Stop Spoofed Calls and Prevent Fraud with SENTRY® Call Blocking Solution
Spoofed calls harm your clients.
Spoofed calls deceive customers into trusting fraudulent callers pretending to represent your business, aiming to steal sensitive information.
Financial services and healthcare providers are particularly vulnerable to spoofed calls and fraudulent activity.
What if there was a product that offered spoof protection against bad actors and blocked spoofed calls before they ever reach your clients?
SENTRY® Call Blocking is your frontline defense against defrauding your loyal customers and harming your brand reputation.
The True Cost of Spoofed Calls
Spoofed calls can lead to significant financial losses for clients, especially in industries like banking, healthcare, and insurance.
Lost Money
Spoofed calls significantly impact consumers and financial institutions, especially in the U.S.
According to LexisNexis’s True Cost of Fraud Study, for every $1 lost by consumers to fraud, banks in the U.S. lose $5.75. That’s because when fraud occurs, banks aren’t just liable for the money lost. There are also fees and interest costs incurred during the application/underwriting/processing stages. You also have to consider fines and legal fees, labor and investigation costs, and external recovery expenses.
The financial services industry isn’t the only one that’s suffering from scammers running wild. In First Orion's healthcare report, nearly 75% of respondents reported being scammed for some financial loss. Many of those respondents, almost 6 in 10, said they had lost at least $250 due to a healthcare scam!
Lost Reputation
Spoofed calls damage your brand reputation, prompting customers to choose competitors who better protect their communication.
How your customers see your brand is a crucial factor when making a purchasing decision, especially for healthcare customers. Nearly 8 in 10 respondents said that if a healthcare provider did not properly identify their calls, they would consider leaving a negative review.
Customers don’t like it when you call without branding your number. How do you think they’ll respond if they get tricked into answering a call that’s not really you? A spoofed call is a bad look for your brand and terrible for your reputation.
