Microsoft Windows 7 (all versions) with Service Pack 1 (SP 1) or later.Operating Systems Supported (Norton Security 22.16.0.247 for Windows).In April 2019, the Norton 360 brand was reinstated, maintaining a similar plan structure but with the addition of VPN and, on the premium tiers, LifeLock (which was acquired by Symantec in 2017).

However, features may vary based on the operating system. All editions include protection for Windows, OS X, Android and iOS devices. Norton Security is available in three editions: Norton Security Standard with one license (valid for a single device), Norton Security Deluxe with five licenses and Norton Security Premium which offers ten licenses, 25 GB of hosted online backup, and a premium subscription to Symantec's parental control system. In terms of similarities and differences with its predecessors, Norton Security retained all components of Norton Internet Security (including the antivirus, firewall and identity theft components) and added the optimization tools from Norton 360. However, version 22 of Norton 360 and Norton Internet Security were updates as opposed to full releases. Norton Security superseded Norton Internet Security (and the pre-2019 versions of Norton 360), with an overlapping release cycle that saw version 22 as the initial release of the former and the final release of the latter. In 2014, in an effort to streamline its Norton product line, Symantec combined nine standalone Norton products into one all-purpose suite.
