How API Observability is
Redefining Cybersecurity
in the Cloud Era

The rapid adoption of cloud technologies has revolutionized how businesses operate, enabling scalability, flexibility, and innovation. However, as organizations migrate their operations to the cloud, the complexity and volume of API traffic have surged, creating new cybersecurity challenges. APIs, which are the backbone of cloud services, now represent one of the most significant attack surfaces for cybercriminals.

API observability has emerged as a cornerstone of modern cybersecurity strategies, offering end-to-end visibility, real-time threat detection, and actionable insights. Rakuten SixthSense API Security exemplifies how observability tools can safeguard APIs, ensuring data integrity and seamless operations in multi-cloud environments.

The Role of API Observability in Cloud Security

API observability involves monitoring, analyzing, and understanding API traffic and behavior to ensure security, performance, and compliance. In the cloud era, this capability is critical to addressing the unique challenges posed by distributed systems, dynamic workloads, and hybrid architectures.

Key Benefits of API Observability:

• Enhanced Visibility: Provides insights into every API call, endpoint, and interaction.
• Real-Time Threat Detection: Identifies anomalies and potential threats instantly.
• Improved Compliance: Tracks sensitive data flows to ensure regulatory adherence.
• Optimized Performance: Monitors API performance metrics to prevent downtime.

Case Studies: API Observability in Action

1. Securing Multi-Cloud Environments for a Healthcare Provider: A leading healthcare provider relied on Rakuten SixthSense to monitor 300K API calls across AWS and Azure platforms. By leveraging API observability tools, the organization detected 10 critical vulnerabilities, mitigated sensitive data exposures, and ensured HIPAA compliance. This enhanced visibility into API interactions helped secure patient data and support telemedicine services.

2. Protecting a Public Health System: A government health department used Rakuten SixthSense to secure 500K API calls. The platform’s observability features identified 30 instances of sensitive data exposure, enabling swift remediation and ensuring public trust.

Why Cloud Environments Demand Advanced API Observability

Cloud infrastructures introduce unique complexities, including:

• Dynamic Workloads: APIs in cloud systems are constantly created, updated, or deprecated, making it challenging to maintain visibility.
• Cross-Region Data Flow: APIs often transmit sensitive data across multiple geographies, increasing compliance risks.
• Multi-Tenant Architectures: Shared environments heighten the risk of data leaks and unauthorized access.

Rakuten SixthSense Advantage:

• Real-Time Monitoring: Tracks API activity across cloud environments to detect anomalies instantly.
• Sensitive Data Tracking: Ensures secure handling of PII and financial information across regions.
• Seamless Integration: Works with major cloud providers, including AWS, Azure, and Google Cloud, to deliver consistent security.

Industry Insights: High-Profile API Breaches in the Cloud Era

Recent years have seen several high-profile API breaches linked to cloud environments:

• A global financial services firm: Suffered significant losses when attackers exploited unsecured cloud APIs to access sensitive transaction data. Rakuten SixthSense’s real-time observability and anomaly detection could have prevented this breach by identifying unauthorized access early.
• A SaaS company: Faced a data breach exposing client credentials due to shadow APIs in their cloud ecosystem. With Rakuten SixthSense’s automated API discovery and inventory tools, such unmonitored endpoints would have been identified and secured proactively.

Key Features of Rakuten SixthSense API Observability
