Spectrum Security, a newly launched cybersecurity platform automating threat detection for enterprise security teams, has come out of stealth alongside a $19m seed funding round.
TechOperators led the investment, joined by WhiteRabbit Ventures, Skinos Ventures, a cybersecurity-focused fund created by Shlomo Kramer and Yishay Yovel, Alumni Ventures, and a number of well-known cybersecurity operators and investors.
The capital will be used to expand Spectrum’s engineering team and scale its go-to-market operations to keep pace with enterprise demand.
Spectrum was built to confront a problem the company argues has gone unaddressed for over a decade: organisations investing heavily in security infrastructure still cannot reliably confirm whether they are covered against the threats actively targeting them. That challenge is becoming more acute as attackers harness AI to discover vulnerabilities and launch exploits within hours of disclosure, while detection and response cycles continue to lag behind by weeks.
The platform scans for gaps in threat coverage, produces detection rules tailored to each customer’s environment. It sits on top of whatever stack a customer already uses, including SIEMs, data lakes, and EDRs, with no requirement to replace existing tooling.
Spectrum reports that in production environments it has shrunk detection authoring timelines from 121 days to under 30 minutes, a 99% improvement, while reducing the associated engineering burden by 90%.
Spectrum Security co-founder and CEO Meny Har said, “Every CISO has had the moment. The breach post-mortem where the answer is a gap nobody mapped, a rule nobody maintained, drift nobody noticed. That’s why we built Spectrum, so security teams stop wondering whether they’re covered and start knowing. Continuously, automatically, and at the speed the threat demands.”
TechOperators general partner Kevin Skapinetz said, “I’ve spent my career building and operating the detection systems the industry still runs on today. I know what they were designed for, and I know what they weren’t. They weren’t designed for a world where AI generates working exploits faster than a team can write a single detection rule. Spectrum is building what comes next, and the team assembled around this company is the strongest I’ve ever seen around the detection problem.”
