What is it?
A Cloud Access Security Broker (CASB) is a security tool positioned between an organisation’s users and their cloud services. It provides visibility, control, and protection across multiple cloud platforms. By applying consistent policies, enforcing data protection measures, and detecting abnormal behaviour, CASBs help organisations safely embrace cloud technology without sacrificing security.
What could happen?
In the absence of a CASB, cloud activities may go unchecked. Users could inadvertently upload sensitive data to unapproved services, misconfiguration might expose critical assets, and malicious insiders or attackers could exploit blind spots. Without the oversight and policy enforcement a CASB provides, organisations risk losing data integrity, breaching compliance mandates, and sustaining reputational damage.
What to do about it?
Foundational: Deploy a basic CASB solution to gain immediate visibility into sanctioned and unsanctioned cloud services, and flag risky activities.
Outcome: Establishes a foundational understanding of cloud usage, enabling prompt remediation of obvious misconfigurations.
Enhanced: Configure DLP, encryption, and access policies within the CASB to protect sensitive data. Integrate it with identity solutions for consistent user authentication and authorisation across all cloud applications.
Outcome: Creates a robust barrier against data leaks and unauthorised access, aligning cloud governance with internal security standards.
Comprehensive: Integrate CASB with SIEM, SOAR, and threat intelligence platforms to achieve automated detection and response, advanced analytics, and continuous compliance monitoring. Continuously refine policies as new applications and threats emerge.
Outcome: A dynamic, intelligent cloud security ecosystem that pre-emptively neutralises risks, optimises cloud resource usage, and maintains regulatory compliance at scale.
