The state body in Portugal to which telecoms operators, banks, hospitals and municipalities report cyber attacks and outages affecting many people. It also runs the national response team CERT.PT and issues warnings about new threats.
Where you come across it. company statements after an attack ("the incident has been reported to CNCS"), news about outages in government systems.
If you lose internet access, CNCS is not the place to complain: that is what your provider and ANACOM are for. CNCS is notified of the attack itself, not of its consequences for an individual customer.
