Legacy operating systems that have reached end-of-support often lack security features and updates that are present in newer systems, making them targets for exploitation by adversaries. However, organizations within industries such as manufacturing and healthcare often need to run endpoints with these operating systems for specialized systems, including machinery and medical devices.

Endpoints in operational technology (OT) environments can be difficult and prohibitively expensive to upgrade or replace, resulting in devices being left unsecured or requiring additional security solutions and mitigations.

Comprehensive protection for legacy Windows and Linux endpoints

Introducing Sophos Endpoint for Legacy Platforms — a solution that provides comprehensive next-gen security for a range of Windows and Linux operating systems beyond the standard end-of-support dates provided by platform vendors.

Simplify deployment and management of endpoint security across all devices. Security solutions that limit support to modern operating systems drive organizations to deploy separate solutions for legacy systems, introducing a management burden on IT and security teams. Sophos provides industry-leading endpoint security for both legacy and modern platforms in Sophos Central — a powerful, cloud-based management platform that unifies all Sophos next-gen security solutions.

Protect critical devices beyond operating system vendor support timeframes. Defer difficult and costly upgrades for specialized systems. Sophos Endpoint for Legacy Platforms enables organizations to protect a range of legacy Windows and Linux operating systems beyond standard end-of-support dates offered by platform vendors.

Legacy systems protected by next-gen technologies. Web, application, and peripheral controls reduce the threat surface and block common attack vectors on legacy and out-of-support devices, while deep learning AI models protect against both known and never-before-seen attacks. CryptoGuard anti-ransomware and anti-exploitation technologies stop threats fast, so resource-stretched IT teams have fewer incidents to investigate and resolve.

Neutralize sophisticated attacks that can’t be stopped by technology alone. Legacy devices are attractive targets for exploitation by adversaries. Sophos’ AI-powered EDR and XDR tools enable organizations to detect, investigate, and respond to suspicious activity across all devices, including legacy platforms. Organizations with limited in-house resources can engage industry-leading Sophos MDR services to monitor and respond to threats across the entire IT environment.

Legacy systems deserve industry-leading security

Don’t risk the security of your legacy devices with inferior solutions. Devices running out of support operating systems are often critical to an organization. That’s why at Sophos, we believe these systems deserve the strongest protection, from a proven, market-leading endpoint security vendor.
