Let's Get STARTED

The cyber security landscape is more complex and dynamic than ever, with attack surfaces expanding at a rapid rate thanks to remote working, IoT, cloud adoption and advanced technologies. Meanwhile, cyber threats are becoming ever more sophisticated.  As IT complexity rises, it’s vital for businesses to find a way to gain visibility across diverse assets. This is where Cyber Asset Attack Surface Management (CAASM) comes into play.

CAASM is a security platform that provides businesses with a real-time consolidated view of all physical and digital assets within their network. CAASM helps to identify, manage, and reduce potential security gaps along the network attack surface, consolidating, compiling and analysing data from different tools and systems. In this way, it helps security teams stay ahead of threats, ensuring they know exactly what’s in their environment at all times, navigating increasingly complex and distributed systems and streamlining security processes.

What is CAASM?

CAASM integrates data from multiple tools and systems to create a unified, real-time view of an organisation’s physical and digital assets. By leveraging this visibility, teams can define specific security criteria, prioritise remediation efforts, and enable faster threat response. CAASM bridges the gap between security operations and traditional IT asset management, offering several benefits compared to similar security technologies:

  • Attack Surface Management (ASM) - CAASM is essentially continuous attack surface management (ASM) with always-on monitoring, but it operates through the lens of an organisation's internal and external cyber assets.
  • External Attack Surface Management (EASM) -while EASM focuses solely on external-facing assets, CAASM also includes internal assets, providing a complete picture of the attack surface.
  • Digital Risk Protection (DRP) - like DRP, CAASM, identifies risks associated with digital assets. However, it also provides broader visibility across the network and continuous asset discovery in one unified solution
  • API Attack Surface Management (AASM) - CAASM offers a broader scope than AASM, covering APIs alongside all other assets within the attack surface for more comprehensive management.
  • Risk-Based Vulnerability Management (RBVM) -CAASM incorporates risk-based principles used in RBVM but applies them across the entire attack surface, integrating asset visibility and risk-based prioritisation into a single platform. 

CAASM is an evolution and integration of various other security technology solutions, providing a unified view of all internal and external assets and their associated vulnerabilities. This holistic perspective enables comprehensive threat management and helps organisations proactively address risks across an increasingly complex and distributed attack surface.

 

The Importance of CAASM

Asset and vulnerability management are vital to enable businesses to stay ahead of evolving cyber threats. However, implementing CAASM delivers additional benefits, providing a unified view of an organisation’s entire attack surface and empowering security teams to be more proactive. In fact, CAASM offers many key business benefits:

  • Enhanced Visibility - security teams have complete visibility into every asset, regardless of location, eliminating blind spots across the network.
  • Proactive Security - CAASM continuously monitors and analyses the attack surface, catching emerging vulnerabilities and risk exposures early.
  • Improved Compliance - CAASM simplifies compliance documentation and helps organisations demonstrate adherence to regulatory standards.
  • Lower Risk Profile - using continuous automation to discover exposed assets helps businesses address risk in previously unknown areas.
  • Smaller Attack Surface - by identifying vulnerabilities quickly and remediating them, organisations can reduce the number of potential access points for threat actors.
  • Stronger Partnerships - CAASM fosters collaboration between IT and security teams, with asset data flowing seamlessly between departments.

While CAASM offers significant benefits, to be effective, it’s vital for it to be implemented and managed in line with best practices. When adopting CAASM, organisations should begin by identifying all potential attack vectors and working with various departments to align their efforts. Successful implementation depends on clear roles and responsibilities, strong remediation workflows, and constant monitoring, ensuring that new assets are integrated, and vulnerabilities are continuously assessed.

 

Have You Adopted CAASM?

Adopting CAASM is a fundamental step in streamlining and enhancing your organisation’s cyber security practices. It enables you to consolidate distributed assets and gain a holistic view of your expanding IT environment. By improving visibility and response, you can strengthen risk management and compliance efforts, ultimately bolstering your cyber security posture.
