Cookie Notice

This Notice (defined below) is effective May 24, 2018.


Like most companies, Illumio uses automatic data collection tools such as cookies, web beacons, and other device identification technologies to operate our services and websites and to understand how you use them and what is useful to you, as well as for advertising purposes. This Cookie Notice (the "Notice") explains how we use cookies when: (a) you visit any of our websites that link to this Notice (such as or interact with any Illumio online advertising or marketing emails (the "Online Properties"); or (b) you use any of certain Illumio products and services deployed by your organization (collectively for the purposes of this Notice, the "Services")

Some cookies that we use at Illumio will collect personal information about you or information that becomes personal information if we combine it with other data. Any personal information that we collect will be used in accordance with our Privacy Policy.

When we talk about “Illumio,” “we,” “our,” or “us” in this Notice, we are referring to Illumio, Inc. and its subsidiaries.

What are cookies

Cookies are small files of letters and numbers that we store on your browser or the hard drive of your computer or other device. Cookies send data back to the originating website on each subsequent visit or share data with another website that recognizes that cookie. Unless you have adjusted your browser setting so that it will refuse cookies, our system will issue cookies as soon as you visit our websites or use our Online Properties and Services.

There are different types of cookies that vary by who sets them and how long they endure. For example, “first party cookies” are those that are set directly by Illumio, while cookies set on our behalf by advertisers and data analytics companies are known as "third party cookies.” Cookies also endure for different periods of time. “Session cookies” only last as long as your browser is open and are deleted automatically once you close your browser. "Persistent cookies" survive after your browser is closed, allowing for the recognition of your device when you open your browser and browse the Internet again.

Types of cookies we use

When you visit or interact with any of our Online Properties (such as our websites) or use our Services, we use first and third party cookies for a variety of purposes. Some cookies are required for technical reasons in order for our Online Properties and Services to operate, and we refer to these as "essential" cookies. Other cookies enable us: to track how our users and prospects use and interact with our Online Properties and Services; to enhance and tailor the experience on our Online Properties and Services; and to recognize your device and secure your access to our Services. We refer to these as “functional” cookies. We also use cookies to let us know how well our online advertising works, and to deliver more targeted online advertising and marketing campaigns. We call these “advertising” cookies. Some cookies also enable us to conduct analytics about online campaigns we are running and the usage and performance of some of our Online Properties and Services (what we call “analytical” cookies). Third parties may serve cookies through our Online Properties and Services for advertising, analytics and other purposes.

More information about the specific types of first and third party cookies served through our Online Properties and Services is available in the table below.

Cookie Type

Why We Use These Cookies

Who Sets Them


These cookies are strictly necessary to provide you with Services available through our Online Properties and to use some of its features, such as access to secure areas.



Although not essential, these cookies help us ensure we can continually make our Online Properties better by understanding how they are used, so that we can enhance and tailor our Online Properties for those who interact with them.

Illumio and third parties


These are used to understand, improve, and research our Online Properties and Services, including when you access any of our website and related websites from your computer or mobile device. In particular, we use web analytics tools to help us identify aspects of our Online Properties that may not be working as well as we would like them to, and to help us understand how our Online Properties are being used and how we can customize them for you.

Illumio and third parties


These cookies let us know how well our online advertising works, and allow us to deliver more targeted online advertising and marketing campaigns to you. We may also use these types of cookies to help us reach people who are more interested in our products. For example, we may read a cookie so we can serve you ads that may be interesting to you on other websites. We also use this information to retarget users with relevant advertising.

Illumio and third parties

Targeted advertising

Illumio has engaged one or more third party service providers to track and analyze both individualized usage and volume statistical information from interactions with our Online Properties. We also partner with one or more third parties (such as advertisers and ad networks) to display advertising on our Online Properties and to manage and serve advertising on other third party sites.

These third parties use cookies, web beacons, pixel tags, and similar tracking technologies to collect and use certain information about your online activities on our Online Properties and/or other third party sites. This information may be used alone or in combination with information about you we obtain from other sources (like our data partners), contact details, professional information and/or Illumio transaction history (as obtained from our customer relationship management database) to infer your interests and deliver you targeted advertisements and marketing that are more tailored to you based on your browsing activities and inferred interests (“Interest-Based Advertising”). Such Interest-Based Advertising will only be delivered where permitted by applicable law and in accordance with your advertising and marketing preferences.

Our third party service providers may also use cookies or web beacons to collect information about your visits to our Online Properties or other third party sites to measure and track the effectiveness of advertisements and our online marketing activities (for example, by collecting data on how many times you click on one of our advertisements).

The information collected through this process does not allow us or them to identify your name, contact details or other personal information that directly identifies you unless you choose to provide these.

Similar technologies

Cookies are not the only way to recognize or track users of our Online Properties and Services. We may use other similar technologies from time to time, like web beacons (sometimes called "tracking pixels" or "clear gifs") to track users of our Online Properties and Services. These are tiny graphic files that contain a unique identifier that enable us to recognize when someone has interacted with our Online Properties, Services, or e-mail. This allows us, for example, to monitor the traffic patterns of users within our Online Properties and Services, to deliver or communicate with cookies, to understand whether you have come to our Online Properties and Services from an online advertisement displayed on a third-party website, to improve our Online Properties, and Services, and to measure the success of e-mail marketing campaigns. In many instances, these technologies are reliant on cookies to function properly, so declining cookies will impair their functioning.

Most web browsers allow you to manage cookies in a way that suits your preferences. In some browsers, you can choose to accept or reject all cookies, or manage them on a site-by-site or type of cookie basis, giving you more control over your privacy.

Most advertising networks offer you a way to opt out of Interest-Based Advertising. If you would like to find out more information, please visit or

You can opt out of having your mobile advertising identifiers used for certain types of Interest-Based Advertising, including those performed by us, by accessing the settings in your Apple or Android mobile device and following the most recent published instructions. If you opt out, we will remove all data about you and no further data collection or tracking will occur. The random ID we or our third party partners had previously assigned to you will also be removed. This means that if at a later stage, you decide to opt in, we will not be able to continue to track you using the same ID as before and you will for all practical purposes be a new user to our system.
