Google WorkspaceとMicrosoft 365の比較の要諦

Published: 01 November 2022


Gartnerがアプリケーション・リーダーと共にGoogle WorkspaceとMicrosoft 365を比較する際、初期段階では、「コスト」「セキュリティとガバナンス」「目的適合性」の3要素を調査することが多い。1つ目のコストは、ほかの2要素に大いに左右される。

Included in Full Research


  • Google Workspace (旧G Suite) とMicrosoft 365の価格は、割引を考慮してもほぼ同じである。

  • セキュリティ・サービス面では、Google WorkspaceがMicrosoft 365とほぼ同等レベルを提供できるようになってきた。ただし、いずれも情報ガバナンスの成熟度が十分ではないと考えられるため、規制に関するニーズを完全に満たすには、サードパーティのアドオンが必要になる。

  • Google WorkspaceとMicrosoft 365のいずれも、生産性向上とコラボレーションの標準的な要件に関しては十分に満たしているただし、プロジェクト管理、人事、法務、財務などの特定のユースケースに関して、両者の特徴は異なる。



  • 従業員のコラボレーション要件とさまざまな「新しいワーク・ハブ」スイートの機能 (参照) を比較して、各スイートのコストに対するメリットとデメリットを判断する。ギャップを埋めるために必要となるアドオン・サービス、およびコスト総額を明らかにする。

  • GartnerのSaaSセキュリティ・フレームワークを使用して、法務チームおよびセキュリティ・チームと共に、必要なセキュリティ・サービスとガバナンス・サービスを決定する。

  • 自社のユースケースを考慮して、スイートのアプリケーションが従業員のニーズに適しているかどうかを判断する。
