Understanding the Differences Between CTEM, EASM, and ASM | TRaViS ASM: A Comprehensive Cybersecurity Breakdown


Introduction


In today's cybersecurity landscape, organizations face an ever-growing array of external and internal threats. With complex digital footprints and the rapid pace of technological change, solutions like CTEM (Continuous Threat Exposure Management), EASM (External Attack Surface Management), and ASM (Attack Surface Management) are becoming indispensable. However, for many cybersecurity professionals, understanding the differences between these approaches is crucial for building a robust security posture.

In this guide, we will delve into the specifics of each methodology, highlight their differences, and explain how TRaViS ASM, an advanced platform from Seron Security, integrates these technologies to provide organizations with a unified solution for managing their cybersecurity risks.

What is CTEM (Continuous Threat Exposure Management)?

Continuous Threat Exposure Management (CTEM) is an innovative approach to identifying, prioritizing, and managing threats on a continuous basis. Unlike traditional, periodic vulnerability assessments, CTEM focuses on ongoing threat intelligence and security assessments to keep an organization ahead of potential cyberattacks.

CTEM’s key features include:

  • Continuous monitoring of your attack surface.
  • Proactive risk management based on real-time intelligence.
  • Prioritization of vulnerabilities to ensure that high-risk threats are addressed first.
  • Integration with threat intelligence feeds to detect emerging threats before they become critical.

  1. Asset Discovery & Mapping
    Leverage TRaViS's automated discovery to uncover hidden digital assets, shadow IT, and new endpoints across your environment.
  2. Exposure Detection
    Analyze these assets for vulnerabilities, weak configurations, and exposed APIs. TRaViS continuously scans for emerging threats, bringing real-time insights into your dashboard.
  3. Risk-Based Prioritization
    Using the TRaViS Threat Prioritization Algorithm, vulnerabilities are ranked by severity, business impact, and exploitability, allowing your team to address the most urgent issues first.
  4. Mitigation Mobilization
    Deploy mitigation strategies and patch management systems through TRaViS integrations with third-party tools (SIEM, SOAR). This stage focuses on remediating prioritized risks effectively.
  5. Remediation Validation
    Once mitigations are applied, TRaViS validates and monitors these fixes through automated testing and continuous vulnerability reassessment, ensuring a robust security posture.

What is EASM (External Attack Surface Management)?

External Attack Surface Management (EASM)
focuses on discovering, monitoring, and managing all externally exposed digital assets such as websites, IP addresses, APIs, and third-party services. As businesses expand their online presence, they inadvertently create a larger attack surface, which could be exploited by cybercriminals. 

The core functionality of EASM includes:

  • Discovering new digital assets that may be publicly exposed but not currently monitored.
  • Monitoring external assets for vulnerabilities such as exposed APIs, credentials, or misconfigurations.
  • Reducing the risk of unauthorized access by continuously scanning your organization's public-facing infrastructure.

What is ASM (Attack Surface Management)?

Attack Surface Management (ASM) is a broader term that encompasses the identification and monitoring of both internal and external digital assets. Unlike EASM, which only focuses on external assets, ASM covers the entire attack surface—both internal networks and publicly exposed systems.

ASM solutions, like TRaViS ASM, provide comprehensive visibility and monitoring across your digital footprint, enabling organizations to:

  • Map internal and external assets and their vulnerabilities.
  • Monitor the attack surface continuously for any potential threats.
  • Prioritize vulnerabilities based on risk factors such as exploitability and impact.

Core Functionality

  • CTEM delivers continuous threat assessments and vulnerability management.
  • EASM focuses solely on external asset management and discovery.
  • ASM is a more comprehensive solution that covers both internal and external attack surfaces.


Use Cases

  • CTEM is ideal for organizations that require constant vigilance against emerging threats.
  • EASM is tailored for companies concerned about their external exposure and the risks associated with public-facing systems.
  • ASM is suited for organizations with complex IT environments, needing both internal and external coverage.


Role in Vulnerability Management

  • CTEM ensures that vulnerabilities are identified and prioritized in real-time.
  • EASM helps companies minimize their exposure by discovering public-facing risks.
  • ASM provides comprehensive coverage, ensuring that all assets—internal and external—are monitored and protected.


Integration with Other Tools

  • CTEM integrates seamlessly with SIEM and SOAR tools to automate response to high-risk threats.
  • EASM connects to external monitoring tools, offering a clear picture of your external exposure.
  • ASM works across various internal and external systems, offering integration with SIEMs, threat intelligence platforms, and more.
