Secure Third-Party and Vendor Access

The Challenge

Why Supplier Access Is a Risk

Suppliers, contractors and partners often need access to your systems. Without controls, that access is broad, permanent and unseen.

Permanent Access

Supplier accounts stay active long after the work ends.

Broad Permissions

Third parties get more access than the task requires.

No Oversight

Nobody watches what external users do.

Unsafe Connections

VPN or remote tools opened directly into the network.

FAQs

Frequently Asked Questions

Common questions about this use case.

How do we know third-party access needs tightening?

Supplier accounts without end dates, shared contractor logins and open remote access tools are the usual warning signs.

Will controls slow down our suppliers?

Access is requested and approved through a simple workflow, so suppliers get what they need quickly, for as long as they need it.

What information is needed to get started?

A list of suppliers with access, the systems involved, how access is granted today and who sponsors each supplier.

Which environments does this apply to?

Cloud and on-premises applications and directories, for employees, contractors and suppliers.

How is progress measured?

Agree a baseline for measures such as third-Party accounts, accounts with expiry, monitored sessions and review completion, then track them over time.
