Summary

Sophos, a British security software and hardware company, has acquired London-based cybersecurity assurance firm Arco Cyber for an undisclosed sum. This acquisition aims to enhance Sophos's capacity to deliver CISO-level, AI-powered security insights to businesses via its global partner network. Arco Cyber developed a cloud platform that aggregates and correlates data from various security systems, providing visibility into control effectiveness, identifying exposures, and prioritizing remediation based on business and risk outcomes. This aligns with Sophos's CISO Advantage initiative, which equips managed service providers (MSPs) and managed security service providers (MSSPs) to offer executive-level oversight as a service. The integration of Arco Cyber's technology into Sophos Central will expand continuous security assurance, risk mapping, and compliance monitoring for customers, supporting decision-making at the executive level.
