The Signal Sciences Solution

We make web applications more secure. Simple as that. And we do it by providing an unparalleled platform that teams actually want to use. It’s flexible, exceptionally elastic, collaborative—and protects business initiatives like DevOps and cloud adoption without disrupting current workflows and processes already in place.

We are practitioners first and vendors second.

How we got here.

Our story begins at Etsy, where our founders were running security and growing increasingly frustrated with existing legacy technology that neither met flexible development needs nor provided useful attack data. So they built their own.

Our relationship to customers:

  • Helping Duo securely verify users’ identities for applications
  • Protecting OneMedical’s sensitive patient data and application from any malicious attacks while maintaining HIPAA compliance
  • Making sure Taser continues to influence public safety while protecting sensitive data
  • Aiding Honest Dollar in setting up retirement-savings programs for small businesses
