Understanding the managed security services size is essential for evaluating the value, scope, and future potential of this critical cybersecurity sector. As enterprises increasingly depend on digital infrastructure, cloud technologies, remote work environments, and interconnected devices, the market size of managed security services has expanded dramatically. This surge reflects both the rising threat landscape and the strategic shift toward outsourced cybersecurity operations.
Industry data clearly demonstrates this momentum: Managed Security Services Market Size was estimated at 32.56 USD Billion in 2024. The industry is projected to grow from 34.91 USD Billion in 2025 to 70.03 USD Billion by 2035, at a CAGR of 7.21% during 2025–2035. This sizable growth trajectory indicates not only increased adoption but also the rising complexity of cyber risks that organizations must address.
Market size is influenced by several factors. First, the global increase in cyberattacks—ransomware, phishing, DDoS attacks, and advanced persistent threats—has pushed organizations to adopt stronger and more sophisticated security measures. Managed security service providers offer advanced monitoring tools, global threat intelligence, and incident response capabilities that internal teams often lack.
Second, cloud migration plays a significant role in expanding market size. As organizations move workloads to cloud environments, they require cloud-native security operations that are scalable and automated. MSS providers deliver solutions tailored for multi-cloud and hybrid environments, contributing to the overall increase in market value.
Third, the expansion of the remote workforce has created new vulnerabilities for businesses. Remote endpoints, unsecured home networks, and decentralized access points require continuous monitoring and protection. Managed endpoint security, identity management, and secure access control have become essential offerings shaping market size.
Additionally, regulatory pressures fuel market expansion. Enterprises must comply with strict cybersecurity frameworks, including financial sector guidelines, healthcare standards, and international data protection regulations. Managed security services help businesses meet these obligations, reinforcing demand across industries.
In conclusion, the managed security services size highlights a market driven by technological shifts, rising threats, and the global need for expert security support. As digital ecosystems evolve, the market is expected to grow even more rapidly, reinforcing MSS as a core component of enterprise cybersecurity strategy.
