Healthcare
Healthcare organisations manage some of the most sensitive personal data in existence. Patient records, clinical imaging, and laboratory results demand airtight security — and the consequences of a breach extend far beyond regulatory penalties. OAS delivers enterprise-grade managed security, Citrix virtual workspaces, and compliant backup solutions purpose-built for healthcare environments across South Africa.
The Challenge Facing Healthcare IT
South Africa's healthcare sector operates under constant pressure. Ransomware campaigns target hospitals and medical groups more than any other industry worldwide. Staff access patient records from multiple facilities, on shared workstations, and increasingly from remote locations. Regulatory obligations under POPIA and HIPAA (for international clients) require documented security controls and auditable data protection measures.
A single breach can expose thousands of patient records, trigger regulatory action, and damage the trust your patients place in your organisation.
How OAS Protects Healthcare Organisations
OAS combines three proven technologies into a unified managed security service — designed to protect patient data at every layer of your IT environment.
Secure Clinical Application Delivery
Citrix virtual desktops deliver your electronic health record (EHR) systems, practice management software, and medical imaging applications (PACS/RIS) to any authorised device. Patient data never leaves your data centre. Clinicians access the applications they need from nursing stations, consulting rooms, or remote locations — without sensitive information ever residing on the endpoint.
As Southern Africa's longest-standing Citrix Platinum Partner, OAS brings over 40 years of virtualisation expertise to your healthcare environment. Session roaming allows clinicians to move between workstations without losing their active session. GPU acceleration supports radiology and diagnostic imaging workflows. USB redirection connects medical peripherals securely within the virtual desktop.
Autonomous Endpoint Protection
SentinelOne AI-driven endpoint detection and response (EDR) runs on every device across your facilities — administration workstations, nursing stations, and mobile devices. It neutralises ransomware, zero-day threats, and phishing payloads before they can spread. If ransomware does reach a device, SentinelOne's rollback capability restores affected files automatically.
This is not traditional antivirus. SentinelOne uses behavioural AI to detect threats that signature-based tools miss entirely.
Proactive Monitoring Across Every Facility
N-able Remote Monitoring and Management (RMM) provides continuous, 24/7 visibility across your clinical infrastructure. Automated alerting identifies issues before they affect patient care. Patch management keeps operating systems and clinical applications up to date — reducing the vulnerabilities that attackers exploit.
For healthcare groups operating across multiple sites, N-able's multi-tenant architecture gives OAS centralised visibility while maintaining strict separation between facilities.
Compliant Backup and Data Protection
Cove Data Protection delivers encrypted, immutable cloud backups that ransomware cannot reach. Configurable retention policies support both POPIA requirements (retain only as necessary) and HIPAA archiving obligations (retain protected health information for six years). Your patient data is protected, recoverable, and compliant.
Network Segmentation and Access Control
Citrix NetScaler and network segmentation controls isolate clinical systems from administrative networks and guest Wi-Fi. This segmentation ensures that a compromised device in one area of your network cannot reach critical clinical infrastructure.
Compliance You Can Document
Healthcare IT audits demand more than good intentions. OAS provides compliance-ready documentation that maps your security controls directly to POPIA, HIPAA, and Health Professions Act requirements. When auditors ask for evidence, you have it.
Our Three Pillar Managed Security framework — Protect, Detect, Recover — addresses the full lifecycle of a security incident, giving your compliance team a clear, defensible security posture.
