About Zscaler

Zscaler (NASDAQ: ZS) accelerates digital transformation so that customers can be more agile, efficient, resilient, and secure. The Zscaler Zero Trust Exchange is the company’s cloud-native platform that protects thousands of customers from cyberattacks and data loss by securely connecting users, devices, and applications in any location. 

With more than 10 years of experience developing, operating, and scaling the cloud, Zscaler serves thousands of enterprise customers around the world, including 450 of the Forbes Global 2000 organizations. In addition to protecting customers from damaging threats, such as ransomware and data exfiltration, it helps them slash costs, reduce complexity, and improve the user experience by eliminating stacks of latency-creating gateway appliances. 

Zscaler was founded in 2007 with a mission to make the cloud a safe place to do business and a more enjoyable experience for enterprise users. Zscaler’s purpose-built security platform puts a company’s defenses and controls where the connections occur—the internet—so that every connection is fast and secure, no matter how or where users connect or where their applications and workloads reside.

Avalor is applying its data expertise to security, enabling companies to better understand and manage risk. We have both a rich data platform and security modules that tap into the platform to provide immediate benefits to our customers. We have built and patented a Data Fabric for Security™. It curates data from hundreds of security and business tools and contextualizes that data to help companies understand and address their riskiest problems. Our Unified Vulnerability Management module is our first module to tap into the power of our data fabric, enabling companies to create custom contextualized risk scores and tailored workflows to reduce risk.


If you're passionate about data models and helping companies improve their security posture, we'd love to have your talents here at Avalor as we work to make the world a more secure place.
