Profile introduction
Artemis helps security teams at Cursor, Wix, Mercury, F500 banks, and more, to detect and stop attacks at machine speed. I spent the past 15 years in the forefront of cyber technology building and leading the products that defined the last decade of cyber defense like AWS GuardDuty, Demisto, and Cortex XSOAR. Love security and helping customers have more good than bad days at work. Previously led product management for AWS GuardDuty where I built the cloud XDR for AWS and scaled it to 100,000 customers. I was an early employee and an engineering and product leader at Demisto and Palo Alto…

Insights & ideas
Hirshberg argues that cybersecurity has entered an "AI vs AI" era, with attackers increasingly using AI-driven techniques, which he believes requires defenders to move beyond traditional, human-dependent SIEM tools toward autonomous, AI-native detection and investigation [1]. He and co-founder Dan Shiebler position Artemis as a response to this shift, built specifically to replace legacy SIEM systems rather than augment them [1]. The rapid funding and stealth exit of Artemis, discussed in the conversation, reflects his conviction that the pace of AI-enabled threats demands a fundamentally new security architecture rather than incremental improvements to existing platforms [1].
