Critical data on how rate limiting protects enterprise APIs from attacks, ensures system stability, and supports compliance in an era of unprecedented API growth
API traffic now dominates internet activity, yet a startling 85% of APIs operate without rate limiting—leaving organizations exposed to DDoS attacks, credential stuffing, and resource exhaustion. DreamFactory's enterprise security controls address this vulnerability through built-in, role-based rate limiting that requires zero custom code. With the API rate limiting market projected to reach $6.89 billion by 2033 and API attacks surging across every industry, these 45 statistics reveal why rate limiting has become non-negotiable for enterprise security strategy.

The Evolving Threat Landscape: Why API Security Matters More Than Ever
1. 99% of organizations encountered API security issues in the past 12 months
The Salt Labs State Report reveals that virtually every organization experienced API security problems, up from 94% in 2022. This near-universal vulnerability demonstrates why proactive security measures like rate limiting are essential infrastructure.
2. APIs faced 166% higher DDoS attacks than websites
APIs have become the primary attack target, experiencing 166% more DDoS attacks than traditional websites according to the Indusface State of Application Security 2025 report.
3. DDoS attacks against APIs surged 94% year-over-year
The 94% year-over-year increase in API-focused DDoS attacks reflects attackers' strategic shift toward API endpoints as the weakest point in enterprise infrastructure.
4. 7.7+ billion cyberattacks blocked in 2024
Organizations blocked 7.7 billion attacks across websites and APIs in 2024—a volume that demands automated protection mechanisms rather than manual monitoring.
5. Bot attacks rose 48% from Q1 to Q4 2024
Bot-driven attacks increased 48% throughout 2024, reaching 765+ million total. Rate limiting provides the first line of defense against automated attack patterns.

Perhaps most concerning, 95% of attacks originate from authenticated sessions, proving that authentication alone cannot secure APIs. Rate limiting applies throttling even to authenticated users, preventing abuse after credential compromise.
7. 46% of account takeover attacks target API endpoints
Nearly half of all account takeover attempts now focus on APIs, making rate limiting critical for protecting authentication endpoints from credential stuffing attacks.
API Rate Limiting: A Foundational Layer of API Security
8. Only 15% of APIs implement rate limiting
Despite the threat landscape, just 15% of APIs have implemented rate limiting, leaving the vast majority vulnerable to resource exhaustion and abuse.
9. 85% of APIs don't use rate limiting
Analysis confirms that 85% of production APIs operate without any rate limiting controls—a critical gap that attackers exploit daily. DreamFactory's security layer includes rate limiting configurable per role, addressing this vulnerability without custom development.
10. 40% of API integrations fail due to unhandled rate limits
Beyond security, 40% of integration failures stem from improperly handled rate limits—causing business disruption when APIs throttle requests unexpectedly.
11. 29% of API security incidents relate to authentication failures
Authentication failures account for 29% of security incidents. Rate limiting on authentication endpoints prevents brute-force attacks that exploit these weaknesses.
12. 37% of security issues stem from misconfigurations
API misconfigurations cause 37% of security issues. Configuration-driven platforms like DreamFactory reduce misconfiguration risk by enforcing security policies at the platform level rather than relying on developer implementation.
13. 51% cite unauthorized API calls from AI agents as top security concern
With AI adoption accelerating, 51% of developers identify unauthorized AI agent API calls as their primary security concern. Rate limiting provides essential throttling for AI-driven traffic patterns.
