We get asked this a lot and usually comes up when we onboard a new customer, staff log into their computers using accounts that have administrative privileges. Although this may seem convenient, it introduces significant security risks and dramatically increases the likelihood of a cyber incident.
Modern security best practice is clear: everyday user accounts should NEVER have admin access. Five key reasons are that not having admin access:
- Reduces the impact of malware and cyber-attacks
When a user with admin rights accidentally opens a malicious file, the attacker can gain full control of the device. Malware can install silently, disable security tools, spread across the network, and access sensitive systems. Without admin rights, malware is far more limited. - Stops accidental system misconfiguration
Most system failures are caused by accidental user actions. Admin accounts can remove important software, alter settings, disable protections, and break applications. Restricting access prevents disruptions caused by well-meaning users. - Protects sensitive data and business systems
Admin users can access system files, other users’ data, credentials, and critical configurations. If an attacker compromises an admin account, they gain full access instantly. Standard accounts limit exposure. - Supports Zero-Trust and security standards
Cyber Essentials, ISO 27001, NCSC guidance, and Microsoft Best Practice all strongly recommend least-privilege access. - Reduces the success rate of phishing attacks
Phishing emails often try to install software, run scripts, or harvest passwords—actions that typically require admin privileges. Removing admin rights makes phishing attacks much less effective.
Removing admin rights is one of the simplest and most effective ways to strengthen security. It reduces cyber risk, prevents accidental damage, and supports modern security standards. Organisations should use standard accounts for everyday use and reserve admin access for IT professionals only.
