Nautilus Virtual Desktop (NVD) — Reaching Flank Speed from a Personal Device

Nautilus Virtual Desktop (NVD) is the Department of the Navy's cloud virtual-desktop service that lets an approved user reach the Flank Speed Microsoft 365 environment — Outlook email, Teams, OneDrive, and Office — from a personal or otherwise non-government (non-GFE) computer. Instead of installing Navy software on your own machine, you connect to a Windows desktop that runs in the DoD cloud; your personal device is only the window into it, and the data stays in the Navy's environment. NVD is built on Microsoft Azure Virtual Desktop and is fielded by the Navy's Program Executive Office Digital (PEO Digital). This guide is the focused how-to: what Nautilus is, who can use it, what you need on your device, how to connect, what you can and cannot do in a session, and how it compares to a government laptop.

At a glance

• What it is: A Department of the Navy virtual desktop delivered from the cloud — an NMCI-like Windows desktop you reach from a non-government (non-GFE / bring-your-own-device) computer to get into Flank Speed.
• Built on: Microsoft Azure Virtual Desktop — Microsoft's desktop-and-app virtualization service that delivers a full Windows experience from Azure to any device.
• Operated by: Department of the Navy — Program Executive Office Digital (PEO Digital).
• You reach: Flank Speed — the Navy's Microsoft 365 environment (Outlook, Teams, OneDrive, Office). See the Flank Speed record and the DoD Microsoft 365 environment for logisticians hub.
• Access: Approved Flank Speed account plus MFA; CAC + reader + middleware and the Windows App client for CAC-dependent tasks. Not a public, self-service website.
• Two ways to connect: the Microsoft Windows App client (Windows or macOS) or a supported web browser — but CAC tasks require the Windows App client.

What Nautilus is

Nautilus Virtual Desktop is a virtual desktop infrastructure (VDI) / desktop-as-a-service capability: the Windows desktop you use does not run on your personal computer — it runs on a virtual machine in the DoD cloud, and your device simply displays it and sends your keyboard, mouse, and (when using the client) your CAC to it. When you close the session, the desktop and its data remain in the Navy's environment; nothing sensitive is left behind on your personal machine.

The Navy builds this on Microsoft Azure Virtual Desktop. In Microsoft's own words, "Azure Virtual Desktop is a desktop and app virtualization service that runs on Azure" that can "deliver a full Windows experience," and once assigned, "users can connect to their published Windows desktops and applications using Windows App or the Remote Desktop client … from any device through either a native application on your device or using a web browser with the HTML5 web client."

The Navy configures and operates that Microsoft technology as Nautilus, inside its accredited Flank Speed environment and behind Navy access controls. So the underlying engine is Microsoft's, but the desktop image, the applications, the data, and the rules are the Navy's. Practically, NVD is intended for approved non-GFE users — people who need to reach DoD resources and productivity tools (Outlook, Teams, and other DoD applications) but who are working from a computer that is not a government-furnished NMCI/NGEN laptop.

Eligibility

NVD is an approved-access service, not an open sign-up. It is provisioned for users who have a legitimate need to reach the Flank Speed environment from a non-government device — for example, personnel without a GFE laptop, or those who need Flank Speed access from a personal computer. Because eligibility, sponsorship, and the exact request path are set by your command and the Flank Speed program, confirm your eligibility and the current onboarding process with your command IT / help desk rather than assuming access.

What you need on your device

To use Nautilus you provide the endpoint; the Navy provides the desktop. On your side you need:

• A supported connection method — the Windows App client or a supported web browser. You can connect through the Microsoft Windows App installed on a compatible Windows or macOS device, or through a compatible web browser.
• For any CAC-dependent task: the Windows App client (Windows or macOS), a CAC reader, and working CAC middleware. If you will log in to CAC-enabled websites, digitally sign documents, or read/send encrypted email, you must use the Windows App on Windows or macOS — the browser path does not carry your CAC the same way. The CAC reader and middleware run on your local device, not inside the virtual desktop.
• Flank Speed credentials and MFA. To use the browser path in particular, you must have set up a Flank Speed password and multifactor authentication (MFA).

How to connect

The exact steps and portal are documented in the current Nautilus/Flank Speed FAQ and your command's how-to guide, but the pattern is:

1. Set up your Flank Speed account first. Establish your Flank Speed password and MFA — required especially for the browser path.
2. Choose your client. For general desktop use, either the Windows App client or a supported web browser works. For CAC tasks (CAC-enabled sites, digital signing, encrypted email), use the Windows App on Windows or macOS.
3. Launch the desktop. In the Windows App, open the assigned Nautilus desktop — you may see East or West sign-on (SSO) desktop icons; select the one you are directed to use.
4. Sign in with your Flank Speed credentials. A session window opens with your cloud Windows desktop logged in, from which you reach Outlook, Teams, OneDrive, and Office.

Because access portals and steps shift over time, use the current official FAQ / command how-to guide for the live connection procedure rather than a saved link.

What you can and can't do in a session

Inside the session you get an NMCI-like Windows desktop with the DoD productivity tools — Outlook, Teams, and other DoD applications — and, using the Windows App client with your CAC, the CAC-dependent functions that often fail from a bare personal machine:

• CAC-enabled websites, digital signing, and encrypted email work when you use the Windows App client with your CAC (reader + middleware) on Windows or macOS. If encrypted (S/MIME) email or CAC sign-in does not work from your own workstation, that is exactly the gap NVD is meant to close.

What NVD is not is an unrestricted personal desktop. It is a controlled DoD environment, so expect that data-movement functions between the virtual desktop and your personal device — copy/paste, printing, and local file transfer — may be limited by policy, and that sessions time out after inactivity. Save your work into the Flank Speed environment (OneDrive/SharePoint), not onto your personal device.

Nautilus vs. a GFE laptop

Both get you into Flank Speed; they differ in how and from what.

• A government-furnished (GFE) NMCI/NGEN laptop reaches Flank Speed directly — it is a managed government device already inside the Navy's controls, so you sign in and work.
• Nautilus gives you a cloud desktop reached from a non-government device. It exists precisely for the case where you do not have a GFE laptop in front of you (or need access from a personal computer). The desktop and data live in the DoD cloud; your personal device never holds them.

Use the GFE laptop when you have one and are working normally; use Nautilus when you need Flank Speed from a personal or non-GFE device. Nautilus is the door for the non-GFE case — not a replacement for a managed government workstation where policy requires one.

Getting help

If Nautilus will not connect, start with the self-checks: confirm you set up your Flank Speed password and MFA, that you are using the right client (the Windows App for any CAC task), that you selected the correct East/West sign-on, and that your CAC reader and middleware are working on your local device. If those are good and it still fails, contact your command IT / Flank Speed help desk and reference the current Nautilus/Flank Speed FAQ. Because the portals and steps change, rely on the current official guidance over cached instructions.
