rozen (CTO). It emerged from stealth in September 2025 and raised a $120 million Series B announced on 10 February 2026, led by existing investor Accel with participation from Cyberstarts, Redpoint and CRV. That round nearly doubled the company's valuation to $700 million and brought total funding to $185 million in under two years. By the time of the round the company had scaled to roughly 100 employees.
Risks & controversies
No controversies are reported in the available sources. Sources note the general difficulty of displacing entrenched incumbent SIEM budgets, with the CEO acknowledging that enterprises often find it easier to criticize the status quo than to switch; performance, cost and efficacy figures on the company website are vendor claims that are not independently verified in the sources.
