90-Year-Old Credit Union Reduces Average Handle Time 66% in First 90 Days of Pindrop Implementation

Before Pindrop® Solutions

Account takeovers were on the rise for this credit union. For example, potential fraudsters were repeatedly calling in using spoofed numbers. As a first step, the credit union wanted to understand if a repeat caller was targeting them, and second, they wanted to detect fraud when it was happening. The credit union’s Assistant VP of Digital Services shared, “We had one fraudster who called in requesting a line of credit for $30,000. They did this by moving the money out of a member account and into a shell account using the member’s information. Bad loans were also rampant because members easily bypassed the Knowledge-Based Authentication questions (KBAs). And, this was just the fraud that we knew about.”

Although fraud was rising, the credit union was determined to find the right solution and justify the cost. However, they knew that call center agents were uneasy, acting as the front line for fraud, and they were losing agents. 

The credit union was aware of the evolving fraud landscape, where the human ear can no longer be relied on to detect a synthetic voice. With the proliferation of generative AI, easy accessibility to AI voice engines (+800% increase from ‘23 to ‘21)1, and low cost to use, the way we see and hear content has irrevocably changed. Today, the ability to manipulate audio is easy, and humans are unable to tell the difference. For example, in a study by the International Security Program, human detection of AI generated audio was labeled ‘as good as a coin toss’ , detecting fake audio with just 54.5% accuracy (compared to 62% accuracy for fake images). Traditional methods used by organizations like KBAs and one-time passwords (OTPs) are also vulnerable to synthetic audio attacks.

What ROA did Pindrop® Solutions deliver?

“Once we implemented the Pindrop Passport and Pindrop Protect solutions, things took off.” 

Since deploying Pindrop’s fully integrated authentication and fraud detection solution, the credit union has significantly reduced the success rate of fraud within its phone channel, seeing a 50% reduction in the number of fraud incidents overall.

Launched in September, 2023
Once implementation was complete, the credit union was surprised to see how many fraud attempts were happening; it was considerably more than they initially thought. 

When Pindrop® Protect and Pindrop® Passport were turned on, credit union members were initially apprehensive; they no longer had significant hurdles, such as answering lengthy questions,  to clear when getting through to the credit union. For example, within the first two months, the credit union went from an average of 54 seconds to identify/ validate a member, down to 18 seconds on average. Member satisfaction improved significantly, and average handle time was reduced, which meant average wait time also decreased. In fact, the credit union observed a 67% decrease (36 seconds) in time to authenticate members.

Additionally, the credit union’s agent experience improved dramatically, reducing overall agent attrition in just 90 days. For example, after launching Pindrop  Protect and Pindrop Passport in September, the credit union’s employee turnover was the lowest they had ever seen in December, just one quarter after implementation.

Since the deployment of Pindrop Protect, the credit union has experienced an 88% reduction in fraud incidents occurring within their call center channel. In one month alone, Pindrop Protect detected nine fraudulent calls against an alert rate of 0.68% and a review ratio 241:1. 

Since the deployment of Pindrop Passport, the credit union authenticated 23,188 calls, and low-risk authenticated an additional 11,132 calls. In one month, Pindrop Passport demonstrated an increase of 1.54% in enrollment penetration (0:6min), which measures the percentage of calls tied to previously enrolled identity claim vs the call population with an identity claim.

Not Just ‘Another Vendor’ 

Don’t take our word for it, the Credit Union shared their experience with the Pindrop implementation as well as their experience  with our team: 

“The ongoing support from the Pindrop team has been outstanding- they are extremely easy to work with, and they always deliver on their word. The service provided is white glove and turnkey. They are by far one of the most flexible and understanding vendors that we have worked with. Their team took the time to ensure that all stakeholders were armed with the information necessary to ensure that we could hit the ground running. Throughout the entire process, they answered our questions thoroughly.”

“In fact, Pindrop makes us aware of additional features that we might not be taking advantage of that are included based on the contract we have, like Custom Attributes. That is not something that you would expect from a vendor. This kind of service is what truly sets Pindrop apart from others.”
