Cisco is at the forefront of security against quantum cyber threats, but not immune to vulnerabilities.

Recent events perfectly illustrate this paradox. On the one hand, the deployment in Switzerland of a "quantum-safe" network with ID Quantique demonstrates that Cisco remains a cutting-edge technology leader. On the other hand, serious warnings about sophisticated cyberattacks serve as a reminder that even the best equipment has its vulnerabilities.
🔍 My feedback:
Throughout my career as an IT Director, I have often chosen to limit the number of Cisco devices within our infrastructures. While their performance is undeniable, they require complete mastery and expertise to guarantee true long-term security.
Implementing Cisco without absolute rigor exposes oneself to a complexity that one can no longer control.
🛡️ My advice:
Outsourcing your infrastructure is not simply a matter of "technical specifications". Beyond the equipment, you absolutely must assess the actual skills of the engineers, whether they are internal or from your service providers.
The tool's performance will never replace the expertise of the person configuring and monitoring it. Cutting-edge equipment in insufficiently trained hands is a risk, not a protection.
Cybersecurity is a balance between disruptive technology (like quantum computing) and human operational rigor.
And how do you audit the technical expertise of your network providers?
