GCP completes investment in leading global MSSP, SecurityHQ

Growth Capital Partners (“GCP”) is pleased to announce the successful minority investment in SecurityHQ, a tech-enabled full suite Managed Security Service Provider (“MSSP”) offering MDR services through its global Security Operations Centres (“SOCs”), alongside threat and risk intelligence services, and device management and protection.

SecurityHQ supports customers in managing their cyber risk by continuously monitoring their technology estates, detecting and analysing threats and responding to breaches. It combines the expertise of security analysts with automation, analytics, and real-time threat intelligence through its proprietary SHQ Response technology platform, to provide clients with a white-glove, high-touch, 24/7 cybersecurity service.

Founded by CEO Feras Tappuni, SecurityHQ has scaled rapidly at a CAGR of 40%+, built a team of 400+ cybersecurity experts and expanded across six geographies.

The partnership between GCP and SecurityHQ will support the business in enhancing its go-to-market strategy, supporting further innovation across its proprietary technology platform and service offering, strengthening operational and financial systems to enhance scalability, and supporting international expansion, including in the US market where the business is experiencing significant demand for its services.

As the leading UK investor specialising in the Knowledge Economy, this investment partnership with SecurityHQ aligns perfectly with GCP’s strategy of backing ambitious, technology-led businesses that deliver critical value for clients through data, insight, and innovation. SecurityHQ exemplifies this through its tech-enabled managed services, deep cybersecurity expertise, and commitment to protecting organisations from evolving digital threats.

Feras Tappuni, CEO, SecurityHQ commented:

“We are delighted to be partnering with GCP. When searching for a partner, I wanted someone who got our sector and understood our culture. GCP stood out because of their deep understanding and track record within cybersecurity and supporting scaling businesses which marries perfectly with our growth aspirations. We are immensely proud of what we have built at SecurityHQ; a global, scaled MSSP with a proposition valued by our clients and a fantastic reputation embodied by our high quality staff. We are very excited by what we can achieve in partnership with GCP as part of this next step in our journey.”

Ravi Monteiro, Partner, GCP, commented:

“We have been hugely impressed by what Feras and the wider SecurityHQ team have achieved in building a global, tech-enabled cybersecurity business with a strong reputation for excellence and client service. Cybersecurity remains an essential service for organisations, with the frequency, complexity and cost of breaches continuing to expand in an ever-evolving threat landscape. Against this backdrop, SecurityHQ has developed, a market-leading MDR platform providing round the clock coverage for its international client base alongside specialist cyber services. We are delighted to be partnering with Feras and his team at such an exciting point in their journey and look forward to supporting them as they continue to scale and innovate in this fast-growing sector.”
