External Identity and Access Management Solutions

Don’t set your business relationship status to ‘it’s complicated’ – empower your partners to get the job done.

An external identity and access management solution secures collaboration with users outside your organisation.

Businesses rely on an everchanging network of partners across the supply chain. To keep pace with dramatic shifts in the business landscape, these external users need to access corporate resources and interact with your workforce now – nobody wants to wait until tomorrow.

But how do you provide rapid access to data and applications across a complicated partner ecosystem without cutting corners and risking a security breach?

73% of enterprises experienced an increase in third-party risks amongst their partners and suppliers after transitioning to remote working.

A complicated B2B digital relationship

You need to collaborate with multiple organisations and individuals beyond the boundaries of your business.

Your challenges:


Partner entitlements overextended with inadequate policies and access controls.


No sight of partner account life cycles, as users leave, and credentials are shared.


Managing the partner identity lifecycle adds complexity and increased liability.

User friction

Password fatigue with users forced to use different credentials across apps and portals.


Administrative overheads to create and manage partner identities and credentials.


Takes too long to onboard users and provide access to required data and applications.

We have engaged with ThirdSpace on a number of key projects in the IAM space. They have greatly increased the pace at which we’ve been able to adopt new technologies, both in terms of deployment and business transformation services.
