How Real-Time Validation Can Stop Business Email Compromise Before It Costs You
Business email compromise (BEC) has evolved from simple phishing into a sophisticated threat that now uses deepfake audio, video, and AI-generated text to impersonate executives and vendors. According to the FBI’s Internet Crime Complaint Center (IC3), BEC has caused over $50 billion in global losses since 2013, and a 2026 report from Trustpair found that 71% of U.S. companies report an increase in attacks. Traditional email security filters are no longer enough. One emerging defense that large institutions like J.P. Morgan are already using is real-time validation of payment requests and sender identities.
What Happened: The Rise of BEC and Real-Time Validation
In a typical BEC attack, a criminal spoofs or compromises an executive’s email account, then sends a fraudulent payment request to someone in finance. The request often looks legitimate—correct tone, internal jargon, even matching email threads. With the help of generative AI, attackers can now create convincing voice deepfakes to follow up with a phone call, making the scam even harder to detect.
Real-time validation is a method that adds a second layer of verification at the moment a payment is initiated. Instead of relying solely on email instructions, the system automatically checks the payment details—such as the recipient bank account number—against a trusted database. It can also trigger an out-of-band confirmation, like a phone call to a known number or a text message to a pre‑registered device, before funds move.
J.P. Morgan has publicly described how it uses real-time validation to protect clients. The bank’s approach combines behavioral monitoring of payment patterns with verification of account changes. For example, if a vendor suddenly changes its bank account details, the system flags the change and requires confirmation through a separate channel before processing. J.P. Morgan also warns that deepfake fraud is an emerging variant and recommends that businesses verify any urgent payment request via a known phone number, not the one provided in the email.
This is not a silver bullet, but it is a practical layer that can stop many attacks before they succeed.
Why It Matters: Why Traditional Email Security Is Not Enough
Most companies rely on email filtering, employee training, and maybe multi‑factor authentication for email access. But BEC attackers don’t need to break into your email system—they can simply impersonate a trusted partner using a look‑alike domain or a compromised account at another company. Filters might catch a suspicious domain, but they struggle with genuine accounts that have been taken over.
Real-time validation addresses the core weakness: the gap between what the email says and what is true. By verifying payment instructions against an independent source of truth, you remove the attacker’s ability to exploit that gap.
The Trustpair survey reported that 71% of U.S. companies are seeing more BEC attacks, and many say AI makes detection harder. Without real-time validation, the burden falls entirely on human judgment—and people make mistakes under pressure.
What Readers Can Do: Practical Steps for Your Organization
Even if you don’t have the budget of a large bank, you can implement real-time validation with relatively simple tools and policies:
Establish a payment verification protocol. For any payment over a threshold (say $5,000), require a phone call to a known number to confirm the request. Do not use the phone number in the email; use one you have on file.
Use payment confirmation software. Many accounting platforms and banks now offer real‑time account validation. Ask your bank if they have a service that automatically checks beneficiary account details against a database before releasing funds.
Flag changes to vendor details. If a supplier notifies you of a new bank account or address, treat that as a high‑risk event. Require verbal confirmation from someone you know at that company, using a number you already have.
Monitor payment patterns. Look for unusual timing, amounts, or recipients. Simple alerts can catch deviations even if the email itself looks legitimate.
Train finance staff on out‑of‑band verification. Make it a non‑negotiable habit to confirm any instruction that involves money movement, especially if it’s urgent or comes from a senior executive.
Consider deepfake awareness. Deepfake audio and video are becoming more common. If you ever receive a voicemail or video call from a leader asking for an urgent wire, treat it with extra skepticism. Use a second method to verify.

Real-time validation won’t stop every attack, but it raises the bar for criminals and buys your team time to spot the lie. The key is to build verification into your payment workflows, not to rely on hope alone.
