Keep proven business behavior
Start with the live application and let RPG, COBOL, and Db2 continue to own validation and transaction state.
About the product
Preserve the IBM i application. Improve the way people reach it.
PristineScreen400 is an S-Block Technologies LLC product built around a practical premise: a working IBM i application should not require a high-risk rewrite just to gain managed browser access, protected credential handling, or a clearer interface for selected workflows.
Direct answer
Who operates PristineScreen400?
S-Block Technologies LLC develops and operates PristineScreen400 as a managed product for organizations that depend on IBM i applications. Product evaluation begins with a representative workflow, security boundary, and compatibility review.
Operating principles
Modern access should not weaken the host boundary.
Constrain every new surface
Keep targets, credentials, capabilities, and presentation assignments under explicit server policy.
Change at a useful pace
Introduce browser access first, then add branding or exact-screen templates only where they create value.
