Introduction : The IT network, the nervous system of your infrastructure
Within a company, the IT network functions like the circulatory system of the digital infrastructure. It allows data to flow, connects users, provides access to critical applications, and ensures service continuity.
A high-performing and secure network is essential in a context marked by :
- The rise of remote access (telework, VPN, cloud)
- The increase in data volume to be processed
- The need for very low response times for some critical applications
A poorly sized, poorly protected, or poorly configured network leads to performance losses, outages, or even major security breaches.
Network security : anticipating threats to protect critical systems
With the rise of cyberattacks, network security has become an absolute priority. A breach in network access can compromise your entire information system.
Today, companies must implement advanced firewalls, Network Access Control (NAC), segmentation, and intelligent filtering solutions to reduce risks.
At the same time, it is crucial to protect against DDoS attacks, which aim to saturate network resources and make them inoperable.
A good network cybersecurity policy is based on :
- A dynamic mapping of flows
- Real-time monitoring
- Scalable solutions adapted to your size and industry
Network access : controlling who accesses, when, and how
Network access control is now a central issue. It is no longer just about granting or denying access to a user, but about verifying the compliance of their device, contextualizing the access request, and tracking activity.
Zero Trust models or role-based segmentation are increasingly deployed in modern architectures.
This requires the implementation of :
- Strong authentication (MFA, SSO)
- Real-time behavioral analysis
- Granular access rights rules
These tools reduce the attack surface and enable a quick response in case of an incident.
