Arco Cyber is a UK-based cybersecurity assurance company, founded in 2022 and led since inception by CEO Matt Helling, a 19-year veteran of infrastructure provider Softcat. The company operates a continuous cyber risk and control assurance platform that consolidates data across a customer’s security stack to show control effectiveness, surface exposures, and prioritize remediation using risk-based metrics, rather than relying on point-in-time audits.
Sophos acquired Arco Cyber in February 2026 as the foundation of Sophos CISO Advantage, a new initiative combining agentic AI, integrated platforms, and human expertise — delivered through Sophos’s MSP and MSSP partner network — to give organizations without a dedicated CISO access to CISO-level security judgment and compliance guidance. Terms were not disclosed.
Innovation Matrix Assessment
Built a continuous control-assurance platform and became the centerpiece of a major acquirer's new CISO-as-a-service strategy within roughly four years of founding.
Converts scattered security-stack data into ongoing, risk-scored control effectiveness metrics that security teams and partners can act on directly rather than waiting for periodic audits.
Acquired by Sophos in February 2026 specifically to anchor its new Sophos CISO Advantage initiative -- a strong strategic endorsement from a major security vendor.
Continuous control assurance is an incremental evolution of established GRC and security-posture-management approaches rather than a wholly new category.
No independent customer benchmarking is publicly available; efficacy rests on Sophos's acquisition due diligence and the founding team's industry background rather than published third-party validation.
Compliance pressure and the shortage of CISO-level talent at small and mid-sized organizations make continuous, partner-deliverable assurance durably relevant.
Why CISOs Should Care
Gives resource-constrained security teams -- and organizations with no dedicated CISO at all -- continuous, risk-scored visibility into control effectiveness across their stack, turning point-in-time compliance audits into an ongoing assurance process.
What Makes It Different
Built specifically as a continuous control-assurance layer that consolidates evidence across the existing security stack into risk-based metrics, rather than as a GRC questionnaire tool or a standalone audit product.
The Matrix Verdict
63/100 — INCREMENTAL INNOVATOR
A young (2022) UK assurance platform whose acquisition by Sophos to anchor a flagship new CISO-as-a-service initiative is a strong momentum signal; Meaningful Innovator given the speed of that validation for a four-year-old company.
Editorial Note: Claims vs. Verified Findings
The acquisition, founding date, and CEO background are corroborated across Sophos's own press release and independent trade coverage (BankInfoSecurity, Techzine); deal financial terms were not disclosed by either party.
