At the end of its first year, this AI native platform, which is oriented towards secure operations, had launched five products, raised 70 million US dollars within six months, and was selected for Fortune's Cyber 60 list for 2026–2027.

New York, October 29, 2026 / PRNewswire / -- AI native platform, focused on secure operations, announced today the appointment of Arun Singh as Chief Growth Officer (CGO). A day before this announcement, Artemis was just selected for Fortune's Cyber 60 list for 2026–27; at the same time, the company also concluded its first year of operation. The company stated that during this year, its revenue grew by more than 100 times, and its customer base expanded from some of the largest corporations in the world to AI native startups.

Artemis, Co-Founder and CEO, Shachar Hirshberg stated: "From Fortune 500 companies to AI native startups, Artemis has proven that defenders can stop attacks at AI speed. Unlike most security operations where AI typically only starts working after an alarm is triggered, Artemis learns each customer's environment, continuously maintains a dynamic model of that environment, and writes and optimizes detection mechanisms for each customer. Based on the same model, it can also perform threat hunting, investigate each case, and respond accordingly. In our first year, it marked 92% of confirmed attacks at the entry point within seconds. Arun has previously expanded products that defined categories in large markets. He is the right person to lead us into the next phase of growth."

The company stated that as the Chief Growth Officer, Singh will lead Artemis into the next phase of growth. He possesses expertise in cybersecurity and enterprise software from Salesforce, Okta, Cloudflare, Abnormal AI, and Drata. Recently, while serving as the Chief Marketing Officer at Drata, he helped define the "Trust Management" category and facilitated the company's transformation from a compliance automation tool provider to a strategic enterprise platform. Prior to that, he was responsible for marketing at Abnormal AI, where the company's annual recurring revenue (ARR) grew by more than 12 times over three years, and it was recognized as a market leader by Gartner and Forrester.

Singh indicates that "attackers are now acting at a speed of AI, while security operations still operate at human speed. Artemis aims to bridge this gap by leveraging the defender's only sustainable advantage at the moment of detection – their understanding of their own environment. It is rare in my career to see companies adopting such speed, and my current focus is on building on this momentum. I look forward to bringing Artemis to more security teams."

Narrow the gap between attackers and defenders

The company stated that over the past 20 years, SIEM has always been at the core of secure operations. It was initially built to search logs when analysts had response times of several hours or days. Today, the speed at which attacks driven by AI are moving is faster than any security team can catch up with through recruitment, and faster search engines are of no help when analysts still need to manually piece together each piece of evidence.

Artemis indicates that a different approach was adopted. It builds a dynamic model for each organization and uses this model to continuously perform detection, threat hunting, and investigations. By the time each case is presented, the investigation is already complete, along with response actions that can be approved by analysts; with customer permission, these actions can also be executed automatically. The company claims that the performance of Artemis in its first year shows that the AI native platform can replace traditional security operations technology stacks in demanding enterprise production environments.

The company states that its key differentiating capabilities include:

• Environmental Intelligence ( Environment Intelligence ):Artemis models each user, account, device, resource, and AI proxy, and utilizes systems that already understand how the organization operates, including human resources, identity management, cloud, and asset inventory systems. Detection processes are run based on this model, and adaptive detectors are written and automatically tuned for each environment. As a result, Artemis is capable of capturing attacks that never trigger any rules in traditional SIEM.
• Decisions at the decision-making level that are governed by customer autonomy:Each case comes with a plain English summary, the conclusions of Artemis, a complete record of the investigation and conclusions of AI, as well as immediately actionable response measures. The architecture of Artemis supports automatic containment of attacks, and each client can choose which actions to run automatically and which actions require one-click approval from an analyst before execution.
• Ultra-fast pace of innovation:Artemis indicates that functional requests made by customers can be implemented within 48 hours after submission. Within one year, the company has launched five major products, over 8,000 features, more than 38,000 detectors, and completed 30,000 pull requests ( pull request ).
