"Getting started with Malvertising Defense was like a dream. Since it was installed, we haven't had any issues at all. We have almost gotten to the point where we forgot the problem ever existed at all."

“The best part about Malvertising Defense is how quickly and easily we can onboard new publisher sites. It takes about 10-15 seconds to install the script on our publisher websites, and they are instantly protected.”

System1 has always been well aware of how widely malvertising plagues the digital advertising industry and the need to keep it at bay for users. For this reason, the team at system1 never struggled with the decision of whether or not to use anti-malvertising products for display advertising. But they did hit roadblocks once they found that most anti-malvertising products on the market also harm publisher revenue and site latency.

Their challenge was finding a solution that balanced user safety, yield recovery, and site performance. Most of the products on the market block malicious ads, which also block the publisher’s ability to generate revenue for those impressions.

System1's malvertising problem found its match in HUMAN’s Malvertising Defense solution, fulfilling the publishing team's dual desire for user safety and revenue recovery. 

Among various options, Malvertising Defense emerged as the perfect fit, exceeding expectations. Head of Digital Ad Strategy, Lila Hunt, praised Malvertising Defense for its unique capability to hold malicious actors accountable, ensuring they pay for the ad inventory they claim. 
This key differentiator sets Malvertising Defense apart from other solutions, where potential revenue losses may occur due to indiscriminate blocking. The cost-benefit analysis overwhelmingly favored Malvertising Defense, ticking all the boxes on System1's requirements for a robust anti-malvertising provider.

Remarkably, Malvertising Defense was not considered a mere cost center but was recognized as an indispensable tool for revenue preservation by System1's publishing team, elevating its significance to a strategic asset.


For the System1 publishing team, an unexpected benefit of using Malvertising Defense is knowing that they're doing their part to make malvertisers’ efforts less effective by decreasing their campaign ROI, as well as these key benefits:

  • Ease of Implementation: One of the most important benefits that System1’s busy publishing team gets from Malvertising Defense is that it truly is a “set it and forget it” solution. Since installing Malvertising Defense, the System1 team has rarely, if at all, had to think about malicious redirects.
  • Direct Customer Service: While Malvertising Defense’s set-it-and-forget-it solution might make it seem as though regular communication with the HUMAN team wouldn’t be needed, it has actually been one of the most important benefits System1 has found from working with HUMAN.

For the System1 team, HUMAN has set a new bar for what they expect from their partners and solution providers.

The Malvertising Defense solution has helped to solve malvertising problems and doles out justice to the bad guys, which is just the cherry on top of an already great relationship.
