What is Free Application Security Software?
Application security software is designed to protect applications from cyber threats by identifying vulnerabilities, preventing attacks, and ensuring data integrity throughout the application’s lifecycle. This software typically includes features like static and dynamic analysis, runtime protection, and vulnerability scanning to detect and address potential security issues such as SQL injection, cross-site scripting (XSS), and unauthorized access. It helps organizations maintain secure applications by implementing best practices for secure coding, performing penetration testing, and monitoring for security breaches. Application security software is crucial for organizations to safeguard sensitive data, comply with regulations, and minimize the risk of exploitation.

Contrast Security
Contrast Security
Modern software development must match the speed of the business. But the modern AppSec tool soup lacks integration and creates complexity that slows software development life cycles. Contrast simplifies the complexity that impedes today’s development teams. Legacy AppSec employs a one-size-fits-all vulnerability detection and remediation approach that is inefficient and costly. Contrast automatically applies the best analysis and remediation technique, dramatically improving efficiencies and efficacy. Separate AppSec tools create silos that obfuscate the gathering of actionable intelligence across the application attack surface. Contrast delivers centralized observability that is critical to managing risks and capitalizing on operational efficiencies, both for security and development teams. Contrast Scan is pipeline native and delivers the speed, accuracy, and integration demanded by modern software development.Starting Price: $0 -
