USB Device Control Built for MSPs

Why MSPs Need a Dedicated USB Control Tool

Managed service providers handle endpoint security for dozens or hundreds of client organizations simultaneously. USB devices remain one of the most common vectors for data exfiltration and malware introduction — yet most RMM and endpoint platforms either lack USB control entirely or bury it behind complex configuration that doesn't scale across multiple tenants.

When a client suffers a data breach from an unauthorized USB drive, the MSP gets the call. PortGuard gives MSPs a purpose-built tool to enforce USB policies proactively across every client — before the breach happens, not after.

Common MSP Challenges with USB Security

How PortGuard Works for MSPs

1. One Console, Every Client

PortGuard's multi-tenant architecture lets you manage USB policies for every client organization from a single login. Switch between client tenants instantly. Each client's devices, policies, whitelists, and audit logs are completely isolated — no data crosses tenant boundaries. Your technicians see only the clients they're authorized to manage.

2. Deploy in Minutes, Not Hours

The PortGuard agent is under 4 MB and installs silently. Deploy it through your existing RMM tool — ConnectWise Automate, Datto RMM, NinjaOne, Syncro, or any platform that supports MSI/EXE deployment. Each client gets a unique tenant key baked into the installer, so endpoints automatically register to the correct client tenant. No manual mapping, no post-install configuration.

3. Per-Client USB Policies

Every client gets their own USB policy tailored to their business. Block all USB storage for the accounting firm. Whitelist encrypted drives for the engineering company. Allow specific vendor hardware IDs for the medical practice's approved devices. Policies are set per client, per machine, or per device — as granular as the situation requires.

4. Real-Time Enforcement Across All Sites

When you update a USB policy, the change reaches every affected endpoint in under one second via MQTT push — regardless of client location. No VPN required. No waiting for agent polling intervals. If a client calls about a USB incident, you can lock down their entire fleet from your desk before the conversation ends.

5. Audit-Ready Compliance Evidence

Every USB device connection attempt across every client is logged with device type, hardware ID, vendor, serial number, timestamp, machine name, and enforcement action. When a client's auditor asks for proof of USB media controls, export the log for that specific tenant. The data is always ready — no report building, no manual collection from individual machines.

MSP Client Scenarios

Why MSPs Choose PortGuard Over Alternatives

vs. Group Policy (GPO)

GPO-based USB blocking only works on domain-joined machines, requires Active Directory infrastructure at the client site, and offers no central visibility across clients. For MSPs managing diverse environments — many without a domain controller — GPO is impractical. PortGuard works on domain-joined and standalone machines equally, with a single cloud console for all clients.

vs. Endpoint Protector / AccessPatrol

Traditional USB control products require on-premise management servers. For an MSP, that means deploying and maintaining a server at every client site — or running a multi-server infrastructure in your own data center. PortGuard eliminates all server infrastructure. It's SaaS with native multi-tenancy designed specifically for the MSP model.

vs. RMM Built-In USB Controls

Some RMM platforms offer basic USB blocking via scripted policies, but these lack real-time enforcement, device whitelisting, and proper audit logging. They're workarounds, not purpose-built USB control. PortGuard provides the dedicated functionality that RMM USB scripts cannot: instant policy push, hardware-level device identification, and compliance-grade audit trails.

Adding Revenue with USB Security Services

USB device control is a natural upsell for MSPs already managing endpoint security. PortGuard's pricing makes it easy to build margin:

• Your cost: $2–$8/device/month depending on plan tier
• Client billing: Most MSPs include USB control in their security stack at $3–$15/device/month as part of a managed security bundle
• Zero infrastructure cost: No server hosting, no database licensing — pure margin after the per-device cost
• Compliance value: USB control checks a box on HIPAA, PCI DSS, CMMC, and cyber insurance questionnaires that clients need documented

For a 500-device MSP practice on the Starter plan, PortGuard costs $1,000/month. Billed to clients at $5/device as part of a security bundle, that's $2,500/month in revenue — $1,500/month in pure margin with zero additional infrastructure overhead.

Deployment Workflow for MSPs

1. Sign up at app.portguard.tech — free for up to 5 devices, no credit card
2. Create client tenants in the console — one per client organization
3. Generate tenant-specific installers — each embeds the client's tenant key
4. Deploy via RMM — push the agent through ConnectWise, Datto, NinjaOne, or any RMM tool
5. Set per-client policies — block all, whitelist specific devices, or custom rules per machine
6. Monitor from one dashboard — USB events across all clients in real time

Most MSPs onboard their first client in under 15 minutes and roll out fleet-wide within a day.

Guard Suite: Expand Your Managed Security Stack

PortGuard is the first module in the Guard Suite — a growing family of lightweight endpoint security tools built on the same cloud-managed, multi-tenant agent architecture. Upcoming modules include DriveGuard (disk encryption enforcement), PatchGuard (Windows update compliance), and AssetGuard (hardware/software inventory). Each module deploys through the same agent, manages from the same console, and inherits the same multi-tenant isolation — giving MSPs more tools to sell without more infrastructure to maintain.
