Computing in 2026 is no longer just about choosing a good antivirus or updating your operating system. With the rise of artificial intelligence in everyday use, a tightening European regulatory framework, and evolving cyber threats, the technical landscape is changing at a pace that concerns both professionals and informed individuals alike.
Data Exfiltration: The Cyber Threat That Backups Alone Do Not Cover
The classic reflex in the face of cyberattacks is to multiply backups. This approach protects against ransomware, but it does not address the threat that is progressing the most in 2026.
The 2025 Cyber Threat Landscape report published by ANSSI indicates a significant increase in data exfiltration incidents compared to the previous year. The theft of sensitive files, without encryption or ransom demand, is gaining ground, particularly among SMEs. Attackers copy the data and then resell or exploit it, sometimes without the victim realizing it for several weeks.
To guard against this, three areas deserve the attention of any IT manager, even in a small organization:
- Access segmentation, which limits what a compromised account can reach. A salesperson does not need access to accounting files, and vice versa.
- Reducing administrative privileges, including for external service providers who work remotely on the network.
- Monitoring unusual transfers: an abnormal volume of data leaving the network at night or to an unknown destination should trigger an alert.
Among the IT articles from Journal du Webmaster, several reports detail these protective mechanisms suitable for organizations of all sizes.
Artificial Intelligence in Very Small and Small Enterprises: Concrete Uses but Blind Spots
The France Num Barometer 2026, published on October 2, 2026, confirms a clear increase in the adoption of AI in very small and small French businesses. The dominant uses remain content generation and customer interaction assistance.
Writing a product sheet, rephrasing an email, summarizing a long document: these tasks are now delegated to generative AI tools in an increasing number of organizations. However, feedback from the field varies regarding the reliability of the responses produced, especially in technical or regulatory areas.
Three Concrete Precautions Before Generalizing AI
Systematically verifying generated responses remains the first reflex to instill. A text produced by AI can be fluid, well-structured, and factually incorrect. Human proofreading is not a luxury; it is a safety net.
The confidentiality of transmitted data poses a more subtle problem. Copying and pasting a client contract into a public AI assistant amounts to sharing that document with a third party. Defining an internal charter for AI use helps establish what can be submitted to these tools and what must remain internal.
The third point concerns dependency. Automating the drafting of standard emails saves time, but if no one on the team knows how to write without assistance, a cloud service outage becomes an operational blockage.
European Regulation on AI: What Changes in 2026
The European AI Act is no longer a project. Since February 2, 2025, the obligation to master AI applies to organizations deploying or using these systems. This means that companies must ensure their teams have a sufficient level of competence to handle the AI tools they use.
This requirement does not only concern developers or data scientists. It also targets end users, those who interact daily with assistants, automated sorting tools, or recommendation systems.
Transparency on AI-Generated Content
One aspect of the regulation directly affects content creators and companies that publish online. Labeling AI-generated content becomes mandatory, with implications for websites, marketing campaigns, and automated communication materials.
The available data do not yet allow for measuring the actual compliance rate of French companies on this point. The sanctions provided for by the regulation exist, but their effective application remains to be seen in the coming months.
Everyday IT Security: The Actions That Matter Regardless of Level
Underlying trends (AI, regulation, sophisticated threats) should not overshadow the fact that the majority of security incidents exploit basic vulnerabilities. A reused password, a postponed update, a click on a suspicious link.
For users of all levels, a few practices make a real difference:
- Enable two-factor authentication on all accounts that allow it, starting with email and cloud services.
- Keep software up to date, including the web browser and extensions. Security patches fix vulnerabilities that have already been exploited.
- Separate professional and personal uses, even on the same device, by using different profiles or sessions.
- Test your backups: a backup that has never been restored is an unverified promise.
These actions may seem basic. However, they remain absent in a significant portion of organizations affected by incidents, according to feedback published by ANSSI.
Computing in 2026 requires less adopting every new thing than mastering the fundamentals while gradually integrating regulatory and technical evolutions. The competence of users, at all levels, remains the link that determines whether a tool is an asset or a risk.
