Application security is becoming a larger part of cybersecurity spending as organizations depend more heavily on web applications, mobile platforms, APIs, cloud-native environments, and software-driven business processes. But an important question is not just how much organizations spend on application security. It is how much of that spending is being directed toward managed services.
Based on available 2025 industry estimates, the global application security sector was valued at approximately $10.6 billion, while managed application security services generated around $872.8 million. On this basis, managed services accounted for approximately 8.2% of total application security spending in 2025.
This percentage provides an interesting view of how organizations are approaching application protection. Instead of relying entirely on internal security teams, many businesses are increasingly using external providers for continuous monitoring, vulnerability identification, security testing, threat detection, and other ongoing activities.
Why Are Managed Application Security Services Gaining Attention?
Modern applications are rarely isolated systems. Organizations may operate applications across public clouds, private infrastructure, hybrid environments, APIs, containers, and third-party platforms. Keeping security controls consistent across these environments can become difficult, particularly when internal teams are already managing large numbers of alerts and vulnerabilities.
Managed services can help address this operational challenge by providing continuous security support. Depending on the provider and service model, this can include vulnerability monitoring, application security testing, threat detection, security assessments, remediation support, and ongoing monitoring.
The skills shortage is another important factor. Gartner has noted that organizations are increasingly using managed security functions from specialized providers because maintaining sufficient in-house cybersecurity expertise can be difficult. In India, for example, Gartner projected security services spending to grow 19% in 2025, with organizations increasingly relying on external providers to address cybersecurity skills gaps.
Managed Services Represent a Larger Share of Application Security Services
The 8.2% figure becomes more meaningful when managed services are compared with the services portion of application security spending.
Industry estimates place the global application security services segment at approximately $3.5 billion in 2025. Managed services generated about $872.8 million during the same year. That means managed services represented roughly 25% of application security service revenue.
This distinction is important.
Managed services do not yet represent the majority of overall application security spending because organizations continue to invest heavily in security software, testing platforms, and other solutions. However, within the services category, managed offerings already represent a meaningful portion of spending.
The direction of growth is also notable. Managed application security services are estimated to expand at a 22.9% CAGR from 2025 to 2033, reaching approximately $4.56 billion by 2033.
What Is Driving the Shift Toward Managed Security?
One of the biggest factors is the growing complexity of application environments.
Cloud migration and hybrid architectures have increased the number of applications, APIs, workloads, and connections that organizations need to protect. At the same time, software development cycles have become faster. Security teams are therefore expected to identify vulnerabilities without slowing down development.
This is where managed services can provide operational value. External security specialists can continuously monitor applications and help organizations respond to vulnerabilities while internal teams concentrate on development, infrastructure, governance, and business priorities.
The broader movement toward DevSecOps is also relevant. Security is increasingly being integrated into development workflows rather than being treated as a final-stage assessment. Precedence Research’s analysis of the [DevSecOps industry] highlights the importance of application security within secure software development, with application security accounting for approximately 33% of the DevSecOps sector in 2025.
Healthcare Could Be an Important Area for Managed Application Security
Healthcare organizations have particularly strong reasons to strengthen application security. Hospitals, health systems, insurers, laboratories, and digital health companies manage sensitive patient information while increasingly relying on cloud platforms, connected devices, patient portals, telehealth applications, and other digital services.
This creates a security environment where application vulnerabilities can have consequences beyond financial losses. Data privacy, regulatory requirements, operational continuity, and patient trust are all connected to cybersecurity.
Precedence Research’s coverage of [healthcare cybersecurity] shows the continuing importance of security services alongside technology-based protection. For example, its North America healthcare cybersecurity analysis estimates that services represented 35% of spending in 2025, supported by demand for consulting, implementation, and managed security services.
What Does the 8.2% Share Tell Us?
The estimated 8.2% share suggests that managed services are already an established part of application security spending, but there is still considerable room for expansion.
The stronger signal comes from the growth rate. A projected 22.9% CAGR for managed application security services is considerably faster than the overall application security sector’s projected growth of about 18.8% from 2026 to 2033.
In practical terms, this means organizations are not simply increasing their application security budgets. They are also changing how security capabilities are delivered.
For organizations with limited cybersecurity personnel, complex cloud environments, or requirements for continuous monitoring, managed services can provide access to specialized expertise without requiring every capability to be developed internally.
