Unizo - Unified API and Data Fabric for Security

Unizo is a unified API and data fabric that helps security platforms simplify how they build, scale, and operate integrations across the enterprise stack. Modern security products depend on data, signals, and state from dozens or even hundreds of external systems spanning identity, endpoint, cloud, developer tools, ITSM, messaging, and GRC platforms. Building and maintaining these integrations individually is expensive, fragile, and slows down product velocity. Unizo solves this problem by providing a single, normalized integration layer that replaces fragmented, one-off integrations with unified APIs and real-time event streams. With Unizo, teams integrate once and gain consistent access to enterprise data across categories. The platform abstracts away the operational complexity of third-party integrations, including authentication, pagination, rate limits, schema differences, and ongoing vendor API changes. This significantly reduces engineering effort and lowers the risk of broken workflows as vendors evolve. In addition to unified APIs, Unizo supports real-time events and webhooks to capture state changes such as user updates, asset changes, findings, incidents, or control status updates. On top of raw and normalized data, Unizo also provides Decision-Ready Signals (DRS) - high-level, question-oriented APIs that return actionable answers (for example, whether MFA is enforced org-wide or whether a control is compliant) without requiring downstream systems to stitch data across multiple tools. Unizo is designed to be agent-ready. It includes native support for Model Context Protocol (MCP), enabling AI agents and automation systems to securely access structured, permission-scoped enterprise context. This allows security platforms to power agentic workflows while maintaining auditability, control, and deterministic behavior. To support enterprise and regulated environments, Unizo offers white-label connection UI and SDKs for faster onboarding, built-in observability and auditing, scoped access controls, and flexible deployment options including SaaS, embedded, and hybrid models. Organizations use Unizo to accelerate integration rollout, reduce long-term maintenance burden, improve reliability, and confidently scale their integration ecosystem while preparing their platform for AI- and agent-driven security workflows.

World Data API

World Data API consolidates the reference data that developers typically pull from multiple separate APIs. Instead of integrating REST Countries for geography, TimezoneDB for timezones, Calendarific for holidays, and separate sources for airports and astronomy - you get one API with one authentication scheme, one response format, and interconnected data. Query an airport and get its timezone. Query a country and get its neighbors, currencies, and upcoming holidays. The relationships are built in and structured. Coverage includes 250+ countries with 5000+ regions, 316 IANA timezones, holidays for 230+ countries with regional breakdowns, 10,000+ airports, currencies, languages, and astronomy calculations (sunrise/sunset, golden hour, moon phases). Free tier available with 60 requests/day, and paid plans include more usage at a lower cost than competitors.
