The Project: 

Cisco Umbrella engineers develop next-generation technologies to secure our customers from a wide range of security threats, malware and inappropriate content. We pioneered the SaaS model in security, and have already launched massively scaled products that are changing the way our customers protect themselves and their users. 

With data centers distributed around the world, Cisco operates at a scale that few other SaaS providers can match. Our Cisco Umbrella product scans billions of web requests every day and applies a range of DNS filtering, heuristics, machine learning, categorization and filtering technology to safeguard against attack. 

Our mission now is to expand on this and build a best of class Secure Internet Gateway that enables businesses to operate in the cloud without fear of compromise, exploitation or accidental data loss. We grow as the web grows, so the challenge is constant. 


Who You'll Work With 

Our team is responsible for a number of highly scalable security services and features in production use or undergoing development. This includes components that inspect hundreds of millions of customer web requests every day for malware and developing new content analysis components that support data loss prevention (DLP). We follow DevOps, we are Agile, we are fast paced, and in constant pursuit of improvement.

Why Cisco 


#WeAreCisco, where each person is unique, but we bring our talents to work as a team and make a difference . Here’s how we do it. 


We embrace digital and help our customers implement change in their digital businesses. Some may think we’re “old” (30 years strong!) and only about hardware, but we’re also a software company. And a security company. A blockchain company. An AI/Machine Learning company. We even invented an intuitive network that adapts, predicts, learns and protects. No other company can do what we do – you can’t put us in a box! 


But “Digital Transformation” is an empty buzz phrase without a culture that allows for innovation, creativity, and yes, even failure (if you learn from it.) 


Day to day, we focus on the give and take. We give our best and we give of ourselves (because giving back is built into our DNA.) We take accountability, we take bold steps, and we take the difference to heart. Because without diversity of thought and a commitment to equality for all, there is no moving forward. 



So, you have colourful hair? Don’t care. Tattoos? Show your ink. Like polka dots? That’s cool.
