Modern engineering teams have a math problem: AI coding assistants now produce the majority of new code, but the security stack underneath was built for an era when humans typed every line. Plexicus rewires that equation. We're an AI-native ASPM platform with Vibe Coding Security at its core — the first end-to-end solution that meets developers where they actually work, whether they're writing code by hand or pair-programming with Cursor, Claude Code, Copilot, Windsurf, Devin, Replit, Zed, or VS Code (JetBrains coming). What sets Plexicus apart isn't another dashboard of findings. It's the autonomous remediation loop: every detected risk arrives with a GenAI-generated pull request that fixes the root cause, lands in the developer's normal Git workflow, and clears triage queues before they form.

Additionally, Dash0 empowers teams to respond proactively to system issues, ensuring optimal performance and reliability across their applications.

VibeSecurity is an advanced platform that employs artificial intelligence to conduct vulnerability scans, aimed at safeguarding code generated by AI by persistently evaluating, identifying, and addressing security weaknesses throughout the entire development process. This solution specifically targets contemporary “vibe coding” practices, where developers utilize AI tools to swiftly create code, often inadvertently incorporating concealed vulnerabilities such as insecure authentication methods, exposed tokens, or risks of injection attacks. It leverages intelligent agents to execute real-time analyses of the code, pinpointing security concerns prior to their deployment and offering automated recommendations for fixes along with guidance for implementation. By seamlessly integrating with developer environments via IDE plugins, GitHub applications, and CI/CD pipelines, it facilitates ongoing surveillance of repositories, pull requests, and deployments while ensuring that workflows remain uninterrupted. Additionally, VibeSecurity empowers developers by providing them with the tools they need to enhance the security of their code as they work, ensuring a proactive approach to vulnerability management.

Knostic functions as a comprehensive platform for enterprise AI security and governance, aiming to safeguard against data leaks and regulate the manner in which large language models utilize and disseminate information within businesses. It implements access controls based on a “need-to-know” principle, which adaptively decides what data an AI can disclose according to the user's role, the context, and their intent, instead of depending solely on conventional file permissions. By concentrating on the knowledge layer that exists between unprocessed data and AI-generated outputs, it scrutinizes how information is inferred, merged, and presented to guarantee that sensitive material is not inadvertently shared. Knostic also ensures ongoing monitoring of AI operations across various applications, including Copilot and other assistants powered by large language models, while pinpointing potential threats like semantic oversharing, exposure through inference, and unauthorized access to knowledge. Furthermore, it conducts simulations of practical prompts to reveal unnoticed vulnerabilities prior to their implementation, assigns numerical risk evaluations, and empowers organizations to apply detailed policies effectively. This dual focus on proactive risk assessment and ongoing governance positions Knostic as an essential tool for safeguarding organizational integrity in the evolving landscape of AI technology.
