Exclusive: CrowdStrike's CTO is leaving to launch an AI-cyber fund. CrowdStrike global CTO Elia Zaitsev is leaving the cybersecurity giant to launch Cognition, a new venture firm targeting a $170 million fund. Why it matters: AI is creating new attack surfaces, and Cognition is betting the shift will produce a category-defining cybersecurity platform it can find and fund early. State of play: Zaitsev is leaving CrowdStrike after 13 years to launch Cognition alongside Gur Talpaz and Tayler Sipperly. * Talpaz and Sipperly worked in corporate development at CrowdStrike before launching their own early-stage fund, Brightmind. * There, they helped architect what they said was the largest Series A exit in cyber history: SGNL, which they entered at $105 million and exited at $740 million. * They see Zaitsev as their new fund's "superpower," Sipperly said, adding that "being able to offer" his expertise to founders is "deeply unique in the market." Between the lines: Cognition's thesis is that agentic AI is a platform-reset moment for cyber. * The three former CrowdStrikers behind the fund are specifically hunting for the rare technical team capable of building the next broad security platform. * Cognition plans to lead or co-lead seed and Series A rounds, and expects to make three or four concentrated investments a year. * Its model calls for average checks of $6 million at seed and $15 million at Series A. What they're saying: "We have this new attack surface that's being brought on by AI and agents," Zaitsev told Axios. * Zaitsev and his cofounders are looking for teams that can "keep up with the constantly changing adversarial threat landscape." * "AI security didn't exist five years ago... But as the adoption of AI dramatically ramps up in the enterprise, it requires a new set of tools," Talpaz told Axios. The bottom line: Cognition is betting AI will make cybersecurity harder to address and much more valuable.

Summary. Cullinan Holdings, a leading tourism group in South Africa, faced challenges in securing customer information and ensuring platform availability amidst evolving cyber threats. By adopting the AI-native CrowdStrike Falcon(R) platform, they significantly improved their security operations, reducing security alerts by 65% and enabling their IT team to focus on genuine risks. Background. Cullinan Holdings operates in the tourism industry, managing over 20 businesses and employing around 1,000 staff. Before deploying CrowdStrike, the company struggled with multiple security tools that created blind spots and uncertainty in their security environment, impacting their ability to protect customer information effectively. Challenge. The primary challenge was the lack of confidence in the existing security measures, which resulted in significant blind spots and an overwhelming number of alerts that required extensive investigation. This inefficiency hindered the IT team's ability to respond to real threats promptly. Solution. In 2024, Cullinan implemented the CrowdStrike Falcon(R) platform, starting with Falcon(R) Insight XDR and Falcon(R) Adversary OverWatch. During the proof of concept, the platform identified critical security gaps, such as outdated operating systems and dormant malware. Within four weeks, the Falcon platform was deployed across all 1,000 endpoints, allowing Cullinan to refine detections and strengthen security policies. Results. The deployment of the Falcon platform led to a 65% reduction in security alerts, enabling the IT team to prioritize genuine threats. This shift allowed team members to focus on strategic initiatives rather than chasing false positives, enhancing overall operational efficiency. Key insights. Organizations should prioritize a unified security strategy that integrates various tools to improve visibility and reduce operational noise. A proactive approach to cybersecurity, akin to a comprehensive home security system, can significantly enhance resilience against threats. Customer testimonial. "CrowdStrike wasn't just the right choice for Cullinan. It was the only choice. We couldn't find anything that could compete. Once we started using the Falcon platform, we realized just how much we'd gained in securing our environment, reducing noise, and making sense of the alerts we were receiving." - Ryan Porter, CIO, Cullinan Holdings Entities mentioned.
