What Ever Electronics does

Ever Electronics Co. Ltd. (エバ電子株式会社) is a private Japanese software and niche technology distributor headquartered in Saitama, Japan, with a headcount of 11–50 employees. The company develops and sells environment restoration software — most notably the HDD KEEPER 9 series (Business Edition, Business Edition type-S, Light, and Light type-S) — which automatically resets Windows PCs to a configured state upon restart, erasing user input, saved files, and operation history. The product supports Windows 11 including the 25H2 release (as of November 2025) and is positioned as a security and maintenance solution for shared, public-access, and managed PC environments. Core technology is system-level software integration with the Windows OS, providing malware/ransomware resistance, information leakage prevention, and dramatically reduced primary maintenance burden for institutional IT administrators.

Beyond HDD KEEPER, Ever Electronics has built a complementary education technology product suite targeting the Japanese K–12 and higher education market: School CAP3 (classroom instruction management software), Attendance BOOK (cloud-based attendance tracking supporting QR codes, Bluetooth beacons, Felica, and web browser registration), Hapara Highlights (browser-based classroom management integrated with Google Classroom and Google Workspace for Education, aligned with the Next GIGA School initiative), Digital P15 (HDMI/DVI one-way image distribution for classrooms), and SYMFLOW (bidirectional presentation support for lectures and events). The company also serves as the authorized Japanese reseller of OPHIT Co., Ltd.'s digital interface products, including 8K-compatible DisplayPort and HDMI optical fiber extenders.

Ever Electronics generates revenue primarily through one-time perpetual software licenses (HDD KEEPER), recurring subscriptions (Attendance BOOK, Hapara Highlights), and hardware resale of OPHIT products. Pricing across most lines is quotation-based rather than publicly disclosed. The company sells direct to institutional and enterprise customers — education institutions, government offices, hospitals, hotels, internet cafes, KIOSK/POS operators, and corporate shared-PC environments — primarily through its website, downloadable PDF catalogs, phone, and email inquiry channels. Geographic focus is the Japanese domestic market, with no evidence of international expansion.

Direct peers

• LanSchool (Lenovo): LanSchool is a teacher-driven classroom management product (now part of Lenovo) that overlaps with School CAP3 and Hapara Highlights, addressing the same screen-monitoring, screen-locking, and instructional-control workflows in schools.
• Hapara (Hapara Highlights): Hapara is the original developer of Hapara Highlights, the same browser-based classroom management tool Ever Electronics distributes in Japan. While they have a reseller relationship, they are also direct peers in the same classroom-management product category competing for the same Google Classroom-integrated deployments.
• Horizon DataSys (Reboot Restore Rx): Horizon DataSys' Reboot Restore Rx is a closely analogous Windows environment-restore product that automatically reverts PC changes on reboot. It competes head-to-head with HDD KEEPER for shared workstation, classroom, and kiosk use cases.
• Centurion Guard Technologies (SmartShield): SmartShield provides Windows system lockdown and restoration software closely comparable to HDD KEEPER, addressing the same use cases of securing shared/public PCs and preventing persistence of user data.
• Drive Vaccine (Smart-Soft): Drive Vaccine offers Windows rollback/restore software with similar restart-restore semantics to HDD KEEPER, targeting the same education, public-access-PC, and enterprise shared-terminal customer base.
• Netop (Vision Pro / Classroom Management): Netop's classroom management and remote-lab software is comparable to Ever Electronics' School CAP3 — both target teacher-controlled classroom/lab oversight and instruction support in K-12 and higher education.
• Faronics (Deep Freeze): Faronics' Deep Freeze is the global market-leading counterpart to Ever Electronics' HDD KEEPER — both provide restart-based system restoration (reboot/restore) that resets a Windows PC to a frozen baseline state. Deep Freeze is the most directly competitive product to HDD KEEPER worldwide and competes for the same shared-public-PC and education deployments.

Broad incumbents

• Impero Software: Impero offers a broader education IT management platform that includes classroom management, network monitoring, and safeguarding — overlapping with Ever Electronics' School CAP3 and Hapara Highlights, but spanning a wider education-IT footprint.
