How API Observability
Enhances Threat Detection
in Real-Time

In today’s hyperconnected world, APIs are essential for powering digital ecosystems. From enabling seamless data exchange to supporting complex microservices architectures, APIs are at the core of modern business operations. However, with increased reliance on APIs comes a greater risk of cyber threats. Real-time threat detection has become a necessity, and API observability plays a pivotal role in ensuring the security and resilience of digital infrastructures.

API observability empowers organizations to monitor and analyze API traffic in real time, detecting anomalies and mitigating risks before they escalate. In this blog, we’ll explore how API observability enhances threat detection and how Rakuten SixthSense offers innovative solutions to protect APIs and maintain business continuity.

The Importance of Real-Time Threat Detection

Rising API Threats

APIs have become prime targets for attackers due to their critical role in data exchange. Common threats include bot attacks, data exfiltration, and API abuse. In 2022, a major security breach exposed millions of user records due to an unsecured API endpoint. Such incidents highlight the urgent need for real-time monitoring and observability.

Real-time API monitoring enables organizations to detect and respond to threats as they happen, preventing significant data loss and operational disruptions.

Key Challenges Addressed by Real-Time Observability

• Delayed Response Times: Traditional security approaches often detect issues after the damage is done.
• Lack of Visibility: Complex API ecosystems can obscure potential vulnerabilities.
• Regulatory Compliance Risks: Failure to detect and address threats can lead to non-compliance with regulations like GDPR and PCI DSS.

How API Observability Works

API observability provides comprehensive insights into API ecosystems by continuously monitoring traffic, identifying anomalies, and ensuring compliance. It encompasses three core capabilities:

1. Real-Time Monitoring

Real-time monitoring tracks API traffic and behavior, identifying deviations from normal patterns.

Rakuten SixthSense Solution:

• Behavioral analytics: Detect unusual API usage.
• Dynamic dashboards: Provide actionable insights to optimize security and performance.

2. Vulnerability Management

Proactive vulnerability management identifies and addresses security gaps before they are exploited.

Example: Rakuten SixthSense enabled a global financial institution to detect and mitigate 50 critical vulnerabilities in its API ecosystem, ensuring robust protection and regulatory compliance.

3. Automated Threat Response

Automated responses, such as virtual patching and rate limiting, mitigate threats in real time without disrupting operations.

Benefits of API Observability in Threat Detection

• Early Detection of Anomalies: API observability tools flag unusual activity, such as unauthorized access attempts or abnormal traffic spikes, allowing teams to act swiftly.
• Enhanced Security Posture: Comprehensive visibility into API interactions ensures that vulnerabilities are identified and addressed proactively, reducing the risk of data breaches.
• Compliance Assurance: Automated monitoring and reporting streamline adherence to regulations, minimizing compliance risks.
• Operational Resilience: Real-time monitoring and threat detection minimize downtime, ensuring uninterrupted service delivery.
