Artemis Security launches Orion-1, an autonomous cyberattack response model

Key points

• Orion-1 links log data from networks, endpoints, cloud and SaaS apps to trace signals back to a single attacker.
• On Artemis's own DGR benchmark, it scored 80.8 on attack reconstruction versus 58.3 for the next-best model.
• Private preview for select customers; high-impact actions require human approval by default.
• Artemis says no customer data was used in training, and it has not said whether Orion-1 builds on another provider's model.

Why it matters for marketers: Comparisons rest on Artemis's own benchmark, which omits Mythos 5 and GPT-6 Astra, so treat its performance claims as unverified until independently tested.
