Information regarding you (such as name, address and phone number) or your order and the products you purchase will not be given or sold to any outside organization for its use in marketing or solicitation without your consent. Your information may be shared with agents or contractors of Sierra Proto Express for the purpose of performing services for Sierra Proto Express.


Providing you with a secure online experience is a high priority for Sierra Proto Express. We recognize that your privacy and security are of the utmost importance, and we have devoted a great deal of effort to ensure that your personal information is safeguarded. Your transactions are supported by industry-standard data encryption.


Positive identification. The Sierra Proto Express website is registered with site identification authorities to enable your browser to confirm the Sierra Proto Express website’s identity before any transmission is sent. With this technology, (known as Certificate from Trusted Authority ), the identity of our site is automatically confirmed behind the scenes prior to the transmission of any customer information requested to complete an online order your data reaches your intended target or your browser notifies you (prior to your sending any personal information) that the potential receiving site looks suspicious and should be avoided.


If you are using a security-enabled browser (such as Microsoft Internet Explorer version 2.1 or greater, or Mozilla version 1.0.5 or greater), the information you send us regarding your purchase is encrypted, making it extremely difficult to read even if it is wrongly intercepted. The Sierra Proto Express website utilizes industry-standard Secure Sockets Layer (SSL) technology to allow for the encryption of potentially sensitive information such as your name, address and critically sensitive information like your credit card number.


If you use a security-enabled browser (such as Microsoft Internet Explorer version 2.1 or greater, or Mozilla version 1.0.5 or greater) paying attention to two browser features will decrease the chances for the unintended or fraudulent use of your personal information:

    Your browser security preference settings are your first line of defense to stopping the theft or unwanted viewing of confidential, personal information. The most popular browsers offer you the ability to receive an alert or notification if any of the following happen or are about to occur:

    • changing between secure and insecure transmission modes
    • receiving an invalid site identification for the site to which you are about to transmit
    • sending a transmission over an “open” or unsecured connection

    Check the settings of your browser security features to see all the checks that are possible and those that are currently in place.

    The presence of security measures surrounding the entry of data on a web page is identified in several ways for you on your browser:

    • A security symbol to indicate operation in a mode that supports secure transmissions
    • A “closed lock” icon is present in the bottom right-hand corner of your Microsoft Internet Explorer browser screen

    Security is a shared responsibility of Sierra Proto Express and users on our website, who have the capability to enhance the security of their own accounts:

    • Do not allow others to use your password
    • Select unique and non-obvious passwords which are different from your username
    • Change your password often
    • Log out when you’ve completed your purchasing session
    • Of course, this security is dependent upon users protecting their login information and access to their computer while logged in. The security of your company’s account is also increased by the fact that Sierra Proto Express tracks and records all purchasing and approval activity.

    We hope that once you understand the measures we employ and the steps you can take to protect yourself, you’ll be as confident about the security of your transactions and personal information as we are.
