Job description

About PUNCH:

We’re problem solvers first & foremost. PUNCH’s origin story involves frustration with available INFOSEC tools and techniques—we came up thru the industry using these inefficient tools and techniques and decided there had to be a better way. We bring this laser focus on efficiency to every customer engagement.

We have trust as a hallmark in everything we do. PUNCH provides its team members with the maximum amount of ownership over their careers, the direction of the company, and the flexibility & freedom to accomplish their job without interference. Trust requires accountability; we live that, company-wide.

We back each other up. PUNCH is a supportive place to work. We’ve worked hard to create an environment that makes people better, encourages team work, and rewards a “pitch in” mentality.

We give back. To those in need. To the community. To the industry.
