"Once we could actually see what data was sitting where across our planning boards, we stopped treating every vendor like they had clearance to see everything. The knowledge layer made the invisible visible.", director of operations at a mid-size corporate retreat planning agency.
Many planning organizations treat their project management tool as a single workspace for their team. As a result, information about attendees with personally identifiable information is exposed to individuals who should not see it.
What attendee PII exposure in project boards actually means for travel and retreat agencies
When we talk about attendee personally identifiable information (PII), many planners automatically think of a name and email address in relation to a corporate retreat project. However, PII can encompass a lot more information than that of an attendee to a meeting or event. PII for a single corporate retreat project could include items such as a guest’s passport number, a 3 digit code for their dietary restrictions, a guest’s disability and their requested accommodations, a guest’s emergency contacts, information about who is sharing a room with whom for their events, and information for direct billing to the company of each of the travelers for their meetings and events. All of this information is personally identifiable information or PII for short. And, as many of these pieces of information are sensitive in nature, they will fall under the scope of several data privacy regulations including the GDPR and the CCPA.
The exposure problem is deep rooted. Most project management tools such as Asana, Monday.com, ClickUp and Notion are by nature collaboration tools for projects. Hence, they are open by design. This means when a new project coordinator joins a team, he or she is given access to the entire existing workspace including all previous projects, tasks, attachments and comments from past events dating back two years. None of this access was granted intentionally. It just happens.
From there it snowballs very quickly. One agency is running 6 different retreats and 6 different project boards, each project board filled with the relevant traveler information and then shared with the relevant subset of staff, freelance project coordinators at the hotels and relevant transport vendors. It becomes very difficult for anyone to have a clear picture of the PII surface and where all that PII resides.
How attendee PII ends up scattered across shared project workspaces
The path is predictable once you trace it.
A client has registered for the event and I have added their details to the spreadsheet which is attached to the relevant project task. I have copied in relevant dietary requirements to the catering brief which I have then pasted into the relevant slack channel. The travel coordinator has uploaded in the passport scans to the shared Google Drive folder which links from the board. Third-party ground transport vendor has been added as a guest user so they can see the transfer times. Also they can see the passport folder as it lives in the same Drive as the board.
According to IBM's 2024 Cost of a Data Breach Report, 40% of breaches involved data stored across multiple environments, and more than one-third involved shadow data, defined as data stored in unmanaged sources. For a retreat agency the term “shadow data” might be the dietary spreadsheet that was in an old task attachment somewhere that you never went back to delete it all, or the list of emergency contacts for the participants that were only sent as part of a catering email and never looked at again.
The vast majority of the PII problems one reads about on the internet today are not the result of someone’s malicious intent. PII is inherently a component of any given project that is going through a lifecycle. The tools that are currently employed by the US Government to thwart the PII movement are largely inadequate to halt the PII movement as the project transitions through the lifecycle of development and deployment.
Where the real access control gaps are in agency project boards
There are three places the gaps tend to be worst.
Guest and vendor access. Most of the project management tools allow adding guests and vendors to a project. What seems to be a simple action of adding a guest / vendor to a project actually results in such external person being able to read all sections of the board (including those already closed and information on past events) whereas the core project team member would not be able to access that same information. The permission model says "project access." The actual exposure is much wider.
Task attachments and linked cloud files. These are outside of the permission structure of your project management tool. A file shared from Google Drive keeps its own access rules, which usually default to "anyone with the link can view." Once that link is pasted into a task comment, it is effectively public within the workspace, and often well beyond it.
Summary: There is a huge gap between theoretical access control in project management tools and the real access control in project management.
How to audit who can see attendee PII in your project management tools
An access audit for projects is not a purely technical exercise. For every active project ask the simple question: Who has access to the project board and what can they see.
Walk through these steps on a monthly basis.
-
Export the user list from every active workspace. Most project tools have an admin panel that shows this. Pull every user, including guests and external collaborators, and note their permission level.
-
Map the PII fields. List every field in your registration forms and note which ones collect PII. Passport numbers, legal names, phone numbers, accommodation preferences tied to individuals, payment references. Then trace where that data lands after collection. Spreadsheet? Task attachment? Slack message? Each destination is an exposure point.
-
Check linked file permissions. For every Google Drive or SharePoint folder linked from a project board, open the sharing settings. Look for "anyone with the link" permissions and replace them with named-user access.
-
Review vendor and freelancer accounts. Cross-reference your project tool's user list against your current active contractor roster. Deactivate any account that does not belong to someone currently working an open event.
-
Document what you find. A simple spreadsheet logging each project, its collaborators, the PII types present, and the last access review date is enough to start. You are building a paper trail, not a compliance system.
It doesn’t have to be perfect the first time it gets done. Getting something done once and then doing it every month is far more important than getting it perfect the first time.
What good PII access control looks like for a retreat planning agency
An effective access control mechanism has three fundamental characteristics: 1) intentional (i.e., no default access granted to anyone), 2) current (i.e., most recently checked for relevant individuals and refreshed on a monthly basis), and 3) scoped (i.e., a vendor responsible for transfer logistics for example would not have access to see passport information).
Even when data resides across different platforms (e.g., project management board, Drive folder, Slack channel, registration platform, all highly interconnected), tracking and managing key metadata such as accuracy, timeliness, and source information (i.e., data provenance) is time-consuming and agencies lack critical awareness of the information they possess, where it resides, and who uses it for what purposes.
LemonLime is a solution to the exact problem Planning & Operations focused businesses on a stack of tools face. For travel and retreat agencies running on Google Workspace: Slack, HubSpot and Microsoft 365 among other tools, LemonLime builds a single layer of knowledge on top of the tools you already have, that AI can then query and reason off of. No data migration required. No engineering setup required. The layer gets smarter the more you use it. The more you use it, the sharper a picture it gives you of the data you have, and where it is.
For an agency trying to answer "who can see this attendee's passport number right now," that kind of organized, AI-readable knowledge layer changes the question from a manual archaeology project into something you can actually answer quickly.
Security and compliance specifics, including how LemonLime handles data in practice, are detailed at lemonlime.ai/security. Review that page against your own needs before you hook up that tool that holds PII.
Instead of introducing more new policy and rules it is more practical to clarify the current situation. Start the monthly access audit this week, and then look at lemonlime.ai to see how a knowledge layer makes that visibility sustainable.
Frequently Asked Questions
Why does my project board give vendors access to attendee data I didn't mean to share?
The default way that most project management tools grant access to guest users is at the workspace/ project level and not on a task by task basis. Therefore the example vendor brought in to look at transport logistics would have read access to all the attachments and linked files on the project including the registration data that they had not been intended to see. By explicitly reviewing guest permissions as opposed to just going with the default settings for guest users these problems can be solved. LemonLime surfaces the data that agencies have set up across the connected tools that they use and therefore reveals the problems that they had not even known existed before.
What counts as attendee PII in a corporate retreat planning context?
PII (Personal Identifiable Information) is highly categorized with many different data points listed. To start with, there are full names (full legal names), email addresses, phone numbers. Then there are passport numbers and national ID numbers, as well as dietary needs and health issues of individuals. Also, where are you staying? Who are you sharing a room with? A list of a traveler’s emergency contacts and any payment or billing information that is tied to a specific named traveler. There is also sensitive PII (Personal Identifiable Information) under the GDPR and/or CCPA regulations. This includes health information, for example. Start listing of this data on your registration form and then moving on from there.
How often should my agency audit who has access to attendee data in our tools?
For an agency that is running multiple events at the same time, the default cycle of ‘Monthly’ can be very effective for managing all of the projects in a timely fashion. The greatest risk of mismanaged user accounts would likely be shortly after an event has concluded, as accounts for vendors as well as agency use of freelancers would need to be disabled as other projects start to come online. A simple list of current users in a spreadsheet for completed projects would allow for easy review at the end of the month for outstanding accounts, without needing to bring the agency’s IT process into play for what would likely be a rare occurrence of recurring issues.
What should I do if I find attendee PII in a shared project board that shouldn't be there?
Revoke access of non-core team members. Move/Remove data from the task or comment where the data leak occurred and store the data in one place with explicit named-user permissions. If the data leak involved information of individuals subject to the GDPR or CCPA then document the leak (what, how long, who). Whether or not such an incident is reportable is outside of your control and best to get confirmation from legal counsel as it is outside of your control.
Is it safe to use tools like Slack and Google Drive for attendee data at all?
So called “insecure” tools have default settings which are open by design, and therefore need to be configured to be more restricted by default. Slack channel permissions, Google Drive link sharing, and project board guest access all need to be locked down by someone on an regular basis, and it is dangerous to assume that these tools are “safe” by default as they are not. For how LemonLime handles data from these connected tools, see lemonlime.ai/security.
My agency is small. Do I really need to worry about this, or is this an enterprise concern?
Just because your organization is small does not mean that you handle less categories of PII or less PII. A boutique organization that hosts 10 retreats a year and has 100-200 travelers at each retreat collecting passport numbers and health information for example is dealing with the same types of information that a larger organization would deal with. And just because your organization is small does not mean that regulators grant you a size exemption from compliance with GDPR or from compliance with CCPA. The practical exposure from a vendor that is in your workspace for longer than necessary or a Drive folder that was shared with too many people is probably greater in a small organization where access was granted on an ad-hoc basis.

Frequently Asked Questions
Why does adding a vendor to my project board give them access to attendee passport scans they shouldn't see?
Most project management tools like Asana, Monday.com, and ClickUp grant guest access at the workspace or project level, not task by task. So a ground transport vendor added for transfer logistics can read every attachment and linked file on the board, including passport folders stored in connected Google Drive. Reviewing guest permissions explicitly, rather than accepting defaults, closes this gap. LemonLime surfaces exactly this kind of unintended exposure across your connected tools.
How do I audit who can actually see attendee PII across my agency's project boards right now?
Start by exporting the user list from every active workspace, including guest and freelancer accounts, then map where PII fields land after collection: spreadsheets, task attachments, Slack messages, linked Drive folders. Check sharing settings on every linked file for 'anyone with the link' permissions and replace them with named-user access. Doing this monthly matters more than doing it perfectly once. LemonLime makes this ongoing visibility sustainable by organizing your data across connected tools into a single AI-readable knowledge layer.
What types of attendee information from my retreat registration forms actually count as PII under GDPR or CCPA?
More than you might expect. Beyond names and emails, PII in a retreat context includes passport numbers, dietary restrictions tied to health conditions, disability accommodations, room-sharing assignments, emergency contacts, and billing information linked to a named traveler. Health-related data like dietary needs or medical accommodations qualifies as sensitive PII under both GDPR and CCPA, carrying stricter obligations. LemonLime helps you trace where each of these data types ends up across your existing tools after collection.
My retreat planning agency only runs about 10 events a year — is attendee PII exposure still a real risk for me?
Yes. Event volume doesn't reduce your regulatory exposure. A boutique agency collecting passport numbers and health information from 100 attendees per retreat handles the same categories of sensitive PII as a large enterprise, with no size exemption under GDPR or CCPA. Smaller teams often grant tool access on an ad hoc basis, which makes unintended exposure more likely, not less. LemonLime is built specifically for planning and operations teams on tools like Google Workspace, Slack, and HubSpot, regardless of company size.
