What Is Attack Surface Management?
Attack Surface Management (ASM) is the continuous discovery, analysis, and monitoring of an organisation’s digital assets that are visible to attackers. These include exposed IP addresses, cloud services, web applications, APIs, and forgotten infrastructure.
ASM tools and services help organisations identify weak points in real time before cybercriminals exploit them. As organisations grow and digitise, their attack surface increases—making ASM a key component of proactive cybersecurity.
Why ASM Matters More Than Ever
According to a 2024 IBM X-Force Threat Intelligence Index, misconfigured cloud assets and unpatched internet-facing applications were among the top 3 initial attack vectors. Meanwhile, Gartner predicts that by 2026, 20% of enterprise security budgets will be allocated to ASM solutions.
With cyberattacks becoming more sophisticated, ASM ensures that security teams stay one step ahead by maintaining visibility over dynamic and often neglected digital assets.
