Discord
Cyber Insecurity is a wonderful community blending cybersecurity professionals and people aspiring to break into the industry. I am an active member of this community and I have made many friends and learned through my connections from Cyber Insecurity. Everyone on this server is friendly and pushes you to be the best you can be. There are rooms for the red team, the Blue team, and even a room for when you need to fight imposter syndrome. I hope you see you there!
The Certification Station is excellent for finding a ton of resources for the certification that interests you. More importantly, it connects you with people that are studying the same exam as you. Also, all the people that passed the exam will pass on the tricks they learned along the way.
The Cyber Mentor is a great resource for cybersecurity and Pentesting. He shares a lot of information for free every day and he has classes that are inexpensive. On this server he offers a lot of giveaways, so be on the lookout for them!
The Cisco Study group is great for anyone who is looking to pass the CCNA or CCNP. They have rooms dedicated to these certifications. Also, they have rooms for Juniper, Linux and so much more. If you looking for all things related to Cisco this is the server to join.
The Cybersecurity Student server has a lot of good resources. They have rooms dedicated to both Hack The Box and Try Hack Me. It is also a great server to communicate with people that are also pursuing a career in cybersecurity.
