Nagomi Security
Nagomi unifies fragmented security tool data to show CISOs which threats their existing stack actually stops, and where the real gaps are.

Nagomi Security builds a Proactive Defense Platform that ingests telemetry and configuration data from an organization’s existing security tools and maps their real, current coverage against the MITRE ATT&CK framework. Rather than recommending new point products, Nagomi’s premise is that most enterprises already own the tools they need but are not using them to full effect; the platform surfaces misconfigurations, redundant spend, and untested defenses so security teams can close gaps with what they already have.
The company emerged from stealth in April 2024 with $30 million in total funding ($23M Series A led by TCV, plus a previously unannounced $7M seed from Team8), with strategic participation from CrowdStrike Falcon Fund and Okta Ventures and backing from well-known security founders including Shlomo Kramer and Nir Polak. Early traction includes a Fortune 500 customer and over $1 million in ARR shortly after launch.
Nagomi’s differentiator is treating exposure management as a data-unification problem across an organization’s own tool sprawl rather than another standalone detection product, which resonates with CISOs under pressure to prove ROI on existing security spend before buying more tools.
Innovation Matrix Assessment
Rapid move from stealth to a $30M raise, notable strategic investors (CrowdStrike, Okta) and an operating platform mapping coverage to MITRE ATT&CK within its first year.
Directly targets CISO pain of underutilized tool investment; unifying fragmented telemetry into an actionable coverage view has clear day-to-day operational value.
Early but real: Fortune 500 customer and $1M+ ARR shortly after emerging from stealth, plus strategic investment from major security vendors signals credible market interest. Recognized in Cyber Defense Media Group's 2026 Global InfoSec Awards (1 award), independently juried industry validation of market traction.
Exposure/attack-path management is an increasingly crowded category; Nagomi's angle of optimizing existing tools rather than adding new detection is a meaningful but incremental twist, not a category reinvention.
Efficacy claims are still primarily vendor- and investor-sourced; no independent third-party testing or named customer case study was found publicly.
Getting more value out of existing, expensive security stacks will remain a persistent CISO priority as budgets tighten and tool sprawl grows.
Why CISOs Should Care
Helps CISOs prove and improve the effectiveness of tools they already pay for, rather than adding another point product to the stack.
What Makes It Different
Focuses on unifying and scoring existing tool coverage against MITRE ATT&CK rather than shipping new detection or prevention technology.
The Matrix Verdict
68/100 — INCREMENTAL INNOVATOR
A promising, well-capitalized approach to exposure management that is still building the independent evidence base to match its funding and investor pedigree.
Editorial Note: Claims vs. Verified Findings
Growth and efficacy metrics (ARR, customer counts, effectiveness percentages) come from company and investor announcements; no independent audit was located.
