What Castor Networks does

Castor Networks is a Netherlands-headquartered satellite internet service provider founded in 2005 as a management buy-out of KPN's satellite broadcasting division. The company delivers LEO and GEO satellite connectivity exclusively to enterprise, government, and NGO customers across mining, energy (oil and gas), humanitarian, and government/defense verticals, with operational presence in the Netherlands, a teleport facility in Burum, and a regional office in North Vancouver, Canada.

The company operates a multi-constellation technology stack combining owned GEO VSAT infrastructure (C-band and Ku-band) with resold LEO services from Starlink (Authorized Reseller) and OneWeb (Service Provider). Core technology assets include the Burum Teleport with 13 antennas ranging from 3.7m to 18m, all N+1 redundant with automatic switch-over, connected by redundant fiber to Amsterdam Global Switch with Amsterdam Internet Exchange peering. The proprietary VOYAGER platform provides iDirect VSAT customers with application-level bandwidth monitoring and blocking, while an in-house Customer Portal delivers real-time visibility into speed, data usage, and signal levels per remote site. SCPC dedicated services run on Newtec MDM6000 modems (50-200 Mbps), and shared broadband runs on iDirect Evolution (up to 60 Mbps down / 18 Mbps up). Field engineers hold BOSIET, HUET, MIST, and H2S offshore certifications.

Castor Networks generates revenue primarily through recurring monthly subscriptions on VSAT and LEO plans, with published Yahclick DRC tiers ranging from $55 to $2,100 per month and unlimited SCPC/CIR plans up to $2,100 per month. Secondary revenue streams include hardware sales (Starlink High Performance antennas, routers, cables), wholesale teleport services and satellite capacity leasing to other service providers, managed multi-site VSAT networks with group bandwidth pooling, and business-grade VoIP telephony with local DID numbers from 55+ countries. The company sells exclusively through direct enterprise field sales, supported by a 24/7 manned NOC, an online ticketing portal, and dedicated regional sales contacts (Netherlands, Canada, DRC), with a sister company Castor Marine handling maritime connectivity.
