Ivanti Security Appliance ISA6500 & ISA8500

Overview

Protecting access to corporate information remains essential as organizations manage and secure users across hybrid environments. Ivanti Security Appliance (ISA) helps IT and Security teams deliver trusted access to applications and resources—no matter where they run—so you can manage, automate, and protect what matters most.

Purpose‑built for Ivanti advanced security services, the ISA series now includes new ISA6500 and ISA8500 hardware appliances, engineered with modern OS hardening (Oracle Linux 9, SELinux, NGINX with built-in WAF, and UEFI/GPT), TPM‑enabled integrity, and updated components such as DDR5 memory and NVMe storage options on ISA8500 and cloud deployments. These enhancements strengthen reliability, security, and serviceability for today’s hybrid IT implementations.

Whether your organization needs a fully featured Layer 3 VPN using a Unified Ivanti Secure Access Client (ISAC), clientless/browser‑based access to internal web-based resources and VDI / RDP / SSH / VNC access via HTML5 at Layer 7 and per-app or application level access using Layer 4 VPN tunneling, or a powerful policy‑based network access control gateway, ISA X500 series delivers consistent performance and protection for every device connected to on-premise or cloud networks.

For centralized control and visibility of ISA deployments, Ivanti recommends Neurons for Secure Access (NSA), a SaaS management and analytics platform.

ISA6500 and ISA8500 are fully compatible with Ivanti Connect Secure License Server for easy centralized user licensing and In-Case-Of-Emergency (ICE) for on-demand burst licensing.

ISA6500 and ISA8500 appliances ship with Ivanti Connect Secure 25.x, enabling modern platform capabilities and security hardening not available on earlier releases. Regional manufacturing facilities in California, Ireland and Taiwan supports predictable lead times and in‑theater fulfillment, and region‑aligned service operations.

Secure access–ready platform

ISA6500 and ISA8500 are engineered for next‑generation secure access, combining updated hardware designs with a modern OS foundation grounded in Ivanti’s Secure by Design and Secure by Default principles to deliver hardened, reliable connectivity across hybrid environments. With multiple deployment options for physical, virtual or cloud deployments, the ISA series can grow organically and dynamically with an organization’s secure access needs.

Dynamic capacity options for organizations of any size

The ISA X500 series can scale to match any organization’s needs, from SMB to large enterprise. With performance increases through software and kernel optimizations, ISA X500 series can scale more readily to an organization’s requirements.

Cloud‑deployment ready

ISA X500 series continue to offer physical, virtual, and cloud options. ISAs support deployment into Amazon Web Services, Microsoft Azure and Google Cloud Platform. ISA-V images can be found on the cloud marketplace for each vendor, and Ivanti provides deployment templates and detailed instructions to make your deployment go as smoothly as possible.

Enhanced user experience

A modern user portal, multi‑language support, MFA/SSO, and clientless access help deliver a smoother and more secure experience for global teams. Software improvements in 25.x enhance overall responsiveness and security.

Centralized management and analytics

Neurons for Secure Access is an optional centralized management and analytics platform that provides a single pane-of-glass interface for managing multi-node ISA deployments. Neurons for Secure Access provides gateway lifecycle management, user behavior analytics, configuration management and custom reporting tools.

Simplify deployment

With updated hardware designs and regional manufacturing, ISA6500/8500 help reduce operational overhead, while supporting predictable delivery schedules.

Increase performance

Modern components — including DDR5 memory, platform hardening, and optional NVMe storage on ISA8500 — deliver faster, more consistent responsiveness across ISA solutions, with ISA6500 achieving up to a 1.5x performance gain.

Data center & cloud

Deploy ISA as physical hardware today and extend secure access and policy consistency into virtual or cloud environments as updated virtual appliances become available.

ISA hardware appliance

ISA series hardware is designed to be a simple plug-and-play hardware solution for your organization’s Ivanti Connect Secure gateway needs.

Cutting-edge performance

ISA6500 and ISA8500 introduce next‑generation Intel® platforms with a 1.5x performance gain on ISA6500. Featuring 10 GbE interfaces for blazing fast connectivity, ISA x500 series hardware appliances are purpose-built to deliver the connectivity and speed users expect.

Security enhancements

ISA hardware features a modern OS foundation (Oracle Linux 9, SELinux, secure boot, UEFI/GPT) combined with TPM‑enabled integrity helps safeguard system components and enforce a strong security baseline to keep an organization’s network assets safe.

Lower TCO

Compact 1U appliances built for efficiency, stability, and simplified operations—paired with transferable subscription licensing—help reduce long‑term operational costs without adding management complexity.

Maximize uptime

Redundant hot‑swappable power supplies (ISA8500) and serviceable storage options are designed to reduce disruption and maintain user access during maintenance or replacement events.
