No idea what he is saying, the term Cyber stock is a widely missused term, Megaport is not and never has been a cyber company. On the question of whether Netlinkz could have prevented these attacks, I dont think he understands either how the attacks have happened or how Net could stop them, Netlinkz is an SDWAN and most of these companies are running SDWANS already so having another will have no impact. They are all runnng these at 256Kbit AES encryption, same as Netlinkz is offering and are using one of the big brands either Cisco or Fortinet. In fact one of them is running this in the virtual mode, not using any equipment from the big brands, using an off the shelf white label hardware and the big companies software.
I cant see what Net offers that they dont offer, so how it could have any additional protection. I also dont think Net has NIST certification.
For people who want to understand this space
https://www.nist.gov/publications/advanced-encryption-standard-aes, this is the US standard which all companies wanting to sell in the US and other markets need to comply with. NIST standard compliance and certification is pretty much the western standard. The European Union Agency for Cyber Security ENISA also require NIST compliance and certification
