All Specs Back in the early days of personal computers, you could install a security suite on the lone family computer in the den and be done. In the modern world, you have a houseful of devices that all need protection, whether they're running Windows, macOS, Android, or iOS. F-Secure Safe supports all four platforms, but it offers fewer protective features than the best competing products. In previous years, the F-Secure product line included a standalone antivirus, an entry-level suite called F-Secure Internet Security, and the cross-platform suite F-Secure Safe, reviewed here. F-Secure has dropped the entry-level suite for new installations, though existing users can keep it. Dropping it makes sense, given that its pricing was the same as the more powerful F-Secure Safe.
