NinjaOne vs. Datto RMM: Which One Actually Fits Your MSP?
Paying eight times more for the same monitoring-and-patching job only makes sense if the rest of your stack actually uses the connection you're paying for. Here's how to tell.
Datto RMM costs 8x more than NinjaOne — the premium only pays for itself inside one specific ecosystem
Both platforms serve the same 5-500 employee range.
The RMM is the tool your technicians touch every single day, and it's also the widest price gap in the entire MSP stack — $75/mo versus $600/mo for the same core job of endpoint monitoring and automated patching. That gap isn't about scale or capability; both cover 5 to 500 employees identically. It's about which PSA and backup platform you've already committed to, because each of these two RMMs only fully pays off inside one specific ecosystem.
Monthly price comparison
NinjaOne: $75/mo — the ConnectWise-ecosystem RMM
Endpoint monitoring, automated patching, and scripting from a single pane of glass, priced low because NinjaOne isn't trying to anchor a bundled PSA-and-backup business the way Datto/Kaseya does — it's sold closer to a la carte. The failure mode: assuming it reconciles automatically with Datto SIRIS backup jobs because "most RMMs just do that." It doesn't list that integration; the pairing that actually works natively is ConnectWise Manage, Huntress, and 1Password.
Datto RMM: $600/mo — the Datto/Kaseya-ecosystem RMM
Kaseya-owned endpoint monitoring, patching, and remote access, commonly bundled with Autotask and Datto SIRIS. The $600/mo list price reflects Kaseya's bundle economics, not a la carte RMM value — which is exactly the failure mode here: buying it standalone, without Autotask PSA or Datto SIRIS in the rest of the stack, means paying bundle pricing for a-la-carte usage and getting none of the reconciliation it's actually priced for.
Feature comparison
| Feature | NinjaOne | Datto RMM |
|---|---|---|
| Endpoint monitoring & patching | ||
| Remote access | ||
| Native PSA tie | ConnectWise Manage | Autotask PSA |
| Native BCDR tie | — | Datto SIRIS |
| Native EDR tie | Huntress | — |
| Native password-manager tie | 1Password | — |
The $525/mo gap between these two is entirely ecosystem, not capability. Datto RMM only earns its premium if you're also running Autotask PSA and Datto SIRIS — otherwise you're paying an 8x markup for the same monitoring and patching job NinjaOne covers for $75/mo.
The actual decision rule
- Already on ConnectWise Manage for PSA: NinjaOne is both the cheaper and the natively-integrated pick — there's no scenario where Datto RMM makes sense here.
- Already on Autotask PSA and Datto SIRIS: Datto RMM's native reconciliation with backup jobs and PSA tickets may justify the premium — but confirm your team is actually using that reconciliation before assuming it's worth $525/mo more.
- Standing up a new MSP from scratch: NinjaOne's price point makes it the default unless you've inherited Datto/Kaseya contracts through an acquisition.
Signs you're paying the Datto RMM premium for no reason
- You're running Datto RMM, but your PSA is ConnectWise Manage, not Autotask
- Your backup platform is Veeam, not Datto SIRIS
- Nobody on the team has used the native Datto RMM-to-Autotask ticket sync in the last quarter
- You inherited Datto RMM through an acquisition and never revisited the choice
- Your EDR (Huntress) and password manager (1Password) both integrate with NinjaOne, not Datto RMM — meaning switching reconnects your security stack too
Under nearly every scenario except a live Autotask + Datto SIRIS deployment, NinjaOne is the fit-for-cost pick. The exception is narrow, and it's worth actually checking, not assuming.
A lot of "best RMM for MSPs" content online is written by, or paid by, whichever vendor has the bigger affiliate budget — which tends to be the pricier platform. Our engine ranks purely on ecosystem and cost fit, structurally blind to which vendor pays the biggest bounty.
