Artemis Security has made Orion-1 available to selected customers through a private preview of its security platform. The company says the model investigates threats across enterprise systems, produces verdicts with stated confidence and can recommend or execute responses within customer-defined limits.

The platform maps accounts, devices and organizational relationships to provide context for investigations. Response options include revoking sessions, isolating hosts and disabling mailbox rules. High-impact actions require human approval by default. Artemis's reported benchmark comparisons cannot be independently reproduced from its public launch materials.
