Global Cloud Access Security Brokers Market Size study & Forecast, by Solution (Data Security, Threat Protection), Deployment Mode (IaaS, PaaS, SaaS), Enterprise Size, End-use and Regional Forecasts 2025-2035

The Global Cloud Access Security Brokers (CASB) Market is valued at approximately USD 9.44 billion in 2024 and is projected to expand at a CAGR of 18.3% during the forecast period 2025–2035, reaching nearly USD 59.95 billion by 2035. CASBs, functioning as critical intermediaries between cloud service users and providers, have emerged as indispensable tools for securing data flows, ensuring compliance, and protecting enterprises from ever-intensifying cyber threats. Their purpose extends from monitoring user activity and enforcing security policies to detecting malware and managing sensitive data in real time. The widespread adoption of Software-as-a-Service (SaaS) applications across industries, the shift toward hybrid cloud infrastructures, and stringent data privacy regulations are fueling unprecedented demand for CASBs. Enterprises increasingly lean on these platforms to bridge security gaps left unaddressed by traditional firewalls and endpoint defenses, as the migration of sensitive operations into the cloud accelerates worldwide.

The escalation of sophisticated cyberattacks, including ransomware, insider threats, and account takeovers, has amplified the urgency for enterprises to strengthen their cloud defenses. CASBs provide unparalleled visibility and control across cloud applications, enabling organizations to uncover shadow IT, prevent data exfiltration, and comply with evolving frameworks such as GDPR and HIPAA. A surge in multi-cloud strategies has further intensified the requirement for CASBs, as businesses struggle to maintain consistent security across IaaS, PaaS, and SaaS platforms. For instance, the rapid adoption of collaboration tools and remote working ecosystems has multiplied data sharing risks, prompting organizations to adopt CASBs not merely as security gatekeepers but as enablers of secure digital transformation. Despite the growth trajectory, integration complexities and high deployment costs may pose obstacles, particularly for small enterprises, yet these challenges also create avenues for innovation in simplified and modular CASB offerings.

SaaS Deployment Expected to Dominate the Market

Among the deployment models, SaaS is anticipated to dominate the global CASB market, supported by the massive proliferation of cloud-hosted applications in nearly every industry vertical. Organizations increasingly rely on SaaS solutions for CRM, HR, and collaboration purposes, yet their security challenges grow exponentially with sensitive data scattered across disparate platforms. CASBs in the SaaS segment deliver real-time protection, policy enforcement, and granular visibility, which are essential for enterprises navigating compliance-heavy environments. While IaaS and PaaS deployments are gaining momentum, particularly with businesses modernizing their core infrastructures, SaaS remains at the forefront of CASB adoption, serving as the backbone of enterprise cloud security strategies.

Data Security Solutions Lead in Revenue Contribution

When viewed through the lens of solution type, data security currently contributes the largest revenue share in the CASB market. With regulatory mandates emphasizing data confidentiality, integrity, and availability, enterprises are investing heavily in CASB solutions capable of encrypting sensitive information, applying tokenization, and preventing unauthorized data sharing. Data security tools are embedded at the heart of CASB adoption, ensuring enterprises mitigate risks associated with cloud data breaches and insider threats. Meanwhile, threat protection is identified as the fastest-growing segment, propelled by the rising sophistication of cloud-native attacks, malware injection attempts, and phishing campaigns targeting cloud environments. Together, these solutions underscore the dual priority: protecting enterprise data at rest and combating external threats in motion.

Regionally, North America holds the largest share of the global CASB market, driven by the region’s early adoption of cloud services, strong regulatory frameworks, and concentration of global technology giants. The United States remains the epicenter, where BFSI, healthcare, and defense industries have set high benchmarks for cloud security adoption. Meanwhile, Asia Pacific is forecasted to grow at the fastest pace throughout 2025–2035, attributed to aggressive digital transformation initiatives, rapid cloud adoption, and growing cybersecurity investments across China, India, and Southeast Asia. Europe continues to demonstrate steady growth, spurred by compliance mandates like GDPR and the high adoption rate of secure collaboration tools. Latin America and the Middle East & Africa, though relatively nascent, are witnessing heightened demand for CASBs as enterprises in these regions accelerate their digital modernization journeys.
