Dragos, which helps secure control systems for critical infrastructure, raises a $200M Series D at a $1.7B valuation led by Koch Disruptive Tech and BlackRock

Context & Ripple Effects
Dragos is doubling down on operational-technology security just over a year after its $110M Series C for protecting power plants and similar industrial systems — and the new money comes from an unusual pairing: Koch Disruptive Tech, which had already backed chip-reliability monitor ProteanTecs, and BlackRock, an asset manager with direct exposure to the infrastructure it protects.
The round reads differently in hindsight: Dragos went on to anchor Accenture's $4.18B acquisition package alongside runZero and NetRise, making this 2021 raise the last big independent step before the specialist was absorbed into a consulting giant's portfolio.
First-order effects
- Dragos gains $200M to scale deployments across utilities and industrial operators, with its valuation nearly doubling from the Series C level implied by prior coverage.
- Koch Disruptive Tech and BlackRock each take a direct stake in securing the physical systems their own businesses depend on — energy assets for one, financed infrastructure for the other.
Second-order effects
- Rivals in industrial control-system security now compete against a company whose cap table includes the asset managers financing the very infrastructure being defended, raising the bar for follow-on rounds across the category.
- BlackRock's participation signals that infrastructure cybersecurity is becoming an investable theme for financial institutions, not just strategic energy backers like Koch.
Third-order effects
- The endgame visible in the corpus is consolidation: specialist OT-security firms that raised at unicorn-scale private valuations get folded into strategics like Accenture rather than staying independent public companies.
- If financial institutions keep co-investing with industrial groups in infrastructure software, ownership of critical-system security concentrates among a few large capital pools — a governance question regulators have not yet addressed.
The trend: Critical-infrastructure cybersecurity is consolidating from venture-backed specialists into portfolios owned by consulting giants and financial institutions, with mega-rounds like Dragos's marking the peak of independent scale-up.
