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.

Matters.AI emerges as the trailblazing AI Security Engineer for Data, crafted to autonomously identify, understand, and resolve cases of data misuse prior to any notifications reaching the Security Operations Center (SOC). This groundbreaking solution offers robust protection for essential data, supervising sensitive information as it exists or transitions across different platforms, working much like a human security engineer that grasps context, observes activities, and independently safeguards confidential data in diverse environments such as cloud services, SaaS, endpoints, microservices, and AI pipelines. Leveraging cutting-edge technologies like semantic intelligence, nearest neighbor search, data lineage modeling, and predictive behavior analysis, Matters transcends traditional threat detection by interpreting context, anticipating possible dangers, and taking preemptive actions. Unlike conventional methods reliant on static rules, regex patterns, cumbersome dashboards, and incessant alerts, Matters skillfully interprets subtle data signals, monitors risks in real-time, and functions continuously. By recognizing sensitive information not just by its format but by its importance, Matters utilizes approaches such as fingerprinting and eBPF to oversee data across cloud environments, SaaS applications, endpoints, and beyond, guaranteeing thorough protection and heightened awareness. Ultimately, Matters.AI not only bolsters data security but also revolutionizes the risk management landscape in our increasingly digital world, reshaping how organizations approach data integrity and safety. Furthermore, this innovative solution empowers businesses to maintain compliance and fosters a culture of security awareness among employees.

GuardionAI functions as both an Agent and a MCP Security Gateway, providing all-encompassing security for AI agents and Model Context Protocol tools that engage with enterprise data. Strategically integrated within the execution path, it proficiently detects and redacts sensitive information, enforces protective measures, and grants improved visibility into activities often overlooked by traditional SIEM, DLP, and identity frameworks. Every action taken by agents is thoroughly monitored, enforced, and recorded at the protocol level, covering a wide array of components including AI agents, LLM applications, RAG systems, chatbots, coding assistants, MCP servers, internal applications, databases, operating systems, and cloud infrastructures. GuardionAI is specifically engineered to mitigate critical vulnerabilities in AI, such as prompt injection, system overrides, web-based attacks, MCP tool tampering, harmful code execution, inappropriate content exposure, leakage of personally identifiable information and credentials, unauthorized access to sensitive data, off-topic drift, and violations of access control, all in accordance with the OWASP LLM Top 10 and agentic AI threat frameworks. Furthermore, the gateway features a formidable four-layer protection system, ensuring that organizations can effectively secure their AI assets like never before. This comprehensive strategy not only bolsters security but also equips teams with the necessary insights to adeptly navigate the intricacies of modern AI landscapes, ultimately fostering a more robust defense against emerging threats. In an age where data integrity is paramount, GuardionAI stands as a critical partner in safeguarding enterprise resources.

Constellation Gate AI acts as a supplementary defense layer for AI agents, strategically placed between the agent and the model to scrutinize all requests for possible risks and data breaches. This innovative solution operates as an inline gateway for coding agents and model APIs, safeguarding workflows without requiring extensive code alterations. Users can seamlessly direct their existing tools such as Claude Code, Cursor, OpenClaw, Codex, or OpenCode to engage with Gate, thereby securing defenses against prompt injection, secret exposure, PII redaction, token optimization, and maintaining a trustworthy audit trail. The platform effectively tackles three significant vulnerabilities: prompt injection attacks, unauthorized access to credentials and PII, and illicit tool activations. Instead of relying solely on the model's built-in defenses, Gate proactively intercepts potential attacks before they reach the model, eliminates sensitive data from responses before they are returned, and blocks outputs from compromised tools before agents can utilize them. Gate remains compatible with the standard calls made by agents, forwarding them to the model while thoroughly analyzing each request and response in both directions, thereby providing robust protection against evolving threats. This forward-thinking strategy not only bolsters security but also cultivates user confidence in the reliability and safety of their AI operations, ultimately fostering a more secure environment for innovation.
