Seven months ago, Dan Shiebler and I started Artemis Security. Today, we’re coming out of stealth with $70M in funding. The round was led by Felicis with First Round Capital and Brightmind Partners doubling down, alongside top VCs including Theory Ventures, Lockstep, Two Sigma Ventures, and prominent cybersecurity industry leaders, including the founders of Abnormal AI and Demisto, the former CEO and CTO of Splunk, and senior executives from CrowdStrike, Palo Alto Networks, Microsoft, and Okta. I spent a decade building enterprise security platforms at Demisto, Palo Alto Networks, and AWS GuardDuty. Dan led AI/ML at Abnormal AI and Twitter. Across hundreds of security teams, we kept seeing the same thing: more data than ever, and almost no way to use it to stop attacks. Detections tuned for someone else's environment. Investigations done by hand. Attackers moving faster than any human workflow can match. We built Artemis to change that. Artemis understands your environment before it starts looking for threats - modeling relationships between users, machines, cloud workloads, applications, and business context across every log source. Detections adapt to your environment. Every signal triggers an autonomous investigation that already knows your baseline. You don't get an alert and a link to raw logs. You get a story: what happened, the evidence, what was contained by Artemis, and what needs your judgment. The result: our customers have reduced their mean time to detect and respond to security events by 94%. We're in production with some of the world's largest companies across financial services, technology, and insurance, analyzing over 15,000TB daily. We are grateful for those who believed from the first moment till now and excited for what’s to come. If your security team is spending more time assembling context than making decisions, we'd love to show you what Artemis can do. Want to learn more? Visit https://lnkd.in/ejKq3zik
