Professional Services
Your clients trust you with their most sensitive information — legal strategy, financial records, and proprietary business intelligence. A breach does not just trigger regulatory penalties; it destroys the trust your firm depends on. OAS delivers managed security, Citrix virtual workspaces, and Microsoft 365 protection that gives mid-size professional services firms the same calibre of security as large enterprises — as a fully managed service.
The Stakes Are Higher Than You Think
Law firms handle privileged legal communications and litigation strategy. Accounting firms manage financial statements, tax records, and audit working papers. Consulting firms process proprietary business strategies and competitive intelligence. All of this information is subject to POPIA, professional body regulations under the Legal Practice Act and Auditing Profession Act, and increasingly, the security expectations of your clients.
Financial services and government clients now require their professional advisors to complete security questionnaires and demonstrate adequate cybersecurity controls. Firms that cannot provide this evidence risk losing their most valuable client relationships.
At the same time, ransomware operators specifically target law firms and professional services organisations because of the sensitivity — and therefore the ransom value — of the data they hold.
How OAS Secures Professional Services Firms
OAS targets mid-size firms of 50 to 500 staff — organisations large enough to handle sensitive client data that demands proper protection, but too lean to justify a dedicated in-house security team.
Secure Remote Access With Citrix
Citrix DaaS and Azure Virtual Desktop (AVD) deliver your practice management systems, document management platforms (iManage, NetDocuments, SharePoint), accounting software, and legal research tools to any authorised device, anywhere. Client data remains in the data centre or cloud — never on the endpoint.
Partners working from client sites, associates working from home, and staff across multiple offices all get the same secure, responsive experience. Profile management ensures user settings roam across sessions. Application compatibility is maintained because everything runs server-side.
OAS helps you choose the right deployment model for your firm: Citrix DaaS for complex, multi-site environments; AVD for simpler, cost-sensitive deployments; or a hybrid approach that spans both.
Microsoft 365 Security and Collaboration
Microsoft Defender for Office 365 protects against phishing, safe attachments, and safe links — critical defences for professional services where business email compromise targeting partner email accounts is the primary threat vector.
Information barriers prevent conflicts of interest across client matters. Data loss prevention (DLP) controls protect against accidental sharing of confidential documents. Microsoft Purview supports data classification and retention policies aligned to your professional obligations.
Autonomous Endpoint Protection
SentinelOne EDR protects every firm device — partner laptops, staff desktops, and mobile devices. Ransomware rollback restores affected client files automatically. Protection continues even when devices travel beyond your corporate network — essential for a mobile professional workforce.
Managed Security — Protect, Detect, Recover
The Three Pillar framework — SentinelOne (Protect), N-able RMM (Detect), and Cove Data Protection (Recover) — gives your firm 24/7 security monitoring, automated patching, and cloud backup. No need to hire cybersecurity specialists. OAS manages it all.
Backup for Mobile Workers
Cove Data Protection backs up partner and associate laptops at the workstation level, plus Microsoft 365 data (Exchange, OneDrive, SharePoint, and Teams). Direct-to-cloud backup works from any location — no need to connect to the office network. Your firm's data is protected regardless of where your people work.
Zero Trust Network Access
Citrix Secure Private Access replaces traditional VPN for remote workers. Your lawyers and consultants access firm resources securely from client sites and home offices — faster, simpler, and more secure than VPN. No full network access exposure. No complex VPN client management.
Virtual CIO Services
Many professional services firms lack a dedicated IT leader. OAS provides virtual CIO (vCIO) services — technology roadmaps, budget planning, security posture assessments, and vendor management. Strategic IT guidance without the cost of a full-time executive hire.
Your Clients Expect You to Be Secure
Client due diligence questionnaires are no longer optional. Financial services, government, and multinational clients increasingly require their professional advisors to demonstrate:
- Endpoint detection and response on all devices
- Encrypted, tested backup and recovery capability
- Secure remote access controls
- Data loss prevention measures
- Documented POPIA compliance
OAS's managed security framework provides the technical controls and compliance documentation your firm needs to satisfy these requirements with confidence.
