How safe are your applications? In recent years, the significance of API (Application Programming Interface) usage and hence of API security has skyrocketed. According to Vanson Bourne's recent survey, 98% of enterprise leaders believe that APIs are an essential part of their organization’s digital transformation, and 97 percent agree that successfully executing an API strategy is essential to secure organizations’ future revenue and growth.
The financial impact of the API security breaches can be immense: in November 2023, crypto firm Kronos Research said $26 million worth of cryptocurrency was stolen from its systems following a cyber attack. The company said that it experienced “unauthorized access” to some of its API keys, forcing it to pause trading and begin an investigation.
More than that, a recent update of the OWASP Top 10 vulnerabilities for 2023 shows that threats are constantly evolving, and technologies behind the API security tools that you use for vulnerability management in your applications must progress with these changes.
In this article, we've prepared for you the selection of the best API security tools to help you protect your applications. We'll not only provide the description of each API security tool but also outline the pros and cons to help you make the best judgment. Let's dive right in!
Why is API Security important?
API security is crucial because it protects the integrity of your data and services. APIs, being the connecting threads between different software applications, are vulnerable to attacks. Ensuring their security means protecting your application's core functions and the sensitive data they handle.
According to Derek Fisher in the Elephant in AppSec podcast, "mindset we all in the security space need to have: assume that everybody within your network or within your system is adversarial".
You have to model all possible threats to your APIs and integrate the action plan into your Application Security program to strengthen your organizational API security posture.

Features of the best API security tools
When it comes to keeping your APIs safe, you need a good API security solution. Let's examine the main features that make the best API security tools special.
API Discovery & Inventory
Don’t know what your developers expose online? Here is when API Discovery and Inventory come into play. Every undocumented API feels like a ticking time bomb, a potential gateway for malicious breaches.
To ensure that the organization's data and services remain protected and bridge the gap between innovation and security, your top priority is to create a comprehensive inventory of all used APIs.
Need more information about API discovery? Check out here why API discovery is important and what is the difference between automated and manual approaches.
Automated API Discovery tools are indispensable to ensure efficiency, accuracy, and comprehensive coverage. Manual discovery should be seen as a complementary approach rather than a primary method in modern API management.
CI/CD Pipeline Integration
If you want to catch and fix security issues early in your development process, you must integrate security within your CI/CD pipeline. It helps you ensure your applications are built securely from the ground up and helps your organization to shift left testing of APIs.
Custom security tests
Each organization's API stack and their structure are not the same. You, as a security engineer, sometimes need to be able to write or extend your automated security tests to find vulnerabilities specific to your APIs. This can be particularly useful for running static security assessments on your web applications, identifying regression bugs, or investigating specialized in-house security concerns.
Support in remediation
Tired of struggling to get developers on board with security in the SDLC? Making life easier for your developers is important to ensure swift security fixes. Detailed remediation code snippets help to break down complex security issues into simple, actionable steps, so your developers can quickly fix any problems that pop up.
Ease of deployment
No one wants a complicated setup process. The faster you can start scanning, the faster you can protect your organization. Agentless solutions are your best bet: An agentless deployment method involves gathering data without the need to alter application code and without inserting any agents into the application's communication path.
No fuss, just quick and efficient protection.
Testing undocumented APIs
Hidden vulnerabilities can be a big risk. Testing undocumented APIs is important to find those hidden weaknesses and keep your data safe from potential threats.
Contextual risk-based prioritization
Prioritizing security tasks is vital. Contextual Risk-Based Prioritization is a strategy used in risk management and security to determine the priority of addressing vulnerabilities or threats based on their potential impact and context within a specific environment.
It helps you focus on what's most important first for your business, making sure you're putting your efforts where they matter the most.

Stackhawk is a DAST tool that scans APIs for potential vulnerabilities. Stackhawk is built on top of OWASP ZAP and works by simulating an attack, which is based on common open-source vulnerabilities like OWASP top 10 or custom attack definitions, and observing how the API responds. In other words, it tries to leverage known vulnerabilities on the API to observe how it reacts to them to determine if the API is secure against the vulnerability or not.
Stackhawk provides integration with your CI/CD so that you can automate the testing of every API endpoint in your application.
Stackhawk balances ease of deployment with advanced risk-based prioritization. Offers an intuitive dashboard for monitoring and responding to threats.
- Easy setup for smaller teams or organizations with good pricing options to get started.
- The risk assessment tool is user-friendly for security engineers with developer backgrounds.
- Supports a large number of integrations.
- Tests various API types.
- You are required to install HawkScan in your local environment via Homebrew. Local installations tie API security to individual devices. If someone leaves the team or changes their device, it may disrupt the scanning process and compromise security continuity. More than that, requiring multiple team members to install the tool individually can lead to inconsistencies in the security posture and become a barrier to collaboration, as the process is not streamlined.
- Lacks an on-prem solution required by some industries and organizations.
- Lack of API discovery & inventory, which could be a limitation for larger organizations with complex API ecosystems.
- StackHawk scan results payload is organized as a list of every unique finding across the scan. It provides information about vulnerability, risk, confidence, paths and may include OWASP Cheatsheet, but does not offer detailed remediation code snippets for developers.
- StackHawk's prioritization is based on the OWASP Risk Rating Methodology. The OWASP Risk Rating Methodology primarily focuses on the technical aspects of security issues, such as their impact and exploitability. It may not take into account the specific context of your application, its users, or your business objectives.
