What is Application Security Software for Linux?
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. Compare and read user reviews of the best Application Security software for Linux currently available using the table below. This list is updated regularly.

GitGuardian
GitGuardian
GitGuardian is an end-to-end NHI security platform that empowers software-driven organizations to enhance their Non-Human Identity (NHI) security and comply with industry standards. With attackers increasingly targeting NHIs, such as service accounts and applications, GitGuardian integrates Secrets Security and NHI Governance. This dual approach enables the detection of compromised secrets across your dev environments while also managing non human identities and their secrets lifecycle. The platform supports over 450+ types of secrets, offers public monitoring for leaked data, and deploys honeytokens for added defense. Trusted by over 600,000 developers, GitGuardian is the choice of leading organizations like Snowflake, ING, BASF and Bouygues Telecom for robust secrets protection.Starting Price: $0 -

Jit
Jit
DevOps ain’t easy! We are hearing more and more about the breakdown and friction where Dev meets Ops, so let’s not even talk about all the other shift-left domains that add another layer of complexity in the middle like DevSecOps. Where this comes with the need to implement and integrate dozens of security tools in their SDLC. But what if it doesn’t have to be difficult? Jit's DevSecOps Orchestration Platform allows high-velocity Engineering teams to own product security while increasing dev velocity. With a unified and friendly developer experience, we envision a world where every cloud application is born with Minimal Viable Security (MVS) embedded and iteratively improves by adding Continuous Security into CI/CD/CS. -

SecureStack
SecureStack
With triggers in your CI/CD pipeline, SecureStack can check for common security issues and stop those issues from getting into your applications. SecureStack embeds security automatically with every git push. We built our technology to test every facet of your application security looking for things like missing security controls, are you using encryption correctly; we test the efficacy of your WAF and are your cloud-native components secure and more than 250 other data points. All of that was delivered in less than 60 seconds. See what a hacker can see when they view your applications. Test and compare your development, staging and production environments to quickly find critical differences and understand ways to fix high-priority defects. We help you decompose your web application so you are aware of all the resources your app is using behind the scenes.Starting Price: $500/mo -

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 -

Phylum
Phylum
Phylum defends applications at the perimeter of the open-source ecosystem and the tools used to build software. Its automated analysis engine scans third-party code as soon as it’s published into the open-source ecosystem to vet software packages, identify risks, inform users and block attacks. Think of Phylum like a firewall for open-source code. Phylum’s database of open-source software supply chain risks is the most comprehensive and scalable offering available, and can be deployed throughout the development lifecycle depending on an organization’s infrastructure and appsec program maturity: in front of artifact repository managers, directly with package managers or in CI/CD pipelines. The Phylum policy library allows users to toggle on the blocking of critical vulnerabilities, attacks like typosquats, obfuscated code and dependency confusion, copyleft licenses, and more. Users can also leverage OPA to create custom policies.
