AI-Driven Security Model Addresses Growing Trust Challenges

Daylight provides managed security operations where AI agents handle most routine tasks while human security engineers focus on decisions requiring judgment1

1

. This approach directly addresses a growing challenge in the industry: determining when to trust AI has become a bigger part of security operations. According to a July 2026 ISC2 survey of 856 cybersecurity professionals using AI-native technology, 65% now spend more time determining whether to trust AI recommendations than they did a year earlier, while 63% spend more time verifying AI outputs1

Flexible Deployment Options and the Aura Platform

The company offers three deployment models to fit different organizational needs. Customers can hand over security operations entirely, run them jointly with an internal team, or deploy forward-deployed Daylight engineers alongside their own staff1

. All customers gain access to the Aura platform, which enables security teams to investigate their environment using natural language-based threat investigation or search a centralized data lake that Daylight began offering as a managed service in June1

. This flexible service model addresses a gap in the market where traditional managed security providers offer rigid, one-size-fits-all services while standalone AI tools often leave companies managing yet another system2

Speed and Coverage Extending to AI Systems

Daylight detects cyber threats within seconds and contains them within minutes, up to 10 times faster than traditional managed security providers1

. The company's coverage extends to AI systems that enterprises deploy internally, investigating alerts about prompt injection or risky Model Context Protocol integrations alongside identity, endpoint, and cloud activity1

. Visual collaboration company Miro is already using this capability, joining other customers including AI app builder Lovable Labs, password manager LastPass, financial research startup Rogo Technologies, and emerging-markets payments company dLocal1

Leadership Vision and Expansion Plans

Co-founder and CEO Hagai Shapira, who met co-founder Eldad Rudich while serving in Israel's Unit 8200 intelligence unit, stated that the measure of security operations is shifting from headcount toward "how effectively AI agents can take on increasingly complex security work"1

1

. Both founders previously worked at security automation company Torq Technologies, where Rudich served as the first employee and eventual vice president of research and development1

1

. Irit Kahan, Managing Director and Global Head of Cybersecurity Investing within Growth Equity at Goldman Sachs Alternatives, said pairing human expertise with agentic technology could enable Daylight's customers to respond "at machine speed"1

1

. Daylight plans to use the funds to expand in the U.S. and enter markets across Europe, the Middle East, Africa, and Asia-Pacific while growing its security engineering and technology teams and continuing development of the Aura platform1
