In the traditional approach to IT security, the “perimeter” meant the network boundary—inside the company was the trusted zone, outside was the threat zone. Today, that model is no longer adequate. In the era of cloud, hybrid work, SaaS, and APIs, the identity of the user, application, and device has become the new security boundary.
Why the shift in the security perimeter?
An article on TechTarget states:
“Identity has replaced network
boundaries as today’s security perimeter.”
– TechTarget, 2025
In turn, a Veza blog post says:
Identity is eating security—bite by bite, breach by breach… In the modern enterprise, identity has become both the battleground …”
– Veza, 2025
The data confirms it: in cloud and distributed environments, network boundaries lose their meaning—users and systems connect from many places, often outside the company’s traditional infrastructure.
Key challenges
- Non-human identity — devices, APIs, automations, bots. The growing dominance of “non-human identities” as a risk factor.
- Distributed infrastructure — cloud, SaaS, mobility, BYOD, partners; the traditional security perimeter is blurring.
- Growing identity-based threats — credential-based attacks, excessive privileges, orphaned accounts.
What does it mean for the organization?
Security must be identity-centric. This means shifting the question from “Where is the user and where are they connecting from?” to “Who are they, what can they do, and should they really have that access?” Implementing Identity Governance & Administration (IGA), access reviews, least-privilege principles, and a Zero Trust architecture is now the foundation of modern security.
How does sara.next fit into this model?
- Automated access reviews that support the principle of least privilege.
- A central dashboard for managing applications and roles, providing full visibility and control.
- Integration with directories, HR systems, and the cloud-identity management in hybrid environments.

Phase 1: IGA strategy and access mapping
Develop and implement an IGA strategy covering both human and non-human identities.
Phase 2: Implementing a Zero Trust architecture
Map access: who, what, when, and why. Use automated access reviews.
Phase 3: User education
Apply Zero Trust-every access request should be authenticated and monitored.
Phase 4: Automation and monitoring
Education: identity is the new security perimeter—user awareness is key to effective protection.
Traditional network boundaries are no longer enough. Today’s digital environment requires focusing on identity as the new security perimeter. Systems, applications, users, and devices connect from many locations. Identity-when managed properly-becomes the central control point for access. By implementing IGA solutions and a Zero Trust architecture, organizations can effectively adapt to the new security landscape.
