The software development lifecycle has undergone a fundamental shift. Across engineering organizations of every size, developers are using AI coding tools — GitHub Copilot, Cursor, Windsurf, Claude Code, Gemini CLI — as a core part of how software gets built. These tools accelerate delivery, but they also introduce a new and largely ungoverned attack surface that traditional security products were never designed to address. Backslash Security was built specifically for this environment. The platform gives security teams comprehensive visibility into the AI coding tools active across their organization, the code being generated, and the risk being introduced before it ever reaches production. This is not a legacy scanner retrofitted for a new market. Every capability in Backslash was designed from the ground up with AI-native development in mind. A critical risk vector is MCP servers — the infrastructure AI coding agents use to connect to external services and data sources. Misconfigured or over-permissioned MCP servers can expose sensitive organizational data to AI models, creating data leakage pathways that are invisible to conventional security tooling. Backslash provides full visibility into MCP server connections, flags over-permissioned configurations, and enforces access controls before exposure occurs. Core capabilities include AI coding tool inventory and policy enforcement, MCP server visibility and over-permission detection, data leakage prevention across AI agent connections, vibe coding security for risk detection in AI-generated code, and continuous monitoring across the full AI coding spectrum. The organizations that need Backslash have already crossed the AI coding adoption threshold. Their developers are moving fast, AI tools are embedded in daily workflows, and security visibility has not kept pace. Backslash closes that gap — giving security teams the control and confidence to let development move at the speed the business demands.

Boost your efficiency by ensuring that only top-notch code is deployed, as SonarQube Cloud (formerly known as SonarCloud) effortlessly assesses branches and enhances pull requests with valuable insights. Detecting subtle bugs is crucial to preventing erratic behavior that could negatively impact users, while also addressing security vulnerabilities that pose a risk to your application, all while deepening your understanding of application security through the Security Hotspots feature. You can quickly start utilizing the platform directly from your coding environment, allowing you to take advantage of immediate access to the latest features and enhancements. Project dashboards deliver essential insights into code quality and release readiness, ensuring that both teams and stakeholders are well-informed. Displaying project badges highlights your dedication to excellence within your communities and serves as a testament to your commitment to quality. Recognizing that code quality and security are vital throughout your entire technology stack—covering both front-end and back-end development—we support an extensive selection of 24 programming languages, including Python, Java, C++, and more. As the call for transparency in coding practices increases, we encourage you to join this movement; it's entirely free for open-source projects, presenting a valuable opportunity for all developers! Additionally, by engaging with this initiative, you play a role in a broader community focused on elevating software quality and fostering collaboration among developers. Embrace this chance to enhance your skills while contributing to a collective mission of excellence.

DryRun Security helps AppSec and Product Security leaders keep up with modern code change volume using AI Native SAST and Agentic Code Security. It is built for application security and developer teams that need higher-signal findings, consistent guardrails, and faster evidence for audits, without slowing development. DryRun Security is powered by its Contextual Security Analysis engine, which understands code and intent to reduce false positives and surface risks that pattern-based scanning often misses. How teams use DryRun Security: Code Review Agent: PR-native security feedback within moments of a push, delivered as comments and checks. Custom Policy Agent: enforce Natural Language Code Policies, written in plain English, on every pull request. DeepScan Agent: on-demand full-repository security assessments in about an hour, with a prioritized report engineers can fix fast. Code Insights Agent: visibility into trends, posture, and reporting across repos. DryRun Security works with GitHub and GitLab permission models. It protects security with private LLM capabilities, avoids sending code to public AI systems, and processes data with ephemeral services, while retaining only findings and minimal metadata for reporting.

Codex Security is an AI-powered security agent developed by OpenAI to assist teams in identifying and resolving vulnerabilities within their software systems. The tool analyzes entire code repositories to understand how applications function and where potential risks may exist. By building a system-specific threat model, Codex Security gains deeper context about trusted components, external dependencies, and possible attack surfaces. This contextual understanding allows the system to detect complex vulnerabilities that traditional static analysis tools might miss. The platform prioritizes security findings based on their real-world impact rather than simply reporting large numbers of potential issues. Codex Security also validates vulnerabilities using sandbox environments to confirm whether the issues are exploitable. This validation process significantly reduces false positives and helps security teams focus on genuine threats. When vulnerabilities are discovered, the system recommends code patches that align with the architecture and intended behavior of the application. These suggested fixes help developers implement secure solutions without disrupting existing functionality. Codex Security can continuously learn from user feedback to refine its threat model and improve detection accuracy. The system is designed to operate across large codebases and analyze thousands of commits efficiently. Overall, Codex Security enables organizations to strengthen software security workflows while accelerating development and deployment processes.
