ローンチイベント: スマートAI Security 。 完全なデータ制御。 ウェビナーに登録する
Hankyu Hanshin Properties Corp., a core comprehensive real estate developer within the Hankyu Hanshin Holdings Group, is pursuing its digital transformation vision, “DX Vision,” to shape the future of urban development. As the company accelerates its cloud migration through various digital transformation initiatives, it adopted Netskope to build a Zero Trust foundation that balances both security and user convenience. With enhanced visibility and control over cloud services, the elimination of reliance on VPN, and improved remote‑work performance, the company has strengthened its security posture while modernizing workstyles—thereby accelerating the realization of its “DX Vision.”
For more than a century, the Hankyu Hanshin Holdings Group has contributed to the creation of vibrant communities and attractive railway-line areas. As a core company within the group, Hankyu Hanshin Properties is a comprehensive real estate developer engaged in a wide range of projects, including its “Geo” condominium brand, residential development, office buildings, commercial facilities, and large-scale urban development. In the Osaka Umeda area, which aims to be an international exchange hub, the company is steadily advancing multiple projects such as the Umekita Phase 2 Development and the Shibata 1-chome Project. Leveraging the expertise cultivated through railway-line development, the company is also expanding beyond the Tokyo metropolitan area into overseas markets, particularly in Asia.
Hankyu Hanshin Properties is pursuing its “DX Vision,” a digital transformation initiative designed to leverage digital technologies and continue delivering “services and experiences that customers choose first” for the next 100 years. Kuniharu Seike, Manager of the Core IT Management Group and the DX Planning and Promotion Group within the Corporate Planning Division’s DX Promotion Department, explains:
“The DX Promotion Department works alongside each business unit to drive business DX, operational DX, and value DX. These initiatives extend beyond just our company—they apply to all real estate–related group companies as well. Within that structure, the Core IT Management Group is responsible for our internal information systems.”
From the standpoint of operational DX, the company needed to modernize workstyles by achieving both strong security and high user convenience. The key to enabling this transformation was Netskope, which provides the foundation for implementing Zero Trust.
Our existing remote access solution authenticated through servers at domestic data centers, which caused latency due to traffic backhauling for overseas offices, even within Japan, remote-work connections would sometimes become unstable.
Leveraging cloud services is essential for advancing digital transformation. Reflecting on past challenges, Mitsuru Ishigami of the Corporate Planning Division’s DX Promotion Department, Core IT Management Group, explains that as the company shifted to the cloud, they needed “more flexible controls—not just allowing or blocking access, but managing actions such as viewing, uploading, downloading, and posting,” and that “traditional filtering solutions simply couldn’t meet these requirements.”
From a security perspective, the company primarily uses Box as its standard storage service. However, because real estate projects often involve collaboration with external partners, different storage services are sometimes preferred depending on the project. Ishigami notes that “we couldn’t simply block those services, so as a workaround—while maintaining our security policies—our department would download files on behalf of employees and store them in Box,” although “as the number of requests grew, the operational burden became significant.”
Managing shadow IT and moving away from a VPN with known vulnerabilities also became critical themes for strengthening security. Additionally, their existing remote access environment had performance issues. Assistant Manager Shoichi Matsukawa explains that “our existing remote access solution authenticated through servers at domestic data centers, which caused latency due to traffic backhauling for overseas offices,” and adds that “even within Japan, remote-work connections would sometimes become unstable.”
In 2023, the company began evaluating Zero Trust solutions to enable secure and convenient cloud service usage while resolving remote access challenges. Ishigami recalls that after consulting with Marubeni IT Solutions—a long-time business partner—they were introduced to Netskope and that “visiting a company already using Netskope and hearing their direct experience gave us confidence that Netskope could address our issues.”
When comparing different solutions, Ishigami highlights Netskope’s advantages, stating that “Netskope integrates CASB, SWG, and ZTNA into a unified platform, whereas competing products often required more complex architectures.” He also emphasizes that “Netskope’s granular control of cloud service permissions, its advanced blocking categories, and the ability to manage generative AI services were major strengths,” adding that “these categories are continuously updated, allowing us to keep pace with the latest cloud services.”
Kuniharu Seike further stresses that “for secure and reliable remote work, the ability to use CASB for cloud service visibility together with a VPN‑less environment was a major advantage.”
Netskopeでは、SaaS上でリスクの高い操作を検知すると、ユーザーの画面にポップアップで警告を出すことができます。ユーザーの行動を一律に禁止するのではなく、『なぜ危険なのか』を伝えたうえで、適切な行動へ促せる点がユニークでした
Netskopeの導入は2025年7月より開始。同年9月からの段階的なリリースを経て、10月までに約1000名規模のユーザーへの展開を完了しました。Netskopeの導入によって、Speeeのセキュリティ運用は大きく変わりました。その象徴的なポイントが、ユーザー行動に対する“導き方”です。
従来のセキュリティ対策では、リスクを避けるために機能や操作を全面的に禁止するような運用もありました。「その結果、ネットワークが止まってしまい、業務に支障をきたすケースもありました」と松本氏は話します。
「Netskopeでは、SaaS上でリスクの高い操作を検知すると、ユーザーの画面にポップアップで警告を出すことができます。ユーザーの行動を一律に禁止するのではなく、『なぜ危険なのか』を伝えたうえで、適切な行動へ促せる点がユニークでした」(松本氏)
実際に、導入後には“ヒヤリハット”と呼べる事象も検知されています。ユーザーが私物アカウントで生成AIサービスを利用し、業務データを扱っている可能性が確認されたケースです。松本氏は「重大な情報漏えいにつながりうる事象だったと思いますし、それを事前に検知できたおかげで、ユーザーに直接説明・指導することができました。推奨するAIツールへの誘導も含め、適切な対応ができたのはNetskopeのおかげです」と説明しました。
このようにNetskopeは、ユーザーの自由度を尊重しながらも、越えてはいけない“危険なライン”を明確にし、ガバナンスを効かせるための基盤として機能しています。
SaaS上の操作レベルまで可視化でき、ユーザーに理由を伝えながら制御できる点はNetskopeならではだと感じています。体感速度を落とさずにガバナンスを効かせられるのは大きな価値です。
上述したセキュリティ面の成果に加え、Netskope導入による効果は、まずはネットワークアクセスの改善が挙げられます。NetskopeのSWG機能によって通信経路が最適化された結果、実測値として約30%のレイテンシー(通信速度)の改善が図られています。松本氏は「社内アンケートでも、『つながりやすくなった』『体感速度が向上した』という声が多く寄せられ、ユーザー満足度は明らかに高まりました」と話します。
あわせて、オンプレミスのVPN機器の撤廃も進みました。ファシリティ領域において、年間でのコスト負担の大幅な軽減が見込まれています。VPN機器の運用や保守の負担が軽減されたことで、情シス部門はより付加価値の高い業務に注力できるようになりました。
こうした多くの成果は経営陣からも高く評価されており、プロジェクトをリードしてきた松本氏は、社内表彰(全社MVP)を受賞しました。
今後は、Netskopeを軸にユーザーの自由度・自律性を妨げないゼロトラストネットワークの完成度をさらに高めていく考えです。松本氏は「すでに導入済みのEDR(エンドポイント検知・対応)、EPP(エンドポイント保護)、SIEM(セキュリティ情報イベント管理)などのセキュリティ製品群とNetskopeの連携を強化することで点在するセキュリティ対策を統合し、『面』としての防御力を高めていくことを目指しています」と話します。
さまざまな社内業務にAIエージェントが適用され、自律的にデータをやり取りするようになる時代を見据え、AIの利活用とセキュリティの両立に、今後もNetskopeが貢献していきます。
