How to use this comparison

This comparison template is designed for shortlist evaluation with a practical, operator-focused lens rather than vendor-led positioning.

PRTG and Datadog Infrastructure should be separated by the conditions that matter after rollout, not by whoever tells the smoother story in a demo. Use this page to see which option handles your deployment model, operating constraints, and commercial tradeoffs with less friction.

Compare PRTG and Datadog Infrastructure clearly before the buying motion drifts toward the louder vendor narrative.

Editorial analysis

PRTG vs Datadog Infrastructure is a shortlist-stage decision page meant to help IT buyers move from general research into a clearer vendor choice.

PRTG and Datadog Infrastructure usually stay on the shortlist for different reasons. Use this page to see where one product fits the current environment more cleanly, where the tradeoffs start to matter, and which differences deserve more pressure-testing before the team treats either option as the default choice.

  • Compare PRTG and Datadog Infrastructure against the workflows that actually triggered the evaluation.
  • Look for differences in rollout effort, ongoing admin burden, pricing mechanics, and platform scope.
  • Open the individual product pages if the shortlist is still too close to call after the matrix and verdict.

What should actually decide the shortlist

The better fit depends on deployment preferences, automation needs, and how much operational complexity your team can absorb.

Questions to settle before moving forward

Before booking demos, answer these against your environment. If most resolve cleanly, you are ready to move forward — a smoother sales process is not the same as a better product fit.

1

Which product matches the team’s current operating model without requiring unnecessary process change?

2

Which option offers the cleaner path for rollout, onboarding, and long-term operational ownership?

3

Where do pricing mechanics, integrations, and platform scope create meaningful differences?

4

If neither option is a perfect fit, which tradeoff is easier to absorb over the next 12 months?

Frequently asked questions about PRTG vs Datadog Infrastructure

Is PRTG better than Datadog?

+

For on-premises network monitoring, PRTG is better — it offers deeper SNMP, NetFlow, and network device coverage at lower cost. For cloud infrastructure, Kubernetes, and application observability, Datadog is better. The comparison depends entirely on your infrastructure profile. PRTG has higher G2 ratings (4.6 vs 4.3) partly because its simpler use case (network monitoring) is easier to satisfy than Datadog's broader observability scope.

Can Datadog replace PRTG?

+

Datadog can replace PRTG for server monitoring and basic network connectivity checks. However, Datadog's SNMP monitoring is less mature than PRTG's, and it lacks NetFlow/sFlow traffic analysis. For organizations where detailed network device monitoring is critical, PRTG is difficult to fully replace with Datadog. Many organizations run both in parallel — PRTG for network, Datadog for cloud.

How much does Datadog cost vs PRTG?

+

For 200 devices/hosts: PRTG 1,000-sensor license = ~€3,899/yr ($4,300/yr). Datadog Pro for 200 hosts = $3,600/yr (infrastructure only). Base infrastructure costs are comparable, but Datadog's true cost with APM, logs, and other add-ons often reaches $8,000–$15,000/yr for 200 hosts. PRTG's sensor model is more predictable — once you know your sensor count, costs are fixed.

Does PRTG support AWS and Azure monitoring?

+

PRTG includes AWS CloudWatch integration for basic EC2, RDS, and S3 monitoring, and Azure integration for Azure VMs and services. However, coverage is narrower than Datadog's native cloud integrations. PRTG requires more manual configuration per cloud service and does not auto-discover cloud resources the way Datadog does via IAM role integration.

Does Datadog support SNMP monitoring?

+

Yes. Datadog supports SNMP monitoring via the Datadog agent with SNMP integration. It can monitor network devices using standard and device-specific MIBs. However, SNMP monitoring in Datadog is less feature-rich than PRTG — PRTG's SNMP library is more comprehensive, setup is simpler for network admins, and PRTG includes NetFlow analysis that Datadog lacks.

Can PRTG monitor Kubernetes?

+

PRTG has limited Kubernetes support. There are community sensors for basic Kubernetes metrics, but native container and pod monitoring comparable to Datadog's Kubernetes integration requires custom development. For Kubernetes-heavy environments, Datadog, Prometheus/Grafana, or Dynatrace are more appropriate.

Does PRTG have a free version?

+

Yes. PRTG offers a free license for up to 100 sensors, which is enough to monitor approximately 20 devices at the default 5 sensors per device. The free license includes all PRTG features without time limit. Datadog has no free infrastructure monitoring plan — only a 14-day trial.

Is PRTG on-premises only?

+

PRTG is primarily on-premises software installed on a Windows Server. Paessler also offers PRTG Hosted Monitor, a cloud-hosted version of PRTG that eliminates server management. PRTG Hosted Monitor has the same feature set as self-hosted PRTG but is managed by Paessler. Datadog is cloud-only SaaS with no on-premises deployment option.

Which platform is easier to set up?

+

Both are straightforward for their intended use cases. PRTG auto-discovers network devices via network scan and sets up basic sensors automatically — most environments are monitoring within 30 minutes of installation. Datadog agent deployment is also fast, but cloud integration setup (IAM roles, service integrations) can take longer for complex multi-account cloud environments.

Does Datadog include APM?

+

Yes, but APM is a separate add-on product priced at $31/host/mo (Pro) or $40/host/mo (Enterprise). It is not included in Datadog Infrastructure pricing. This is a common source of Datadog cost surprises — organizations budget for infrastructure monitoring but then add APM, logs ($0.10/GB ingested), and synthetic monitoring, significantly increasing total cost. PRTG has no APM capability.
