Spectrum Breaks Stealth: Close the Detection Gap and End the Guesswork
Detection is the layer everything depends on, and nobody has modernized it. Today we launch Spectrum to change that.
Today marks a massive milestone for our team. After building quietly behind the scenes, I'm excited to finally share what we've been working on at Spectrum - and why we believe this is the most important unsolved problem in cybersecurity.
The Problem Has Been Hiding in Plain Sight
For over a decade, the industry has focused on scaling data collection. Organizations expanded log pipelines, centralized telemetry, and deployed additional sensors to increase visibility. The spend keeps going up - more SIEMs, more data lakes, more headcount, more red team engagements.
But increased visibility hasn't translated into better detection.
I've spoken with countless security leaders who share this reality. They cannot confidently demonstrate that their detections actually cover the threats actively targeting their environment - and they have no way to measure the return on the massive amount they're spending to get there. Figuring out what needs to be detected is a massive, constantly moving challenge on its own. Actually building those detections is manual and slow. Maintaining them is worse - rules break silently as infrastructure shifts, log schemas change, and attacker techniques evolve. The backlog never shrinks. It compounds.
We call this the Detection Gap. And it's getting worse.
AI Changed the Math on Every Side
As organizations embrace AI across the business, their environments are becoming more dynamic than ever. The attack surface is reshaping faster than security teams can track. The underlying data is shifting. What was already hard to keep up with is now moving at a pace that manual processes simply cannot match.
On the other side, AI-driven adversaries can now take a published advisory, generate a working exploit, and launch a campaign in hours - a cycle that used to take weeks. The iteration loop is compressing every day.
Detection? Still measured in weeks. That gap is rapidly widening. What could barely work at human speed before is now fundamentally broken.
Why We Built Spectrum
We've been in that room. The breach post-mortem. The red team debrief. The moment someone asks "how did we miss this?" and the answer is usually a gap nobody mapped, a rule nobody maintained, drift nobody noticed. Every security leader knows that moment.
That's why we built Spectrum - so security teams stop wondering whether they're covered and start knowing.
Instead of layering on more tools downstream, we went after the root cause. Spectrum works across the full detection lifecycle:
- Map Coverage - Spectrum continuously monitors your threat coverage against real-world threats, your internal findings, and the realities of your environment. Always know what you're detecting - and what you're not.
- Build Detections - For every gap identified, Spectrum builds deep environmental intelligence to determine what needs to be detected, where, and from which data. It then authors production-grade detections tailored to your stack. From gap to deployed detection in minutes, not months.
- Stay Resilient - Once deployed, Spectrum continuously monitors detections, identifies drift, keeps them current with evolving attacker behaviors, and optimizes them over time. Catch drift. Fix breakage. Stay covered.
It layers on top of whatever you're already running - your SIEM, your data lake, your EDR. Nothing gets ripped out. Your team drives the priorities and validates what goes to production. Spectrum handles the rest.
What We're Seeing in Customer Environments
The results have been striking. What used to take teams over four months to research, author, and deploy now happens in under 30 minutes. Engineering hours have dropped by 90%. And because Spectrum continuously monitors and fixes detections, customers are maintaining full coverage health for the first time - not as a snapshot, but as a constant.
Better coverage. Less waste. Less engineering burn. A security operation that can confidently respond to what matters, even as threats accelerate.
The Right People at the Right Time
We're backed by $19M in seed funding led by TechOperators, with participation from WhiteRabbit Ventures, Skinos Ventures (a new cybersecurity fund backed by Shlomo Kramer and Yishay Yovel), and Alumni Ventures. These aren't traditional investors - they're operators who have built, run, and scaled the security platforms the industry relies on today. They've lived this problem from every angle and they believe, as we do, that it's finally solvable.
I also want to thank our team. Building something that fundamentally shifts the equation for security operations takes more than ambition - it takes people at the forefront of AI research, engineering, and detection engineering working side by side. The talent, conviction, and relentless execution this team brings every day is what makes Spectrum real.
The Detection Gap Ends Here
To the security leaders and practitioners on the front lines: the gap between how fast threats move and how slowly detection keeps up isn't closing on its own. Everything downstream - triage, investigation, response - inherits that failure. If the foundation is broken, nothing built on top of it works.
We built Spectrum to fix the foundation. Continuously, automatically, and at the speed threats demand.
We're just getting started. I'd love to show you what Spectrum can do in your environment.
