Best Application Security Software for Visual Studio Code

ZeroPath (YC S24) is an AI-native application security platform that delivers comprehensive code protection beyond traditional SAST. Founded by security engineers from Tesla and Google, ZeroPath combines large language models with deep program analysis to deliver intelligent security testing that finds real vulnerabilities while dramatically reducing false positives. Unlike traditional SAST tools that rely on pattern matching, ZeroPath understands code context, business logic, and developer intent. This enables identification of sophisticated security issues including business logic flaws, broken authentication, authorization bypasses, and complex dependency vulnerabilities. Our comprehensive security suite covers the application security lifecycle: 1. AI-powered SAST 2. Software Composition Analysis with reachability analysis 3. Secrets detection and validation 4. Infrastructure as Code scanning 5. Automated PR reviews 6. Automated patch generation and more... ZeroPath integrates seamlessly with GitHub, GitLab, Bitbucket, Azure DevOps and many more. The platform handles codebases with millions of lines across Python, JavaScript, TypeScript, Java, Go, Ruby, Rust, PHP, Kotlin and more. Our research team has been successful in finding vulnerabilities like critical account takeover in better-auth (CVE-2025-61928, 300k+ weekly downloads), identifying 170+ verified bugs in curl, and discovering 0-days in production systems at Netflix, Hulu, and Salesforce. Trusted by 750+ companies and performing 200k+ code scans monthly.

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.

Modern software development must be as fast as the business. The modern AppSec toolbox lacks integration, which creates complexity that slows down software development life cycles. Contrast reduces the complexity that hinders today's development teams. Legacy AppSec uses a single-size-fits all approach to vulnerability detection and remediation that is inefficient, costly, and expensive. Contrast automatically applies the most efficient analysis and remediation technique, greatly improving efficiency and effectiveness. Separate AppSec tools can create silos that hinder the collection of actionable intelligence across an application attack surface. Contrast provides centralized observability, which is crucial for managing risks and capitalizing upon operational efficiencies. This is both for security and development teams. Contrast Scan is a pipeline native product that delivers the speed, accuracy and integration required for modern software development.

Seeker® is an advanced interactive application security testing (IAST) tool that offers exceptional insights into the security status of your web applications. It detects trends in vulnerabilities relative to compliance benchmarks such as OWASP Top 10, PCI DSS, GDPR, CAPEC, and CWE/SANS Top 25. Moreover, Seeker allows security teams to monitor sensitive information, ensuring it is adequately protected and not inadvertently recorded in logs or databases without the necessary encryption. Its smooth integration with DevOps CI/CD workflows facilitates ongoing application security assessments and validations. Unlike many other IAST tools, Seeker not only uncovers security weaknesses but also confirms their potential for exploitation, equipping developers with a prioritized list of verified issues that need attention. Utilizing its patented techniques, Seeker efficiently processes a vast number of HTTP(S) requests, nearly eliminating false positives and fostering increased productivity while reducing business risks. In essence, Seeker stands out as a comprehensive solution that not only identifies but also mitigates security threats effectively.

Koi provides enterprises with a first-of-its-kind gateway for managing and securing the software supply chain. It monitors installs across endpoints—covering everything from browser extensions and IDEs to package managers, CI/CD pipelines, and AI models. The platform’s Wings™ engine scans marketplaces hourly, evaluates publisher reputations, and inspects actual code to uncover risks like vulnerabilities, hidden secrets, or embedded malware. Each software asset receives a dynamic risk score that evolves as updates and new versions are released. Security teams gain full visibility into what’s running in their environments, including review statuses and reputation insights for every publisher. Koi also empowers organizations to enforce preventive policies that block up to 70% of marketplace risks in just a few clicks. With automated approvals and customizable guardrails, businesses can adopt new tools faster while staying secure. By unifying discovery, risk reporting, and policy enforcement, Koi delivers enterprise-grade protection without hindering developer productivity.

A novel approach to security tailored to modern software development processes has emerged. By embedding security directly into the development toolchain, issues can be addressed within minutes of installation. Contrast agents actively monitor the code and provide insights from within the application, empowering developers to identify and resolve vulnerabilities without the need for specialized security personnel. This shift allows security teams to concentrate on governance and oversight. Additionally, Contrast Assess features an advanced agent that equips the application with intelligent sensors for real-time code analysis. This internal monitoring significantly reduces false positives, which often hinder both developers and security teams. By integrating seamlessly into existing software life cycles and aligning with the tools that development and operations teams currently utilize, including direct compatibility with ChatOps, ticketing platforms, and CI/CD pipelines, Contrast Assess simplifies the security process and enhances team efficiency. As a result, organizations can maintain a robust security posture while streamlining their development efforts.
