How secure is using the Outlook add-in in HubSpot for privacy?

GTan — Fri, 24 Oct 2025 16:15:28 GMT

How is our data handled or shared when using the Outlook add-in in HubSpot?

Hi, is there any way that we can use the outlook addon without putting in your email and password ?

How safe and privacy does Hubspot is if there is data breach ?

How does our data being used by third parties vendors ?

Hi @GTan!

Are you referring to the Outlook 365 Data Sync integration, as listed in the App Marketplace? If so, then you can rest assured that HubSpot does not have access to your Outlook password or other private credentials. HubSpot just securely get the permissions to your access and update your Outlook contacts.

To connect your account to HubSpot we're using Microsoft Entra ID (formerly Azure Active Directory) which is Microsoft’s cloud-based identity and access management service.

Since you talk about an "add-on", I fear you may be talking about some other Outlook extension. If so, you will probably need to ask this in another part of the community.

Hope this clarifies!

So the outlook add-on is having you log into outlook. HubSpot is not using or storing your login. You are just connecting the two apps just like you do when you log into outlook on your phone and allow your phone to send and receive emails. You have control over this sending and receiving from HubSpot.

HubSpot is used by over 100,000 companies worldwide. Their security is SOC 2 certified. That is the same level that healthcare is required to have.
You can read more about security here: "Security, Privacy, and Control"

HubSpot does not sell your data. Only you have access to your metadata. HubSpot only showcases the larger numbers that it can see; i.e. email sends, number of users, etc. None of your personal data is sold to third parties.

Hi @GTan,

It's not possible to use the HubSpot Sales extensions without logging in – HubSpot needs some way to associate a user with a HubSpot portal.

That being said, you can learn about HubSpot's security measures here: "HubSpot Trust Center".

Hope this helps!

Hi, I have been to the page suggested here: "Security, Privacy, and Control"
and I am trying to download the Penetration Test Report. I put in my name, email and agree to the terms, but the report isn't coming through.

The HubSpot web chat sent me here.

Please can you advise on how I an download the report?

Many thanks

I have solved this issue. A pop-up blocker was preventing the download pop-up from being visible in Safari. Swapped to Chrome, disabled the pop-up blocker and downloaded the report.
