LDK integrates with Envelope protection to protect software IP, proprietary algorithms, AI models, and from AI-assisted reverse engineering and vulnerability detection.
One licensing foundation supports desktop, SaaS, embedded, IoT, hybrid, and air-gapped environments with hardware-based, software-based, and cloud-based enforcement technologies.
Sentinel LDK enables deployed licenses to be renewed, extended, revised, or revoked remotely whether products are deployed online or offline. Vendors can adapt customer entitlements without replacing keys or disrupting deployments.
Capabilities
Sentinel LDK toolkit works in parallel with Sentinel EMS to connect enforcement with entitlement management. This creates a unified foundation for translating commercial models into operational reality.
Sentinel LDK captures software usage data, allowing customers to route, analyze, and use usage data for critical business needs.
AI expands what software can do and raises the value of the IP behind it. It also gives attackers faster, AI-assisted ways to reverse engineer products and circumvent licensing controls.
Sentinel LDK gives vendors a proven way to respond, with the ability to monetize any software product, including AI-powered applications, while keeping control of how it is used. As products and threats evolve, LDK gives you the confidence to bring new technology to market and protect its value.
