About Artemis
Artemis is a cybersecurity firm developing what it describes as the world's first AI-native protection layer to help organizations defend against increasingly sophisticated AI-driven cyber threats. The company was founded in 2025 by Shachar Hirshberg (CEO) and Dan Shiebler (CTO) and is headquartered in New York, NY.
The founders bring significant experience from prominent technology and cybersecurity companies. Hirshberg previously worked at Palo Alto Networks, AWS, and Demisto, while Shiebler's background includes roles at Abnormal Security and Twitter. Their combined expertise in building and scaling cybersecurity products informs Artemis's mission. The company operates in a market where both attackers and defenders are leveraging artificial intelligence, creating a dynamic and escalating threat landscape.
Artemis's core offering is a platform that acts as an intelligent assistant for cyber defense operations, enabling security analysts and forensic personnel to use natural language for analytics on endpoint data. The system is designed to provide early warnings of digital risks, track threat actors across platforms, and offer actionable insights for mitigation before threats escalate. It aims to streamline security workflows by automating repetitive tasks and providing context that is often missing from standard security alerts. The platform integrates with existing security cameras and systems, using behavioral intelligence to detect unusual activity and send real-time alerts. Artemis is backed by investors including First Round Capital and Brightmind.
