What is WAAP? – A Quick Walk Through

Many of the businesses that already have revenue-generating web applications are starting an API-first program. Now, old monolithic apps are being broken into microservices developed in elastic and flexible service-mesh architecture.

The common question most organizations grapple with is – how to enhance application security designed for web apps to APIs and API security? 

Protecting APIs against modern cyber threats requires going beyond the traditional solutions. Web Application and API protection (WAAP), the next generation of Web Application Firewall (WAF) comes to the rescue.

What is WAAP? 

WAAP (Web Application and API Protection) is a set of cloud-based security services specially designed to protect web applications and APIs. This security tool is far more advanced than a WAF that mostly monitors OWASP application threats. This expanded WAF integrates, observes, and takes intuitive action when needed. With real-time logs and statistics, it can integrate well with other applications the company uses. 

WAAP Vs WAF

A Web Application Firewall (WAF) is designed to protect web applications by monitoring, filtering, and blocking unauthorized or malicious traffic. However, it primarily focuses on traditional web threats and lacks advanced API security capabilities.

WAAP (Web Application and API Protection) bundles WAF functionality with API security, bot mitigation, DDoS protection, and behavioral analytics, creating a unified, adaptive security model.

Transitioning from WAF to WAAP ensures a comprehensive, automated API security strategy. WAAP enhances protection with behavioral analysis, API discovery, advanced authentication, and AI-driven threat prevention, providing robust defense against modern web and API attacks.

Challenges in securing web applications and APIs

APIs are not insecure by nature, but due to the complexity and quantity of API adoption, it is easy to have security gaps and cyber risks waiting to leap out. Without proper functions, security testing, authentication checks, and input validation, APIs can become a perfect target. Hackers just need one loophole for a successful exploit. 

1. API Security Breaches are Piling Up

API attacks are escalating at an alarming rate. According to our State of Application Security Report, over 271 million API attacks were recorded in Q3 2024, with each API experiencing 3,000% more DDoS attacks compared to websites. On average, APIs faced 85% more attacks than traditional web applications, highlighting the increasing focus of attackers on API vulnerabilities.

APIs have emerged as a major attack vector, with numerous companies reporting API-related security breaches. For example, Peloton, a fitness company, exposed the data of three million customers due to a flawed API that allowed unauthorized access to private accounts. Similarly, Venmo, USPS’ Corporate Database, Facebook, and JustDial have all fallen victim to API security incidents.

These growing threats emphasize the urgent need for API-specific security solutions beyond traditional security tools like VLANs, firewalls, RASPs, and WAFs. As API threats continue to surge, organizations must adopt comprehensive API protection strategies to safeguard sensitive data and prevent large-scale breaches.

2. Traditional Security Solutions Are No Longer Enough

Enterprises must meet several requirements to maintain their web application and API protection levels. Unfortunately, the traditional security solutions that most enterprises usually deploy create problems rather than providing solutions.

False Negative Vulnerability Scanning

If you are using a general web application scanner to scan APIs, you are likely missing 8 out of 10 API vulnerabilities. Traditional scanners are designed for web applications and may not properly detect API-specific threats, leading to false negatives. This creates a false sense of security, as undetected vulnerabilities remain exploitable.

To accurately assess API security, organizations need API-focused vulnerability scanning tools that:

Support modern API architectures – including REST, GraphQL, and SOAP.

Scan API endpoints for authentication flaws, business logic abuses, and misconfigurations.

Identify OWASP API Top 10 vulnerabilities such as Broken Object Level Authorization (BOLA) and Excessive Data Exposure.

Simulate real-world API attacks to uncover hidden risks.

Indusface WAS – API Scanner ensures accurate API security by detecting shadow APIs and vulnerabilities from OWASP Top 10, SANS 25, zero-day exploits, and WASC classifications. With DAST augmented by human expertise, built-in manual penetration testing, and intelligent API scanning, it provides real-time security insights and comprehensive protection against evolving threats.

API Gateway Security Limit 
The API gateway provides various security functionalities for authenticating API users, rate limiting, audit trail, and ensuring compliance. Though it offers basic API protections, it leaves many opportunities for attackers. The API gateway concentrates only on the front door of the API. The security can be compromised by fake and compromised credentials.

Signature-based Solutions are Insufficient for API Security 
Signature-based approaches are based on the analysis of the previous attack. However, when a new attack happens, which does not match with the signature, the tools won’t stop it. Further, the signatures and static rules can’t prevent business logic attacks as the traffic looks legitimate. Broken Object Level Authorization (BOLA), this business logic vulnerability occupies the number one position in the OWASP Top 10 API Threats list. 

WAFs – Static Rules Fall Short 
WAFs (Web Application Firewalls) prevent attacks by allowing only safe traffic through the web applications. A Web Application Firewall is an important part of AppSec, but there are some limitations with its static rule-based protection. The continuous change in modern web apps and APIs requires manual tuning as well as rule development – making manual administration a prerequisite. 

Traditional WAFs that focus on the attacks originating from external traffic might leave the insider attacks undetected.

RASP (Runtime Application Self-Protection) – Patterns are Misleading 
The visibility of RASP is limited when it needs to be engaged with microservices at different endpoints. Though it stops the attack against these endpoints, it can’t detect actions across the entire service at once. In addition, as it does not learn the business context, it may predict a valid use case as an attempt to attack and stop it.

Demands Inspection of Encrypted Traffic 
While TLS encryption denies the ability of hackers to surveil the traffic, it makes the traffic content invisible to the firewall for inspection. It offers intruders a great way to hide anything they want to add to the stream using security technologies.

Core Capabilities of WAAP Solutions

As firewalls and other security solutions are no longer enough to fulfill the API security requirements, the way to address this situation is to adopt a consolidated platform called WAAP.  

WAAP evolved as a product suite and provides comprehensive security solutions for monolithic and microservice-based apps as well as APIs. It ensures protection against known and zero-day attacks with an integrated WAF, anti-DDoS, bot management, and API protection. 

WAAP: Core Capabilities

Fully Managed WAF (Web Application Firewall)

A fully managed, cloud-based WAF acts as the first line of defense for web applications and APIs, offering continuous monitoring, automated threat detection, and expert-managed security.

One of the primary actions that WAFs use to detect and prevent attacks is their ability to deny requests based on specific criteria.

For example, AppTrana WAF enhances security by leveraging reputation databases like Spamhaus DB and HoneyPot project to blacklist malicious IPs and block harmful requests. It also integrates geolocation-based blocking using MaxMind DB to restrict access from high-risk regions.

By analyzing app behavior and traffic patterns, the WAF establishes a baseline of normal activity and triggers defenses when anomalies occur. It protects against OWASP Top 10 threats, DDoS attacks, and advanced exploits such as SQL injection, XSS, file inclusion, buffer overflow, and cookie poisoning.

With AppTrana Managed WAF, security experts continuously monitor, analyze, and update security policies to defend against emerging threats, eliminating the need for in-house teams to manage complex configurations.

API Security

A robust API security strategy goes beyond basic protections like authentication and rate limiting. A robust API security strategy must include API discovery and a positive security model to detect and mitigate threats in real time. API discovery continuously scans environments to identify shadow APIs, deprecated endpoints, and active API traffic, ensuring complete visibility and enforcement of security policies. The positive security model takes a proactive approach by allowing only pre-approved API requests based on automated policy creation using Swagger files, effectively minimizing unauthorized access and business logic abuse.

Bot Mitigation and Management
Malicious botnets are a key tool for initiating an attack against an API. Bot mitigation capabilities block malicious bot activity while allowing bots that support legitimate business needs like search engines or performance and health monitoring tools. With seamless visibility as well as control over bot traffic, it protects websites, web applications, and APIs from automated traffic. 

DDoS Attack Protection
Anti-DDoS solutions secure on-premise as well as cloud-based assets no matter where they’re hosted (Microsoft Azure, AWS, or Google Cloud). WAAP ensures that its DDoS mitigation strategy is capable to detect and mitigate API-focused distributed denial of service attacks. It blocks traffic at the edge for seamless business continuity with no performance impact and guaranteed uptime.

Additional WAAP Capabilities

ML-Based Threat Detection
Signature-based detection contributes to many false positives. WAAP employs ML-based threat detection to defend against zero-day attacks with a minimum of false positives.

Real-Time Attack Analytics
The Web application and API protection tool offers complete visibility with domain expertise and employs ML techniques to monitor all security events and reveal attack patterns.

Automation And Orchestration
In addition to the core capabilities, web application and API protection solutions offer automation and enable orchestration across the entire infrastructure. Manually creating rules and rewriting policies can’t keep up with the pace of innovation. WAAP approach automates the flow of security events and empowers incident response workflows.

Adopting this unified solution can bring operational benefits through automated rule updates. The WAAP solution’s built-in intelligence enables it to learn independently and adapt to the ever-changing threat landscape.

Choosing The Right WAAP Solution

A Web Application Firewall (WAAP) is a critical component of any organization’s security infrastructure, designed to protect against a wide range of web application and API attacks.

While the importance of a WAAP cannot be understated, not all WAAPs are created equal. Therefore, evaluating and choosing the best WAAP for your organization is essential. To assist you in this process, we have prepared an informative article on cloud WAF pricing that highlights key considerations.

Here are some key factors to consider when evaluating WAAPs:

Security Effectiveness

The most important factor to consider when evaluating WAAPs is their security effectiveness. Look for a solution that provides comprehensive security features such as web application firewall, DDoS protection, bot protection, and vulnerability scanning.

A WAAP should be able to effectively identify and block all application and API attacks while allowing legitimate traffic. It should be able to detect zero-day vulnerabilities and continuously update its security rules to protect against new threats. To evaluate WAAP’s effectiveness, organizations should perform security testing against it using different attack scenarios to see how it responds.

Ease of Use

Another crucial factor to consider is the ease of use of the WAAP. The WAAP should be easy to configure, manage, and maintain. It should have a user-friendly interface allowing security teams to identify and respond to security incidents quickly. Moreover, it should integrate with other security tools and workflows so that security teams can streamline their processes and workflows.

Customization

Your web application and API are unique, and your security solution should reflect that. Look for a service that allows customization and configuration to meet your requirements. The service should also provide granular control over security policies and rules, allowing you to fine-tune the level of protection for different components of your application.

Reporting and Analytics

A good WAAP should provide detailed reports and analytics that help organizations to understand their web application traffic and identify potential vulnerabilities. WAAP should be able to provide actionable insights that allow security teams to prioritize their efforts effectively.

Compliance

A WAAP should be able to help organizations to comply with regulatory requirements such as the Payment Card Industry Data Security Standard (PCI-DSS), the General Data Protection Regulation (GDPR), and other security standards. It should provide features such as log retention, compliance reporting, and audit trials to help organizations demonstrate compliance.

AppTrana WAAP SwyftComply ensures compliance with security frameworks by providing a clean, zero-vulnerability report. It leverages autonomous patching to remediate vulnerabilities within 72 hours, minimizing security risks and ensuring continuous compliance. With log retention, real-time compliance reporting, and detailed audit trails, organizations can easily meet regulatory requirements while maintaining a strong security posture.

Cost

Organizations should choose a WAAP that provides the best value for their money. The cost of a WAAP should be proportional to its security effectiveness, scalability, and ease of use. Moreover, organizations should consider the total cost of ownership (TCO) of the WAAP, including acquisition, implementation, and maintenance costs.

Performance

Your security service should not impact the performance of your web application or API. Look for a solution that provides fast and efficient protection without affecting the response time of your application. The security solution should also be scalable to handle traffic spikes and increasing volumes of data.

Support and Maintenance

Look for a solution provider who provides 24/7 support and maintenance. They should offer regular updates and patches to protect against new security threats. The provider should also provide training and documentation to help you understand and configure the security settings.
