Security

Asterisk (asterisk.so) is an AI Hacker for Codebases - it automatically finds, verifies, and patches security vulnerabilities in codebases, just like a human security engineer would. Asterisk can find business logic errors with context-aware scanning and automate the full auditing cycle to generate reports with near-zero false positives. Asterisk has autonomously discovered vulnerabilities in Google, Hoppscotch, and others.

General Analysis

Security

General Analysis provides a comprehensive suite of AI safety tools, including red-teaming frameworks, interpretability techniques, and more. As AI systems become increasingly capable, their deployment in high-stakes environments poses significant risks, financial, ethical, and otherwise, where errors can lead to substantial consequences. To address these challenges, we offer access to novel tools and methodologies designed to systematically find model failure-modes and enhance model robustness.

Tesseral is the open source platform for managing identity and access in business software. It provides enterprise-grade capabilities, including SAML single sign-on, SCIM provisioning, role-based access control, managed API keys, and audit logs, implemented in just a few lines of code. Tesseral unifies access management for employees, customers, services, and AI agents, giving organizations the flexibility to adapt to any deployment model and the authority to enforce security policies with precision. You can learn more by reading our docs at https://tesseral.com/docs or by checking out our GitHub at https://github.com/tesseral-labs/tesseral.

Superagent

Security

Superagent provides guardrails that make AI products secure and compliant. It's a suite of purpose-trained small language models that run at runtime to protect, verify, and redact data flowing through AI systems. - GUARD detects and blocks unsafe inputs, prompt injections, and malicious tool calls before they reach your models - VERIFY grounds and validates outputs against enterprise sources to ensure every generation is factual and policy-aligned - REDACT removes sensitive data (PII, PHI, secrets) to maintain privacy and compliance Superagent integrates via API, SDKs, CLI, MCP, and web Playground, with a unified dashboard for policies, logs, and compliance visibility.

Gecko Security

Security

We built Gecko for teams that want to build secure code quickly without wasting time on security tools that don’t deliver results, or relying on one-time human pentests that quickly become outdated. Gecko uses AI to understand how your application should work, simulates relevant attacks to find critical vulnerabilities, and then verifies these vulnerabilities by exploiting them. It also helps you understand the risk of these vulnerabilities and applies a working fix to keep your code secure.
