CISO-Voted List Recognizes the 30 Private Cybersecurity Companies Shaping Enterprise Security in the Age of AI

SAN FRANCISCO, May 12, 2026 /PRNewswire/ — Abstract, the leader in streaming-first security data operations, today announced its inclusion in Rising in Cyber 2026, an independent annual list launched by Notable Capital to recognize the 30 most promising private cybersecurity startups. Now in its third year, Rising in Cyber has become a trusted signal of what is actually moving the needle in enterprise security.

Unlike traditional rankings, Rising in Cyber honorees are selected through voting by 150 active CISOs and senior security executives; the result is a reliable signal of what security teams are actually adopting to address their most urgent challenges.

Abstract joins a cohort that has collectively raised over $6.9 billion, according to PitchBook, and is defining the next generation of cybersecurity across critical areas, including identity and access management, agentic AI security, security operations, and application defense.

The 2026 honorees were named alongside the release of the Rising in Cyber 2026 Report, produced in collaboration with Morgan Stanley. The report draws on CISO survey data and market analysis to map how the cybersecurity industry is evolving from AI agents reshaping security operations to a historic surge in strategic M&A, and separates signal from noise for investors, operators, and security leaders.

“Security is now moving from a constraint to an enabler on how fast AI can actually scale inside the enterprise. The 150 CISOs who voted on this list understand that better than anyone,” said Oren Yunger, Managing Partner, Notable Capital. “Congratulations to this year’s Rising in Cyber honorees for earning their trust.”

Honorees will be recognized at a private event on May 12 at the New York Stock Exchange in San Francisco alongside top security leaders and investors.

“Abstract is honored to be named to the Rising in Cyber 2026 list of the 30 most promising private cybersecurity startups,” said Colby DeRodeff, CEO and co-founder, Abstract. “This recognition from 150 CISOs confirms what we’re hearing in the market: security leaders are done forcing their environments to fit their SIEM, and they’re looking for a platform they can actually build around their existing stack.”

What Abstract’s AI-Gen Composable SIEM Means

AI-Gen Composable SIEM introduces a system-of-systems architecture that enables organizations to:

• Decouple data sources and destinations to eliminate vendor lock-in
• Run detections in-stream for real-time threat response
• Tier and route data intelligently to reduce storage costs
• Embed AI across workflows for triage, investigation, and response
• Scale elastically across multi-cloud and hybrid environments

Unlike legacy platforms that centralize all functionality into a single stack, Composable means  enterprises can choose their architecture, deployment model, and analytics engines without sacrificing performance or control.
