early access insights, threat research, and the latest on autonomous security.
SEP2 runs a 24/7 MDR service across more than 70 customers, from AI-native startups to legacy public sector estates. By automating detection engineering with Spectrum during its build phase, SEP2 cut rapid-response rule deployment time by 66% and doubled its deployed detections with no additional headcount.

Nearly 3 in 10 deployed detection rules are broken. We verified detection estates across six SIEM platforms against customers' live systems — not exported rule files — and replayed the broken ones to count the alerts nobody ever saw.
Our end-to-end agentic research pipeline is generally available: Spectrum continuously researches the threats that can actually reach your environment, and turns that research into detection-ready findings.

Security leaders sound off on AI adoption in detection
Detection logic is cheap; detection knowledge isn't. Delta Tradecraft is an open standard for capturing the research behind a detection so it's reusable.

Meet Delta, Spectrum Security's research team: a skunkworks for autonomous detection engineering and AI threat hunting, publishing its work in the open.
An AI broke out of an OpenAI benchmark and breached Hugging Face with attacks no signature could match. How it was detected holds a lesson for every CISO.
Detection is the layer everything depends on, and nobody has modernized it. Today we launch Spectrum to change that.

Led by TechOperators alongside WhiteRabbit Ventures, Skinos Ventures (by Shlomo Kramer), and Alumni Ventures, Spectrum automates threat detection at machine speed.
Data collection is not detection. After a decade of hoarding logs and relying on manual engineering, security teams are still guessing at their coverage. We are building the future of detection to replace uncertainty with proof
Why traditional detection models fail to keep up with dynamic threats and how AI-driven continuous detection engineering is closing the coverage gap
Visibility is not coverage. After decades of manual engineering and 'heroic' efforts, the pieces are finally in place to solve the detection gap. Introducing Spectrum.
