Prelude Verification APIs

Prelude

Prelude Verification APIs (also known as Prelude Verify) provide a developer-friendly, robust, and secure platform for implementing One-Time Password (OTP) and SMS-based user verification. Designed to ensure high deliverability and conversion rates globally, the API manages the entire verification lifecycle, from initiating requests to validating codes. A core strength lies in its advanced, AI-powered anti-fraud system, which actively detects and prevents various forms of fraud, such as SMS pumping and International Revenue Share Fraud (IRSF), by analyzing digital signals and historical data. This helps businesses reduce costs associated with fraudulent activities and improve user onboarding KPIs. The service offers smart routing across numerous carriers and channels to optimize delivery and cost-efficiency. It is delivered as a SaaS solution with comprehensive SDKs for seamless integration into web, mobile, and backend applications, catering to developers, product managers, and growth teams focused on secure and efficient user authentication.

Prelude Detect

Prelude

Prelude Detect is a continuous security testing and validation platform designed to automate the assessment of an organization's security posture against the latest cyber threats. It operationalizes threat intelligence by transforming it into actionable security tests, detections, and hunting queries, enabling enterprises to continuously validate and enhance their security defenses at scale. The platform utilizes lightweight, ephemeral or persistent "probes" that are safely deployed on endpoints and cloud workloads to simulate real-world attack techniques. This process identifies vulnerabilities and measures the effectiveness of existing security controls, such as Endpoint Detection and Response (EDR) systems and Security Information and Event Management (SIEM) solutions. Prelude Detect integrates seamlessly with a wide array of security tools, including CrowdStrike, Microsoft Defender, SentinelOne, and Splunk, to provide continuous, agentless visibility into control coverage, configuration, and performance. By distinguishing between theoretical and real vulnerabilities, it empowers security teams to prioritize remediation efforts effectively, thereby improving overall security resilience and ensuring compliance with minimal manual intervention. The platform also leverages advanced AI capabilities to rapidly translate complex threat intelligence documents into validated protections and detections, allowing organizations to adapt to evolving threats at machine speed.

Prelude Session

Prelude

Prelude Session is a secure and scalable session management system offered by Prelude.so as part of its suite of APIs designed to enhance onboarding and trust processes. It provides developers and businesses with the tools to manage the entire lifecycle of user sessions, from creation and validation to termination and renewal. The platform emphasizes strong security boundaries through application-level isolation, ensuring that data and operations for one application remain separate from others. This multi-tenancy capability allows organizations to manage different environments (development, staging, production) or distinct products with complete data separation. By offering a robust and API-driven approach to session management, Prelude Session helps businesses maintain secure user access, prevent unauthorized session hijacking, and ensure compliance with security best practices, ultimately contributing to a more secure and reliable user experience.
