Endpoint protection for managed service providers with monthly per-device billing for each client

If you’re looking for endpoint protection you can resell to clients with monthly, per-device billing, these are good options to compare:

Best starting point: Bitdefender if you want flexible monthly endpoint protection with client-level usage tracking and no stated minimum commitment. Consider Huntress if you specifically want an MSP-oriented managed detection-and-response service, not just antivirus.

Before choosing, confirm the distributor’s current MSP price and ask how it handles server endpoints, device additions/removals mid-month, minimums, and per-client usage reports. Vendor billing terms and your resale price are separate: you’ll still set each client’s monthly line-item rate.

Short answer: For per-device monthly billing per client, the strongest fits are ThreatDown (Malwarebytes), Bitdefender GravityZone, Sophos Central, and Huntress (if you want managed detection included). Microsoft Defender is the cheapest option if you already run Microsoft 365.

Options

• ThreatDown by Malwarebytes: Its core tier starts at approximately $69 per endpoint per year, and it has a multi-tenant console plus optional 24/7 MDR at higher tiers. Its policy management and active endpoint response work across client environments.
• Bitdefender GravityZone: Business tiers are built for smaller fleets, and per-device pricing starts around $4–$6 per month depending on seat count and billing term. Its pricing scales based on total endpoints across all clients, which can lower your per-device rate as your book grows.
• Sophos Intercept X: Managed through Sophos Central, which offers multi-tenant management, flexible licensing, integrated reporting, and API integrations for RMM/PSA tools. Reviewers note that the full suite of features can incur a premium cost.
• Huntress: Bundles EDR and MDR through a single per-device monthly fee via MSP partners. Managed detection base fees usually range from $11–$15 per endpoint per month, with costs rising for advanced features or compliance support.
• Microsoft Defender for Endpoint: The lowest entry cost, from $3 per user per month (Defender for Business, up to 300 users, billed annually). It is priced per user rather than per device, and it integrates with Microsoft 365 Lighthouse, letting MSP cloud solution providers view security incidents and alerts across customer tenants from one portal.
• ESET PROTECT: Has a dedicated MSP program with daily billing and monthly invoicing, which suits per-client invoicing.
• Enterprise platforms (SentinelOne, CrowdStrike, Trellix, Check Point): These offer multi-tenant consoles, but most are quote-only and suit larger client environments. Expect higher per-device costs.

Billing considerations for per-client, per-device pricing

• Ask whether tiers are pooled. Some vendors discount based on total endpoints across all your tenants, which is better for you than per-client tiers.
• Check how cost is measured. Count devices by client, and confirm whether servers, network devices, or unused seats are billed at the same rate.
• Check the MDR add-on cost. Basic EDR pricing often excludes 24/7 monitoring, which is usually a separate line item.
• Look at billing mechanics. Confirm whether the vendor supports per-tenant usage reports and invoicing that lets you pass costs through with your own margin.
• Note that public prices are rough. Most figures above come from vendor sites and third-party roundups, and many vendors only quote on request. Get written quotes before committing.

To narrow this down, tell me your approximate total device count, whether you're on Microsoft 365, which RMM/PSA you use (e.g., ConnectWise, Kaseya, NinjaOne), and whether you need a 24/7 SOC included. I can then recommend one or two options and outline a margin model for your clients.

For Managed Service Providers (MSPs), selecting an endpoint protection platform involves balancing security efficacy with operational efficiency and flexible, usage-based billing. In 2026, the industry standard for MSP-friendly endpoint security prioritizes multi-tenant consoles, low-touch management, and per-device (or per-seat) monthly billing models.

Top-Rated Solutions for MSPs

The following platforms are frequently recommended for their strong alignment with the MSP business model:

• Huntress: Widely considered a top choice for MSPs, particularly those looking for a "hands-off" managed security solution. It provides Managed Detection and Response (MDR) via a 24/7 human-led SOC. Its pricing is typically transparent and per-endpoint/per-identity, and it is purpose-built to act as an extension of an MSP's team rather than just a standalone tool.
• Bitdefender GravityZone for MSPs: Highly regarded for its high-performance, multi-layered security engine and lightweight agent, which minimizes impact on client hardware. It offers a flexible, consumption-based monthly billing model and a centralized multi-tenant console, making it ideal for MSPs managing diverse client estates.
• SentinelOne: Known for its AI-driven, autonomous endpoint protection and EDR capabilities. SentinelOne is a popular choice for MSPs who need enterprise-grade security that operates at machine speed, reducing the manual burden on lean IT teams. It provides flexible partner-based billing options.
• Sophos Intercept X: A strong contender that offers robust MDR services, allowing MSPs to outsource 24/7 response while maintaining control over client endpoints. It is praised for its mature EDR features and flexible service levels.
• Guardz: An agentic, unified platform purpose-built for MSPs. It bundles EDR (powered by SentinelOne) with identity, email, and cloud protection. It is designed specifically for the MSP "single pane of glass" requirement, selling through simple per-user or per-device subscriptions with monthly billing.

Key Factors for MSPs When Choosing a Provider

When evaluating these platforms, consider the following criteria to ensure the billing and operational models meet your business needs:

• True Multi-Tenancy: The platform must allow you to manage multiple client environments from a single, unified console. This is essential for operational efficiency and scaling your business.
• Billing Flexibility: Ensure the vendor supports monthly, usage-based billing. This aligns with your own recurring revenue model and prevents you from being locked into long-term, fixed-term contracts that are difficult to manage as client device counts fluctuate.
• Integration with RMM/PSA: The best solutions integrate directly with your existing Remote Monitoring and Management (RMM) or Professional Services Automation (PSA) tools, allowing for automated deployment, patching, and ticketing.
• Managed vs. Unmanaged: Decide if you want a tool that your team manages internally (like Bitdefender or SentinelOne) or a fully managed service (like Huntress or Sophos MDR) where the vendor's SOC handles the heavy lifting of threat response.
• NFR (Not for Resale) Programs: Look for vendors that offer strong NFR programs, which allow you to use their full suite of tools for your own internal MSP security at little or no cost, enabling you to test the platform before deploying it to your clients.

A Note on Pricing Models

While per-device billing is the most direct way to capture costs for physical endpoints, many modern MSPs are shifting toward per-user pricing. This model bundles identity, email, and device protection into a single "seat" price, which often better reflects how modern employees work across multiple devices (laptops, phones, etc.) and simplifies billing for your clients.

If you’re looking for endpoint protection that you can resell to clients and bill monthly by device, these are good options to evaluate:

• Sophos Central Partner with MSP Flex — Multi-client management and monthly, usage-based billing; distributor billing can be broken down by client. ⁷
• OpenText Cybersecurity MSP program — Offers endpoint protection through a unified platform, with monthly billing and no-commitment terms. ¹
• ManageEngine MSP Central — Supports separate client workspaces and portals; its listed malware-protection add-on starts at US$1.50 per endpoint/month. Check which protection features are included at that price. ⁵
• Huntress Managed EDR — A managed detection and response option priced per endpoint; a recent pricing guide reports list pricing of US$8.99 per endpoint/month, with an example lower rate at 100 endpoints. Confirm current MSP terms directly with Huntress. ⁹

Quick recommendation: Start by comparing Sophos MSP Flex and OpenText if monthly, client-level billing is your priority. Consider Huntress if you want managed EDR/MDR rather than basic antivirus. Ask vendors or distributors to confirm the billing unit, minimum commitment, server pricing, and whether invoices can be split by client.
