We are committed to the highest degree of respect for the privacy of our users, visitors to our websites and attendees of our events. In this Privacy Statement, we use “we,” “us” or “our” to refer to ISC and “you” or “your” to refer to you, the user, subscriber or visitor to our web sites. For certain purposes of this Privacy Statement, we distinguish between individuals who choose to subscribe and participate on our user mailing lists, fora, or our open code collaboration sites (“Subscribers”) and users of our websites (the “Sites”) who simply visit the Sites (“Visitors”) and do not choose to register as Subscribers. Unless indicated otherwise, all provisions of this Privacy Statement apply to Visitors and Subscribers. This Privacy Statement applies to all of our Sites.

By accessing and using any of the Sites as a Visitor, you expressly and knowingly consent to the information collection and use practices as described in this Privacy Statement.

Our commitment to your privacy is based on the following principles which we apply to our use of both your personally identifiable data (“Personal Data”) and to certain anonymous information we collect when you visit our Sites (“Technical Information,” and together with Personal Data, “Your Data”):

  • We will describe Your Data which we collect;
  • We will inform you clearly about our collection and use of Your Data;
  • We will not sell or rent Your Personal Data to others;
  • We will endeavor to be completely transparent and open about our data privacy policies and practices.

How Do We Collect Information?

We collect Your Data in the following basic ways:

  • You give it to us in email inquiries or in your public comments on our mailing lists or social media sites;
  • We automatically collect Technical Information when you visit our Sites;

This may include name, title, company/organization name, postal address, email address, work, home and mobile phone numbers, plus other relevant information you provide. See our Frequently Asked Questions (FAQ) list for specific data elements we may request and collect.

This information includes – how many visits we have to the Sites, when those Sites are visited, browser types used for Site visits, name of the Internet service providers, the Internet Protocol (IP) address through which you access the Internet, pages that you access while at one of the Sites, Software you downloaded from any of the Sites, How you found the Site (e.g. via search, Google Ads or referral from another web site), and the Internet address of the website from which you linked directly to one of the Sites.

  • We do not sell or rent any Personal Data supplied by you.
  • We work with other companies, consultants, and contractors to provide services on our behalf, such as Site and service hosting, survey hosting, audio and video conferencing, public relations, order processing and fulfillment, and mailing, sending information including but not limited to our software, services, and events. We will provide those companies only the Personal Data they need to perform the service for which they are retained and they agree to treat information confidentially and to only use it for the purposes of providing services under our agreement with them.
  • We may use Your Data to provide you with more effective customer service and to improve the Sites and any related products or services we may provide or make available.

We do typically contact you and ask how you would like to be identified, but in some cases your information will appear automatically (e.g. in a commit lot or issue tracker).
  • We may use Technical Information to periodically analyze Site logs to assess aggregate usage trends in order to better serve the needs of Visitors and Subscribers and maximize the user viewing experience.

Can I Choose Not to Receive Commercial Email Communications?

We use unsolicited bulk email for marketing purposes very infrequently because we are aware of the problems and annoyance caused by spam email. Every bulk email we send to you contains an easily discoverable link that will allow you to unsubscribe and stop all subsequent unsolicited commercial or marketing messages from ISC delivered via our marketing mailing list. Unless you subsequently consent (opt in) to the receipt of commercial or marketing emails, we will not use your email address for such purposes. Please note that the public mailing lists for open source support and discussion do occasionally include messages that may be construed as “marketing,” but those lists are not primarily maintained for marketing purposes, and you will never get email via those lists unless you explicitly subscribed. If you need help in unsubscribing from any ISC mailing list, please email our sales team at

Subscribers to our mailing lists will receive email from us with information about us, upcoming events, or issues related to the Internet, as well as posts by other Subscribers. Subscribers to updates from our various collaboration sites, including Github,, and others will also receive updates to issues they create or subscribe to.

We do not engage in targeted marketing activities including but not limited to device finger printing, profiling, and/or cross-device tracking.

Credit Card Information

Credit card information is not collected or stored on our servers. When you conduct transactions through a Site, payment and payment card information for transactions with us is entered directly into a third-party processor’s systems and is not transmitted through or stored by us. The card processor provides us with an authorization code which is securely stored with the payment record on our servers. In rare cases, when you explicitly request that we directly process a credit card transaction on your behalf, and you personally transmit that information to an ISC employee, we may enter it into a third-party system for you with your explicit consent.

Use of Cookies; Technical Information Collection

Our Sites use third parties for web analytics services to collect Technical Information. See our FAQ for a current listing of such third parties. These third parties do or may use “cookies” or similar technologies, which are text files placed on your computer, to help analyze how you use a Site. The information generated by the cookie about your use of a Site (including your IP address) will be transmitted to and stored by these service providers’ servers. They will use this information for the purpose of evaluating your use of a Site, compiling reports on website activity for website operators, and providing other services relating to website activity and Internet usage. They may also transfer this information to third parties where required to do so by law, or where such third parties process the information on their behalf. You may refuse and block the use of all of our (and third-party) cookies by selecting the appropriate settings on your browser.

Data Security

We take reasonable and appropriate measures designed to protect the security of data transmitted to us upon receipt. ISC is a strong advocate of privacy-enhancing technologies. By default, the Sites encrypt connections between client devices and our servers to minimize the ability of any third party to “eavesdrop” on Your Data.

Our DNS entries are signed using DNSSEC, so that if you use a DNS resolver that validates DNSSEC signatures, you can be assured that the site you are reaching is in fact published by ISC.

Our databases and system administration logs are restricted to access by authorized and authenticated users.

Our servers or offices may be located in countries other than the country from which you access our Sites, also resulting in the transfer of Your Data across international borders. If you provide Your Data when visiting one of our Sites from outside of the United States, you acknowledge and agree that this data may be transferred from your then-current location to our offices and servers and to those of our affiliates, agents, and service providers located in the United States and in other countries.

Our collection and use of any of Your Data is subject to the laws and regulations of the countries and political subdivisions in which our Visitors and Subscribers reside.

Control of Your Personal Information (“Do Not Track” Notice)

We respect enhanced user-privacy control and support the development and implementation of a standard “Do Not Track” (DNT) browser feature, designed to provide users universal and persistent control over the collection, sharing, and use of information by third parties regarding their web-browsing activities. Once the specification is finalized we intend to honor users’ requests with respect to browser tracking.
