It supports both Layer 3 (Network Connect) and Layer 7 (Application Level) access, ensuring that sensitive data remains protected during transmission over public networks.

While Ivanti (the current owner of the Pulse Secure portfolio) has transitioned many organizations to the newer "Ivanti Secure Access" client, version 9.1.15 remains a critical download for organizations maintaining specific legacy infrastructure or those utilizing on-premise PCS appliances that have not yet migrated to the latest iteration.
Important Note on Security: The Pulse Secure product line has been the target of intense scrutiny regarding cybersecurity vulnerabilities. Organizations downloading version 9.1.15 should ensure they are downloading it from a verified source (such as the official Ivanti download portal) and that the file integrity matches the published checksums.
Furthermore, this specific version addresses several vulnerabilities present in older iterations of the client. However, administrators should verify that 9.1.15 is compatible with the specific version of the Pulse Connect Secure gateway they are running to ensure end-to-end security.
