I have written about a lot of security tools over the years. I generally prefer to focus on techniques and behaviors rather than tools. Security-minded behavior is generally more effective than security tools. It is easier and vastly more certain, for instance, to conceal a thought that was never committed to text than it is to erase it afterward. Tools can also create a false sense of security and cause a disregard for the importance of security behaviors.
In some instances tools are indispensable, however. Tools can provide capabilities that behavior alone cannot. This post will serve as a repository of my current recommended tools and services. It will host links to my articles/reviews about these products, as well as links to their host sites, and I will update it frequently.
