The work environment is changing at a rapid pace. With the rise of generative AI in business, the question no longer arises only in terms of software, but also in terms of strategic choice: which AI office suite to adopt to maximize productivity and guarantee data security? In this article, we decipher the essential issues, compare the most advanced solutions on the market and share a concrete practical case to help you make the best choice.

1. Understanding the new generation of office suites

What is an “AI office suite”?

An AI office suite brings together all the tools for creation, editing, collaboration and automation, boosted by artificial intelligence. Unlike traditional suites, an AI office suite offers advanced features:

- Automatic generation of texts or presentations
- Intelligent data analysis (tables, reports)
- Automation of repetitive tasks
- Decision support via contextual insights

Examples: Microsoft 365 Copilot, Google Workspace AI, Delos.

Why is generative AI needed in business?

The productivity gains are spectacular: writing content in a few seconds, accelerated email processing, discovering hidden insights in data... But behind performance, the question of security is increasingly central. Businesses need to not only optimize their processes, but also protect their sensitive information.

2. The essential criteria for choosing an AI office suite

Productivity boosted by AI

- Automation: AI takes care of repetitive tasks so you can focus on what matters most.
- Intelligent assistance: contextual correction, writing suggestions, automatic translation...
- Increased collaboration: automatic reports, document summaries, intelligent management of calendars.

Data security above all

- Encrypted storage and European hosting (compliance with the RGPD)
- Granular access and rights management
- Audit and traceability of user actions
- Protection against data exfiltration or data leaks via AI

You can find the recommendations from the CNIL as for data security.

Easy to handle

The office suite must adapt to all profiles (non-technical or expert) and offer a smooth user experience, otherwise adoption will be blocked.

Scalability and integrations

- Integration with existing business tools (CRM, ERP, etc.)
- Continuous updates and modular modules according to needs

4. Practical case: the AI office suite at the service of a sales department 🏢

background

A French SME with 120 employees wants to modernise its commercial management. Teams spend a considerable amount of time:

• Generate commercial proposals
• Follow up on customer reminders
• Write appointment reports

The CIO hesitates between migrating to an American tech giant or adopting a local solution that is more focused on security and ergonomics.

Deployment with an AI office suite

1. Initial diagnosis

After an audit, several optimization points are identified:

1. Customer data is scattered across multiple tools
2. Manual reporting on Excel takes more than 1 hour per week and per employee
3. No automation of reminders or automatic summary of exchanges

2. Setting up the AI office suite

The choice fell on Delos, the French AI office suite, for its security advantages (local storage, RGPD certification) and its adaptability.

3. Concrete results

• Automatic redaction commercial proposals with generative AI, personalized according to the sector and the customer's history
• Automatic synthesis exchanges and prioritization of reminders in a shared dashboard (Productivity & Security)
• Generating reports meetings in one click, with direct export to the CRM tool‍
• Securing data : all confidential information remains hosted in France, complying with regulatory and business requirements

Result : in 2 months, the sales department divided by 3 the time spent on administrative tasks.

The teams are refocusing on customer relationships with high added value, with the guarantee that the company's strategic data never leaves French territory.

4. Generative AI: an essential ally of productivity (but beware of vigilance)

Generative AI is changing the daily lives of businesses, but it is vital not to sacrifice safety at the altar of productivity.

Best practices for successful adoption:

1. Forming teams : understanding the limits of AI, preventing “hallucination risk”
2. Create governance policies strict data
3. Favour partners who guarantee the traceability and reversibility of data

As such, the example of the Delos platform illustrates the balance between innovation and rigor, by offering a 100% French AI office suite that places productivity AND security at the heart of its applications.

5. Summary: how to choose your AI office suite?

1. List your real business needs (automation, writing, collaboration...)
2. Evaluate the criticality of your data privacy
3. Compare offers based on their AI capabilities, their security guarantees and the ease of integration into your IS
4. Prefer a suite that grows with you, on an open and evolving model

To remember : The AI office suite is no longer a luxury, but a determining criterion of competitiveness for the modern business. It must reconcile the power of algorithms, HR productivity and the protection of digital assets.

Are you looking for a European, efficient and secure solution to accelerate your digital transformation? The Delos platform is now a trusted alternative to combine productivity, ergonomics and security in the same environment — without compromise.
