FusionX

FusionX is an Arlington, Virginia-based cybersecurity firm that provides cyber-attack simulation, threat modeling, cyber-investigations, and security risk advisory services to large enterprise clients. The company specializes in identifying complex network vulnerabilities and defending against advanced persistent threats for Fortune 100 organizations operating across the financial services, critical infrastructure, technology, government, and manufacturing sectors. Operating primarily through specialized consulting and advisory contracts, the firm conducts comprehensive security assessments to help large-scale enterprises evaluate and respond to sophisticated digital risks before any malicious exploitation occurs. In August 2015, the business was acquired by the global professional services company Accenture for an undisclosed financial transaction amount, subsequently integrating its specialized threat capabilities directly into the acquirer's broader corporate security practice. FusionX was originally established as an independent entity in 2010 by industry co-founders Matthew Devost and Tom Parker.
