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.

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.

Contemporary security teams are essentially creating a supportive environment for developers by implementing code guardrails with each commit. With the capabilities of r2c’s Semgrep, organizations can effectively eradicate classes of vulnerabilities across the board. Enhance the efficiency of your security team through the use of lightweight static analysis tools. Semgrep stands out as a rapid, open-source static analysis solution that simplifies the expression of coding standards without the need for complex queries, allowing for early detection of bugs in the development process. The rules are designed to mirror the code being analyzed, eliminating the challenges associated with navigating abstract syntax trees or dealing with regex complexities. You can easily get started with over 900 pre-existing rules and utilize SaaS infrastructure to receive quick feedback directly in your editor, at the time of commit, or within continuous integration environments. If the standard rules do not meet your specific needs, you can swiftly and easily craft custom rules that reflect your organization’s unique coding standards, with the syntax resembling the target code. For instance, rules tailored for Go are presented in a way that aligns closely with the Go language itself, enabling you to identify function calls, class and method definitions, and much more without the burden of abstract syntax trees or regex challenges. This approach not only streamlines the security process but also empowers developers to maintain high-quality code more efficiently.

StackHawk evaluates your active applications, services, and APIs for potential security flaws introduced by your team, as well as for vulnerabilities in open-source components that could be exploited.

For those utilizing GitHub Actions in their CI/CD processes and concerned about the security of their pipelines, the StepSecurity platform offers a robust solution. It allows for the implementation of network egress controls and enhances the security of CI/CD infrastructures specifically for GitHub Actions runners. By identifying potential CI/CD risks and detecting misconfigurations in GitHub Actions, users can safeguard their workflows. Additionally, the platform enables the standardization of CI/CD pipeline as code files through automated pull requests, streamlining the process. StepSecurity also provides runtime security measures to mitigate threats such as the SolarWinds and Codecov attacks by effectively blocking egress traffic using an allowlist approach. Users receive immediate, contextual insights into network and file events for all workflow executions, enabling better monitoring and response. The capability to control network egress traffic is refined through granular job-level and default cluster-wide policies, enhancing overall security. It is important to note that many GitHub Actions may lack proper maintenance, posing significant risks. While enterprises often opt to fork these Actions, the ongoing upkeep can be costly. By delegating the responsibilities of reviewing, forking, and maintaining these Actions to StepSecurity, businesses can achieve considerable reductions in risk while also saving valuable time and resources. This partnership not only enhances security but also allows teams to focus on innovation rather than on managing outdated tools.
