Frequently asked questions
The MSSP market is rapidly growing due to increasing cybersecurity threats and the complexity of managing security in-house. As of 2025, the global managed security services market is valued at over $50 billion and is expected to continue growing at a compound annual growth rate (CAGR) of around 15-20% over the next several years. This growth reflects rising demand for outsourced cybersecurity expertise across industries worldwide.
An MSP (Managed Service Provider) typically manages a broad range of IT services such as network management, helpdesk support, and system maintenance. A SOC (Security Operations Center), on the other hand, is a dedicated facility or team focused solely on cybersecurity — monitoring, detecting, and responding to threats in real-time.
An MSSP often provides SOC services as part of their offering, delivering specialized 24/7 security monitoring and incident response that most traditional MSPs do not.
The cost of managed security services varies widely based on the scope of services, company size, complexity of the IT environment, and the level of threat monitoring required. Small to medium businesses may pay anywhere from $1,000 to $5,000 per month, while larger enterprises with comprehensive needs can expect costs ranging from $10,000 to $100,000+ monthly. Many MSSPs offer flexible pricing models, including flat monthly fees, per-device pricing, or usage-based billing to fit different budgets.
