Pricing
Your data stays on the mainframe — accessed live, anywhere. No-code, zIIP-eligible, and installed out of the box.
Licensed by the data volume you actually move, with transparent pricing and no hidden true-ups
$250,000 / year
First terabyte included.
Additional terabytes priced per customer.
What’s Included in Each Lozen™ License
Lozen is licensed by the volume of data you move. The mainframe stays the system of record — accessed live by your cloud and distributed apps, exactly where it already lives.
Access & Architecture
Single source of truth
The data stays on the mainframe — every app works from the same live copy.
Standard NFS, zero client-side code
Cloud and distributed apps connect over standard NFS — no VirtualZ code installed on the client.
Full VSAM semantics preserved
Keyed reads, updates, and deletes all behave exactly as they do on z/OS.
Move only the records you need
Transfer the set of records an app requests — not entire files.
Operations & Security
zIIP-eligible workload
Typically 85–95% of MIPS land on zIIP, minimizing general-purpose impact.
Mainframe security stays intact
Data stays controlled by your existing mainframe security product — no egress.
In-flight transformation
Read VSAM records as JSON, CSV, and more — EBCDIC and packed decimal handled for you.
SMF recording for usage tracking
Track reads and writes through SMF records ahead of renewal.
Volume-Based License
Base License & Volume
Lozen is licensed by data volume — not by MIPS, seats, or LPARs. Start with your first terabyte and add volume as your usage grows.
App Store Model
Pay Only for the Connectors You Need
A base license plus an App Store of connectors. Start with what you need today and expand as you grow — every connector originated from a real customer request.
App Store add-ons below are licensed individually at a flat annual fee — pick and choose, and never pay for connectors you don’t use.
Included in the base license:
VSAM file input and output; sequential, tape, and GDG file handling; a built-in transformation engine; and standard NFS access. Specialized data-lake and monitoring connectors are also available, and partners can build their own via documented APIs.
Why Lozen
When the Data Needs to Stay Put
Some data has to stay on the mainframe — for integrity, security, or compliance. Lozen makes it accessible live, anywhere, without the workarounds teams have traditionally relied on.
The Workarounds
Hand-built data pipelines
Custom unload jobs and file transfers are expensive to build and maintain.
Journaling-based CDC
Forces you to turn on journaling and logging and rethink operational procedures.
Monolithic licensing
Pay for everything whether you use it or not.
Data leaves your control
Moving sensitive data off-platform adds egress and governance burden.
The Lozen Model
No journaling, no CDC
Access data live where it lives — no new operational procedures to adopt.
Modular, pay-as-you-grow
License only the connectors you need; expand over time.
Single source of truth
The data stays on the mainframe — every app reads the same live truth, every time.
Your existing security still protects it
Your RACF, ACF2, or Top Secret policies keep guarding it — and Lozen authenticates remote access with Kerberos, digital certificates, or pass-tickets.
Pricing That Works the Way You Do
Lozen starts with volume-based live data access, then lets you add only the integrations your teams actually need.
Volume-based licensing
Lozen is licensed by the data volume you move — not by MIPS, seats, or LPARs. The first terabyte starts at $250,000; additional terabytes are priced per customer.
An App Store, not a suite
Core connectivity ships in the base license — then start small and add only the apps you need, from Rocket Enterprise Server to data-lake and monitoring connectors. No bloated bundles, no paying for features you’ll never touch. Mix, match, and expand as your needs grow.
Easy to monitor
Built-in SMF recording lets you track reads and writes, so you always understand your usage ahead of renewal. Installs in hours and moves data the same day.
