What FireStorm ISP GmbH does

FireStorm ISP GmbH is a privately held Swiss hosting company founded in 2002 and headquartered in Tann, Zurich Oberland. It operates a portfolio of internet infrastructure services targeted at Swiss and DACH SMBs, individuals, web design agencies, resellers, and application developers. The company manages over 45,000 domains and tens of thousands of websites, while its Server2SMS SMS gateway product is reported as used by over 200,000 customers globally.

The product stack is anchored on shared web hosting running on SSD storage in Swiss data centers, with a proprietary SiteDesigner website builder (now including AI-powered website generation), domain registration, dedicated root servers (Linux and Windows), server housing, SSL certificates, cloud storage, DDoS protection, GPU servers, and Office 365/Exchange Online reselling. Technically, FireStorm emphasizes renewable-energy-powered infrastructure, automated DNSSEC deployment (where it claims Swiss first-mover status), twice-daily backups with 60-day retention, mandatory two-factor authentication on its administration portal, and proprietary tooling for diagnostic checks (WHOIS, DNS, SPF/DMARC/DKIM/DANE, SSL Converter).

The business model is primarily subscription-recurring: monthly hosting plans starting at CHF 4.95, annual domain registrations, root server and reseller subscriptions, and add-on SSL/mail/cloud services. A secondary usage-based stream comes from the Server2SMS SMS gateway, monetized via a one-time CHF 40 connection fee, pay-as-you-go SMS credit purchases with volume discounts, and an optional CHF 19.90/month two-way subscription. Go-to-market is self-serve, product-led through firestorm.ch, supplemented by phone (0848/0844 numbers plus a German line) and live chat inside sales, and a white-label reseller program. The company is founder-managed by sole Managing Director Christian Geissler, holds no disclosed outside funding, and operates under Swiss Data Protection Act and GDPR compliance frameworks.
