Identity becomes the new perimeter of cybersecurity
Hybrid working, SaaS and the cloud are shifting security from the network towards the digital identity of every user and service.
News summary
For years, the cybersecurity strategy of many companies relied on a simple idea: robust protection of the corporate network. However, the expansion of hybrid working, SaaS applications and cloud environments has completely changed the landscape. Today, a user can access critical data from different locations, devices and applications; therefore, identity has become one of the primary control points.
This evolution is accelerating the adoption of measures such as phishing-resistant MFA, conditional access and continuous permission reviews. It is no longer enough to verify a password at login. Organisations need to assess the context: which device the user is connecting from, which resource they are requesting, whether the behaviour is typical, and what level of privileges they are assigned.
The shift also affects technical accounts and machine identities. Automations, APIs, containers and cloud services handle credentials that can become an entry point if they are not correctly rotated, limited and monitored. Consequently, a modern identity policy must encompass both people and workloads.
For SMEs, this approach does not necessarily involve deploying a complex architecture. A good starting point is centralising identities, removing obsolete accounts, applying least privilege and protecting high-risk access with additional controls. These improvements typically offer an immediate impact and reduce a large proportion of incidents linked to credential theft.
A simple indicator to know if the strategy is working is to observe how many accounts still rely solely on a password and how many privileged accesses remain permanently active. Reducing these two figures provides a tangible benchmark for improvement. It is also advisable to review joiners, movers and leavers quarterly to prevent permissions from accumulating over time.
What happened
Hybrid work, SaaS applications and cloud environments have changed the security model of many businesses. Properly protecting the corporate network is no longer enough when a user can access critical data from different locations, devices and applications; that is why identity has become one of the main control points.
This shift is driving adoption of phishing-resistant multi-factor authentication, conditional access and continuous permission review. Verifying a password at login is no longer sufficient: the context of each access needs to be assessed.
What it means for a mid-sized business
The change also affects technical and machine accounts: automations, APIs, containers and cloud services handle credentials that can become an entry point if not rotated, restricted and monitored. A modern identity policy must cover both people and workloads.
For an SME, this does not require a complex architecture. Centralising identities, removing obsolete accounts, applying least privilege and protecting the highest-risk access points with additional controls usually delivers an immediate impact and cuts a large share of credential-theft incidents.
What to review
Practical indicators to assess the maturity of identity management:
- How many accounts rely on a password alone, without a second factor.
- How many privileged accesses remain permanently active instead of being granted only when needed.
- Whether joiners, leavers and role changes are reviewed quarterly to prevent permission creep.
- Whether technical and service accounts rotate credentials and have permissions limited to what is strictly necessary.
Frequently Asked Questions
- What does it mean that identity is the new perimeter?
- That access control no longer depends only on being inside the corporate network, but on verifying who the user is, where they connect from and in what context.
- Is enabling two-factor authentication enough?
- It is a fundamental step, but it should be combined with least privilege, periodic permission reviews and control of technical accounts.
- How can you tell if an identity strategy is working?
- By checking how many accounts still rely on password only and how many privileged accesses remain permanently active; reducing those figures is a tangible sign of improvement.
