The HP 5y Wolf Pro Security 1-99 E-LTU (U86NWAAE) is an electronic licence for HP Wolf Pro Security, HP's endpoint protection service for small and medium businesses, covering one device for five years including licence and support. The 1-99 in the name is HP's purchase band: this part number applies when buying between 1 and 99 licences. Wolf Pro Security is designed for companies without a large IT security team and combines next-generation antivirus with HP's isolation technology, which opens risky content such as email attachments, downloads and web links in contained virtual machines so malware cannot reach the PC. It is delivered as a download (e-LTU, no physical media) and runs on 64-bit Windows 10 and Windows 11 Pro and Enterprise, including LTSC editions. Supported language packs include English, French, German, Spanish, Swedish, Italian, Brazilian Portuguese, Japanese and Dutch. Because it is a licence there is no physical product to ship.
