Global Contractor Day & Zimmermann Selects Signal Sciences Next-Gen WAF for Superior Web Defense of 3rd-Party Developed Apps with Lowest TCO

Day & Zimmermann has implemented Signal Sciences next-gen WAF to protect external and internal web applications and provide visibility and protection over a key part of their business
LAS VEGAS, (Black Hat 2018 Conference)   -

Global provider of construction & engineering, staffing, security and defense solutions, Day & Zimmermann, has implemented Signal Sciences next-gen WAF to protect external and internal web applications, providing visibility and protection over a key part of their business. Signal Sciences CEO Andrew Peterson said, “We are excited to bring on such a well-established brand from another set of industries which demonstrates that production web defense is a key part of risk mitigation within any enterprise.”

Day & Zimmermann provides advanced talent and technical solutions in complex work environments across a very diverse set of industries for leading corporations and governments around the world.
As part of its operations, leadership made strategic investments in digital transformation via third party web applications to accomplish core business functions. In keeping with their security strategy, they prioritized the protection of these modern, dynamic web applications as part of a 2018 initiative.

With a cybersecurity team led by Lance Honer, Day & Zimmermann had certain goals in mind: find a product that didn’t require a lot of effort to install, and one that didn’t require thorough knowledge of the application to operate and maintain, since many of the applications are not built internally. Given Honer’s previous experience with traditional WAFs, he knew that managing regular expression (regex) based signatures would create a burden for him and his team. This would require him to allocate resources and time to learn and scale, taking away focus from other key security areas. Signal Sciences not only offered quick installation, but also could be integrated into their application deployment systems. This enabled automated updates to all production systems within five minutes.

After a quick implementation of Signal Sciences initially in a staging environment, Honer decided to put the solution to the test in production to coincide with a penetration test — to test the effectiveness of both Signal Sciences and the pen testers. Anything the pen testers tried to hit got blocked immediately by Signal Sciences, sealing the deal for final selection and procurement.

“We’re a very typical IT organization—we’re not bleeding edge, but we recognize the need to shore up our risk from externally facing websites, where we previously didn’t have visibility. The Signal Sciences install went so incredibly quickly and easily, and demonstrated immediate value right out of the box,” said Manager of Cybersecurity, Lance Honer. “It provided us with a solution that wasn’t regex based, since we didn’t have detailed knowledge of inputs to the application to compose legacy WAF regex signatures.”
