Unattended Access Deployment: Scale to Hundreds

Rolling out unattended access to hundreds of machines without visiting any of them is the obvious goal — and the headache that follows if you skip planning. This guide walks through a reproducible, auditable rollout: build preconfigured installers, push them via GPO/MDM or orchestration tools, validate at scale, and avoid common pitfalls. If you already know your environment's constraints (air-gapped, strict residency, or compliance that forbids third-party relays), skip straight to the self-host section below.

1. Decide architecture and prerequisites

Before packaging anything, choose whether the fleet will use Tenvo's managed relay or a self-hosted relay. Tenvo's managed relay is our default recommendation: it provides multi-region failover, a browser client (public beta), native clients for Windows/macOS/Linux, and pricing tiers Free $0 / Lite $2.99/mo / Pro $7.99/mo. Use Tenvo's relay unless you have a written requirement to run your own (data residency, an isolated network, or a compliance rule that prohibits third-party infrastructure). Managed relays reduce on-call burden: you don't run TLS termination, certificate renewal, key custody, or single-region failover.

Security note: Tenvo uses mutually authenticated TLS with a per-device certificate. A direct peer-to-peer connection between two devices is end-to-end between those endpoints; when traffic falls back to a relay, TLS terminates at the relay, so whoever operates that relay can access session traffic. Plan your logging and access controls accordingly.

2. Build preconfigured installers

Preconfigured installers remove human error. The installer should install the service, drop the configuration file or token in the right path, and start the service. Common platforms and their recommended formats:

• Windows: MSI or EXE with silent switches (msiexec /i mypkg.msi /qn).
• macOS: .pkg or a signed installer using installer CLI.
• Linux: .deb/.rpm packages with systemd service enablement.

Design the installer so that a single, reproducible artifact can be pushed to hundreds of machines and will register the machine with your console automatically. The configuration should include: a device name template, an install token or provisioning key, and runtime options (auto-start, user-session behavior, logging level). Never bake long-lived admin passwords into installers — use per-device tokens or short-lived bootstrap tokens that the management console can revoke.

Example: Windows installer workflow

REM Example: unattended install and provisioning (Windows PowerShell)
msiexec.exe /i TenvoAgent.msi /qn /norestart
# Copy config (JSON) to ProgramData before starting service
Copy-Item -Path .\tenvo-config.json -Destination 'C:\ProgramData\Tenvo\config.json' -Force
Start-Service -Name TenvoAgent

Example: what the JSON config might contain (keep secrets minimal):

{
  "provisioning_token": "PROV-TOKEN-PLACEHOLDER",
  "device_name": "{hostname}-{serial}",
  "auto_start": true,
  "log_level": "info",
  "relay_region": "auto"
}

For macOS a similar flow can be scripted with pkgbuild/productbuild and the installer CLI; for Debian/Ubuntu, include postinst that places the config and enables the systemd unit.

3. Push methods at scale: GPO, Intune, SCCM, and SSH

Choose the deployment channel your environment already trusts. Don’t invent a new distribution method during the rollout. Here are the common approaches with practical tips.

Windows: Group Policy (GPO) or Intune

• GPO (AD): Use Group Policy Software Installation (assign the MSI) for domain-joined machines. Assign, don't publish, so the agent installs on boot. Test on a small OU first. If you need to place a config file, use Group Policy Preferences to copy the JSON into ProgramData after install, then configure a startup script to start the service.
• Intune: Wrap the MSI as a Win32 app, include the config as a dependency or install script, and mark the app as required. Use detection rules that check the service exists or that a file exists at C:\ProgramData\Tenvo\installed.tag.

SCCM / Endpoint Configuration Manager

Use an application package with a detection method that checks the service state. Deploy in rings: 1% canary, 10% pilot, then 50/90. Use compliance baselines to verify the config file matches the expected content (token is present; device_name template is correct).

Linux & macOS: SSH, MDM, and management agents

• Linux: If you have SSH access, push the package and config with a script that runs apt/apt-get or rpm/dnf. For fleets managed by configuration management (Ansible/Chef/Puppet), make the agent a managed resource so it is enforced by your CM tool. Example: an Ansible task that copies config and restarts service.
• macOS: Use Apple MDM (Jamf, Intune macOS) to deploy a signed .pkg and a configuration profile. If MDM cannot write the config file directly, use a postinstall script inside the package.

Device naming and inventory

Decide on a deterministic device-name template (facility-hostname-serial) to avoid duplicates. If the agent supports tags or groups, include department and location at install time — this helps filter and roll back problem batches. Export a CSV of device identifiers before deployment so you can cross-check which machines reported in.

4. Canary, validation, and rollbacks

Don’t deploy everywhere at once. Use a rolling strategy with automated verification at each step. Example ring sizes: Canary 1–5, Pilot 5–50, Production waves 10–25% each. For a fleet of 1,000 machines, a reasonable rollout could be 5 canary, 45 pilot, then 200/200/250/300 waves depending on tolerance for risk.

Validation checklist for each wave:

• Agent service is running (service status check or systemd unit active).
• Device appears online in the management console.
• Console shows correct device metadata (name, tags, OS).
• Perform a test session to one canary device to verify screen, input, and file transfer if used.
• Check application logs for errors (e.g., TLS handshake failures, provisioning rejections).

Automate checks where possible. A simple script can query the Tenvo API (or console) for device status and mark a wave green if >=95% success, otherwise pause and investigate.

5. Monitoring, logs, and auditability

At fleet scale you'll need visibility into installs and runtime health. Ensure:

• Install logs are centrally collected (Syslog, Windows Event Forwarding), with entries that include a deployment ID so you can map an install batch to a result.
• Agent logs are on a retention schedule and rotated; for compliance, capture who initiated remote sessions and when.
• Alerting for repeat failures: e.g., if >2% of a wave reports a provisioning error, trigger a human review.

Design your audit trail before the rollout: deployments, who created provisioning tokens, and device ownership should be recorded. If you need to meet standards like SOC 2 or PCI, map your remote-access logs to those control requirements in advance. See Remote Desktop Audit Logging for patterns on what to capture.

6. Certificate and token lifecycle

Don’t forget key rotation. Provisioning tokens should be short-lived or rotatable, and you must have a plan to revoke tokens for decommissioned devices. For relays, plan certificate renewal and monitor expiry dates: when a relay certificate expires, connected devices may fail TLS handshakes until refreshed.

Practical policy: rotate provisioning tokens every 90 days for large fleets, or use per-device tokens that you can revoke individually. If you self-host the relay, list the people who can renew certificates and automate renewal with a documented runbook. If you use Tenvo's managed relay, certificate renewal is handled by Tenvo; you still own your device tokens and can revoke them from the console.

7. When to self-host a relay (and what breaks)

Self-hosting is the right call only when a written requirement forces it: a compliance obligation barring third-party infrastructure, an isolated network with no egress, or a hard data-residency rule. Otherwise, a managed relay typically costs less when you tally on-call time, patching, key custody, certificate renewal, and lack of multi-region failover.

If you must self-host, plan for:

• HA across regions (or at least multiple AZs) to avoid single-region failure.
• Monitoring and automated cert renewal (let's encrypt or your CA) with tracking and alerting.
• Backups of configuration and private keys, plus strict access control and rotate credentials.

8. Common failures and how to fix them

Failures cluster around networking, permissions, and provisioning. Troubleshoot with this prioritized checklist:

1. Service not running: check systemd/Windows service logs and permissions. On Windows, check Event Viewer for the install package code. Ensure the service account has rights to the config path.
2. Agent can't reach relay: confirm outbound HTTPS (443) is allowed to the relay endpoints, and that company proxies are configured. Some corporate proxies require NTLM/kerberos auth and need explicit agent proxy configuration.
3. Name or token mismatch: verify the installed config has the expected provisioning token. If your deployment places the token via a post-install script, check file copy order (file should exist before the service starts).
4. TLS handshakes failing: look at agent logs for certificate errors. If you're self-hosting, check chain validity and that intermediate certs are present. If using Tenvo's managed relay, verify relay region settings.
5. Devices appear offline in console: check heartbeat intervals and firewall stateful rules that may drop long-lived connections. Increasing agent keepalive or changing relay region can help in flaky networks.

9. Rollout checklist (one-page)

• Pick managed relay vs self-host (document reason).
• Create provisioning tokens and tag policy.
• Build a single preconfigured installer per OS and verify silent install switches.
• Test install on three machine types (canary farm).
• Deploy pilot wave with health checks automated.
• Monitor logs and device count; pause if failures exceed threshold.
• Progress waves and document rollbacks (uninstall script or token revocation).

10. Example PowerShell bootstrap for Windows (practical)

# Bootstrap script for a silent Tenvo install on Windows
$msiPath = "\\fileserver\packages\TenvoAgent.msi"
$configPath = "\\fileserver\configs\tenvo-config.json"
Copy-Item $msiPath -Destination "C:\Temp\TenvoAgent.msi" -Force
msiexec.exe /i "C:\Temp\TenvoAgent.msi" /qn /norestart
New-Item -ItemType Directory -Force -Path 'C:\ProgramData\Tenvo'
Copy-Item $configPath -Destination 'C:\ProgramData\Tenvo\config.json' -Force
Start-Service -Name TenvoAgent
# Wait and verify
Start-Sleep -Seconds 10
if ((Get-Service -Name TenvoAgent).Status -ne 'Running') { Write-Error 'Tenvo service failed to start'; exit 1 }
Write-Output 'Install complete and agent running.'

Embed this into your deployment pipeline (SCCM/Intune/PSExec) and ensure the fileserver path is resolvable by target hosts. For Intune wrap the script into Win32 app install behavior and use detection rules that look for the service.

Final notes and truth-telling about cost

At fleet scale, the obvious metric isn't the per-device license alone — it's total operational cost. Self-hosting shifts effort into a full-time task: patching relays, certificate rotation, incident response, and backups. Tenvo's managed relay removes that operational weight. Our managed relay is multi-region, supports native clients for macOS/Windows/Linux, has a browser client in public beta, and comes in Free $0 / Lite $2.99/mo / Pro $7.99/mo tiers.

We try to be blunt: if your organization can accept a third-party relay and you want to minimize ops overhead and get multi-region reliability, use Tenvo's managed relay. If a regulation explicitly forbids external relays, follow the self-host checklist and plan for long-term maintenance costs.
