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.

SonarQube Server serves as a self-hosted solution for ongoing code quality assessment, enabling development teams to detect and address bugs, vulnerabilities, and code issues in real time. It delivers automated static analysis across multiple programming languages, ensuring that the highest standards of quality and security are upheld throughout the software development process. Additionally, SonarQube Server integrates effortlessly with current CI/CD workflows, providing options for both on-premise and cloud deployments. Equipped with sophisticated reporting capabilities, it assists teams in managing technical debt, monitoring progress, and maintaining coding standards. This platform is particularly well-suited for organizations desiring comprehensive oversight of their code quality and security while maintaining high performance levels. Furthermore, SonarQube fosters a culture of continuous improvement within development teams, encouraging proactive measures to enhance code integrity over time.

Backslash Security is the governance and visibility platform built for organizations where AI coding tools are already part of how software gets built. GitHub Copilot, Cursor, Windsurf, Claude Code, and Gemini CLI have fundamentally changed the development lifecycle — and the security controls most organizations rely on were not designed for this environment. Backslash provides a comprehensive AI coding tool inventory and policy enforcement across the full AI coding spectrum, giving security teams visibility into every active tool and the risk introduced before it reaches production. This includes vibe coding security — risk detection purpose-built for vulnerability patterns in AI-generated code that traditional scanners are not equipped to catch. As AI coding agents grow more capable, they increasingly operate with access to external services, internal data, and organizational infrastructure through MCP servers. Over-permissioned agents and misconfigured MCP connections create data leakage pathways — exposing sensitive organizational data to AI models without security team awareness or enforcement controls. These are active exposure points, not theoretical risks. Backslash addresses this directly. The platform maps every MCP server connection, identifies over-permissioned AI agent configurations, and enforces least-privilege access before data leakage occurs. Security teams gain full visibility into what AI agents can access and where permissions exceed what the task requires. For security leaders governing an environment that moved faster than their controls, Backslash is the missing layer — built from the ground up for AI-native development, not retrofitted from a previous generation of tooling.

Reduce Mean Time to Detection (MTTD) and Mean Time to Recovery (MTTR) with comprehensive coverage achievable within minutes of deployment. Employ a complete DevSecOps toolchain that spans all your environments, ensuring the implementation and gathering of evidence as part of an ongoing security strategy. This solution is unified and de-duplicated across all orchestrated layers, allowing you to add thousands of checks through a single line of code, enhanced by AI capabilities. Designed with a strong focus on security, it effectively sidesteps prevalent security errors and vulnerabilities, while being adept at understanding contemporary technologies. Every feature is accessible through a REST API, making it easily integrable with CI/CD systems, and it operates in a lightweight and rapid manner. You have the option to self-host for total code governance and transparency, or to utilize a source-available binary exclusively within your own CI/CD pipeline. Opting for a source-available solution grants you complete control and transparency over your security measures. The initial setup is straightforward, necessitating no software installation, and it supports a wide variety of programming languages. This tool is capable of detecting thousands of code and infrastructure-related issues, with the count continually rising. Users can review detected issues, categorize them as false positives, and collaborate effectively on resolutions, fostering a more secure development environment. Continuous updates ensure that the tool remains aligned with emerging security threats and technology advancements.

GitHub Advanced Security empowers developers and security professionals to collaborate effectively in addressing security debt while preventing new vulnerabilities from entering code through features such as AI-driven remediation, static analysis, secret scanning, and software composition analysis. With Copilot Autofix, code scanning identifies vulnerabilities, offers contextual insights, and proposes solutions within pull requests as well as for past alerts, allowing teams to manage their application security debt more efficiently. Additionally, targeted security campaigns can produce autofixes for up to 1,000 alerts simultaneously, significantly lowering the susceptibility to application vulnerabilities and zero-day exploits. The secret scanning feature, equipped with push protection, safeguards over 200 types of tokens and patterns from a diverse array of more than 150 service providers, including hard-to-detect secrets like passwords and personally identifiable information. Backed by a community of over 100 million developers and security experts, GitHub Advanced Security delivers the necessary automation and insights to help teams release more secure software on time, ultimately fostering greater trust in the applications they build. This comprehensive approach not only enhances security but also streamlines workflows, making it easier for teams to prioritize and address potential threats.
