Introduction to Xpanse

Xpanse, a dedicated business unit of Palo Alto Networks, specializes in Automated Attack Surface Management (ASM). In an era where organizations increasingly rely on digital infrastructure, managing and securing the expansive attack surface has become paramount. Xpanse provides a robust solution to identify, evaluate, and mitigate cybersecurity risks across an organization’s global internet assets.

Comprehensive Asset Discovery

Identifying All Internet-Facing Assets

One of the foundational capabilities of Xpanse is its Asset Discovery. This process involves continuously scanning the internet to discover all devices, domains, and services associated with an organization. Unlike traditional asset management systems that rely on manual inputs or limited visibility, Xpanse autonomously identifies both sanctioned and unsanctioned assets, including those that may have been overlooked or unmanaged.

Key Features of Asset Discovery

• Comprehensive Scanning: Xpanse scans over 500 billion internet-facing assets daily, ensuring exhaustive coverage.
• Real-Time Updates: The platform maintains a continuously updated inventory, reflecting changes in the organization's digital footprint instantaneously.
• Uncovering Hidden Assets: By identifying assets that organizations may not be aware of, Xpanse reduces blind spots that could be exploited by malicious actors.

Risk Evaluation and Prioritization

Assessing and Ranking Vulnerabilities

Once assets are identified, Xpanse evaluates the risk associated with each one. This involves analyzing potential vulnerabilities, misconfigurations, and unauthorized exposures that could present entry points for cyberattacks. Utilizing advanced machine learning algorithms, Xpanse prioritizes these risks based on their potential impact and exploitability, enabling organizations to focus their remediation efforts where they are most needed.

Components of Risk Evaluation

• Vulnerability Identification: Detects misconfigurations, outdated software, and other vulnerabilities across all internet-facing assets.
• Risk Scoring: Assigns risk scores to vulnerabilities, facilitating informed decision-making regarding mitigation strategies.
• Prioritization Engine: Determines which vulnerabilities pose the greatest threat, optimizing resource allocation for remediation.

Mitigation Strategies

Proactive Risk Management

Mitigation is a critical aspect of ASM, and Xpanse excels in providing actionable insights to reduce identified risks. Through its native policy engine, Xpanse highlights policy violations and integrates with a plethora of security tools, facilitating swift and effective remediation actions. This integration capability ensures that vulnerabilities are addressed promptly, thereby minimizing the window of opportunity for potential attackers.

Mitigation Features

• Native Policy Engine: Enforces security policies across all identified assets, ensuring compliance and reducing vulnerabilities.
• Integration with Security Tools: Seamlessly connects with existing security infrastructures, such as SIEMs and SOAR platforms, to enhance overall security posture.
• Automated Remediation: Facilitates the automatic application of patches and configuration changes to mitigate identified risks.

Integration and APIs

Enhancing Existing Security Frameworks

Xpanse offers robust APIs and integration capabilities that allow organizations to incorporate ASM data into their existing security workflows. This interoperability ensures that the insights provided by Xpanse are actionable and can be leveraged within broader security strategies, thereby reducing the Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR) to security incidents.

Integration Capabilities

• API Access: Provides programmatic access to ASM data, enabling custom integrations and automation.
• Third-Party Integrations: Connects with a variety of security tools, including firewalls, SIEMs, and SOAR platforms.
