Sapio Research Survey: 20% have SD-WAN project, but 48% of those are proof of concept
In a survey of 200 senior IT and networking managers in the US and the UK, Sapio Research found 20% of respondents said they have a software-defined WAN project in progress,
while 32% haven’t explored the technology and 27% may look at it in the
future. About one-third of respondents said they wanted to reduce
network costs and to better manage their network infrastructure. The
research study found that 48% of those are running SD-WAN proof of
concept at select sites or other limited deployments. That means only about 10% are transitioning fully to SD-WAN.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use. Access this neat software over on github: easywall

I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
