Nozomi Networks, which aims to shield critical infrastructure from cyberattacks, raises $100M Series D led by Triangle Peak Partners as it prepares for an IPO

Context & Ripple Effects
Nozomi Networks' $100M Series D lands mid-wave in a crowded funding cycle for infrastructure-exposed attack surfaces: just three months earlier Cymulate closed its $45M Series C for simulated-attack testing, CyCognito had raised its Series A for internet-connected device analysis in late 2019, and Cyberpion followed in 2022 with external-asset protection capital.
What separates Nozomi from that cohort is stage and endpoint: the Triangle Peak-led round is explicitly framed as a runway to an IPO, making it the closest thing the corpus has to a public-market benchmark for critical-infrastructure security — a category later entrants like Zero Networks ($55M for ransomware prevention) and Nagomi Security are still building toward from earlier stages.
First-order effects
- Nozomi gains a nine-figure war chest to scale deployments protecting power grids, water systems, and factories — the operational-technology footprint where it specializes — while Triangle Peak Partners takes the lead position with IPO-priced upside on its stake.
- The stated IPO path forces near-term discipline on Nozomi's metrics: revenue quality and growth rates now get audited against public-market expectations rather than private-round narratives.
Second-order effects
- Rivals in adjacent security niches — Cymulate's breach-simulation testing, Cyberpion's outside-facing asset coverage, Zero Networks' ransomware containment — face a better-capitalized competitor positioned to bundle monitoring with broader platform deals for utilities and industrial operators.
- Late-stage investors reading the round will reprice comparable OT-security assets upward, tightening supply of fundable Series B/C companies in the segment as valuations converge toward Nozomi's trajectory.
Third-order effects
- If Nozomi completes its IPO, public-market multiples for critical-infrastructure security become visible for the first time in this cohort, giving later-stage startups like Nagomi Security and Zero Networks a defined exit template rather than acquisition-only paths.
- The pattern points toward consolidation of infrastructure security around a small number of scaled platforms, with venture capital concentrating in fewer, larger checks as the sector shifts from point solutions to system-of-record vendors.
The trend: Venture capital is concentrating into late-stage, IPO-bound rounds for operational-technology and critical-infrastructure security startups as the category matures out of the seed-stage funding cycle that produced Cymulate, CyCognito, and Cyberpion.
