What 株式会社エスイーシー does
株式会社エスイーシー (SEC Corporation) is a privately-held Japanese regional internet service provider founded in 1995 and headquartered in the Hakodate Building in Hakodate, Hokkaido. Operating under the はこだてHotWeb (HotWeb) brand, the company delivers internet connectivity, web hosting, domain email, and cloud-based groupware services to small and medium businesses and individual residents concentrated in the Hakodate region of Hokkaido. SEC is part of the NEC-NET Group, which provides access to enterprise-grade infrastructure and technology resources, and maintains upstream partnerships with KDDI for email infrastructure and NTT East for Flets connectivity.
The company's product portfolio is built around four core subscription offerings: monthly internet access subscriptions for both individual and business customers, the ホスティングサービス (Hosting Service) web hosting and domain registration platform at ¥4,400/month, HotWeb CloudMail (a web-based email service with enhanced security settings priced at ¥165/account/month), and イカす☆Office, a cloud-based groupware system providing scheduling, document sharing, and collaborative workflow tools for business customers. Pricing and product structure was last materially updated in August 2021 following a mail server migration that also renamed the legacy business pack plan to the current hosting service plan.
SEC's business model is almost entirely subscription-recurring, monetized through monthly fees on low-ARPU accounts distributed across a long tail of Hakodate-area customers. Go-to-market is direct: a self-serve website (hotweb.or.jp) serves individuals and SMBs, while enterprise accounts are sold through the Hakodate headquarters office. Marketing relies on local presence, community event participation (including the annual SEC Solution Fair and Hakodate Culture Night exhibitions), and content marketing through the company website. The firm employs approximately 21 people and operates without disclosed parent company, private equity, or venture capital backing.

株式会社エスイーシー competitors and assessment
Company assessmentDirect peers

- @nifty: Established Japanese ISP providing internet access, web hosting, domain, and email services to consumer and SMB segments. Directly competes with HotWeb across the same core product categories and price points.
- Biglobe: Japan-based consumer and SMB ISP offering internet connectivity, web hosting, email, and security services. Directly comparable to HotWeb in product mix (ISP + hosting + email) and target market, though operating at substantially larger national scale.
- Sakura Internet: Japanese hosting and cloud provider offering web hosting, email, VPS, and managed cloud services to SMBs and developers. Directly comparable to SEC's hosting and CloudMail offerings, with stronger technical cloud positioning.
- So-net (Sony Network Communications): Japanese ISP owned by Sony providing fiber, mobile, hosting, and email services to consumers and SMBs. Closely comparable to SEC in offering a bundled connectivity-plus-hosting portfolio, with similar subscription pricing models.
- Asahi Net: Japanese ISP offering fiber, mobile, and hosting services primarily to consumers and small businesses. Comparable to SEC in service mix and subscription pricing structure, though with a stronger national footprint.
Broad incumbents

- KDDI: Major Japanese telecom carrier providing mobile, fixed-line, and ISP services, including the upstream email infrastructure for HotWeb CloudMail. KDDI competes broadly in connectivity and bundled IT services and was the source of a recent breach that affected SEC's email customers.
