And with Dell deployment services options, it comes as only Dell brings it to you: Customizable to meet specific needs so you can reduce operational costs, help increase productivity and be ready for what's next.

Advanced Remote IT Management

The Dell OptiPlex 755 offers enhanced management and control with Intel® vPro™ processor technology, allowing IT staff excellent flexibility, high efficiency and reduced desk-side troubleshooting. So you can get more done around the office without having to run around - and you have more time for projects that can help an enterprise work better, faster and more efficiently.

  • Intel vPro Processor Technology. Designed to help reduce IT costs with simple, remote management from the IT console, Intel vPro helps extend management and protection. So you can turn desktops on and off remotely, do more remote troubleshooting, and protect your system through virtual, 'always-on' security. And Dell offers vPro on every OptiPlex 755 form factor* so you can get it where you need it, across the enterprise.
  • Industry standard-ready hardware management helps make systems management easy, highly efficient and secure with encrypted communications between the management console & client (versus ASF 2.0)
  • Dell Client Manager is available for download at no cost for Dell customers. This management console allows IT to take advantage of the advanced management features available on the OptiPlex 755, including secure remote power control, streamline provisioning and software patching, monitoring hardware with pre-defined alerts, remote troubleshooting and repair.
