Threat detection startup Spectrum Security has emerged from stealth mode with $19 million in seed funding.
The investment round was led by TechOperators, with additional support from WhiteRabbit Ventures, Skinos Ventures, Alumni Ventures, and various angel investors.
Founded in 2025, San Francisco-based Spectrum is aiming to close the detection gap with a platform that automates detection upstream.
The solution works with existing stacks, SIEM solutions, data lakes, and EDR tools, looking for coverage gaps to fix detection with production-ready logic tailored to the environment.
According to Spectrum, its platform can compress detection authoring and reduce engineering hours while continuously monitoring the environment and fixing detections to ensure full coverage.
The startup will invest the fresh funds in accelerating its engineering and go-to-market efforts.

“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,” said Spectrum co-founder and CEO Meny Har.
