Pros
This company is great to work for because it is full of incredible talent and has a great culture. No matter how technical or obscure of a question I have, one of my colleagues likely has an answer or can help me out. The company is young and growing quickly thanks to the immense amount of talent. One of the company's core values is, "Don't be a jerk!" and it shows in almost every single interaction I have had with my colleagues. Everyone is good at something and together we accomplish some pretty awesome things. This company is strictly an information security company, so their services and offerings aren't diluted with unrelated distractions.
Cons
Not so much a con, but the company is largely virtual so your boss might be in another state or time zone. There are ways to work around this, but it's not a typical office-environment. This might be a con for some, but this is a work hard, play hard kind of company. People here do whatever it takes to get the job done, and done right, even if that means working late hours when needed. This is not the place you come to work straight-8's and skate.
