Overview

Protect your people, identities and data

Microsoft Intelligent Security Association member

Microsoft 365 is where most of your business happens, which makes it a prime target. Weak access controls, over-shared data and unmanaged identities are among the most common ways attackers gain a foothold in an organisation.

BUI helps you secure Microsoft 365 across the areas that matter most: access control, identity management and data protection. We make sure the right people have the right access to the right tools at the right time, protecting you from insider threats and unauthorised access.

Our Approach

Microsoft 365 security in action

01
Identity & Access
Control who gets in

We govern access to your resources with conditional access, multi-factor authentication and least-privilege controls, so only the right people reach the right tools, and insider and account-takeover risks are reduced.

02
Data Protection
Guard your information

We help you secure sensitive information and meet obligations under GDPR, POPIA and other regulations, using Microsoft Purview and information-protection controls to classify, label and safeguard your data.

03
Threat Protection
Defend against attacks

We deploy Microsoft Defender for Office 365 and related tooling to protect against phishing, malware and business email compromise, keeping the collaboration tools your teams rely on safe.

“Most breaches do not start with clever malware. They start with an identity or a permission that was left wide open. Microsoft 365 security is where you close those doors.” Willem Malan · Chief Technology Officer, BUI
