Transforming IT, Cybersecurity & Secure AI Adoption for an Australian Legal Firm

Case Study: Transforming IT, Cybersecurity & Secure AI Adoption for an Australian Legal Firm 

Industry: Legal & Professional Services

The Challenge 

A growing Australian legal and advisory firm engaged CyberAgency Group to take responsibility for its end-to-end technology environment. 

Like many professional services businesses, the firm relies heavily on Microsoft 365, email, cloud applications and digital collaboration to manage highly sensitive business and client information. 

Following a review of the environment inherited from the previous IT provider, CyberAgency identified opportunities to significantly strengthen the organisation’s cybersecurity posture and introduce a more proactive approach to technology management. 

Key priorities included: 

• Strengthening Microsoft 365 security controls 

• Improving identity and user access protection 

• Hardening endpoints and devices 

• Increasing protection against email-based threats 

• Improving visibility across the technology environment 

• Establishing stronger security policies and standards 

• Reducing cybersecurity risk associated with sensitive client information 

• Improving Essential Eight maturity 

• Moving from reactive IT support to proactive technology management 

• Preparing the organisation for the safe adoption of AI 

The objective was not simply to change IT providers. 

It was to establish a stronger technology and cybersecurity foundation that could support the firm’s growth, protect sensitive information and allow emerging technologies such as AI to be adopted safely. 

The Solution 

CyberAgency Group assumed responsibility for the organisation’s end-to-end technology environment and implemented a comprehensive cybersecurity uplift. 

Rather than treating IT support and cybersecurity as separate services, CyberAgency introduced an integrated managed technology and security model. 

The uplift included: 

• Microsoft 365 security hardening – strengthening identity, authentication, access and security configurations across the Microsoft environment 

• Endpoint security – improving protection and management of corporate devices 

• Email security – strengthening controls against phishing, impersonation, malicious attachments and other email threats 

• Identity & Access Management – improving MFA, account security and access controls 

• Essential Eight alignment – implementing and strengthening security controls against recognised Australian cybersecurity best practices 

• Security monitoring – increasing visibility of potential threats and suspicious activity 

• Patch and vulnerability management – proactively addressing technology risks before they become security incidents 

• Data protection – introducing stronger controls around business and client information 

• Managed IT support – providing ongoing user, device, Microsoft and technology support 

• Technology strategy – establishing a structured technology and cybersecurity roadmap aligned with the firm’s future growth 

Instead of waiting for problems to occur, CyberAgency’s role became one of proactively identifying risk, improving security and continuously strengthening the environment. 

Moving From Cybersecurity Uplift to Secure AI Adoption 

With the core technology environment significantly strengthened, the next stage of the partnership is focused on AI. 

The organisation is now exploring how AI can improve productivity and efficiency across the business. 

However, introducing AI into a legal environment requires more than simply enabling new tools. 

Employees may potentially interact with confidential client information, commercially sensitive documents, contracts and other protected information. Without appropriate controls, the use of public or unapproved AI services can introduce new risks around data leakage, privacy, access and governance. 

CyberAgency is therefore helping the organisation develop an AI adoption strategy with security built in from the beginning. 

This includes: 

• Establishing approved and unapproved AI usage 

• Developing AI governance policies 

• Protecting confidential and sensitive information 

• Implementing appropriate data access controls 

• Reducing Shadow AI risk 

• Reviewing Microsoft Copilot and other enterprise AI opportunities 

• Ensuring AI tools operate within appropriate security boundaries 

• Educating employees on responsible AI usage 

• Establishing guardrails before AI adoption expands across the organisation 

The objective is simple: 

Enable the business to take advantage of AI without losing control of its data. 

Why This Approach Worked 

Cybersecurity cannot be treated as a one-off project. 

The organisation needed a technology partner capable of managing day-to-day IT while continuously improving cybersecurity, identifying emerging risks and helping management make informed technology decisions. 

By managing the complete environment, CyberAgency has visibility across users, devices, Microsoft 365, cybersecurity controls and the broader technology stack. 

This enables CyberAgency to look beyond individual support tickets and focus on the organisation’s overall technology risk and long-term strategy. 

The relationship has therefore evolved beyond traditional managed IT services. 

CyberAgency operates as the organisation’s technology and cybersecurity partner, supporting both immediate operational requirements and longer-term initiatives such as cybersecurity maturity, data protection and secure AI adoption. 

The Outcomes 

Significant Cybersecurity Uplift

The organisation has moved from its previous technology environment to a considerably stronger security posture, with improved controls across Microsoft 365, identities, devices, email and business information. 

Proactive Rather Than Reactive IT 

Technology management has shifted away from waiting for users to report problems toward proactively identifying risks, maintenance requirements and improvement opportunities. 

Stronger Protection of Sensitive Information 

Additional security controls provide greater protection around confidential business and client information — particularly important within the legal sector. 

Improved Security Governance 

Cybersecurity policies, technical controls and ongoing security improvements are now managed as part of a structured roadmap rather than individual technology projects. 

Essential Eight Alignment 

Security improvements have strengthened the organisation’s alignment with the Australian Cyber Security Centre’s Essential Eight framework and provided a clearer path for continued cybersecurity maturity. 

One Technology & Security Partner 

Rather than managing separate IT and cybersecurity providers, the organisation has one partner responsible for the complete technology environment — improving accountability, visibility and coordination. 

Ready for AI 

With a stronger security foundation in place, the organisation can now explore AI adoption with appropriate governance, data protection and security guardrails. 

From Managed IT to a Secure Technology Strategy 

For professional services organisations, technology is no longer simply about keeping computers running. 

Cybersecurity, data protection and AI are rapidly becoming interconnected. 

Organisations adopting AI without first understanding their Microsoft environment, data exposure and security posture can introduce significant new risks. 

CyberAgency Group helps organisations take a different approach: 

Secure the environment. Protect the data. Establish the guardrails. Then enable AI. 

If your organisation is reviewing its current IT provider, concerned about its cybersecurity posture or considering Microsoft Copilot and AI adoption, CyberAgency can help establish a secure foundation for what comes next.
