Growth Capital Partners has taken a minority stake in SecurityHQ, a global managed security service provider focused on managed detection and response. Financial terms were not disclosed. The investment comes as demand for outsourced security operations continues to rise, particularly among organizations that lack the scale or resources to run an in-house SOC.Founded by Feras Tappuni, SecurityHQ has built a global footprint with more than 400 security professionals operating across six geographies. The company delivers 24/7 monitoring, detection, and response through a combination of human analysts and its proprietary SHQ Response platform. For mid-market customers, this model offers a practical alternative to building and staffing internal security operations teams.GCP’s investment will support SecurityHQ’s next phase of growth. That includes strengthening its go-to-market execution, continuing platform development, and improving operational scalability. A key focus will be expansion in the U.S. market, where demand for managed security services remains strong as threat activity increases and security teams remain stretched.The deal marks the final investment from GCP’s Fund V. The firm is now deploying capital from its £411 million Fund VI, raised in 2025, which has already seen its first investment with Optima Partners. For SecurityHQ, the backing provides additional capital and support as it looks to scale its MDR business globally while maintaining consistent service delivery across regions.
