The best managed service provider software is usually a stack, not one product: an RMM tool to monitor and patch endpoints, a PSA tool for tickets, contracts and billing, plus documentation, backup and security tools. Widely used options include NinjaOne, ConnectWise, N-able, Kaseya, Datto and Atera. The right pick depends on client count, device mix and integrations.
Key takeaways
- RMM (remote monitoring and management) and PSA (professional services automation) are the core; everything else plugs into them.
- Choose between an all-in-one platform (simpler, one contract) and best-of-breed tools (deeper features, more integration work).
- Pricing is usually per device/endpoint or per technician; model both against your 12-24 month growth plan.
- Your RMM has admin access to every client. Treat its security (MFA, segregation, logging) as the top selection criterion.
- Run a 30-day trial on real client devices and measure patch success, alert noise and ticket handling time before you sign.
What software do managed service providers use?
Most MSPs run five to seven tool categories. The table shows what each does and typical examples.
| Category | What it does | Examples |
|---|---|---|
| RMM | Agent-based monitoring, patching, scripting and remote control of client endpoints and servers | NinjaOne, ConnectWise RMM, N-able N-central / N-sight, Kaseya VSA, Datto RMM, Atera, SuperOps, Syncro |
| PSA | Ticketing, SLAs, time tracking, contracts, quoting and billing | ConnectWise PSA, Autotask (Kaseya), HaloPSA, Atera, Syncro, SuperOps |
| Documentation | Client passwords, configurations, network diagrams, runbooks | IT Glue, Hudu |
| Backup and recovery | Server, endpoint and SaaS (Microsoft 365, Google Workspace) backup with restore testing | Datto, N-able Cove, Veeam, Acronis |
| Security | EDR/MDR, email security, DNS filtering, vulnerability scanning | Microsoft Defender, SentinelOne, CrowdStrike, Huntress |
| Network and cloud monitoring | SNMP, firewalls, switches, cloud resources, uptime checks | Auvik, PRTG, Datadog, native cloud tools such as Amazon CloudWatch |
| Remote access | Attended and unattended remote sessions | ScreenConnect, TeamViewer, Splashtop (often bundled in RMM) |
RMM vs PSA: what is the difference?
RMM looks after the machines; PSA looks after the business. RMM agents report health, install patches and run scripts. PSA turns alerts and emails into tickets, tracks time against contracts and produces invoices. Tight integration between the two is what removes manual work.
Best MSP software platforms compared
The platforms below are widely used by MSPs. They are listed alphabetically, not ranked, and descriptions are based on each vendor's own product information. Features and pricing change often, so confirm details in a demo.
| Platform | Type | Known for | Consider if you |
|---|---|---|---|
| Atera | RMM + PSA in one | All-in-one platform with technician-based pricing | Are a small or growing MSP with many devices per technician |
| ConnectWise (RMM, PSA, ScreenConnect) | Suite | Long-established PSA, large integration ecosystem | Want one vendor for PSA, RMM and remote access at scale |
| Datto RMM (Kaseya) | RMM | Cloud-native RMM, close ties to Datto backup | Already use Datto backup or Autotask PSA |
| Kaseya VSA | RMM within the Kaseya IT Complete suite | Policy-based automation and scripting | Want a broad suite with PSA (Autotask), documentation and security from one vendor |
| N-able (N-central, N-sight) | RMM | N-central for larger, complex estates; N-sight for simpler setups; tie-ins to N-able backup and security | Manage large server estates or need on-premises deployment options |
| NinjaOne | RMM with patching, backup and remote access | Fast onboarding and an easy interface | Want quick time to value and a clean UI |
| SuperOps | RMM + PSA | Newer unified platform with built-in automation | Are starting fresh without legacy tooling |
| Syncro | RMM + PSA | Combined platform aimed at smaller MSPs | Want one simple tool and one bill |
Third-party ratings on sites like Capterra and G2 can help, but scores shift month to month and depend on reviewer mix. Read recent reviews from MSPs of your size rather than comparing averages.
How to choose MSP software
Choose on your service model, not feature lists. Start with what you sell (fully managed, co-managed, project work), how many endpoints you manage per technician, and which operating systems and cloud platforms your clients run.
Selection checklist
- Coverage: Windows, macOS, Linux, mobile devices, network gear and cloud resources your clients use.
- Patching: OS and third-party applications, approval rings, rollback, and reporting you can show clients.
- Automation: script library, policy-based actions, self-healing for common alerts.
- Multi-tenancy: strict separation of client data, per-client roles and dashboards.
- Integrations: RMM to PSA, documentation, backup, security, Microsoft 365 and accounting.
- Reporting: SLA, patch compliance and asset reports you can brand and send automatically.
- Security of the tool itself: enforced MFA, SSO, granular permissions, audit logs, EU data hosting if needed.
- Support and onboarding: migration help, documentation quality, support hours in your time zone.
All-in-one platform or best of breed?
| All-in-one (RMM + PSA in one product) | Best of breed (separate specialised tools) | |
|---|---|---|
| Set-up | Faster, one data model | Longer, integrations to build and maintain |
| Depth | Good enough for most small and mid-sized MSPs | Deeper features per category |
| Cost | One contract, often simpler pricing | Several contracts; can cost more in total |
| Lock-in | Higher; switching means replacing everything | Lower; swap one tool at a time |
| Best for | Smaller and growing MSPs | Larger MSPs with specialised teams |
Pricing models
- Per device or endpoint: scales with what you manage. Easy to pass through to clients, but costs rise with every new laptop.
- Per technician: predictable as device counts grow; less attractive for large teams managing few devices each.
- Tiered or custom quotes: common above a few thousand endpoints, often with minimum commitments.
Model your bill for today and for 12-24 months ahead, including add-ons for backup, EDR and remote access that are often priced separately.
Why the security of MSP software matters most
An RMM tool can run code on every client device, so attackers target it. In July 2021, attackers abused Kaseya VSA to deploy ransomware through MSPs to their customers; CISA and the FBI issued guidance for affected MSPs and their customers.
In 2022, the cybersecurity authorities of the UK, Australia, Canada, New Zealand and the US published a joint advisory, Protecting Against Cyber Threats to Managed Service Providers and their Customers. Its recommendations translate directly into tool requirements:
- Enforce multifactor authentication on remote access and admin tools.
- Segregate customer data and services from each other and from internal networks.
- Do not reuse admin credentials across customers.
- Store the most important logs for at least six months, as incidents can take months to detect.
- State security roles and responsibilities clearly in MSP-customer contracts.
For EU MSPs, the NIS2 directive lists managed service providers and managed security service providers as entities in scope, which raises the bar for logging, incident reporting and supply-chain security.
How to run a trial that tells you something
- Pick two or three platforms and one representative client (or your own internal estate).
- Deploy agents to 50-100 real devices across operating systems.
- Run a full patch cycle and record success rate and failed updates.
- Connect alerts to the PSA and measure noise: how many alerts per real issue.
- Build three common automations (disk clean-up, service restart, onboarding script).
- Produce a client-ready monthly report and check it with an account manager.
- Score each tool against your checklist and total cost at your 24-month size.
What this means if you buy managed services
If you are a business choosing an MSP rather than an MSP choosing software, ask which RMM and PSA the provider uses, how access to your environment is secured (MFA, named accounts, logging), and how quickly they respond. Clear answers here say more about service quality than any brochure. The UK NCSC's supply chain security guidance sets out 12 principles for keeping control and oversight of suppliers like your MSP.

Frequently asked questions
What is the best software for managed service providers?
There is no single best tool. NinjaOne, ConnectWise, N-able, Kaseya, Datto, Atera, SuperOps and Syncro are all widely used. Smaller MSPs often prefer an all-in-one RMM and PSA; larger ones combine specialised tools. Trial two or three on real devices before choosing.
What is RMM software?
RMM (remote monitoring and management) software uses an agent on each device to report health, apply patches, run scripts and provide remote access, so an MSP can manage many clients from one console.
What is PSA software for MSPs?
PSA (professional services automation) software runs the business side: ticketing, SLA tracking, time entry, contracts, quotes and billing. It is usually integrated with the RMM so alerts become tickets automatically.
How much does MSP software cost?
Pricing is usually per managed device or per technician per month, with add-ons for backup, security and remote access. Prices vary widely by vendor and volume, so request quotes based on your current and projected endpoint count.
Is free RMM software good enough?
Free tiers can work for a handful of devices or for testing. For paying clients you will need reliable patching, audit logs, MFA, support and integrations, which usually require a paid plan.
