The consequences of a cyber attack

According to a survey by CLUSIF (French Information Security Club), the average cost of a cyber attack for a French company is 286,000 euros. When a company is attacked, there can be :

  • An interruption of its activities,  
  • Deterioration of its IT equipment,  
  • A leak of the data necessary for its operations,
  • An attack on its reputation.  

These events can add up to very significant costs for the company concerned.

In addition, the disruption of business following a cyber attack can have a significant impact on a company's annual revenue. The time it takes to repair the computer system and recover lost data (if any) results in an average 27% loss of annual revenue. And, according to one study, 60% of small and medium-sized businesses that suffer an attack fail to recover and go out of business within 18 months.

Microsoft Security Copilot works using a behavioral analysis approach. This means that it evaluates the behavior of users, applications and systems to detect anomalies that could indicate malicious activity.  

The service also uses advanced detection technologies such as threat monitoring, behavioral analysis and machine learning to identify potential threats and combat them effectively.

In addition to real-time monitoring, Microsoft Security Copilot also offers rapid remediation services to help mitigate security issues. Microsoft security analysts work with customers to identify and resolve security issues, and provide recommendations for improving overall system security.

First of all, it provides continuous monitoring of the IT work environment, which allows for the detection of potential threats and their quick remediation. In addition, it uses advanced technologies to identify threats, making its detection more accurate and effective.

Another advantage of Microsoft Security Copilot is that it is managed by Microsoft. This means that customers don't have to worry about managing the security infrastructure. Microsoft security analysts work with customers to identify and resolve security issues, and provide recommendations for improving overall system security.

In addition, Microsoft Security Copilot is easy to use. It does not require advanced technical skills and can be configured quickly. It also offers analytics and reporting capabilities, allowing customers to track detected threats and take action to mitigate them.

Finally, Microsoft Security Copilot is highly scalable. It can be used to protect a small number of devices or a large corporate network. This makes it an ideal choice for businesses of all sizes looking to strengthen their IT security.

In conclusion, Microsoft Security Copilot is an effective managed security service that provides real-time monitoring of IT work environments and helps detect potential threats before they cause damage.

What is generative AI at work?

chevron down icon

Generative AI at work refers to AI models (like Microsoft Copilot, ChatGPT, Claude, Gemini) that produce content — text, images, code, summaries — based on prompts. In the enterprise context, it's used to draft emails, summarize meetings, answer questions from internal data, automate document creation, and assist decision-making.

What are the risks and limits of generative AI in the enterprise?

Main risks: hallucinations (factually wrong outputs), data leakage (sensitive info sent to public LLMs), copyright issues on generated content, over-reliance reducing human expertise, and inconsistent quality across users. Mitigations: use Microsoft 365 Copilot or similar enterprise-grade tools with data residency guarantees, train employees on prompt design, and validate outputs on critical workflows.

Why choose a solution integrated with the Microsoft environment?

Using a Microsoft-integrated solution simplifies your digital experience. It keeps users within familiar tools like Teams and SharePoint, reducing complexity and enhancing productivity with a seamless, unified experience.

What is Microsoft Security Copilot and how does it work?

chevron down icon

Microsoft Security Copilot is an AI assistant for security teams, trained on Microsoft's global threat intelligence and integrated with Defender, Sentinel, Entra, and Intune. It works by allowing security analysts to ask natural language questions—'What happened in this incident?', 'Is this IP address associated with known threats?'—and receive step-by-step investigations, threat summaries, and remediation guidance in seconds. Available as a standalone experience and embedded directly into Microsoft security tools, it dramatically accelerates incident response and reduces the expertise bar required for complex security analysis.

How does Microsoft Security Copilot compare to other AI security tools?

chevron down icon

Microsoft Security Copilot is an AI assistant purpose-built for security operations, trained on Microsoft's threat intelligence and integrated with tools like Defender, Sentinel, and Entra. Unlike generic AI tools, it understands security workflows and can summarize incidents, generate investigation scripts, and recommend remediation steps directly in the analyst's workflow. Compared to standalone SIEM or SOAR solutions, its tight integration with the Microsoft security stack gives it an advantage for organizations already using Microsoft Defender and Sentinel.
