Spectrum Security, a cybersecurity firm specialising in automated threat detection, has emerged from stealth after securing $19m in seed funding.
The round was led by TechOperators, with additional backing from WhiteRabbit Ventures, Skinos Ventures, a new cybersecurity fund established by Shlomo Kramer and Yishay Yovel, and Alumni Ventures, as well as a number of prominent cybersecurity operators and investors.
Proceeds from the raise will be directed towards accelerating Spectrum’s engineering capabilities and go-to-market efforts to address growing enterprise demand.
The company was founded to tackle what it describes as a critical but long-overlooked gap in modern security operations: the inability of organisations to reliably detect threats targeting them in real time.
As AI continues to reshape the threat landscape, attackers are now able to identify vulnerabilities, produce working exploits, and move from vulnerability disclosure to active attack within hours, while detection and response timescales continue to be measured in weeks.
Spectrum’s platform addresses this by automating the process of building, testing, deploying, and maintaining detection logic. Rather than layering on top of existing alert systems, the company targets the underlying problem, identifying gaps in threat coverage, generating production-ready detection rules tailored to individual environments, and updating those rules as infrastructure evolves.
The platform is designed to integrate with a customer’s existing security stack, including SIEMs, data lakes, and EDRs, without requiring any replacement of current tooling.
In live customer environments, Spectrum says it has reduced detection authoring time from 121 days to under 30 minutes, a reduction of 99%, while cutting engineering hours by 90% and maintaining continuous coverage health monitoring.
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.”
