We Are Cisco

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

We embrace digital, and help our customers implement change in their digital businesses. Some may think were old (30 years strong!) and only about hardware, but were also a software company. And a security 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 cant 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, we give our egos a break and we give of ourselves (because giving back is built into our DNA.) We take accountability, we take bold steps, and we take difference to heart. Because without diversity of thought and a commitment to equality for all, there is no moving forward.

So, you have colorful hair? Dont care. Tattoos? Show off your ink. Like polka dots? Thats cool.
