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.

Modern security teams are focused on fostering a collaborative atmosphere for developers by integrating code guardrails with every commit they make. Utilizing r2c’s Semgrep allows organizations to eliminate various types of vulnerabilities effectively and seamlessly. By adopting lightweight static analysis tools, the productivity of your security team can be significantly improved. Semgrep is recognized as a fast and open-source static analysis tool that makes it easy to express coding standards without complicated queries, facilitating early bug detection during the development cycle. The rules are intentionally crafted to reflect the code being examined, which removes the hurdles of navigating abstract syntax trees or wrestling with regex intricacies. You can effortlessly begin using over 900 available rules and leverage SaaS infrastructure for immediate feedback right in your editor, at the point of commit, or within continuous integration setups. Should the default rules fail to address your particular requirements, crafting custom rules that align with your organization’s coding standards is a quick and straightforward process, with syntax that mirrors the target code. For example, rules designed for Go are structured to align closely with the Go language, enabling the identification of function calls, class and method definitions, and more, all without the complications associated with abstract syntax trees or regex issues. This method not only simplifies the security workflow but also equips developers to produce high-quality code more efficiently and confidently, ultimately benefiting the overall development process. By embracing such tools, organizations can create a culture of security that becomes an integral part of the development lifecycle.

StackHawk inspects your ongoing applications, services, and APIs for potential security issues that may arise from your development team, along with vulnerabilities in open-source components that could be at risk of exploitation. In the current engineering environment, it has become commonplace to integrate automated testing suites within CI/CD frameworks. Therefore, it begs the question: why shouldn't application security adapt in a similar manner? StackHawk is tailored to uncover vulnerabilities directly within your development workflow. The motto "built for developers" captures the essence of StackHawk, highlighting the need to weave security seamlessly into the development lifecycle. As the landscape of application security progresses to match the fast pace of contemporary engineering teams, it is crucial for developers to have access to tools that facilitate the assessment and resolution of security vulnerabilities. With StackHawk, security measures can evolve alongside development efforts, enabling teams to identify vulnerabilities during pull requests and address them promptly, in contrast to traditional security solutions that often delay action until after manual scans are performed. This tool not only fulfills the requirements of developers but is also supported by the most widely utilized open-source security scanner, making it a preferred choice among users. Ultimately, StackHawk empowers developers to fully integrate security into their routine tasks, fostering a culture of proactive risk management within their projects. Additionally, this allows organizations to enhance their overall security posture while maintaining efficiency in their development processes.

GitHub Advanced Security enables developers and security experts to work together efficiently in tackling existing security issues and preventing new vulnerabilities from infiltrating code through a suite of features like AI-driven remediation, static analysis, secret scanning, and software composition analysis. By utilizing Copilot Autofix, vulnerabilities are detected through code scanning, which provides contextual insights and suggests fixes within pull requests as well as for previously flagged alerts, enhancing the team's capacity to manage their security liabilities. Furthermore, targeted security initiatives can implement autofixes for as many as 1,000 alerts at once, significantly reducing the risk of application vulnerabilities and zero-day exploits. The secret scanning capability, which includes push protection, secures over 200 different token types and patterns from a wide range of more than 150 service providers, effectively identifying elusive secrets such as passwords and personally identifiable information. Supported by a vast community of over 100 million developers and security professionals, GitHub Advanced Security equips teams with the automation and insights needed to deliver more secure software promptly, thereby promoting increased confidence in the applications they develop. This holistic strategy not only bolsters security but also enhances workflow efficiency, making it simpler for teams to identify and tackle potential threats, ultimately leading to a more robust security posture within their software development lifecycle.
