The more likely story is the IT team used this as a way to try to get more budget because politicians don’t respond to anything else (whether or not the budget is justified, impossible to say from the outside). Or they were incompetent and truly believed their firewall was measuring attacks and they stopped them all.
Overloaded servers likely is just bad engineering because there’s many tools (many/most free or incredibly cheap) to help with that. Heck, SO, one of the most trafficked sites on Earth, ran on a number of Xeon machines. I suspect their IT infrastructure was poorly optimized.
Honestly there is merit to the claim in my opinion. The security industry is full of scam, now even formerly reputable providers begin to sell very flawed solutions. But internal IT is not part of that.
It is also a care about doing a sensible risk analysis. Your web server should maybe be isolated from critical systems as any other system the public can interact with.
He said this in an interview with LB.ua [1].
"I think the role of cybersecurity is a bit exaggerated. There is a lot of talk about it, but in fact few can name any real cases of cyber threats. Let me give a simple example. When we came to the President's Office, the IT team showed dashboards with a thousand attacks a day, overloaded servers, etc. Two weeks later, we fired them, and nothing happened for several months while we were assembling a new team." - Fedorov said.
