Artemis reels in $70M to make breach remediation more efficient with AI

Six-month-old cybersecurity startup Artemis Global Technologies Inc. today disclosed that it has raised $70 million in funding.

The capital arrived in two tranches. Felicis led the largest of the two transactions, a Series A round, with participation from First Round Capital and Brightmind, the firms that backed Artemis’ seed raise. The company’s investor roster also includes executives at Microsoft Corp., Okta Inc. and other major tech firms.

Artemis sells an artificial intelligence platform that helps enterprises remediate cybersecurity issues. The company positions its software as an alternative to traditional SIEM, or security information and event management, platforms. Those are applications that find threats by analyzing telemetry from a large number of technology assets.

Loading telemetry into a SIEM platform can incur significant data streaming costs. According to Artemis, its platform addresses the challenge with a feature called federated querying. The technology analyzes cybersecurity telemetry in the system where it’s generated, which removes the need to load the data into Artemis.

The platform can analyze telemetry from cloud environments, employee endpoints and a wide range of other systems. It scans the data for threats using detections. Those relatively simple pieces of code that each focus on spotting a specific type of malicious activity. Artemis uses AI to automatically generate detectors and modify them when the threat landscape changes.

When the platform finds a breach, it generates a visual timeline of how the cyberattack unfolded. Artemis could, for example, determine that an attempt to download files from a sensitive database was preceded by a change to a company’s firewall settings. The timeline is displayed alongside a natural language incident description that contains more technical details.

Administrators can bring up additional data about a breach by entering questions into a chat box. A user could, for example, ask Artemis whether similar incidents occurred in the past. The platform also generates remediation suggestions for each breach that it analyzes. For example, Artemis might recommend that administrators block the IP address from which a cyberattack was launched and rotate the passwords of compromised employee accounts. 

“Agentic threat hunting proactively looks for suspicious activities,” Artemis Chief Executive Shachar Hirshberg (pictured, left, with co-founder and Chief technology Officer Dan Shiebler) wrote in a blog post. “Every security signal triggers an autonomous investigation that understands your baseline. You get a full story: here’s what happened, here’s the context, here’s the evidence, here’s what can be contained, here’s what needs your judgment.”

Artemis will use the proceeds from its two funding rounds to hire engineers and go-to-market professionals.
