DryRun Security was established from our vast experience training over 10,000 developers and security professionals in application security testing, alongside our involvement in developing security products for companies like GitHub and Signal Sciences. This extensive background allowed us to recognize a crucial gap in the market: the absence of tailored security context for developers. Given that developers frequently modify code during their daily tasks, they need a security solution that delivers pertinent insights, which in turn helps them work more effectively and securely. Conventional security code reviews often disrupt development teams, typically taking place too late in the production process. Thus, it is vital for developers to obtain security context as soon as a pull request is made, enabling them to grasp the potential ramifications of their code alterations. Until now, most security testing approaches have relied on a uniform method, which has resulted in significant frustration among developers due to the flood of repetitive alerts and inconsistent results. By prioritizing the delivery of actionable security context at critical junctions, DryRun Security aspires to transform how developers integrate security into their daily workflows, ultimately fostering a culture of secure coding practices. This innovative approach not only enhances the development process but also aims to reduce the likelihood of vulnerabilities slipping through unnoticed.
