FAQ's
What is Rythenox?
Rythenox is a precision-focused cyber operations company specializing in advanced access frameworks and stealth-grade tooling. We serve vetted clients in sectors where silence is not optional.
What is Marengo?
Marengo is our flagship product: a covert command-and-control framework designed for operators who require undetectable persistence, silent data access, and modular control at scale. It does not ask for access—it operates within it.
Who can use Marengo?
Marengo is not a commercial product. Access is restricted to government bodies, red teams, and select defense-aligned security professionals under strict vetting and compliance protocols.
How is Marengo different from other tools?
Marengo is not a pentesting toolkit. It's a fully integrated, low-footprint operations platform built for long-term campaigns, silent persistence, and real-time command delivery through anonymized bridges and randomized infrastructure.
