Our company has threats daily.
That's called the Internet. If it's connected and there is a service exposed it gets reconnaissance probes, vulnerability scans, and exploit attempts. It has happened since day one. Distributed attack infrastructures can be rented for cheap. Need a good firewall (Layer 3 and 4) with IDS and IPS and, in the case of a web service for example, a WAF (Layer 7). Sitting behind a CDN with DDoS protection, such as Cloudflare, has big benefits. They can even be used to the degree of not exposing your own addresses to the public Internet - the addresses are only accessible via the CDN meaning only filtered traffic gets proxied.
