Large enterprises account for a larger share of the WAF market compared to small and medium-sized businesses (SMBs), leveraging their resources to deploy comprehensive WAF solutions across complex, high-traffic web environments. However, SMBs are increasingly adopting cloud-based WAFs due to their affordability, scalability, and ease of deployment, contributing to market growth as digital services become more accessible to smaller organizations.

Common Vulnerabilities for Web Applications

Web applications and APIs are prime targets for attackers due to their accessibility and the sensitive data they handle. The OWASP Top 10 Web Application Security Risks (as of March 2025) provides a critical framework for understanding these vulnerabilities, which WAFs are designed to mitigate:

1. Broken Access Control: Failure to enforce proper access controls, allowing unauthorized users to access restricted resources.
2. Cryptographic Failures: Weak encryption or improper handling of sensitive data, leading to data exposure.
3. Injection: Attacks like SQL injection, where malicious code is inserted into application inputs to manipulate databases or systems.
4. Insecure Design: Flaws in application architecture that create exploitable vulnerabilities.
5. Security Misconfiguration: Improperly configured servers, frameworks, or applications that expose vulnerabilities.
6. Vulnerable and Outdated Components: Use of outdated libraries, frameworks, or software with known vulnerabilities.
7. Identification and Authentication Failures: Weak authentication mechanisms that allow attackers to impersonate legitimate users.
8. Software and Data Integrity Failures: Lack of integrity checks, enabling attackers to manipulate software or data.
9. Security Logging and Monitoring Failures: Inadequate logging or monitoring, hindering detection and response to attacks.
10. Server-Side Request Forgery (SSRF): Attacks that trick servers into making unauthorized requests to internal or external resources.

WAFs play a critical role in addressing these vulnerabilities by filtering malicious traffic, enforcing security policies, and providing real-time monitoring to detect and block attacks before they reach the application layer.

Network Attack Trends and Statistics

The growing sophistication and volume of web-based attacks highlight the importance of WAFs in modern cybersecurity strategies. Key statistics from industry reports provide insight into the threat landscape:

• Bot Traffic According to a study from Akamai, bots account for nearly 42% of all internet traffic, with 65% of these bots being malicious. While benign bots (e.g., search engine crawlers, SEO tools, and social media bots) serve legitimate purposes, malicious bots pose significant risks. Of the malicious bot traffic detected, 47.6% was generated by advanced scripted botnets, making them the most common source of automated attacks. These botnets are often used for credential stuffing, data scraping, and DDoS attacks, underscoring the need for WAFs with advanced bot detection and mitigation capabilities.
  
• API Attacks: APIs are increasingly targeted due to their role in connecting applications and services. Akamai reported that 29% of web attacks over a 12-month period targeted APIs, with nearly one-third of suspicious bot requests globally aimed at APIs. As APIs become more prevalent in cloud-native and microservices architectures, WAFs must evolve to provide specialized protection, including API-specific rules and rate-limiting to prevent abuse.
  
• DDoS Attacks: DDoS attacks remain a significant threat, with approximately 512,000 DDoS attacks recorded worldwide in Q4 2024. The gaming industry was the most targeted, accounting for 34% of attacks, followed by financial services (26%) and technology (19%). WAFs with DDoS mitigation capabilities, such as rate-limiting and traffic filtering, are critical for protecting web applications from these disruptive attacks.
