With artificial intelligence changing the threat landscape, attackers have started to deploy machine-speed evasion techniques at a scale and sophistication that conventional security operations centers (SecOps) are unable to contend with. Closing the Gap in Detection Engineering Founded to address a glaring inefficiency in modern security operations, Spectrum Security aims to solve the problem of manual detection authoring. According to data from the company’s pilot programs, the manual process of building, testing, and deploying detection logic can take upwards of 121 days on average.

This delay creates massive “coverage blind spots” that attackers exploit long before security teams can mount an effective defense.

The platform uses the infrastructure as an input source, always scanning it for gaps, and intelligently applies advanced threat intelligence, delivering production-ready rules to the environment.

Upon changes to the infrastructure, the platform automatically updates those rules.

In pilot environments, the company demonstrated a reduction in detection authoring time from 121 days to under 30 minutes, a staggering 99% improvement.

Furthermore, these organizations saw a 90% reduction in engineering hours spent on maintenance while achieving 100% health coverage. “Every CISO has had the moment in the breach post-mortem where the answer is a gap nobody mapped, a rule nobody maintained, or drift nobody noticed,” said Meny Har, co-founder and CEO of Spectrum Security. “That’s why we built Spectrum, so security teams stop wondering whether they’re covered and start knowing.” Market Context and Strategic Direction The $19 million raise points to the increased emphasis on “detection as code” and evolution of security engineering.

Cybersecurity funding overall is strong for 2026, with the total sector seeing over $4.6 billion in Q1 funding alone. Investors are more than ever investing in AI-powered platforms providing real automation and not just “visibility” as security teams struggle to keep pace with fast-changing and growing surfaces. Kevin Skapinetz, general partner at TechOperators, noted the unique value proposition of the team, stating, “I’ve spent my career building and operating the detection systems the industry still runs on today… 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.”
