Enterprise IT Security and Managed Services for South Africa

Enterprise-grade managed security and Citrix virtualisation for South African businesses. 40+ years of trusted IT partnership. Protect. Detect. Recover.

As a leading IT security company in South Africa, OAS helps businesses navigate a rapidly evolving threat landscape — ransomware, regulatory compliance, and the shift to remote work demand more than traditional IT support. OAS delivers enterprise-grade managed security, Citrix virtual workspaces, and Microsoft cloud services, backed by over 40 years of trusted partnership.

Protect. Detect. Recover.

Our Three Pillar Managed Security framework addresses the full lifecycle of a security incident. Three best-of-breed technologies — SentinelOne autonomous endpoint protection, N-able 24/7 monitoring, and Cove immutable cloud backup — work together to safeguard your data, your operations, and your reputation.

- Protect — SentinelOne AI-driven endpoint detection neutralises ransomware and zero-day threats before they spread - Detect — N-able RMM provides continuous monitoring across every endpoint, with automated alerting and remediation - Recover — Cove Data Protection delivers encrypted, immutable cloud backups that ransomware cannot reach

This is not three separate products bolted together. It is a unified, managed security service — deployed, monitored, and maintained by OAS's certified engineers.
