Aladdin HASP License Manager
Port 1947 is primarily used by the Aladdin HASP License Manager, a system responsible for managing software licensing through hardware or software-based security keys. This service enables developers and organizations to enforce copy protection, ensure software compliance, and administrate license allocation via network communication..
Port 1947 is designated for the Aladdin HASP License Manager (later SafeNet Sentinel), a network service that facilitates communication between protected software applications and local or remote licensing servers equipped with a HASP Hardware Security Module (dongle) or a software-based license. The license manager serves requests from client machines to authenticate licenses, enforce usage limits, or update licensing information dynamically.
Licensing servers listen on TCP port 1947, enabling centralized management and monitoring across distributed environments. The service supports various protocols and functions, including license borrowing, concurrency management, and feature entitlement verification. It integrates with developer SDKs to embed protection controls within software products.
The HASP framework is widely integrated into commercial software across verticals — CAD, engineering, scientific, media production — to combat piracy. The license manager communicates licensing status updates and responds to API calls from client software to permit or deny access based on valid entitlements stored on the licensing server or dongle.
