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.
