IAM misconfiguration: the silent threat inside your organisation

Ask most business owners where their cyber risk lives and they will point at hackers, malware, and suspicious emails. Few point at their own user accounts. Yet identity and access management (IAM) misconfiguration — who can access what, and how — is behind a significant share of real-world breaches, and it rarely triggers any alarm.

It is the former employee whose account was never disabled. The marketing intern with administrator rights on the company cloud. The shared login used by six people. The service account with a password set three years ago that has never been rotated. The Microsoft 365 tenant where multi-factor authentication is enabled but not enforced.

None of these look like an attack. All of them are open doors.

Traditional security tools watch for malicious activity — malware signatures, suspicious logins from abroad, unusual data transfers. An attacker using a legitimate, over-privileged account looks exactly like a normal user, because technically they are one. That is why identity-based attacks can sit inside a network for months.

First, enforce MFA everywhere — not just email, but VPNs, cloud consoles, and admin portals. Second, apply least privilege: every account gets the minimum access needed for its job, nothing more. Third, automate joiners and leavers: accounts are created with the right access on day one and disabled completely on the last day. Fourth, review access quarterly — you will be surprised what has accumulated. Fifth, eliminate shared accounts so every action is attributable to a person.

An IAM review is one of the fastest ways to reduce real risk in a business. Our identity and access management service audits your current state, closes the dangerous gaps, and puts the policies and automation in place to keep it that way as your team grows.
