NinjaOne vs Kaseya: Which RMM Platform Fits Your MSP in 2026?

Key Takeaways

• NinjaOne is a cloud-native RMM known for ease of use, with a native PSA added in 2026. Kaseya sells VSA 10 inside a broad suite, most often bundled as Kaseya 365 Endpoint with RMM, EDR, antivirus and backup.
• Both price per endpoint. NinjaOne publishes a range of $3.75 down to $1.50 per device per month; Kaseya publishes no prices, and Kaseya 365 Endpoint requires at least 50 endpoints.
• NinjaOne leads on usability and review volume: 4.7 across 5,401 G2 reviews, against 4.0 across 327 for Kaseya VSA (October 2026).
• Kaseya wins when you want one vendor for RMM, PSA (Autotask), documentation (IT Glue), EDR and backup under a single subscription.
• If you want RMM and PSA without per-device pricing, Syncro is a third option: per technician, unlimited endpoints, from $129 per technician per month billed annually.

MSPs comparing NinjaOne and Kaseya are usually making a bigger decision than which RMM agent to install. NinjaOne is a focused platform that has been adding PSA, documentation and backup around its RMM. Kaseya is a suite, where the RMM is one part of a stack that can include Autotask, IT Glue, Datto backup and Datto EDR.

NinjaOne vs Kaseya at a Glance

What Are NinjaOne and Kaseya?

NinjaOne

NinjaOne positions itself as “RMM for unified IT operations.” Its RMM covers automated OS patching for Windows, macOS and Linux, automatic updates for 200+ third-party applications, condition-based scripting, auto-remediation and four remote access options, all on cloud infrastructure. Backup and mobile device management are sold as separate NinjaOne products.

In 2026 NinjaOne introduced NinjaOne PSA, which combines billing (contracts, time tracking and invoicing), ticketing, documentation and IT asset management, and which NinjaOne describes as “fully native to NinjaOne RMM.” It integrates natively with QuickBooks Online.

Kaseya

Kaseya is a broad IT management and security vendor. Its VSA RMM covers monitoring, automated OS and third-party patching, policy-based automation, remote control and mobile device management. Kaseya also owns Datto, Autotask and IT Glue, so many MSPs buy it as a suite rather than a single RMM.

The flagship bundle is Kaseya 365 Endpoint: RMM (Datto RMM, VSA 10, or VSA 9 for existing users), Datto AV, third-party patching, Datto EDR with ransomware detection, endpoint backup with 5TB of shared storage, and on the Pro tier, RocketCyber MDR. The Express tier drops MDR.

RMM Compared

On paper the RMM feature sets are close. The difference users report is in day-to-day use: NinjaOne is consistently rated easier to deploy and learn, while VSA trades some usability for automation depth and tight links into the rest of the Kaseya suite.

PSA: NinjaOne PSA vs Autotask

This is where the two have converged most recently. NinjaOne has had native ticketing since 2022, but until 2026 it had no billing, so MSPs that needed billing paired it with a third-party PSA. NinjaOne PSA now covers ticketing, contracts, time capture, automated invoicing through QuickBooks Online, documentation and asset management on the same platform as the RMM. QuickBooks Desktop is not supported.

Kaseya’s PSA is Autotask, a mature, separate product with its own subscription that integrates with VSA, Datto RMM and IT Glue. Autotask has a far longer track record; NinjaOne PSA has the advantage of sharing one data model with the RMM.

For MSPs whose billing is complex (multiple contract types, procurement, project billing), Autotask’s maturity matters. For MSPs that want ticketing and invoicing tied directly to endpoint data with less setup, NinjaOne PSA is the simpler path, as long as you are comfortable being an early adopter.

Security and Backup

Kaseya bundles security far more deeply. Kaseya 365 Endpoint includes antivirus, EDR with ransomware detection, endpoint backup and (on Pro) managed detection and response in a single subscription. If your goal is to buy RMM, security and backup from one vendor, Kaseya is built for that.

NinjaOne sells backup as a separate product and relies on integrations for EDR and MDR. That gives you more freedom to choose your security vendor, and more contracts to manage.

Pricing and Contracts

NinjaOne pricing

NinjaOne prices per device, not per technician. Its pricing page states it “starts as low as $1.50 USD per month at 10,000 endpoints, increasing to $3.75 USD at 50 or fewer endpoints,” varying by region and products. Rates in between are tiered and quoted. Vendr reports a median NinjaOne contract of about $8,836 per year across 58 purchases (estimate, February 2026). NinjaOne PSA pricing is not published.

Kaseya pricing

Kaseya publishes no prices for VSA or Kaseya 365. New Kaseya 365 Endpoint customers must start with at least 50 endpoints, and customers upgrading from existing Kaseya products must license as many endpoints as their largest existing component. Kaseya’s billing change, announced December 2025, moved Datto RMM, Autotask and SaaS Protection from high-watermark billing to a committed minimum quantity: you commit to a monthly minimum, pay the per-unit rate above it, and usage peaks no longer raise the minimum. Kaseya says other products will follow.

What this means for your bill

Both vendors bill by device, so both bills grow with your clients’ device counts. NinjaOne lets you see the range before a sales call. Kaseya can be cheaper per endpoint when you take the full bundle, but you will not know until you get a quote, and the committed minimum shapes how far you can scale down.

Security Track Record

Any Kaseya evaluation raises the July 2021 incident. On 2 July 2021, the REvil ransomware group exploited an authentication bypass vulnerability in VSA, hitting about 60 MSPs and, by Kaseya’s estimate, 800 to 1,500 downstream businesses. Kaseya shut down its VSA cloud and SaaS servers, issued advisories, and on 23 July released a universal decryptor (summary).

That was five years ago, on a previous VSA generation, and Kaseya has since released VSA 10. It is still worth asking any RMM vendor, NinjaOne included, how it handles vulnerability disclosure, patch timelines and agent security, since an RMM has privileged access to every client you manage.

Where NinjaOne Wins

• Usability and onboarding. NinjaOne’s 4.7 rating across 5,401 G2 reviews is the strongest signal in this comparison. MSPs that need technicians productive quickly, or that are leaving a platform they found hard to use, tend to prefer it.
• Pricing visibility. NinjaOne publishes its per-device range and offers a 14-day trial, so you can budget and test before talking to sales.
• Flexibility on security vendors. Because NinjaOne does not bundle EDR, you can keep the security stack you already trust.

Where Kaseya Wins

• One vendor for the whole stack. Kaseya 365 Endpoint puts RMM, AV, EDR, ransomware detection, backup and (on Pro) MDR in one subscription, and Autotask and IT Glue are part of the same ecosystem. MSPs consolidating vendors get further with Kaseya than with NinjaOne.
• PSA maturity. Autotask has years of complex-billing use behind it. MSPs with procurement, project billing and multi-contract clients may find NinjaOne PSA too new.

A Third Option: Syncro

NinjaOne and Kaseya share one thing: both charge per device, so every laptop a client adds raises your bill. Syncro takes a different approach. It is an all-in-one RMM and PSA platform for MSPs, priced per technician with unlimited endpoints: Core is $129 per technician per month billed annually ($159 monthly) and Team is $179 ($209 monthly), which adds Microsoft 365 management, CIS-aligned security baselines and AI ticket triage. See Syncro pricing.

Syncro does not bundle its own EDR or endpoint backup; security tools like Guardz, Bitdefender and Acronis connect through the Syncro Marketplace. For a direct comparison with NinjaOne, see Syncro vs NinjaOne. For the wider field, see our guides to NinjaOne competitors and Kaseya competitors.

Which Should You Choose?

• Choose NinjaOne if ease of use and fast onboarding matter most, you want to see pricing before a sales call, and you prefer to pick your own security vendors.
• Choose Kaseya if you want RMM, PSA, documentation, EDR and backup from one vendor, your billing needs Autotask’s depth, and you are comfortable with quote-based pricing and a committed minimum.
• Consider Syncro if per-device pricing is the problem, and you want RMM and PSA in one platform with a flat per-technician bill and unlimited endpoints.

Conclusion

NinjaOne and Kaseya solve different problems. NinjaOne is the easier platform to run day to day, with transparent per-device pricing and a native PSA that is still proving itself. Kaseya is the broader bundle, trading pricing visibility and simplicity for one vendor across RMM, PSA, security and backup.

The right choice comes down to what you are optimizing for: usability, consolidation, or a bill that does not grow with every client device. Decide which of those matters most to your MSP, and the shortlist usually becomes one name.
