Security Statement


Mercantile Bank has purchased an Extended Validation (EV) SSL Certificate for the website, which provides an additional layer of protection. This enables customers to trust that the Mercantile Bank site is what it claims to be, rather than a fraudulent mirror site operated by perpetrators of phishing schemes. This is new technology designed specifically to address widespread phishing schemes that have been targeting the financial services industry.

When you visit a site with this new EV SSL Certificate, new high-security browsers will trigger the address bar to turn green and display the name of the organization listed in the certificate as well as the Certificate Authority.

Internet Banking System

This Internet Banking System brings together a combination of industry-approved security technologies to protect data for the bank and for you, our customer. It features password-controlled system entry, a VeriSign-issued Digital ID from the bank's server, Secure Sockets Layer (SSL) protocol for data encryption, Multifactor Authentication Technologies, and a router loaded with a firewall to regulate the inflow and outflow of server traffic.

Secure Access and Verifying User Authenticity

To begin a session with the bank's server the user must key in a Log-in ID and a password. Our system, the Internet Banking System, uses a "three strikes and you're out" lock-out mechanism to deter users from repeated failed login attempts. After three unsuccessful login attempts, the system locks the user out, requiring a phone call to the bank to unlock the account before re-entry into the system. Upon successful login, the Digital ID from VeriSign, the experts in digital identification certificates, authenticates the user's identity and establishes a secure session with that visitor.

Multifactor Authentication

Mercantile Bank has instituted additional technologies to help protect you against multiple forms of fraud. Upon your initial login into the online banking or mobile systems you will be presented a Temporary Access Code (TAC). The TAC can be received as a phone call or text. For convenience, you are offered the ability to register any and as many devices as you desire. After which we will recognize your device and you will no longer be required to enter a TAC upon subsequent logins on those devices. However, if you desire added security, refrain from registering any device to continue to receive a TAC upon subsequent logins. Note: On our website, Mercantile Bank will never ask you for your, Social Security Number, Credit, Debit or ATM Card numbers or your PIN.

Secure Data Transfer

Once the server session is established, the user and the server are in a secured environment. Because the server has been certified as a 128-bit secure server by VeriSign, data traveling between the user and the server is encrypted with Secure Sockets Layer (SSL) protocol. With SSL, data that travels between the bank and customer is encrypted and can only be decrypted with the public and private key pair. In short, the bank's server issues a public key to the end user's browser and creates a temporary private key. These two keys are the only combination possible for that session. When the session is complete, the keys expire and the whole process starts over when a new end user makes a server session.

Router and Firewall

Requests must filter through a router and firewall before they are permitted to reach the server. A router, a piece of hardware, works in conjunction with the firewall, a piece of software, to block and direct traffic coming to the server. The configuration begins by disallowing ALL traffic and then opens holes only when necessary to process acceptable data requests, such as retrieving web pages or sending customer requests to the bank.

Using the above technologies, your Internet banking transactions are secure.

Policy Changes and Website Maintenance

As our business grows and changes, and as technology and Internet use and practices change, the Bank may, from time to time, determine that changes in its policies, including the Internet Privacy Statement and Security Statement, are prudent. If any such changes are made, they will be posted on this website. Therefore you should review the Mercantile Internet Privacy Statement, Security Statement and other policies posted on this site for potential changes when you return to the site for future visits.

Mercantile Bank is strongly committed to our relationship with you. We want to help you protect yourself and your accounts from fraudulent methods to gain access to your information.

If you have any questions or concerns, please do not hesitate to contact us.
