Who should choose each
Choose Pulszo — you run ISP, MSP or enterprise WAN networks and want automated SLA computation, vendor accountability and fast cloud deployment without managing on-premise servers.
Choose Nagios XI — you have a diverse IT infrastructure that benefits from the massive Nagios plugin ecosystem and you require strict on-premise control over the monitoring environment.
Feature-by-feature comparison
How Pulszo and Nagios XI compare across core network operations capabilities — with context, not just checkmarks.
| Feature | Pulszo | Nagios XI |
|---|---|---|
| SLA Monitoring | Native SLA dashboards with automated computation, breach forecasting and per-vendor uptime tracking. | Availability reports and SLA reporting available natively; automated carrier-level breach forecasting is not a primary focus. |
| Vendor Management | Built-in vendor management module with scorecards ranking carriers by availability, MTTR and recurrence. | No dedicated network-vendor or carrier-accountability module natively. |
| ISP Monitoring | Purpose-built for ISP and enterprise WAN link monitoring at scale. | General IT infrastructure monitoring; ISP/WAN link and carrier-level SLA workflows require custom configuration. |
| SNMP Monitoring | High-scale SNMP discovery, smart polling, traps and configurable thresholds. | Extensive SNMP support with wizards for switches, routers and traps. |
| Link / WAN Monitoring | Real-time link health, latency and packet-loss tracking per link and per vendor. | Bandwidth and port monitoring supported; carrier-level link SLA tracking requires configuration. |
| MSP Support | Native multi-tenant workspaces with data isolation, delegated access and branding. | Multi-tenancy capabilities available, but deep MSP account isolation may require custom setups or multiple instances. Information may vary depending on plan. |
| Incident Management | RCA workflows with correlated evidence and AI-assisted summaries. | Advanced alerting, event handlers and incident management; no AI-assisted root cause analysis natively. |
| Automation | AI recommendations and automated analysis surface likely causes and next actions. | Configuration wizards and automated discovery; event handlers for automated remediation. |
| Alerting | Multi-channel threshold and anomaly alerting with correlation to reduce noise. | Highly customizable alerting, escalations, and scheduled downtime. |
| Reporting | Executive-ready, scheduled reports with operational drill-downs. | Advanced reporting, including SLA, availability, capacity planning and custom reports. |
| Dashboards | Role-based operational dashboards for NOC, engineering and leadership. | Customizable dashboards with per-user views and NOC screen options. |
| API | REST API with scoped keys for automation and integration. | Comprehensive REST API for automation and integration. |
| Integrations | Webhooks plus ITSM and collaboration integrations. | Massive plugin ecosystem (Nagios Exchange) and extensive third-party integration options. |
| Cloud | Cloud-native SaaS that deploys in hours. | Primarily deployed on-premise or on customer-managed cloud VMs. No official SaaS offering. |
| On-prem | Private and hybrid deployment available on enterprise plans. | Yes — self-hosted on-premise Linux is the standard deployment model. |
| Scalability | Unlimited scale options on enterprise plans, with no hardware to add. | Scales well but requires customer-managed infrastructure scaling and distributed execution (e.g., Mod-Gearman). |
| Ease of Use | Modern, operator-first interface focused on signal over noise. | UI is much improved over Nagios Core via configuration wizards, but managing complex environments still requires expertise. |
| Support | Email, priority and dedicated success depending on plan. | Professional commercial support included with licensing. |

Why teams switch from Nagios XI to Pulszo
The recurring themes we hear from network and service-delivery leaders.
No infrastructure to maintain
Pulszo is cloud-first — no Linux servers, databases or distributed executors to provision and maintain.
Faster deployment
Connect your first devices and links within hours instead of navigating complex configuration wizards and plugins.
AI-powered RCA
AI Network Analyst correlates incidents and vendor performance automatically — reducing the need for custom event handlers.
Vendor accountability built in
Vendor scorecards and accountability scoring are native features, not custom reports or spreadsheets.
Automated SLA intelligence
Automated SLA computation with breach forecasting out of the box, rather than basic availability reporting.
Native multi-tenancy
Designed for MSPs with true tenant isolation and branding, rather than relying on role-based views.
