Nexos.ai: Securing AI in Business by 2026

Nexos.ai: A Response to the Challenges of AI in Business

In 2026, the use of artificial intelligence in businesses continues to grow, but this expansion comes with significant challenges. The main risk is no longer that teams will not adopt AI, but rather that they will use it excessively and in a disorganized manner. It is in this context that we tested Nexos.ai, a platform that promises to provide a secure framework for the use of language models (LLMs) in business.

A problem often underestimated is the informal use of AI by employees, who turn to tools like ChatGPT or Claude on their personal accounts to handle sensitive data. This data includes contracts, strategic plans, or human resources reports. This phenomenon, known as "Shadow AI," is not driven by malice but by ease of use and a lack of secure alternatives. Nexos.ai aims to address this issue.

Developed by Nord Security, the company behind NordVPN, Nexos.ai does not seek to create a new AI model but to serve as a centralized platform. It allows teams to access AI available on the market, such as OpenAI, Anthropic, Google, and Mistral, in a controlled environment with strict rules, activity logs, and continuous supervision.

An Intuitive User Interface

At first glance, Nexos.ai stands out from traditional B2B tools with its clear and intuitive user interface. Choosing the AI model is easy via a dropdown menu, allowing even marketing employees to navigate without prior training. The homepage is designed to be straightforward, avoiding the complexity often associated with professional solutions.

A notable detail is the presence of a small European flag next to certain models, indicating that data processing is carried out on servers located in Europe. This feature is crucial for companies subject to GDPR regulations. Additionally, a customization page allows users to define a global profile, including the desired tone and format of responses, while disabling data retention to enhance security.

However, while Nord Security's promise of security is appealing on paper, a thorough assessment of actual security would require a technical audit.

Performance Test: Data Analysis

Processing Internal Documents

To evaluate Nexos.ai, we began with a classic test: analyzing an internal PDF document, specifically a fictional business charter. The AI extracted relevant information without error or hallucination, demonstrating its ability to handle business data without inventing figures. For this task, Nexos used a lightweight and cost-effective embedding model from Mistral, which is an advantage for companies looking to manage their expenses.

In-Depth Research

Next, we tested Nexos's ability to analyze security vulnerabilities of LLMs. Unlike a traditional AI, Nexos conducted real-time research, cross-referencing recent reports to produce a detailed summary with figures and concrete examples. The "Deep Research" mode functions like an analyst, actively searching before providing a response.

Competitive Intelligence

Using the "Competitor Intelligence Scout" template, we requested an analysis of the competition between Databricks and Snowflake. Rather than relying solely on marketing pitches, the tool explored discussions on Reddit to identify users' real concerns.

An Educational Feature: The Model Comparator

Nexos.ai's model comparator is an educational feature that allows users to compare different AI models. We tested Claude Opus 4.7, GPT 5.5, and Gemini 3.1 Pro to extract data from a meeting note and format it in JSON. Claude responded in 713 milliseconds, GPT in 922 milliseconds, while Gemini took over 6 seconds. With equal results, Claude Opus stands out for its speed, which can influence model selection based on the specific needs of the business.

What Will Interest IT Departments

Two aspects of Nexos.ai will particularly catch the attention of IT departments:

• Integration: Nexos integrates natively with Google Workspace and Microsoft 365, and supports the MCP protocol for environments like GitHub or Atlassian.

• Cost Control: The FinOps dashboard provides a detailed view of consumption, user by user and model by model. A key feature is the "Fallback models": in case of server failure from Anthropic or OpenAI, Nexos automatically switches to a predefined backup model, ensuring service continuity.

Competition in the Enterprise AI Market

The Enterprise AI market is saturated, and Nexos faces serious competition. Two notable competitors are:

• Dust: A French solution specializing in connecting knowledge bases and creating no-code document assistants, offered at €29 per month per user.

• Glean: An American player offering impressive indexing capabilities but at a higher cost, estimated at $50 per user per month.

Nexos positions itself at €25 per month per user, or €20 with an annual subscription, offering a broader application scope than Dust while remaining competitive. The distinction is clear: Dust focuses on data governance, Glean on enterprise search, while Nexos positions itself as a governance hub for access to LLMs.
