What Paessler does

Paessler GmbH is a Nuremberg, Germany-based provider of unified IT, OT, and IoT network monitoring software, founded in 1997 and operating as a privately held company under Managing Director Jason Teichman. The company's flagship product, PRTG Network Monitor, is a subscription-based monitoring platform covering network, server, cloud, application, virtualization, and industrial OT environments via 250+ pre-configured sensor types, auto-discovery, distributed remote probes, and vendor-agnostic support for major network and security vendors (Cisco, Fortinet, Juniper, Palo Alto, SonicWall, etc.). The product portfolio includes PRTG Network Monitor (on-premises), PRTG Enterprise Monitor (distributed/offline enterprise), PRTG Hosted Monitor (cloud-hosted SaaS), PRTG UVexplorer (topology mapping added via the 2026 UVnetworks acquisition), and a set of extensions, mobile/desktop apps, and professional services.

Paessler operates a hybrid go-to-market combining product-led growth (30-day free trial, no credit card required), enterprise field sales, and a global MSP and channel partner program, with localization across English, German, Spanish, French, Italian, Portuguese, and other languages. Pricing is subscription-based and tiered strictly by number of devices monitored, ranging from $200/month (50 devices) to $1,642/month (1,000 devices) on annual billing. The company reports a customer base exceeding 100,000 with over 500,000 sysadmin users, spanning SMB and mid-market (primary), distributed enterprise, MSPs, and selected verticals including healthcare, manufacturing/OT, data centers, education, finance, and government. Named enterprise customers include Zurich Airport, Skyscanner, Jena University Hospital, Leica Geosystems, The Ritz London, and FSV Mainz05.

The business is in an active expansion phase following a May 2024 strategic investment from Turn/River Capital (the company's first significant external capital event), three acquisitions between 2023 and 2026 (Qbilon, ITPS Group, UVnetworks), two C-suite hires in April 2026 (CTO Chris Simoes from SolarWinds/Cisco with AI startup background; CPO Mav Turner from Kentik/SolarWinds), entry into the Siemens Industrial Edge Ecosystem for IT/OT convergence, and SOC 2 Type 2 and ISO 27001 certifications completed in March 2026. Revenue is not publicly disclosed; based on customer count, pricing tiers, and PE investment profile, the company is estimated to operate in the $50M-$100M annual revenue band with strong-growth momentum under private equity sponsorship.

• Nagios: Nagios (Nagios XI, Nagios Core, Nagios Log Server) is a long-standing open-source-based network monitoring competitor to PRTG, popular with sysadmins and SMBs and a frequent alternative considered in head-to-head PRTG evaluations.
• Auvik: Auvik is a cloud-based network monitoring and management platform primarily targeting MSPs — directly competing with Paessler's MSP partner program and PRTG multi-tenancy features for managed service providers.
• Progress WhatsUp Gold: WhatsUp Gold is a long-established network monitoring product from Progress Software, offering similar NPM capabilities to PRTG including auto-discovery, flow analysis, and alerting for mid-market and enterprise.

Emerging players

• Checkmk: Checkmk is an open-source and enterprise IT monitoring platform that competes with PRTG in server, application, and network monitoring, particularly in European and cloud-native deployments.

Broad incumbents

• Dynatrace: Dynatrace's unified observability and AIOps platform competes with PRTG at the enterprise level, particularly for organizations pursuing single-platform monitoring across infrastructure, applications, and digital experience.
• Datadog: Datadog is a cloud-native observability leader spanning APM, infrastructure monitoring, logs, and security. It overlaps with PRTG's infrastructure/network monitoring in modern cloud-centric environments but offers a much broader platform.
