Online Banking Security

The Nashua Bank, a division of Lake Sunapee Bank, understands that the security of your personal and account information is important to you. We also understand that our continued success as a financial institution relies on both our ability to offer banking services to you in a secure manner as well as your responsibility in keeping any access codes, passwords or PINs secure. To assist us in offering these web-based banking services in a secure manner, we employ a number of measures, which are described below. These measures allow us, among other benefits, to properly authenticate your identity when you access these services and protect your information as it traverses the Internet between your PC and The Nashua Bank*.

For more information on how you can be proactive in protecting yourself online, view our Online Banking Security Best Practices.

Log-In protection

You must privately maintain a combination of a Log-In ID and password. A password will be assigned to you for your first-time login. Upon that first login, you will be required to change to an absolutely private password. If your new password is lost or forgotten, contact our Customer Service Center at 866-614-3383 Monday – Friday from 9:00 am – 5:00 pm and Saturday 9:00 am – 12:00 pm to reset a default password once The Nashua Bank* has confirmed your identity.

You must safeguard your Online Banking Login ID and password by keeping them private and secure. Memorization is preferable, as any written password is vulnerable to theft. To reduce the likelihood of password guessing, you will be locked out from the Online Banking system after three (3) unsuccessful login attempts.

At that time, you can use the Self-Reset function (if activated), and be prompted to reset the password after answering personally set security questions.  You can also call our Customer Service Center at 866-614-3383 Monday – Friday from 9:00 am – 5:00 pm and Saturday 9:00 am – 12:00 pm for assistance.

The Nashua Bank* utilizes multifactor authentication when customers login to their accounts. Multifactor authentication is a method of verifying identity through a combination of secret or unique identifiers linked to a specific customer (such as passwords and other means).

To further protect you, a timeout feature is used. This feature will automatically log you out of your current financial service session after a 10-minute period of inactivity. You are responsible for preventing unauthorized viewing of or access to your computer during your online session.


Browser Security

The Nashua Bank* also requires the use of secure browsers to protect you while you access our online financial services. More specifically, the personal and account information that flows back and forth between your PC and The Nashua Bank* must be encrypted while in transit – secure browsers are how we achieve this level of protection. Encryption is the process of scrambling information (typically for data transmission) so that it can only be reassembled in its original clear text format by someone who has the correct encryption key to do so. When used between you and The Nashua Bank*, this technology encrypts your personal information as you send it to us, which only The Nashua Bank* can decrypt. Likewise, when we send personal or account information to you, this technology encrypts it, which only you can decrypt. This is possible through a certified 128 bit secure server by VeriSign so that no unauthorized individuals can read or decipher the data.

Our online banking service provider continually updates their list of recommended browsers. You can view the list here.


Our server does not connect directly to the Internet

It is isolated from the network via “firewall.” All requests to the server are filtered through a router and firewall before they are permitted access to the server. A router is a piece of hardware that works in conjunction with the firewall, a piece of software, to block and direct traffic coming to the server. The router and software “firewall” define and limit access that “outside” computers have to The Nashua Bank* server. The configuration begins by disallowing ALL traffic and then opens only when necessary to process acceptable data requests, such as sending customer requests.
