Day & Zimmermann

“It was a very successful deployment. Information provided to support groups and end-users was very clear and well thought out making the registration process a success.”
— Phil Long, Director of Enterprise Support and Cybersecurity

Highlights

Duo Security’s agile two-factor authentication solution was an easy sell to the management team, despite already investing in token-based authentication.

Day & Zimmermann chose Duo for its easy enrollment and ease of use across their entire team.

D&Z determined that the cost of purchasing, deploying, and integrating Duo with their systems was more cost-effective than continuing forward with the legacy provider they had already invested in.

The Challenge

Day & Zimmermann (D&Z) is a century-old, family-owned company whose 23,000 employees specialize in construction & engineering, staffing and defense solutions for leading corporations and governments around the world. Operating from more than 150 worldwide locations with 2.5 Billion USD in revenue, Day & Zimmermann is currently ranked as one of the largest private companies in the U.S. by Forbes.

Their focus

Whether it’s running the operations & maintenance at a U.S. power plant or helping to build a new command and control headquarters with sustainable design for the US Air Force, D&Z strives to solve customers’ most complex and technical challenges with dynamic talent, proven industry expertise, and customized outsourcing solutions.

To solve those challenges, D&Z provides customized outsourcing solutions, alleviating their customers’ management and operational load so that they can focus on their core operations. With hundreds of utility, nuclear power and government customers, D&Z knew they needed to find an easy and effective security solution to protect their customers.

Lance Honer, Manager of Cybersecurity at Day & Zimmermann, was tasked with deploying two-factor authentication after he joined the company. His predecessor had started working with a legacy two-factor authentication provider, and had already purchased tokens by the time Lance was hired.

Finding a Better Solution for the Company

Lance became frustrated with the deployment process for the legacy two-factor solution, noting that technical support and documentation were lacking.

In addition to the difficult setup process, the legacy two-factor solution forced users to log into a browser in order to access their VPN, while previously they were used to logging in via the VPN client.

With nearly 1,000 employees using two factor for their Cisco VPN, the change in login behavior would have been disruptive to the company’s workflow.

The legacy solution they purchased didn’t offer the variety of authentication methods Lance needed for his many users’ needs and preferences.

The Solution

Having researched Duo Security in the past, Lance knew the variety of authentication methods Duo offered was a necessary feature for D&Z. Duo’s two-factor authentication solution can be installed on phones as an app using Duo Mobile, and also supports a multitude of additional authentication methods -- Duo Push, SMS, voice and hardware tokens.

A Smooth Duo Deployment

The deployment and setup process with Duo went well for D&Z. “I was blown away by how smoothly it went,” said Lance. “For the most part, we haven’t gotten much feedback from our end-users. We haven’t gotten any complaints about using it. It’s not cumbersome or intrusive.”

“It was a very successful deployment,” said Phil Long, Director of Enterprise Support and Cybersecurity for Day & Zimmermann. “The information provided to support groups and end-users was very clear and well thought out making the registration process a success.”

How has it been working with Duo’s two-factor solution to date?

“Overall, it’s been a phenomenal experience from my standpoint,” said Lance.
