If you receive an unexpected request to move funds, change payment details or share account information, verify it through a known contact method before responding. Fraudsters often create urgency to bypass your normal review process.

Fraud protection services from Connect
Explore what’s available in Connect to help protect your accounts from unauthorized transactions.
ACH debit block
Block all ACH debit transactions from your accounts or specify which vendors are authorized to collect payments—ideal if you regularly use ACH and want additional protection against unauthorized debits.
Check protection services
We review checks presented for payment against the information you provide and flag any discrepancies as exceptions. Commonly referred to as Positive Pay, this service works well if you manage a high volume of checks or have multiple employees writing checks on your behalf.
Check monitoring
Set a dollar amount threshold and we ll flag any checks at or above that amount for review. Commonly referred to as Reverse Positive Pay, this service works well if you typically write checks to routine vendors or under a certain amount.
Access & Security Manager
Delegate cash management tasks to your employees while maintaining the control you need. You can set user permissions, manage access levels and monitor account activity directly within Connect.
Cybercrime and your business
Cyber threats targeting businesses are growing more sophisticated. Understanding the tactics behind fraud schemes—from phishing emails to business email compromise—is one of the most effective ways to protect your accounts.
3 Protection Tips
Review your account activity and exception reports frequently. The sooner you identify an unauthorized transaction, the faster you and your J.P. Morgan team can work to address it.
Never share your login credentials, full account numbers or one-time passcodes with anyone—even if they claim to be from your bank. J.P. Morgan will never ask you for this information by phone, email or text.
