Cyber Security Training Courses

Many of these courses are costly, especially if you are paying out of your own pocket. The primary advantage of a training course from the big 3 providers (SANS, Offensive-Security, eLearnSecurity) is that you get a lot of learning packed into a minimal amount of time. All have included labs that force you to make sure you understand the content.
Provider Course Cost Cert Focus Notes
SANS SEC504: Hacker Tools, Techniques, Exploits, and Incident Handling GCIH PentestDFIR A gentle introduction to hacker tools and techniques with a focus on Incident Handling. Identify an incident, securely handle forensic evidence and use a structured methodology to work through the incident. Great for people with a technical background but little experience in hacking techniques and cyber security.

Whether you are on the job, working in your lab or training, these Linux based Cyber Security distributions will save you time. Essentially a collection of preinstalled hacking tools. Which one is your proffered choice?
Provider Name Notes
SANS Slingshot Linux A distribution similar in focus to Kali Linux this one has been developed by SANS. Often a pre-requisite for use with the training material in the SANS courses.
SANS Kali Linux Without a doubt, the most well-known penetration testing Linux distribution. The history of this distro can be traced back to Linux hobbyists of ages past (knoppix -> whoppix -> whax -> backtrack -> kali). Developed and maintained by Offensive Security.
SANS SIFT Linux Another distribution maintained by SANS and used in their courses. This one is interesting for those who usually stick to Kali as it contains many different tools due to its focus on DFIR (forensics and incident response).
NA Tails Linux A privacy focused distribution. Its primary goal is sending all the traffic from the virtual machine through the Tor anonymization network. Mozilla and the Tor project have been sponsors in the past. It is supported by various non-profit groups.
