Best Application Security Tools 2025

What are Application Security Tools?

Application Security Tools are designed to protect software applications from external threats throughout the entire application lifecycle. Enterprise applications sometimes contain vulnerabilities that can be exploited by bad actors. The purpose of this class of tools is to protect the many different kinds of application against data theft or other nefarious intent. These include legacy, desktop, cloud, and mobile apps used by internal employees, partners, and customers. Modern application security solutions must cover the gamut of application types and provide security testing that is easy to use and deploy.

Products in this category are distinguished by their focus on securing systems at the application layer, vs. protecting attack surfaces like networks. Beyond that, there is a wide range of processes that fall under application security. The two most prevalent functions include testing or applications for vulnerabilities, or remediating threats once they’ve been identified. Some products will take on both functions, but many will specialize into one or the other. Application security can also be enhanced by creating a security profile for each application that identifies and prioritizes potential threats and documenting actions taken to counter malicious or unplanned events.

Since application security is so broad a space, there are a number of specialized categories that have emerged. The most commonly used categories of application security tools include:

• Vulnerability management, which can be used during development or on in-production applications
• Application security testing tools, such as Dynamic testing, Static testing, and Interactive testing, which are used during application development
• Penetration testing, which is most often used on in-production applications as part of a broader security assessment

Each of these types of security tools serve different purposes, so they are often used complimentarily. Business-critical applications or those with sensitive data may use many, or all, of these tools throughout the application’s lifecycle.

Application Security Tools Features

Many different types of application security tools can be found here. Some of the most common and necessary features of application security tools include:

• Source code analysis/scanning
• Open source component monitoring
• Vulnerability detection
• Optimized vulnerability remediation
• Integration with source code repositories, build management server, bug tracking tools and major IDEs
• Training resources to sharpen developer security skills

Application Security Tools Comparison

When comparing application security tools, consider these factors:

• Open Source vs. Paid Tools: Does the organization have in-house expertise and resourcing to handle application security? If so, open source tools can be an effective and cost-efficient approach to some application security. However, paid options will likely become necessary for scalability and internal resource constraints in the long term.
• Security Type: How specifically do the applications in question need to be secured. Are you looking for security tools to use during development, or to secure apps that are already in production? Often, the answer will eventually become “all of the above.” In this case, a suite of application security tools will likely be the most productive.
• Integrations: How well does each tool integrate with existing developer environments, network security tools, or other application security tools in use? Modern security systems need to be able to efficiently communicate, share, and use data from each other. Well-integrated systems can pay massive dividends in terms of manual maintenance requirements and response times in the event of a security event.

Pricing Details

Pricing varies widely depending on whether the product is a cloud-based solution, cloud + professional services, or an on-premises tool. In general though, application security platforms price by the number of applications or volume of the codebase in question. Pricing per application can range in the thousands of dollars, or hundreds of dollars per thousand lines of code.

There are also a number of open source application security tools. These tools are free to download and use, but often come with optional paid services, like implementation and support.
