The API security market has matured beyond traditional firewalls. In 2026, with the rise of sophisticated attacks and the use of Generative AI, organizations seek tools that not only block threats but also ensure application performance.
Let’s examine real cases where results were measurable with operational cost reductions, lower transaction latency, and successful security after implementing WAF and Firewall policies.
This guide analyzes tool categories, key selection criteria, and how vendors differentiate in the cybersecurity ecosystem.
API Security Tool Categories
Before choosing a vendor, it’s essential to understand that API security is divided into three main pillars:
WAAP (Web Application and API Protection)
Solutions that combine WAF, DDoS attack mitigation, Bot Management, and API security.
Advantage: Real-time protection in distributed architecture, blocking attacks before they reach your data center.
When to choose WAAP:
- Your organization needs protection against OWASP Top 10 and zero-day vulnerabilities
- You require unified visibility across web applications and APIs
- Latency is critical for user experience
API Gateways with Security Focus
Tools primarily designed for traffic management, but offering authentication and rate limiting modules.
Advantage: Granular control of internal policies, but typically lacking advanced protection against semantic or behavioral threats.
When to choose API Gateway:
- You need centralized token management (OAuth2/JWT)
- The focus is on microservices routing and payload transformations
- Your team already has runtime security expertise
Discovery and Testing Tools (SAST/DAST)
Focused on finding Shadow APIs and code vulnerabilities during development.
Advantage: Essential for the secure development lifecycle (SDLC).
When to choose Discovery:
- You need to map undocumented endpoints
- The goal is shift-left security in CI/CD pipeline
- Your organization already has runtime protection implemented
How to Evaluate API Security Vendors
When analyzing API security vendors, use the following criteria to ensure the solution meets 2026 demands:
1. Latency and Performance
Centralized solutions add 50-200ms per request. Look for a vendor that offers a platform that processes security in a distributed architecture (with p95 < 10ms), eliminating round-trips to origin.
Question for vendor: What is the p95 latency added per security request?
2. Bot Mitigation Capability
Can the vendor differentiate a malicious bot from a legitimate third-party integrator? For example, protecting card transactions without impacting legitimate customers.
Question for vendor: How does the solution differentiate legitimate automated traffic from attacks?
3. OWASP Top 10 Support
Does the solution offer pre-configured rules for the latest risks, including the OWASP Top 10 for LLMs?
Question for vendor: How many OWASP Top 10 API Security rules are covered by default?
4. Shadow API Visibility
Can the tool discover endpoints that weren’t documented by your team?
Question for vendor: Does the solution offer automatic and continuous API discovery?
5. Code-Based Automation
Does the solution allow configuration via API or “Security as Code” to integrate with your CI/CD pipeline?
Question for vendor: Does the platform offer a complete API for policy automation?
WAAP vs. API Gateway: Which to Choose?
Many companies make the mistake of believing that an API Gateway is sufficient for security.
Use an API Gateway for:
- Token management (OAuth2/JWT)
- Microservices routing
- Simple payload transformations
- Basic rate limiting
Use a WAAP Solution in Distributed Architecture for:
- SQL/NoSQL injection blocking
- Denial of service (DoS) attack protection
- Behavioral anomaly detection
- JSON Schema contract validation at global scale
- Sophisticated bot mitigation
Architecture Comparison:
| Criteria | WAAP | Traditional API Gateway |
|---|---|---|
| p95 Latency | < 10ms | 15-50ms |
| OWASP Top 10 Protection | ✅ Native | ⚠️ Requires plugins |
| DDoS Mitigation | ✅ Global | ❌ Limited |
| Cold starts | Zero | Variable |
| Custom rules via Functions | ✅ Unlimited | ⚠️ Limited |

When Zoop, iFood’s fintech, migrated their API security to Azion Web Platform, results were measurable: 30% reduction in operational costs, 50% lower transaction latency, and zero successful violations after implementing WAF and Firewall policies. Zoop achieved 99.99% uptime even during transaction peaks.
Zoop, a fintech specialized in payments, faced critical challenges:
Challenges:
- Protect card transactions against attacks and abuse
- Reduce bandwidth and infrastructure costs
- Ensure low latency for payment confirmations
Solution: Zoop adopted Azion Web Platform with WAF, Firewall, Network Shield, and Data Stream, integrating fraud intelligence via Azion Marketplace.
Results:
- 30% operational cost reduction
- 50% lower latency in transaction processing
- Zero successful violations after implementation
- 99.99% uptime even during demand peaks
- Real-time visibility via Data Stream for policy adjustment
Recommended Security Architecture for 2026
In 2026, API security requires an integrated approach that combines:
Essential Capabilities
- Runtime protection (WAAP) for real-time threat mitigation
- Code-based automation for integration with development pipelines
- Shadow API detection to ensure all endpoints are monitored
- Bot mitigation for protection against automated attacks

Frequently Asked Questions
1. What is WAAP and how does it differ from an API Gateway?
WAAP (Web Application and API Protection) is a comprehensive solution that combines WAF, DDoS mitigation, Bot Management, and API security in a single platform. An API Gateway is primarily focused on traffic management and authentication, without the advanced threat mitigation capabilities that a WAAP offers.
2. What are the main criteria for choosing an API security vendor?
The main criteria include latency and performance (p95 < 10ms), bot mitigation capability, OWASP Top 10 support, Shadow API visibility, and code-based automation. Zoop, for example, achieved 50% lower latency and 30% cost reduction by choosing Azion Web Platform.
3. Why is runtime protection important for API security?
Runtime protection is crucial because it allows threats to be blocked before they reach the backend, protecting data center resources and ensuring application availability. Companies like Zoop maintained 99.99% uptime even during transaction peaks.
4. How does Azion Web Platform differentiate from other API security vendors?
Azion Web Platform differentiates by offering a WAAP solution that combines advanced protection with unmatched performance (p95 < 10ms), while allowing the creation of custom security rules via Functions without cold starts, providing flexibility and total control over API security.
5. What are Shadow APIs and why is it important to detect them?
Shadow APIs are endpoints that haven’t been documented or monitored by the development team. Detecting them is important because they can be vulnerable to attacks and represent a significant security risk if not properly protected. Discovery tools and modern WAAPs offer automatic detection of these endpoints.
