TL;DR: SaaS data sharing is creating persistent exposure through inactive external shares, personal email access, and dormant third-party integrations, according to Valence Security’s 2025 survey findings. The governance problem is no longer collaboration itself but the lack of visibility, expiry, and revocation discipline across SaaS data paths.
Editorial analysis by NHI Mgmt Group, based on content published by Valence Security: “Taming the Wild West of SaaS Data Sharing”.
By the numbers:
- 94% of external data shares in SaaS applications were inactive, according to Valence Security.
- 46% were shared to personal email accounts, according to Valence Security.
- 58% of organisations experienced at least one SaaS-related security incident in the past year, according to Valence Security.
Key questions
Q: What breaks when SaaS permissions are too broad or poorly managed?
A: Poor permission hygiene can expose large volumes of sensitive data through public links, overprivileged accounts, unrestricted external sharing, and forgotten contractor access.
Q: Why do inactive external shares and dormant integrations create so much risk?
A: Because they behave like unmanaged entitlements.
Q: Why do SaaS sharing controls fail so often?
A: They fail because many organisations rely on policy, not enforcement.
Practitioner guidance
- Map all external sharing paths Inventory links, folders, email-based sharing, and connected app permissions across the SaaS estate so security can see where data can leave controlled identity boundaries.
- Enforce automatic revocation and expiry Apply time-bound access for external shares and integrations, with policy-driven removal when business need ends or ownership changes.
- Block personal-domain distribution Prevent sharing to personal email accounts unless there is a documented exception and a compensating control for monitoring and revocation.
Bottom line: SaaS sharing sprawl is not just a collaboration issue. It creates durable access paths that can outlive the business need that originally justified them.

Shared-data sprawl has become a governance problem, not a collaboration feature problem. The core issue is that SaaS access paths are created faster than they are retired, reviewed, or right-sized. That turns routine sharing into persistent entitlement growth across the business. Security teams should treat every new sharing method as an access lifecycle event, not a convenience setting.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 1 in 3 organisations encountered suspicious AI agent activity in 2025, and 99.4% experienced a SaaS or AI ecosystem incident.
A question worth separating out:
Q: Should organisations compare open-link sharing with personal email sharing?
A: They are different failure modes, but both bypass normal enterprise governance. Open links weaken recipient authentication, while personal email moves data outside managed identity and device controls. The better question is which paths can be centrally monitored, revoked, and time-limited, and which cannot.
