Streamlined Vulnerability Management with SOCRadar’s Comprehensive Modules
SOCRadar’s Attack Surface Management, Supply Chain Intelligence, and Vulnerability Management modules offer an integrated approach to tackling complex vulnerabilities like those recently identified in FortiGuard products.
The Attack Surface Management module is crucial for identifying and monitoring external-facing assets, including those running vulnerable versions of software. It continuously scans the organization’s digital footprint, pinpointing at-risk assets and facilitating swift action.
Concurrently, the Supply Chain Intelligence module enhances this protection by evaluating the security posture of third-party vendors. It alerts organizations to vulnerabilities disclosed by suppliers, such as FortiGuard, ensuring that any potential risks are promptly managed. This module provides critical insights into how these vulnerabilities might impact an organization through its supply chain, elevating the importance of comprehensive vendor risk management.
In conjunction, SOCRadar’s Vulnerability Management module plays a key role in the identification and prioritization of vulnerabilities. It not only scans for known vulnerabilities within an organization’s infrastructure but also offers context-based prioritization, considering factors such as exploitability, impact, and the criticality of affected assets. This approach is especially effective in managing widespread vulnerabilities, ensuring that remediation efforts are targeted and efficient.
