SOLUTIONS / SAAS

Your customers share a product.
Their data should stay separate.

Roles, tenants, integrations, and exports multiply as a SaaS product grows. Galen helps teams find supported access weaknesses and catch changes that widen exposure beyond the rules they approved.

Available now: Galen Policy Beta and Managed Galen Security Audits. Self-service Galen Security is coming soon.

INTENDED BOUNDARY

Every report lookup must be constrained to the caller’s tenant.

The issue to investigate

The new download route loads a report by ID without a tenant restriction.

The caller-to-report path lacks the tenant boundary on the selected record.

Conceptual example, not live Galen output. Recheck the actual implementation after a correction.

WHAT IS AT STAKE

One useful feature can create a new path across tenants.

A SaaS application can enforce tenant isolation in its main screen and lose it in a background export, an administrative route, or a newly generated API. A signed-in user may reach an endpoint that accepts a record ID without checking which customer owns it.

Growth adds more boundaries: support access, custom roles, delegated administration, integrations, and shared links. Those rules need to survive refactors and new features. Galen connects the code behind the operation and helps your team preserve approved access behavior as the product evolves.

Tenant trust
Inspect the backend boundary around customer records.
Role clarity
Keep member, admin, and support authority distinct.
Product change
Catch new grants and broader responses early.

CHECK WHILE YOU BUILD

Keep tenant rules through the next feature.

Galen Policy checks supported code for security weaknesses while developers build. It also recovers access behavior for the team to review and approve, then compares later changes with that baseline.

Use it when a serializer adds fields, a new endpoint writes customer data, or a role helper changes. The relevant finding gives the developer or coding agent a concrete boundary to restore. An intentional new permission can be reviewed and approved explicitly.

GO DEEPER WITH AN AUDIT

Look beyond the route your interface normally uses.

Galen Security supports deeper review of application and API paths, including the controls around sensitive reads, writes, and responses. The evidence helps explain how a less visible route can bypass the restriction users see in the interface.

Scope a review around tenant isolation, a new integration, or a major release. Ask Telhawk to lead a Managed Security Audit and recheck submitted corrections. Self-service Galen Security is coming soon.

WHERE TO FOCUS

Follow the boundary through the growing product.

Boundary or decisionWhat needs attentionEvidence to inspect
Tenant recordsA helper scopes one route correctly but another route omits the constraint.The selected object, relevant paths, and tenant controls.
Custom rolesA convenience check admits a member to an admin action.The actor, privileged operation, and governing role guard.
Bulk responsesAn export includes fields or records outside the intended customer scope.The response construction and approved access boundary.

A PRACTICAL STARTING POINT

Treat isolation as a rule that survives change.

  1. 01

    Review current access.

    Identify important tenants, roles, records, and private fields.

  2. 02

    Approve the intended baseline.

    Resolve unsafe existing behavior before making it the rule.

  3. 03

    Check each relevant change.

    Use Policy in development and a deeper audit for broader release questions.

BUILD WITH BETTER EVIDENCE

Grow the product without quietly widening access.

Start with Galen Policy in development and use Galen Security for a deeper view of the application’s boundaries.
