Local License Server for Licensing Your Software in Dark Sites
License your software in offline, internet-restricted environments and secure premises — with the same entitlement models, the same APIs, and the same control plane as your cloud-connected customers.
Sell & Deliver to Dark Sites
Enforce licensing where internet access isn't available
Customers operating dark sites still need modern licensing — locked down for security reasons, not because their requirements are simpler.
Secure Environments
Licensing runs inside the network your customer already controls, with nothing reaching back out by default. Meeting end-customer requirements.
Zero Internet Required
Enforcement happens fully on-premises — built for dark LANs in defense, government, industrial, and other secure environments.
Any Licensing Model
Named users, floating features, element pools, consumption, and more — the full model range, not a stripped-down offline mode.
Live Entitlement Enforcement
Not a static license file. A real entitlement system enforcing policy in real time, even fully offline, with complete auditability.
Why Vendors Adopt This
Sell to the customers your competitors get disqualified from
For end-customers with strict security and restricted-network requirements, dark-site licensing isn't a preference — it's a purchasing condition. A Local License Server lets you meet that condition, compete for these high-value accounts, and grow them with the same modern pricing models you already sell everywhere else.
Win Deals Competitors Get Disqualified From
Enterprise security reviews often rule a vendor out before price or features are ever discussed, the moment licensing requires outbound internet access. A Local License Server removes that blocker before it costs you the deal.
Sell Into Regulated, High-Security Verticals
Defense, government, critical infrastructure, and other regulated industries are some of the largest, stickiest accounts available — and most require dark-site, restricted-network licensing as a condition of purchase, not a nice-to-have.
Grow Revenue Without Compromising on Pricing
Bring the same subscription, usage-based, and consumption models you sell to cloud customers into dark-site accounts — instead of falling back to a stripped-down perpetual license just because the network is restricted.
Non-Internet Connected Environments
A modern solution for hybrid and offline environments
In today's cloud-centric world, finding a reliable, modern licensing solution for hybrid and offline, non-internet-connected environments is hard. Dongles and hardware-based solutions are now specialized and rarely a fit for general-purpose software.
Zentitle's Local License Server is a modern, re-imagined solution for hybrid and fully offline software products.
If you were to tell us that consumption-based licensing is only on the cloud, we could not continue.

A static license file solves the technical problem of granting access. A Local License Server solves the business problem of protecting revenue and scaling modern pricing.
Static License Files
A static license file is a fixed artifact issued once and never checked again — the traditional way of licensing offline software.
- License files are fixed, pre-issued artifacts with no live control
- License files are vulnerable to copying, piracy, and untracked usage
- License files are limited to simple, one-time licensing models
Local License Server
Zentitle's Local License Server is a Docker container running the entitlements inside the customer's network.
- The Local License Server is a live entitlement system enforcing policy in real time — even offline
- The Local License Server provides continuous, local enforcement with full usage auditability
- The Local License Server supports modern models: usage-based, hybrid, and more
Any Licensing Model
Not restricted like competing solutions
Use license models from subscriptions to usage-based, multi-seat to concurrent seats and features — monetize effectively even within technologically challenging environments.
Named Users
Licenses bound to individual users rather than machines.
Floating / Concurrent
Shared seat pools that limit simultaneous use, not total seats.
Element Pools
Shared allowances across features, modules, or entitlement types.
Consumption-Based
Usage-based pricing tracked and enforced entirely on-premises.
High / Low Water Marks
Track peak and minimum usage across a billing period.
Overdraft Monitoring
Allow controlled over-usage while keeping it fully visible and auditable.
Easy to Deploy, Reduced Support Costs
Runs in Docker containers for easy deployment
Your customers get the peace of mind and security they require, and can get on with the software they bought from you. The friction has been taken out of licensing dark sites — simplicity for customers drives down your support overhead.
Easy for Customers
Up and running in minutes — no dongles, no custom install process, nothing to maintain.
Easy for You
Same activation flow and control plane as your cloud customers — nothing bespoke to build.
Activated Like Any Product
Standard Zentitle activation — no bespoke setup process
Docker
Compose for simple setups, Swarm or Kubernetes for production
Health
Built-in health monitoring endpoint
Less Support Required
Simple, self-contained deployment means fewer tickets to get customers live — and keep them running.
