Armis, a San Francisco-based cybersecurity startup, has raised $435 million in a pre-IPO funding round.
The company is now valued at approximately $6.1 billion following the investment.
Founded nine years ago, Armis provides protection for critical infrastructure across Fortune 500 companies and government entities.
The startup reported annual recurring revenue of around $300 million and aims to reach $500 million before going public.
The funding will fuel growth ahead of an IPO planned for late 2026 or early 2027.
Investors in the round include the growth-equity arm of Goldman Sachs and new backer Evolution Equity Partners.
This raise underscores robust investor interest in cybersecurity firms targeting enterprise and infrastructure resilience.
