Are you concerned about the potential vulnerabilities in your organization’s digital infrastructure that could be exploited by cybercriminals? If yes, then you need to adopt a robust Attack Surface Management (ASM) strategy. ASM solutions can help identify and mitigate any security gaps in your IT ecosystem. In this blog post, we’ll dive into the Top 5 Open Source Solutions for Attack Surface Management available to organizations of all sizes. Read on to discover which solution is best suited for your company’s unique needs!

What is Attack Surface Management?

Attack Surface Management (ASM) is a continuous process of identifying and analyzing the digital footprint of an organization to identify potential risks or vulnerabilities. It involves assessing all external-facing assets, such as websites, applications, cloud services and networked devices to determine any weak points that can be exploited by cybercriminals.

The main goal of ASM is to reduce the attack surface area of an organization’s IT infrastructure. By implementing effective ASM measures, organizations can minimize their exposure to security threats and protect themselves from cyber-attacks.

Organizations need to have a clear understanding of their digital assets’ scope and scale before embarking on an ASM strategy. This includes inventorying their hardware devices, software systems and data repositories across different environments like cloud service providers.

ASM solutions use various tools such as vulnerability scanning, penetration testing and threat intelligence gathering methods to analyze these digital assets continually and effectively. The insights gathered through these measures provide valuable information for organizations in prioritizing remediation activities based on risk severity factors.

Attack Surface Management helps better manage security risks by providing visibility into the company’s overall security posture while reducing its attack surface area.
