Think of Identity and Access Management (IAM) as the digital equivalent of keys to your building. Just as you wouldn’t give every employee a master key to every room, you shouldn’t give every team member access to every system and file in your business. IAM ensures the right people have access to the right information at the right time—and nobody else does.
When employees leave your company, do their digital access privileges leave with them? If you can’t answer that confidently, you have a problem. Former employees with active accounts represent one of the biggest security risks businesses face. Additionally, when current employees have more access than they need for their jobs, you’re creating unnecessary risk exposure.
Consider this scenario: Your bookkeeper needs access to financial software but doesn’t need access to customer service emails or product development files. With proper IAM, they get exactly what they need—nothing more, nothing less. This approach, called “least privilege access,” dramatically reduces your risk if their account gets compromised.
Poor access management costs businesses in multiple ways. Beyond the obvious risk of data theft, you face compliance violations, productivity losses when employees can’t access what they need, and the administrative burden of managing access manually. Companies with strong IAM practices report 50% fewer security incidents and significantly lower breach costs.
Start with these essential IAM components:
Multi-Factor Authentication (MFA) should be your first priority. This means employees need something they know (password) plus something they have (phone for text codes) to log in. Services like Microsoft 365, Google Workspace, and most business applications now include MFA options. The cost is minimal, but the protection is substantial.
Single Sign-On (SSO) solutions like Okta, Azure AD, or Google Workspace allow employees to log in once and access all their approved applications. This improves security while making life easier for your team.
Regular access reviews should happen quarterly. Create a simple spreadsheet listing who has access to what, and review it with department managers. Remove access for departed employees immediately—not next week, not when you remember, but the day they leave.
