client verticals
WHO do we work with ?
Financial Services
Cybersecurity in the financial services sector is one of the highest priorities in the global economy. Banks, credit unions, investment firms, and insurers are prime targets for cybercriminals, jeopardizing economic & national stability.
Healthcare
Cybersecurity in healthcare is one of the most critical — and most targeted — areas of cybersecurity today. Healthcare organizations manage vast amounts of sensitive patient data, rely on networked medical devices, and often operate under tight budgets and legacy systems — all of which make them prime targets for cybercriminals.
Higher Education
Cybersecurity in higher education faces distinct and growing challenges due to the open, collaborative, and decentralized nature of academic environments. Unlike corporate settings with strict control over data and devices, universities must balance accessibility with security — often across thousands of users and systems.
Local Government
Cybersecurity in local governments is a growing concern — these institutions manage critical public services but often operate with limited budgets, outdated systems, and small IT teams. They’re a frequent target for cybercriminals and nation-state actors alike Because they handle sensitive citizen data and infrastructure.
Manufacturing
Cybersecurity in manufacturing faces a unique set of challenges because of the convergence between traditional IT systems and OT systems — such as industrial control systems (ICS), SCADA, and IoT devices. Lack of network visibility in OT environments makes it difficult to detect and respond to threats.
Retail
Cybersecurity in the retail industry is a major concern because retailers handle large volumes of payment data, customer information, and supply chain systems — all of which are attractive targets for cybercriminals.
State Government
Cybersecurity in state government is a critical and complex issue because state agencies manage enormous amounts of sensitive data. State governments are prime targets for cyberattacks because they store PII for millions of residents, operate critical infrastructure, manage election systems and voter data and often run on legacy IT systems that are difficult to secure.
Technology
Cybersecurity in the technology sector is both foundational and high-stakes — because tech companies not only rely on digital systems to operate, they build and maintain the very tools other industries depend on for security. A cyberattack on a tech firm can therefore create ripple effects across entire supply chains, governments, and global infrastructure.
