Why Business Banking Security Matters

Business banking accounts are prime targets for fraudsters because they typically hold larger balances and process higher-value transactions than personal accounts. Unlike consumer accounts, business accounts have different liability protections — making it critical to implement strong security measures proactively.

This guide covers the security features available through your Eastern Business Banking login and the best practices your organization should follow to protect your financial assets.

Multi-Factor Authentication (MFA)

Multi-factor authentication is the single most effective security control for preventing unauthorized account access. Eastern Business Banking requires MFA for all users.

How MFA Works

When you log in, you provide two pieces of evidence that you are who you claim to be:

Even if a fraudster steals your password, they cannot access your account without the second factor.

MFA Delivery Methods (Ranked by Security)

MethodSecurity LevelNotes
Authenticator App (TOTP)⭐⭐⭐⭐⭐ HighestGoogle Authenticator, Microsoft Authenticator, Authy. Code changes every 30 seconds. Not vulnerable to SIM swapping.
Hardware Token⭐⭐⭐⭐⭐ HighestPhysical device that generates codes. Most secure but requires carrying a separate device.
SMS Text Message⭐⭐⭐ ModerateConvenient but vulnerable to SIM swapping attacks. Better than no MFA.
Email⭐⭐ LowerIf your email is compromised, MFA is bypassed. Use only as last resort.
Phone Call⭐⭐ LowerVulnerable to call forwarding. Use only if no other option is available.
Eastern Bank strongly recommends using an authenticator app for MFA. SMS-based MFA is vulnerable to SIM swapping attacks, where a fraudster convinces your mobile carrier to transfer your phone number to their device.

Managing MFA Settings

To update your MFA delivery method:

  1. Log in to Eastern Business Banking
  2. Navigate to Settings → Security → Multi-Factor Authentication
  3. Select your preferred delivery method
  4. Follow the setup instructions for your chosen method
  5. Test the new method before relying on it

If you lose access to your MFA device, contact the Business Service Team at 1-800-333-8000 to reset your MFA. You will need to verify your identity through alternative means.

Best Practices for User Management

Positive Pay — Check and ACH Fraud Prevention

Positive Pay is Eastern Bank's fraud prevention service that matches presented checks and ACH debits against your authorized list before payment.

Check Positive Pay

When you issue checks, you upload a file (or manually enter) the check number, amount, and payee to Eastern Business Banking. When a check is presented for payment, Eastern Bank compares it to your authorized list:

ACH Positive Pay (ACH Filter)

ACH Positive Pay allows you to pre-authorize specific ACH debits:

Contact the Business Service Team at 1-800-333-8000 to enable Positive Pay for your account.

Phishing and Social Engineering Protection

Phishing attacks are the most common method used to compromise business banking accounts. Fraudsters impersonate Eastern Bank or other trusted entities to steal credentials.

Recognizing Phishing Attempts

Business Email Compromise (BEC)

BEC attacks target businesses that regularly make wire transfers or vendor payments. Attackers compromise or spoof email accounts to redirect payments:

BEС Prevention

  1. Verify all banking changes by phone — call the vendor using a known number (not from the email)
  2. Implement dual approval — require two people to approve wire transfers
  3. Use out-of-band verification — confirm payment instructions through a different channel than email
  4. Train employees — educate staff on BEC tactics and red flags
  5. Register domains — consider registering look-alike domains to prevent spoofing
Eastern Bank will never email you asking for your password, account number, or security questions. If you receive such an email, do not respond and forward it to abuse@easternbank.com for investigation.

Device and Network Security

Secure Your Devices

Mobile Security

Session Security

Eastern Business Banking implements several session-level security controls:

Alerts and Notifications

Eastern Business Banking provides configurable alerts to keep you informed about account activity:

Alert TypeTriggerDelivery

Failed login alertMultiple failed login attemptsEmail
Payment alertPayment or transfer initiatedEmail, SMS
Balance thresholdAccount balance falls below a set amountEmail, SMS
Large transactionTransaction exceeds a specified amountEmail, SMS
Profile changeUser permissions or settings modifiedEmail

Configure alerts in Settings → Alerts. Enable as many alert types as practical — early detection is critical for limiting fraud losses.

What to Do If You Suspect Fraud

If you notice unauthorized transactions, receive suspicious emails, or suspect your credentials are compromised:

  1. Change your password immediately — if you can still log in
  2. Call the Business Service Team — 1-800-333-8000 (available 24/7 for fraud reports)
  3. Request an account freeze — stop all outgoing transactions
  4. Document everything — transaction details, times, emails received
  5. File a police report — for significant fraud losses
  6. Review all recent transactions — look for additional unauthorized activity
  7. Update MFA — reset multi-factor authentication on a trusted device
  8. Notify your IT team — check for malware or compromised systems
The sooner you report fraud, the more likely Eastern Bank can recover the funds. Wire transfers become irrevocable within hours, so immediate reporting is critical. Do not wait to "investigate" — call first.
