Security policies to protect GCSB customers

GCSB Internet & Mobile Banking provide you with a private and secure environment to conduct banking transactions and communicate with our team. Only you and those you authorize on your enrollment form have access to your accounts or information.

Report a lost or stolen debit card

To protect your information and freeze a lost or stolen debit card, be sure to report the situation as soon as possible. During business hours (M-F 8:30 a.m. – 4:30 p.m. or Sat 8:30 a.m. – 12 p.m.), call your local GCSB branch. For after-hours reporting, call Shazam at (800) 383-8000.

Mobile & internet security features

Password Protection

Each time you log into your account, you are required to provide your username and password. For your security, please keep this information confidential. If you forget your password, contact Guthrie County State Bank. Your account will lock down after three incorrect attempts from your device.

Data Encryption

Each time you bank with the internet or mobile banking platform, your communications and log-in process will be encrypted. This allows your information to be scrambled when you send it to us, and we unscramble it upon receipt. This provides a high-level of protection of your data as it travels between us. To ensure your browser supports the required encryption, we recommend that you use a browser that supports 128-bit encryption.

Firewalls

Firewalls are a basic cyber security feature that play an essential role in who is allowed or not allowed to access the information it guards. The use of firewalls allows GCSB to prevent unauthorized or malicious attempts at accessing information.

Mobile-exclusive security measures

Operating System

Smartphones such as iPhones and Androids feature built-in operating systems that are highly controlled and secure. This alone plays an important role in protecting your mobile banking information.

Brella™ Fraud Alerts

Banking with the Brella™ app through GCSB gives you the ability to monitor suspicious activity through text alerts and app notifications on your mobile phone. Brella™ makes preventing fraud easy with capabilities to not only receive alerts, but to turn your debit card on or off as well.

Additional Security Authentication

To add another layer of protection to your information, your mobile banking account will require you to answer additional security questions for authentication when you first use your account.

Protecting Against a Lost Device

In the event that you lose your mobile device, it is important that you ensure nobody can access it or the information on it. Call your mobile service provider and follow the steps to deactivate your phone. Additionally, you can contact GCSB to remove your registered mobile device from your authorized account devices.
