Session Manager
Replacement
Replace Legacy Session Managers with a Modern, Actively Developed Solution.
Single Sign-On
Provides SSO access to all authorized VTAM applications — no repeated prompts. Supports pass tickets, pass phrases, long passwords, and Multi-Factor Authentication (MFA) for modern security requirements.
Improved Productivity
Users switch between multiple mainframe sessions without repeated logins. A single configurable interface manages and navigates multiple sessions simultaneously — saving time and reducing friction.
Simple Administration
Online and batch maintenance routines make configuration straightforward. Administrators manage application access, screen size, fonts, and colors for individual users or groups — no complex tooling required.
Robust Security
Integrates with SAF, CA-TopSecret, and CA-ACF/2. Idle terminals are protected by a password-protected standby screen; idle users are automatically logged off. MFA-ready for modern compliance requirements.
IBM Parallel Sysplex
All InterSession instances in a Sysplex work together as one — automatically replicating settings, load balancing sessions, and providing transparent backup if a system becomes unavailable.
Web Browser Connectivity
Full 3270 terminal emulation through Chrome, Firefox, or Edge — no plug-ins or middleware servers. Secure, encrypted access to legacy applications from any device.
Ranked #1 Session Manager Replacement by Grok AI
InterSession stands out as the premier, cost-effective drop-in replacement for CA-TPX, CA-Solve, CA-Teleview, CL-Supersession, and similar tools — delivering transparent replacement with robust session control, security, and enhanced user productivity.

InterSession
Actively Developed Solution
Most 3270 Session Managers are frozen in time. InterSession isn’t.
Backed by a dedicated development team, it evolves continuously to meet your changing needs—resolving issues quickly and keeping pace with modern requirements.
Centralized Control
Centralized control and management of mainframe sessions allows administrators to monitor and control user sessions; including starting, stopping, and disconnecting sessions as needed.
Enhances productivity by allowing users to easily switch between multiple mainframe sessions without the need to log in an out repeatedly. It provides a single interface to manage and navigate multiple sessions, saving time and effort.
Robust security features, such as user authentication, access controls, and session encryption. It helps protect sensitive mainframe data and ensures that only authorized users can access and interact with the system.
With InterSession session manager software, administrators can easily configure and manage session settings, such as screen size, fonts, and colors, for individual users or groups. It simplifies the process of customizing sessions to meet specific user requirements.
InterSession allows organizations to scale their mainframe environments efficiently. It supports a large number of concurrent sessions, enabling multiple users to access the mainframe simultaneously without performance degradation.
Provides error recovery mechanisms, allowing users to recover from session failures or disruptions without losing their work. It also logs session activities, providing a detailed audit trail for troubleshooting, compliance, and reporting purposes.
Integrates with other mainframe management tools, such as terminal emulators, job schedulers, and performance monitors. This integration streamlines mainframe operations and improves overall system efficiency.
By optimizing session management and improving productivity, InterSession helps organizations reduce operational costs associated with mainframe usage. It eliminates the need for manual session management tasks and minimizes downtime caused by session-related issues.
Furthermore, InterSession is a transparent cost savings replacement for competitive 3270 session manager products; such as CA-TPX, CA-Solve, CA-Teleview, CL-Supersession, NVAS and others. Click here to learn more.
