Quorum Cyber: Inside the Fast-Growing Microsoft Security Powerhouse

Quorum Cyber has developed from an Edinburgh cyber security business into an international security services provider with operations across several major markets. The company protects more than 400 organisations across four continents and employs more than 350 people across the UK, United States, Canada and UAE. Its growth has been built on Microsoft security technology, experienced leadership and a strong focus on threat-led protection. The business now serves organisations facing increasingly complex cyber threats, data risks and operational security challenges.

Quorum Cyber Company Background and History

Quorum Cyber Security Limited was legally incorporated in Scotland on 7 July 2015 under company number SC510322. The business itself describes its founding year as 2016, when its cyber security operations began in Edinburgh under the leadership of Federico Charosky. This distinction is important because the legal company existed before the commercial cyber security brand became established. Today, it operates as an active private limited company based in Edinburgh.

The registered office is at First Floor Suite, West Wing, Verdant, 2 Redheughs Rigg, South Gyle, Edinburgh, EH12 9DQ. Companies House classifies its activities under information technology consultancy and other IT service activities. Its latest accounts cover the year ending 31 May 2025, while the next accounts are due for the year ending 31 May 2026. The company remains active and continues to expand its international presence.

From Edinburgh to an International Cyber Security Business

Quorum Cyber began with a clear focus on helping organisations defend themselves against digital attacks. Its stated mission is to “help good people win”, which reflects its aim of supporting businesses, institutions and other organisations against cyber criminals. Over time, the business expanded from its Scottish base into North America and other regions. It now combines local expertise with an international service model.

That expansion has taken the company beyond the traditional role of a security consultancy. Its teams now include security analysts, threat hunters, incident responders, forensic specialists and technical experts. These professionals support clients before, during and after cyber incidents. The company states that its technical teams have more than 1,000 years of combined Microsoft and cyber security experience.

Quorum Cyber Quick Info

Quorum Cyber and Microsoft Security

A major part of the company’s identity is its close relationship with Microsoft. It is a Microsoft Solutions Partner for Security and a member of the Microsoft Intelligent Security Association, also known as MISA. It is also a Microsoft Security Copilot Partner. These relationships place Microsoft technology at the centre of its cyber security services.

The company works with tools such as Microsoft Sentinel, Microsoft Defender and the wider Microsoft Security ecosystem. Its teams hold more than 1,000 Microsoft certifications, showing a deep level of technical training across its workforce. This allows the company to build security services that work closely with Microsoft cloud, identity, endpoint and data protection systems. The goal is to help clients detect threats faster and respond with greater control.

The Clarity Platform

One of the company’s most important assets is its Clarity platform. The platform brings Microsoft security signals into a more practical environment where teams can understand risks and take action. It is designed to reduce noise, improve visibility and help organisations focus on the most serious threats. This gives customers a clearer view of what is happening across their digital environment.

Clarity also supports the delivery of the company’s managed security services. Its wider service range includes managed detection, professional security services, cloud security, data security and cyber risk support. The platform helps bring these areas together within one operating model. This makes security decisions easier for organisations with complex IT systems.

Quorum Cyber Services and Specialities

Quorum Cyber provides a broad range of cyber security services to organisations in different industries. Its main strengths include managed security services, security consulting, Azure security, penetration testing and vulnerability management. It also works in threat analysis, threat modelling, cyber security compliance and security strategy. Security Operations Centre services form another important part of its offering.

Managed Security and Threat Response

Managed security services help customers monitor digital threats without having to build every capability internally. The company’s analysts watch for suspicious activity, investigate incidents and support fast action when risks are confirmed. This service model is especially valuable for organisations that lack large in-house security teams. It also provides access to specialised knowledge at all hours.

Incident response has become another major strength, especially after the company expanded in North America. Cyber attacks can cause serious disruption, financial loss and reputational damage. Rapid investigation and recovery are therefore critical. The business has strengthened these capabilities through both internal development and acquisitions.

Major Acquisitions and International Growth

In September 2024, the company acquired Canada-based Difenda, a Microsoft Solutions Partner for Security. The deal expanded its operations in Canada and strengthened its Microsoft-focused managed security capabilities. Difenda brought experienced staff, existing customers and established security services into the wider group. The business later moved under the Quorum Cyber brand.

A second major acquisition followed in December 2024 with the purchase of US-based Kivu Consulting. Kivu brought strong capabilities in incident response, digital forensics and cyber crisis management. This acquisition gave the group greater depth in handling serious cyber incidents, including complex recovery work. Together, the two acquisitions strengthened its position in North America.

Offices Across Key Markets

The company’s headquarters remain at Verdant, 2 Redheughs Rigg in Edinburgh. Its United States office is located at 501 E Kennedy Boulevard, Suite 1400, Tampa, Florida. Its Canadian office is based at 1375 North Service Road East, Suite 102, Oakville, Ontario. The wider workforce also includes employees operating across the UAE.

Quorum Cyber follows a hybrid working model. Its working practices are designed to adjust to customer needs and international demands. Staff can work in collaborative office settings while also benefiting from flexible arrangements. This approach supports a workforce spread across several countries and time zones.

He has also been Chief Operating Officer of Secureworks and an Executive Director at Dell Technologies. His background centres on scaling international technology and cyber security businesses.

Greg Aitken serves as Chief Financial Officer and has held the role since 2021. A Chartered Accountant, he has about 15 years of experience across financial services and IT services. John Wallace is Chief People Officer and has more than 20 years of experience in human resources. His previous employers include RBS, Tesco Bank, Barclays and Gulf International Bank.

Mike LaPeters serves as Chief Revenue Officer and has about 30 years of experience in security, infrastructure and software sales.

Founder Federico Charosky

Federico Charosky is the founder and a Non-Executive Director of the company. Born in October 1982, he is 43 years old as of September 2026. He has spent about 20 years working in risk and cyber security across Europe, the Middle East and the Americas. His career has included work with major blue-chip and FTSE 100 companies.

He has also served as Head of Security at a Middle Eastern bank. Charosky joined the board of Quorum Cyber Security Limited in April 2016 and remains an active director. His role has changed as the business has grown, but he continues to be closely connected with its strategy and identity. Kevin Hanes now leads the company as CEO.

Investment and Corporate Leadership

Charlesbank Capital Partners has an important role in the company’s current growth phase. Dhruva Kaul, Principal at Charlesbank, focuses on investments within its Technology Opportunities strategy. Darren Battistoni is Managing Director and Co-Head of Technology Opportunities at the investment firm. He has more than 20 years of experience investing in enterprise technology.

Their presence within the wider leadership structure reflects the role of investment capital in supporting international expansion. The company has moved through the start-up and scale-up stages into a larger global cyber security operation. Investment has supported acquisitions, recruitment, platform development and market expansion. This has helped the organisation build greater reach in both Europe and North America.

Awards, ESG and Industry Recognition

The company has gained important recognition within the Microsoft security ecosystem. It won the Microsoft Security MSSP of the Year 2025 award, strengthening its position as a major Microsoft-focused managed security provider. It also holds Microsoft partner status across several important security areas. These achievements support its reputation in a competitive cyber security market.

The company has also received an EcoVadis Silver Medal for environmental, social and governance performance. This places it within the top 15% of companies assessed by EcoVadis during the relevant assessment period. The award reflects greater attention to sustainability, responsible business practices and corporate governance. ESG performance is becoming increasingly important for technology suppliers working with major organisations.

Workforce, Customers and Market Position

Quorum Cyber employs more than 350 people and serves more than 400 customers worldwide. Its workforce extends across the UK, US, Canada and UAE, while its customers span four continents. LinkedIn places the company in the 201–500 employee category and shows hundreds of professionals connected with the organisation and its subsidiaries. These figures show how quickly the company has expanded since its Edinburgh beginnings.

Its online reputation also reflects positive customer sentiment, although the number of consumer-facing reviews remains small. The Edinburgh business location has held a 4.7 Google rating based on three reviews, while Cloudtango has shown a 4.3 out of 5 score based on two reviews. These figures should be viewed as limited snapshots rather than broad measures of customer satisfaction. Enterprise cyber security firms often receive far fewer public reviews than consumer businesses.

The Future of Quorum Cyber

The company is positioned at the meeting point of cyber security, Microsoft cloud services, threat intelligence, data protection and artificial intelligence. Its international expansion, acquisitions and growing workforce give it greater scale than many traditional regional cyber consultancies. At the same time, its Microsoft-first strategy gives the business a clear technical identity. This focus may help it maintain a strong position as security threats become more advanced.

With more than 400 customers, over 350 employees and a rapidly growing international footprint, Quorum Cyber has moved well beyond its original Edinburgh base. Its combination of Microsoft expertise, managed security services, incident response and the Clarity platform supports organisations facing serious digital risks. Strong leadership and continued investment have also helped shape its growth. The company now stands as a significant UK-founded cyber security business with a growing global presence.
