The Under-Utilisation Problem
Most South African businesses use less than 30% of the Microsoft 365 capabilities included in their existing licence. Organisations pay for enterprise-grade security, compliance, and productivity tools — then leave them unconfigured. Exchange Online runs without Data Loss Prevention (DLP) policies. Teams operates without conditional access controls. Defender sits dormant while third-party security tools duplicate functionality already included in the subscription.
OAS audits your current M365 environment, identifies inactive security features, and activates the protection you have already paid for. The result is stronger security posture without additional licence spend.
Full M365 Deployment
OAS delivers end-to-end Microsoft 365 deployment across the complete productivity suite:
Exchange Online
enterprise email with advanced threat protection, journaling, and retention policies configured from day one
Microsoft Teams
collaboration platform with governance controls, guest access policies, and telephony integration where required
SharePoint Online
intranet and document management with proper information architecture, permissions models, and sensitivity labels
OneDrive for Business
secure file sync with Known Folder Move (KFM) deployment, conditional access, and DLP policies applied
Every deployment follows OAS's structured engagement process: discovery, architecture, pilot, production rollout, and user enablement.
Security Configuration
M365 security is only as strong as its configuration. OAS implements:
Conditional Access
location-based, device-based, and risk-based access policies through Microsoft Entra ID
Data Loss Prevention (DLP)
policies across Exchange, Teams, SharePoint, and OneDrive to prevent sensitive data exposure
Defender Policies
anti-phishing, anti-malware, Safe Links, and Safe Attachments configured to organisational risk profile
Microsoft Defender Suite (E5)
Microsoft 365 E5 includes the full Defender suite, delivering integrated extended detection and response (XDR):
Defender for Endpoint P2
endpoint detection and response with automated investigation and remediation
Defender for Office 365 P2
advanced threat protection for email, with attack simulation and threat explorer
Defender for Identity
on-premises Active Directory monitoring for lateral movement and credential compromise
Defender for Cloud Apps
cloud access security broker (CASB) for shadow IT discovery and app governance
Entra ID P2
identity protection with risk-based conditional access, Privileged Identity Management (PIM), and access reviews
Security Copilot
Microsoft 365 E5 includes Security Copilot at 400 Security Compute Units (SCUs) per 1,000 users. Security Copilot provides AI-assisted incident investigation, threat hunting, and posture management across the Defender suite. OAS configures SCU allocation and integrates Copilot into existing security operations workflows.
Microsoft 365 E7 — Frontier Suite
The newly announced M365 E7 "Frontier Suite" builds on E5 by bundling:
- Microsoft 365 Copilot — AI assistance embedded across Word, Excel, PowerPoint, Outlook, and Teams
- Agent 365 — autonomous AI agents for workflow automation, approvals, and business process orchestration
E7 positions organisations for the agentic AI era without separate Copilot add-on licensing.
Copilot Wave 3
Copilot Wave 3 introduces agentic capabilities that move beyond simple prompts:
Agent Mode
Copilot takes multi-step actions across M365 applications autonomously
Cowork Feature
Copilot works alongside users in real time, suggesting actions and completing tasks proactively
Custom Agents
organisations build domain-specific agents using Copilot Studio without code
OAS assists with Copilot readiness assessments, data governance prerequisites, and rollout planning.
Microsoft Purview
Microsoft Purview provides the compliance and data governance layer across M365:
Information Protection
sensitivity labels, encryption, and rights management applied to documents and emails
Data Loss Prevention
unified DLP policies enforced across Exchange, Teams, SharePoint, OneDrive, and endpoints
Insider Risk Management
behavioural analytics to detect potential data exfiltration or policy violations
eDiscovery
legal hold, content search, and case management for regulatory and litigation requirements
Purview configuration is essential for POPIA compliance and data sovereignty requirements in South Africa.
Defender Experts Suite
For organisations that require fully managed security, Microsoft Defender Experts provides:
- Defender Experts for XDR — managed extended detection and response across endpoints, email, identity, and cloud apps
- Defender Experts for Hunting — proactive threat hunting by Microsoft's security analysts
The Defender Experts Suite delivers fully managed MXDR with up to 66% discount available through December 2026. OAS facilitates procurement, onboarding, and integration with existing security operations.
