Modern construction software rarely stands alone. The project management platform connects to accounting. Accounting connects to payroll and banking. Timekeeping apps feed payroll. Takeoff, estimating and scheduling tools exchange data with all of them, and a marketplace of add-ons promises to do even more. These integrations save time and reduce double entry. They also create access paths that are easy to overlook.
Each connected app may hold a token or key that gives it ongoing access to your data, often without a human logging in and without multi-factor authentication. If the app vendor is compromised, or if a former employee's personal trial app is still connected, that access remains. This article offers a simple way to review what is connected and decide what should stay.
Why integrations deserve attention
Integrations typically authenticate in one of three ways.
- OAuth connections. You approve an app to access your account with specific permissions. The connection continues until it is revoked.
- API keys or tokens. A long string, generated in one system and pasted into another, grants access. These are easily stored in insecure places.
- Service accounts. A dedicated login used by software, often with broad permissions and a password that never changes.
The risks are practical: too much access, forgotten connections, keys stored in spreadsheets or emails, and vendors with weak security of their own.
Step 1: Build an inventory
Start by listing every connected app. Look in each major platform for sections such as marketplace apps, connected applications, API settings, integrations or developer tools.
For each integration, record:
- The app name and vendor.
- Which system it connects to.
- What data it can read or write.
- Who set it up and who owns it now.
- When it was last used.
- How it authenticates and where the key is stored.
Ask department leaders, too. Project managers sometimes connect tools you will not find in IT records.
Step 2: Decide whether each integration is needed
Mark each as essential, useful or unknown. For unknown or unused apps, plan to disconnect them. Trial apps and abandoned pilots are common leftovers. Removing them reduces risk and sometimes saves license fees.
Step 3: Review permissions
For each remaining integration, ask what level of access it truly requires.
- Does it need to write data, or is read access enough?
- Does it need access to every project or only specific ones?
- Does it reach payroll or banking data that its function does not require?
Reduce permissions where the platform allows. If it does not, weigh the risk against the benefit.
Step 4: Evaluate the vendor
Before approving a new integration, a few questions go a long way.
- Where is our data stored and who can access it?
- How does the vendor protect customer data? Do they offer independent security reports, such as an audit report, when appropriate?
- How will we be notified if they experience a security incident?
- What happens to our data if we cancel?
- How are API keys protected and can we rotate them?
Small vendors may not have formal documentation. That does not automatically disqualify them, but it raises the stakes on limiting what they can touch.
Step 5: Protect keys and service accounts
- Store keys in a password manager or secrets vault, not in emails or shared spreadsheets.
- Give service accounts the minimum permissions needed.
- Use unique credentials for each integration.
- Rotate keys when staff leave or on a regular schedule.
- Monitor logs for unusual activity from integration accounts.
Step 6: Create an approval process
Prevent future sprawl by requiring a quick review before anyone connects a new app to company systems.
- A short request form with the business purpose and data involved.
- Review by IT or your provider and by the owner of the connected system.
- Documentation in the inventory.
- An annual review date.
Keep the process light so people use it, rather than bypassing it.
Include integrations in offboarding
When employees leave, check whether they created integrations tied to their personal accounts. A connection authorized by a departed user may break, or worse, continue under an account that has been repurposed.
A final thought
You do not need to remove every integration. The goal is knowing what is connected, making sure it is worth the access it holds, and having a way to cut it off quickly.
