Our Story


While running security engineering at Etsy we were often faced with the fact that security products on the market didn’t solve real world problems we encountered every day. The more we talked with our peers, the more we heard the same frustrations repeated across organizations and industries. We founded Signal Sciences to deliver pragmatic and effective solutions that counter the threats companies face on a daily basis. We know the challenges you’re facing because we’ve been there, and we’d like to help.

We're Hiring!


We started Signal Sciences to take our experience defending high traffic organizations and use it to solve interesting problems in Internet security with fun people.

We’re growing our Engineering and Sales teams in Venice Beach. While experience in security never hurts, you'll have plenty of opportunity to learn those skills here working with the rest of the team.
