HubSpot integration security review

Close the gaps in connected apps, webhook authentication, and single-owner integrations.

Three integration risks worth catching

Apps and AI connectors accumulate without an owner, hold live credentials, and bypass the permission model entirely.

Webhooks often reuse tenant-scoped credentials, so a compromised endpoint can be replayed against the whole account.

One architect owns every integration and automation, with no documented backup, so the knowledge leaves when they do.

Why do connected apps become a risk?

The review inventories every connected and private app, its scope, and when it was last used, so nothing live is invisible.
Dormant apps and over-scoped credentials are flagged for revocation or tightening to least privilege.
AI connectors are treated the same way: named, scoped and owned, rather than left to sit in the audit log unexplained.

Why do connected apps become a risk?

Why are webhooks a weak point?

Webhook authentication is checked so a dedicated token isolates the handshake rather than reusing account-wide scopes.
API keys are reviewed for rotation, so a leaked key does not stay valid indefinitely.
The aim is that a compromised endpoint cannot be replayed across the rest of the account.

Why is single-owner integration a problem?

The review maps who owns each integration and automation, and documents how each one works.
A backup owner and a written description are put in place, so deactivating one person does not break live flows.
The integration layer stops being a black box that only one person can safely touch.

Excellent migration and outcome

"We gave PYB some challenges in supporting the migration from Salesforce to HubSpot but they met them. There is deep knowledge in the team both of HubSpot and of links to other systems."

FAQs

How long does a HubSpot seat review take?

Usually 1 to 2 weeks. The first week pulls usage data and maps seats to people and roles. The second confirms reductions, sets up deprovisioning, and documents the right-sized licence position.

Can HubSpot show us real seat usage?

Yes. Login history, activity and seat assignment are all available. The review turns that into a clear picture of who uses what, so seat decisions rest on evidence rather than guesswork.

Does this affect our security posture?

Yes. Unused and orphaned seats are an access risk as well as a cost. Reclaiming them tightens the account and supports the access-control evidence an ISO 27001 review expects.

What HubSpot products does this apply to?

Any paid tier with assigned seats, and any account using marketing contacts. The review is most valuable where seat count has grown faster than the team, or where multiple hubs are in use.

Does HubSpot meet our security and accreditation requirements?

HubSpot holds SOC 2 Type II and ISO 27001. PYB adds its own ISO 27001, ISO 9001 and ISO 42001 certifications, plus the HubSpot Data Migration Accreditation, so the people configuring your access controls are themselves audited against the standards your buyers and regulators care about.
