NinjaOne vs N-able vs Datto RMM for UK MSPs with 200–2,000 Endpoints — Tested with GBP Pricing

If you run a UK MSP and manage between 200 and 2,000 endpoints, your RMM platform is the single tool that touches every client, every day. Get it wrong and you burn technician hours on workarounds. Get it right and your margins improve without hiring. NinjaOne, N-able N-central, and Datto RMM are the three platforms that appear on nearly every UK MSP shortlist, yet none of them publish a straightforward price card in GBP. This article sets out what each platform actually costs at UK MSP scale, how their patching, automation, and backup capabilities compare, and where each one falls short — The global MSP software market now tops £300 million, with the PSA and RMM segments growing 14 per cent year-on-year. Choosing the wrong platform at this scale is not a trivial mistake — migration costs time, disrupts clients, and burns margin you cannot afford to lose. This comparison sets out the evidence so you can make a decision based on numbers rather than a sales demo.

Why These Three and Not the Others

ConnectWise Automate, Atera, and SuperOps all have their advocates, but NinjaOne, N-able N-central, and Datto RMM dominate the shortlist for UK MSPs between 200 and 2,000 endpoints for specific reasons. NinjaOne has held the number-one spot in the G2 RMM category for 23 consecutive quarters and reports a 98 per cent CSAT score. N-able N-central commands 16.2 per cent of the global MSP software market, second only to ConnectWise, and its scripting engine gives technical MSPs deep automation control. Datto RMM sits inside the Kaseya 365 bundle, which prices RMM, antivirus, EDR, MDR, patching, and endpoint backup at a single per-endpoint rate that undercuts standalone licensing. The combined PSA and RMM market grew 14 per cent year-on-year in Q2 2025, and the top five vendors — ConnectWise, Kaseya, N-able, NinjaOne, and Atera — now account for over two-thirds of the £300 million-plus global MSP software market. For UK MSPs specifically, the shortlist narrows further because UK-based support availability, GBP billing, and VAT handling matter. NinjaOne bills in GBP and has a UK sales presence. N-able works through UK distributors such as QBS and Brigantia. Datto RMM, now under Kaseya, operates through its established UK channel but billing has shifted since the acquisition, and some UK partners report longer invoice processing times.

What Each Platform Actually Costs

None of the three publishes a GBP price card, so every quote you receive will be tailored. That said, published benchmarks and community reports give you enough to negotiate from a position of knowledge rather than guesswork. All three vendors expect negotiation, and the best time to push for a discount is at the end of a financial quarter. Ask for a written breakdown of per-endpoint costs with and without optional modules so you can compare like for like across vendors.

NinjaOne prices per device, not per technician. At 200 endpoints you can expect to pay in the region of £2.50–£3.00 per endpoint per month. By 1,000 endpoints that drops to roughly £1.50–£2.00. There are no onboarding fees, no training charges, and unlimited support is included in the per-device rate. If you bundle RMM with NinjaOne's backup, patching, and documentation modules, you unlock additional volume discounts. NinjaOne adjusts pricing by region, so the UK rate tends to sit slightly below the published USD figures once converted.

N-able N-central also prices per endpoint, but the rate depends heavily on which modules you activate. The base RMM monitoring licence starts lower than NinjaOne for large estates, but once you add patching, remote access, and the security modules, the total per-endpoint cost climbs. N-able does not publish list prices and expects you to negotiate through a channel account manager. For a 500-endpoint MSP, community reports suggest a total cost in the range of £2.00–£3.50 per endpoint per month depending on the module stack.

Datto RMM is now sold primarily as part of Kaseya 365 Endpoint. The introductory bundle price was $3.99 (roughly £3.20) per endpoint per month for the Pro tier, which includes RMM, antivirus, EDR, MDR, patching, ransomware rollback, and 5 TB of shared endpoint backup. The Express tier without MDR started at $1.75 (roughly £1.40). After the introductory period, Pro rose to $5.25 (roughly £4.20) and Express to $2.25 (roughly £1.80). If you only need RMM and do not want the security stack, Datto RMM as a standalone product is harder to price because Kaseya is steering all new customers toward the bundle. Be aware that from December 2025, Kaseya ended its high-watermark pricing policy, so your bill now reflects actual endpoint counts rather than peak usage.

Patching and Automation Compared

Patching is where the bulk of RMM technician time goes for a typical MSP, so the differences here matter more than headline feature lists suggest.

NinjaOne handles Windows, macOS, and Linux patching natively, with over 200 third-party applications supported out of the box. Patch policies can be set per organisation, per device group, or per individual device, and the approval workflow lets you auto-approve tested patches while holding back anything flagged by the community. NinjaOne's automation engine uses a visual scripting builder alongside PowerShell, Bash, and Shell scripts, which means your junior technicians can build automations without writing code from scratch.

N-able N-central offers the deepest scripting engine of the three. Its automation manager supports complex multi-step workflows with conditional logic, loops, and error handling that go well beyond what NinjaOne or Datto offer. Third-party patching covers a similar range to NinjaOne, though some MSPs report that the patch approval interface feels dated compared to NinjaOne's dashboard. If your MSP employs engineers who think in PowerShell and want granular control over every automation step, N-central gives you that control. The trade-off is onboarding time. Expect to spend two to three weeks configuring N-central's automation manager to match your service delivery standards, compared to roughly one week for NinjaOne's more guided setup process.

Datto RMM covers Windows and macOS patching with reasonable third-party depth, but Linux support is limited compared to NinjaOne. The automation engine handles common monitoring and remediation tasks well, but for complex multi-step workflows you may find yourself reaching for external scripting tools. Datto's strength is its tight coupling with the wider Kaseya stack — if you also use Autotask PSA, the ticket-to-remediation pipeline is tighter than what you get with NinjaOne or N-able unless you build custom integrations.

Backup and Security Bundling

This is where the Kaseya 365 bundle changes the maths.

If you buy NinjaOne or N-able, you still need separate licences for endpoint backup, antivirus, and EDR. NinjaOne offers its own backup module that can be bundled, and N-able integrates with Cove Data Protection, but neither includes EDR or MDR in the RMM licence. You will need to add a separate security stack — Huntress, SentinelOne, or similar — which typically costs £2–£4 per endpoint per month on top of the RMM fee.

Kaseya 365 Endpoint bundles all of this into a single per-endpoint price. For an MSP that currently pays separately for RMM, antivirus, EDR, MDR, and backup, the bundle can cut the combined per-endpoint cost from roughly £10–£11 down to £3–£5. The trade-off is vendor lock-in. If you move away from Kaseya later, you are replacing not just your RMM but your entire endpoint security and backup stack in one go.

UK Support and Onboarding

For UK MSPs, support availability during GMT working hours matters more than a 24/7 promise answered from a timezone twelve hours away.

NinjaOne offers unlimited support included in every licence, with a published average response time of 65 minutes. Support is available via phone, email, and chat. NinjaOne's onboarding programme is free and includes dedicated onboarding engineers who walk your team through migration from your existing RMM. UK MSPs consistently rate NinjaOne's support as the strongest of the three.

N-able provides tiered support depending on your partner level. Higher-tier partners get faster response times and dedicated account managers. The support team operates globally, with UK-hours coverage available but not guaranteed for all tiers. Onboarding is handled through channel partners rather than directly by N-able, so your experience will vary depending on which distributor you work with.

Datto/Kaseya support has been a sore point since the acquisition. Community feedback suggests longer response times and less consistent quality compared to the pre-acquisition Datto experience. Kaseya has invested in improving this, but UK MSPs should verify current SLAs and test the support experience during any trial period before committing. During your trial, log a non-urgent support ticket on a Monday morning GMT and measure the response time. Then log an urgent ticket on a Friday afternoon. The difference between those two experiences tells you more about real-world support quality than any published SLA figure.

Five Questions to Ask Before You Choose

First, what endpoint count will you manage in 12 months, not just today? NinjaOne's per-device pricing scales smoothly, N-able rewards larger estates, and Kaseya 365's bundle value increases with endpoint count.

Second, do you need the security stack bundled or do you already have preferred security vendors? If you run Huntress or SentinelOne and have no intention of switching, the Kaseya 365 bundle loses much of its cost advantage.

Third, how technical is your engineering team? N-central's scripting engine is the deepest of the three, but only if you have engineers who will use it. If your team prefers visual automation builders, NinjaOne is the better fit.

Fourth, what PSA do you use? Datto RMM integrates tightly with Autotask. NinjaOne integrates with ConnectWise, Halo, and Autotask. N-able works best with its own N-able MSP Manager or ConnectWise.

Fifth, can you run a 30-day trial with real endpoints, not a sandbox? All three offer trials, but you will only discover the patching quirks, alert noise levels, and support responsiveness by running the platform against your actual client estate.

Sixth, what does it cost to leave? NinjaOne operates on monthly billing with no long-term contract requirement. N-able typically requires annual commitments with auto-renewal clauses that need cancelling 60–90 days before renewal. Kaseya 365 contracts vary, but community reports suggest 12–36 month terms are standard. Factor the exit cost into your total cost of ownership, not just the per-endpoint rate.

The Verdict for UK MSPs at 200–2,000 Endpoints

NinjaOne is the safest choice for the majority of UK MSPs in this range. Its pricing is transparent relative to the competition, its support is consistently rated the highest, and its patching and automation tools cover the needs of a typical managed services operation without requiring deep scripting skills. The main limitation is that you will need to source and pay for your security stack separately.

N-able N-central is the right choice if your MSP runs a technical team that wants maximum automation control and you manage enough endpoints to negotiate a competitive per-device rate. The platform rewards investment in scripting and automation, but the learning curve is steeper and the support experience is less consistent than NinjaOne. If you plan to grow beyond 2,000 endpoints within two years, N-central's pricing curve and automation depth may deliver better long-term value than NinjaOne at that scale.

Datto RMM inside Kaseya 365 is worth serious consideration if you want a single vendor for RMM, security, and backup, and you are comfortable with the vendor lock-in that entails. The per-endpoint bundle price is genuinely lower than buying each component separately, but you should stress-test the support experience and read the contract terms on the high-watermark policy change before signing.

To put the numbers in context: a 500-endpoint MSP paying separately for NinjaOne RMM (£2.25), Huntress EDR (£2.50), and a backup solution (£1.50) would spend roughly £6.25 per endpoint per month. The same MSP on Kaseya 365 Pro would pay £4.20, saving roughly £1,025 per month. Whether that saving outweighs the risk of single-vendor dependency is the central question.
