Which solution is better for your business, Nextcloud Workspace or Microsoft 365?

In today’s work en­vir­on­ment, efficient digital work­spaces are essential. Both Nextcloud Workspace and Microsoft 365 provide tools for col­lab­or­a­tion, com­mu­nic­a­tion, and document man­age­ment. While the platforms offer a wide range of features, they differ in areas such as hosting, data pro­tec­tion, and flex­ib­il­ity. This article outlines the key dif­fer­ences and helps you determine which solution best fits your company’s needs.

Overview of Nextcloud Workspace vs Microsoft 365

Nextcloud Workspace at a glance

Nextcloud Workspace is an in­teg­rated office suite for companies that value security, flex­ib­il­ity, and data pro­tec­tion. It combines files, office ap­plic­a­tions, com­mu­nic­a­tion tools, and auto­ma­tion features in a central work en­vir­on­ment. All data is hosted on IONOS servers in European data centres, so you retain full control.

Its modular ar­chi­tec­ture allows you to enable exactly the features your company needs. Groupware apps such as Mail, Calendar, Contacts, and Deck support efficient team or­gan­isa­tion. Office tools and the AI Assistant help teams work pro­duct­ively in real time, while Nextcloud Talk enables secure com­mu­nic­a­tion through chat and video con­fer­en­cing. Ad­di­tion­al auto­ma­tions can be set up in­di­vidu­ally using Flow, Tables, and the API.

Microsoft 365 at a glance

Microsoft 365 is a cloud-based platform for pro­ductiv­ity, com­mu­nic­a­tion, and col­lab­or­a­tion that is used worldwide in companies of all sizes. It offers well-known Office ap­plic­a­tions such as Word, Excel, and Power­Point, as well as tools for com­mu­nic­a­tion, project planning, and teamwork. With Outlook, Teams, Share­Point, and OneDrive, companies have com­pre­hens­ive options for email man­age­ment, file storage, and real-time col­lab­or­a­tion.

Microsoft 365 is delivered entirely through the cloud, allowing users to access their data anytime and from any device. Licensing is managed through per-user sub­scrip­tions, and regular updates ensure that all features stay current. The platform is es­pe­cially suited for companies that prefer stand­ard­ised, fully managed solutions and do not want to run their own servers.

Nextcloud Workspace and Microsoft 365 compared

Although both solutions are es­sen­tially col­lab­or­a­tion tools, a direct com­par­is­on between Nextcloud Workspace and Microsoft 365 reveals several key dif­fer­ences.

Hosting and data control

Nextcloud Workspace places a strong emphasis on secure hosting. When hosted by IONOS in protected data centres, all data remains fully under your control, ensuring that sensitive in­form­a­tion is not auto­mat­ic­ally stored in the cloud of an external third-party provider. This approach is es­pe­cially suitable for or­gan­isa­tions with strict com­pli­ance or data sov­er­eignty re­quire­ments. Microsoft 365, by contrast, is entirely cloud-based, and data is stored in Microsoft data centres depending on the sub­scrip­tion region. While security and en­cryp­tion mech­an­isms are in place, or­gan­isa­tions have limited control over the physical location where their data is stored.

Costs

In our com­par­is­on of Nextcloud and Microsoft 365, both solutions use per-user sub­scrip­tion models. Microsoft’s pricing varies by package and includes different feature options, with advanced cap­ab­il­it­ies such as identity and access man­age­ment available only in higher-tier packages. Microsoft’s AI assistant Copilot is also offered as a paid add-on. With Nextcloud Workspace, all customers receive the same core set of features, including the full office suite and AI Assistant, while pricing mainly depends on the number of users.

Apps and modules

Nextcloud Workspace is built on a modular system that can be flexibly adapted to the needs of different or­gan­isa­tions. The platform includes office ap­plic­a­tions for word pro­cessing, spread­sheets, and present­a­tions, as well as groupware services for email, calendars, and contacts. In addition, modules can be extended with extra apps or in­teg­ra­tions. This open ar­chi­tec­ture makes Nextcloud es­pe­cially versatile and highly cus­tom­is­able.

Microsoft 365, by contrast, offers a com­pre­hens­ive set of well-es­tab­lished ap­plic­a­tions used by companies around the world. The programs are tightly in­teg­rated, creating a con­sist­ent user ex­per­i­ence across the platform. However, the structure is largely pre­defined and offers only limited cus­tom­isa­tion options. As a result, Microsoft 365 provides a clear and stand­ard­ised en­vir­on­ment, but with less flex­ib­il­ity for in­di­vidu­al ad­just­ments.

Data pro­tec­tion and com­pli­ance

Nextcloud Workspace is es­pe­cially appealing for companies that must comply with strict data pro­tec­tion re­quire­ments. Because the data is stored on servers in European data centres, or­gan­isa­tions retain full control over access, storage, and pro­cessing. Nextcloud therefore meets strict European data pro­tec­tion standards and is not subject to the CLOUD Act.

If you subscribe to Microsoft 365 directly, you still benefit from various security mech­an­isms and com­pli­ance cer­ti­fic­a­tions. However, data sov­er­eignty remains with the provider. As a U.S. company, Microsoft is also subject to the CLOUD Act. Or­gan­isa­tions using Microsoft 365 therefore rely on con­trac­tu­al agree­ments and com­pli­ance frame­works to address their data pro­tec­tion re­quire­ments.

Flex­ib­il­ity and cus­tom­is­ab­il­ity

Nextcloud Workspace can be adapted very flexibly to business processes through modules, APIs, and auto­ma­tion tools. Companies can create custom workflows and implement their own in­teg­ra­tions. In com­par­is­on, Microsoft 365 follows a more stand­ard­ised approach. Cus­tom­isa­tions are limited to the options provided by Microsoft, which can simplify im­ple­ment­a­tion but offers less freedom for in­di­vidu­al con­fig­ur­a­tion.

Col­lab­or­a­tion and com­mu­nic­a­tion

Nextcloud Workspace supports real-time document editing, chat, video con­fer­en­cing through Talk, and task man­age­ment. The in­teg­ra­tion of these modules helps create smooth and efficient workflows. In com­par­is­on, Microsoft 365 offers similar cap­ab­il­it­ies through Teams, Outlook, Share­Point, and the Office ap­plic­a­tions. Real-time col­lab­or­a­tion is also supported there, though com­mu­nic­a­tion and col­lab­or­a­tion take place within the Microsoft ecosystem.

Support and community

With Nextcloud Workspace, you receive 24/7 support from the IONOS premium customer service team. Microsoft 365 also provides cent­ral­ised support from Microsoft along with extensive doc­u­ment­a­tion and help resources.

Choosing between Nextcloud Workspace and Microsoft 365

Nextcloud Workspace and Microsoft 365 address similar needs but follow fun­da­ment­ally different ap­proaches. With hosting designed for strong data pro­tec­tion and full control over stored in­form­a­tion, Nextcloud is par­tic­u­larly well suited for companies that pri­or­it­ise data security, data ownership, and flex­ib­il­ity. Its auto­ma­tion cap­ab­il­it­ies and high level of cus­tom­is­ab­il­ity make the platform ideal for teams that want to tailor their work en­vir­on­ment to their specific processes.

Microsoft 365, by contrast, stands out with stand­ard­ised, ready-to-use tools that are widely used around the world and tightly in­teg­rated. However, as a U.S. company, Microsoft is subject to the CLOUD Act, which may be less suitable for or­gan­isa­tions that require complete control over their data in­fra­struc­ture.

In practice, this leads to clear use cases. Privacy-focused or­gan­isa­tions, such as those in health­care or public ad­min­is­tra­tion, benefit from Nextcloud Workspace because data can remain on European servers. Small to medium-sized teams with dynamic workflows often use Nextcloud to automate processes and adapt them to their own working methods.

Large, in­ter­na­tion­ally operating companies fre­quently rely on Microsoft 365 because its stand­ard­ised ap­plic­a­tions help enable con­sist­ent col­lab­or­a­tion across different countries and teams.
