APIs now power everything — from mobile apps and cloud-native platforms to financial transactions and IoT devices. But as organizations expose more APIs, attackers are finding new ways to exploit them. The OWASP API Security Top 10 (2023) serves as the industry’s most trusted guide to understanding these risks and strengthening API defenses.

The latest list highlights critical vulnerabilities such as Broken Object Level Authorization (BOLA), Broken Authentication, Unrestricted Resource Consumption, Security Misconfiguration, and Unsafe Consumption of APIs. Each of these weaknesses can lead to serious consequences — including data leaks, unauthorized access, and full-scale breaches. According to recent reports, over 61% of API-related attacks are authentication-based, making identity protection a top priority.

Modern API security requires more than gateways and tokens — it demands identity-first architecture and real-time visibility into every machine-to-machine interaction. That’s where Corsha delivers value. By applying multi-factor authentication (MFA) for every API request, Corsha brings Zero Trust principles to API communication. Its behavioral analytics, dynamic policy enforcement, and automated credential rotation help protect against key OWASP vulnerabilities like Broken Auth, BOLA, and Improper Inventory Management.

As APIs become the new attack surface, frameworks like OWASP’s are essential for securing today’s digital ecosystems. OWASP’s upcoming 2025 API Security update is expected to emphasize continuous authentication, runtime security, and AI-driven anomaly detection — all vital for defending against evolving threats.

In short, protecting APIs starts with visibility, identity assurance, and Zero Trust enforcement. With the OWASP API Top 10 as your foundation and solutions like Corsha as your guardrail, organizations can finally secure the connections that power modern business.
