SENTRY Call Blocking: Prevent Spoofed Calls and Protect Your Brand

SENTRY® Call Blocking: Prevent Spoofed Calls and Protect Your Brand

Updated Feb. 20, 2026

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.

SENTRY – The Ultimate Spoof Protection Solution

Scam calls are rising, and First Orion combats them by analyzing billions of calls annually to label fraudulent activity and protect customers.

Our call protection experts use AI and machine learning to analyze more than 100 billion calls annually and label 19 billion calls yearly.

This dire situation demands SENTRY, the ultimate spoof-proof solution for outbound calls.

SENTRY is a spoof-blocking solution that integrates seamlessly with your current calling solution.

It empowers you to block spoofed calls of your business’s numbers, ensuring that only legitimate calls reach the end user’s mobile device.

How Does SENTRY Work?

SENTRY blocks spoofed calls before they reach customers, preventing fraud by stopping these calls at the network level. Using advanced call verification to ensure only legitimate calls reach customers, SENTRY works silently in the background to block spoof attempts. With SENTRY added to your call and contact technology stack, you can ensure that spoofed calls won’t reach your customers.

Who Can Benefit from SENTRY Protection?

SENTRY is the perfect spoof-proofing solution for enterprises with high call volumes that deal with sensitive customer information. Financial services like banks, credit unions, and tax prep services benefit by protecting their numbers from spoofers.

Healthcare organizations and insurance providers can also safeguard their clients’ sensitive information with SENTRY. That includes social security numbers, addresses, bank account numbers, test results, and more.

And thanks to our analytics available through the Customer Portal, you get more insight into how many of your calls are being spoofed. When you know which calls are being spoofed, you know which numbers are being targeted by scammers and need SENTRY protection.

First Orion’s telephone number management expertise enables your business to protect the right numbers from scammers.
