Wallarm’s Security Edge is setting a new standard in API security—far beyond the reach of traditional Content Delivery Networks (CDNs). Let’s get it straight: Security Edge is not just a new addition to the API security market; it’s a disruption. Designed to deliver fast, effective, and advanced API protection where APIs need it, Wallarm’s Security Edge targets what CDNs cannot. It’s time to face reality—CDNs have been a cornerstone of the digital era, but they are rapidly falling behind in the API age.

In this blog, we’ll explain why Security Edge represents a major leap in capability, why CDNs can’t keep up, and how Wallarm’s approach could reshape the landscape of edge security.

Why Are You Sending API Traffic Through a CDN?

CDNs were a game-changer for web applications in the early 2000s, optimizing content delivery for web pages. Their ability to geographically distribute cached content close to the consumers of that content is foundational for web applications. But APIs are different—they’re dynamic and carry sensitive data, connect microservices, and power mobile apps that demand real-time interactions. CDNs, designed to cache static content, lack the adaptive intelligence and real-time processing capabilities needed for effective API security. A CDN can cache your website, but when it comes to securing complex API traffic, it’s like trying to use a bicycle to keep up with a racecar.

CDNs generally offer basic security features, like DDoS protection and some bot mitigation, but these are often insufficient for API traffic, where threats are nuanced and can bypass simple filters. Wallarm’s Security Edge, in contrast, has a dynamic approach to security that detects and blocks API-specific attacks, including those targeting business logic or attempting to misuse sensitive functions within an API.

What Sets Security Edge Apart?

Wallarm’s Security Edge is a high-powered, cloud-native security solution with true “API edge” deployment. At its core, it offers inline protection for APIs, positioning it at the point where APIs access and process data. Security Edge is still geographically distributed but optimized for APIs, not delivery of cached content. This “API edge” deployment is crucial because it minimizes latency—a critical requirement for APIs that power apps, websites, and data-driven services across industries.

Another key differentiator for Security Edge is its deep API-specific protection, covering everything from OWASP Top 10 vulnerabilities to complex API logic abuses. While useful for static content caching, traditional CDN-based WAFs (Web Application Firewalls) struggle to apply these API-specific rules. Security Edge brings dynamic, adaptive threat detection to the API edge, and with this capability, it neutralizes API threats in real time.

CDNs primarily focus on static content and cache management, meaning their security is not built for the API traffic that now dominates modern applications. Security Edge, however, dives deep into inspecting each API call to detect attacks like excessive data exposure or rate-limiting issues, which are too complex for CDNs to handle effectively. With Wallarm, enterprises can ensure their API traffic is secured down to each transaction.

Security Edge: The New Standard for API Protection

With Wallarm’s Security Edge, businesses get a powerful tool built explicitly for APIs. Here’s how Wallarm is rethinking API security:

1. Intelligent, Real-Time Threat Detection: Unlike CDNs, which are inherently reactive, Security Edge uses machine learning to detect and prevent threats in real time. It can immediately detect abnormal patterns and block potential attacks as they happen. This is critical for modern applications, where speed and agility are paramount. CDNs cannot offer this granularity in security.
2. Comprehensive API Exploit Coverage: Security Edge protects against vulnerabilities in APIs that CDNs can’t touch, including injection attacks, data leakage, and rate-limiting violations. It’s all-encompassing protection that includes automated detection of misconfigured APIs. This coverage ensures no aspect of API security is left to chance, while CDNs are limited in scope and lack the flexibility to secure complex API architectures.
3. Edge-Powered API Analytics: Security Edge doesn’t just block attacks—it provides rich analytics and insights that allow companies to understand where they are vulnerable and how threats evolve over time. This intelligence is invaluable in a world where attackers constantly adapt, and API security threats grow more complex. With real-time analytics from Security Edge, security teams are better equipped to respond and fortify their API protection, something CDNs simply cannot offer.

The Takeaway: Wallarm Security Edge Is the Future

Wallarm’s Security Edge is more than a product; it’s a shift in how we think about API security. CDNs served us well for a time, but they are tools of the past. Wallarm’s edge-based approach brings security where needed most—at the heart of data flow. By delivering API-specific threat detection, deep inspection, and real-time protection, Wallarm’s Security Edge sets a new standard for API security and fills a critical gap that CDNs can’t.

The choice for companies serious about security is clear: Security Edge offers a comprehensive, powerful solution that aligns with the modern demands of API-driven business. For CDNs, the future looks uncertain. Wallarm has introduced a solution that is not just necessary but essential, and as more organizations adopt API-first strategies, Security Edge is poised to lead the way.
