Scalekit is an authentication and integration platform designed specifically for AI agents that need to securely connect with SaaS applications, APIs, MCP servers, databases, and internal systems. The platform enables agents to act on behalf of individual users instead of using shared service accounts, ensuring every action follows the user's identity, permissions, and approved access scopes. Scalekit manages delegated OAuth authentication, secure credential vaulting, token lifecycle management, authorization checks, and API communication without requiring developers to build that infrastructure themselves. Developers can connect to more than 100 prebuilt integrations or create custom connectors for proprietary services and internal APIs. Built-in handling for pagination, retries, rate limiting, and error management simplifies tool execution while improving application reliability. Every request is logged with a complete delegation chain that records the user, agent, connector, permissions, and resulting actions for auditing and compliance. The platform supports encrypted credential storage, regional deployments, private cloud options, SIEM integrations, and enterprise-grade security controls. Scalekit also extends beyond AI agents by providing SaaS authentication capabilities such as SSO, SCIM provisioning, RBAC, passwordless authentication, and user management. By combining delegated identity, secure authentication, and production-ready connector infrastructure, Scalekit enables organizations to build trustworthy AI agents without the complexity of managing authentication themselves.

Engineered entirely in Go, HoneyWire delivers a self-hosted, open-source deception engine that identifies post-exploitation and lateral movement without the heavy footprint of commercial enterprise software. Using an intuitive Terminal UI (TUI) wizard, security teams and sysadmins can rapidly distribute distroless, lightweight canary tripwires across any Linux environment in a matter of seconds. Our detection model guarantees an absolute zero false-positive rate. Because every HoneyWire sensor operates as a strictly synthetic decoy, they possess no actual business utility. Consequently, any network interaction with these endpoints is a guaranteed indicator of compromise whether from a rogue internal script, a breached CI/CD pipeline, or a live adversary. The platform ships with a growing arsenal of ready-to-deploy traps: - TCP Canary Tarpits: Occupy attractive network ports to capture malicious payloads and bog down automated enumeration tools. - Fake Web Routers: Mimic administrative dashboards to snare HTTP-focused reconnaissance. - Honeytoken File Canaries: Covert file integrity monitors that trigger the instant an attacker reads or scrapes sensitive decoy directories. - Network & ICMP Sensors: Unmask stealthy subnet discovery and ping sweeps before hostile actors can map your production assets. (Expect new trap types in upcoming releases!) Fleet configuration and node telemetry are centrally orchestrated by the HoneyWire Hub a secure, fully private control server. To seamlessly integrate with your existing EDR or SIEM infrastructure, the Hub dispatches dynamic alerts through standard Syslog, alongside native push notification support for Slack, Discord, Gotify, and Ntfy.
