About Bolster
Bolster turns the security paradigm upside down and removes threats and digital risks before an attack occurs. Our protection extends beyond the enterprise to customers and partners. Our approach is the antithesis of today’s cyber defense strategy, which is to wait for an attack than try and prevent it. Or worse, assume you have been breached and hope you can detect it. We leverage the power of AI to apply deep learning, computer vision, and natural language processing to identify criminal intent on millions of web pages daily. We tirelessly monitor the Internet to find malicious web pages that could cause harm and remove them. We empower companies to take back control of the Internet by continuously eliminating the threats that threaten their business, customers, and brand.
We are just getting started, and the future could not be more exciting. We’re growing the team in all functions as we transition from a small start-up into the next phase of our journey. We are looking for A-list talent who will have a meaningful impact, solve new challenges, and take ownership of the future of Bolster. If this is you, apply and join our team!
