Ransomware Protection for Australian Businesses
Ransomware protection requires a layered approach — endpoint protection, email filtering, network segmentation, backup strategy and incident response capability. PIP builds and manages the full ransomware protection stack for Australian businesses, because effective protection is a system, not a single product.
What is ransomware?
Ransomware is malicious software — a dangerous type of malware — that encrypts files and systems across your systems, making them inaccessible. The ransomware operator then demands a ransom payment in exchange for the decryption key. Most ransomware attacks begin with phishing emails. Ransomware attacks occur, compromised credentials or unpatched software vulnerabilities — not sophisticated exploits. Ransomware attacks target all critical sectors and businesses of all sizes, with ransomware attacks occurring across every system, threatening access to files, data and business-critical systems alike.
Many modern ransomware variants also exfiltrate sensitive data before encrypting files — meaning even if the business can restore from backup, the attacker may still threaten to publish the data. This is double extortion, and it means ransomware attacks can trigger data breach notification obligations under the Privacy Act 1988 NDB scheme regardless of whether the ransom is paid.
The Cyber Security Act 2024 introduced mandatory reporting obligations for ransomware payments in Australia. PIP advises clients on these obligations and helps organisations understand their response plan before an attack occurs — not after. Ransomware prevention starts with understanding ransomware threats and building the layered ransomware protection solutions that stop ransomware before it can encrypt your critical data.
How ransomware attacks work
Understanding the ransomware attack chain is essential protection strategy. Each stage represents a point where the right protection measures can stop the attack — or where a gap lets it through.
Initial Access
Most ransomware attacks begin with a phishing email — malicious links or attachments that execute malicious code when clicked. Other common entry points include compromised credentials (human error, password reuse), unpatched operating system and software vulnerabilities, and exposed remote access connections. This is where endpoint protection, email security and multi-factor authentication stop the attack before it starts.
Lateral Movement
Once inside and before encryption begins, ransomware operators move laterally through the network — privilege escalation, identifying valuable data stores, establishing persistent access. This stage can last days or weeks. Network segmentation and access controls limit the attacker’s movement and contain the threat to the compromised system.
Data Exfiltration
Modern ransomware variants frequently exfiltrate sensitive data before encryption — giving the attacker a second lever: pay the ransom to decrypt your files, or the data is published. This double extortion means that even businesses that survive ransomware attacks with tested backups may still face data loss and a data breach notification obligation.
Encryption and Ransom Demand
The ransomware payload encrypts files across the network — including mapped drives and connected backup systems if they are not properly isolated. The ransom note appears. Ransomware detection tools powered by advanced threat intelligence and machine learning can detect suspicious behavior and halt the threat at this stage — but isolation is the best practice once encryption begins.
PIP’s layered ransomware protection
No single product provides complete ransomware protection. Effective ransomware protection requires multiple layers — each addressing a different stage of the ransomware attack chain. PIP builds and manages the full ransomware protection stack as part of your managed IT service.
Endpoint Protection
Enterprise-grade endpoint security software and endpoint detection monitors every device for suspicious behavior — detecting ransomware activity before it can encrypt files across your environment. PIP deploys and manages endpoint security as antivirus software that uses machine learning and threat intelligence to stop ransomware and other malware on all managed devices, including mobile devices and on-premises systems.
Email Protection
The majority of ransomware attacks and ransomware infections start with phishing emails. PIP’s email security configuration includes gateway filtering, malicious attachment scanning, URL rewriting and phishing simulation training — reducing the attack surface at the most common ransomware entry point. See PIP’s email security services.
Multi Factor Authentication
Compromised credentials and strong passwords alone are not enough to prevent ransomware infections via credential theft. Multi-factor authentication adds a second factor — so a stolen password alone cannot gain access to email, access remote systems or access cloud services. PIP configures multi-factor authentication across every managed environment.
Patch Management
Unpatched known vulnerabilities in operating system and application software are routinely exploited by ransomware operators. PIP’s managed patch management deploys patches within ASD Essential Eight-compliant timeframes, keeping systems regularly updated and minimising the window of exposure that ransomware threats exploit.
Network Segmentation
Network segmentation and network security measures limit how far ransomware can spread once inside the environment. By separating systems and restricting movement between segments, a compromised endpoint cannot immediately reach servers, backup systems or sensitive data stores. Segmentation is a best practice that stops ransomware from encrypting data across the entire network.
Managed Backup and Recovery
Tested, isolated regular backups are the last line of defence against ransomware attacks. PIP configures backup to isolated and offsite locations that are not directly reachable by ransomware on the live network — and conducts quarterly restoration tests to confirm backups can actually be restored. Backup that stores important files without testing is not protection. PIP’s backup strategy ensures business continuity and protects against data loss when a ransomware attack hits.
“The ransomware incidents that cost businesses the most are almost always the ones where the backup looked fine until they needed it. The backup was running — it just hadn’t been tested. Or the backup destination was a mapped network drive that the ransomware encrypted along with everything else. Or the last good backup was from three months ago because nobody noticed it had been failing. Tested, isolated backup is the difference between a ransomware attack that costs you a day and one that costs you a month.”

Ransomware protection includes a response plan, not just prevention. If ransomware gets through, PIP activates the response plan immediately.
Contain
PIP isolates affected systems and compromised system components immediately to stop ransomware from spreading further across the network. Isolation preserves forensic evidence and limits the scope of the ransomware attack.
Recover
PIP activates the backup and recovery plan. For clients with tested, isolated backups, recovery from the ransomware attack begins immediately. PIP manages the restoration process and validates system integrity before bringing affected systems back online — restoring access to all the data and files as quickly as possible.
Report
If the ransomware attack has resulted in a reportable data breach under the Privacy Act NDB scheme, PIP assists with the notification process. The Cyber Security Act 2024 also introduces mandatory reporting for ransomware payments. PIP advises on these obligations and supports the response and communication process.

Is your ransomware protection actually tested?
Most businesses have backup. Fewer have tested, isolated backup that can survive a ransomware attack. PIP’s ransomware protection solutions include quarterly backup restoration testing — so you know your recovery plan works before you need it.
Talk to PIP →Ransomware protection — common questions
No single product provides complete ransomware protection — the most effective ransomware protection solutions combine multiple layers. PIP’s ransomware protection stack combines endpoint security software (to detect ransomware, other malware and dangerous types of malicious software), email filtering (to block phishing emails and malicious links at the most common entry point), multi factor authentication (to protect against credential compromise), managed patch management (to close known vulnerabilities), network segmentation (to limit lateral movement) and tested, isolated backup (to ensure recovery is possible).
Each layer addresses a different stage of the ransomware attack chain. Ransomware prevention best practices require all layers working together — not a single security software product.
Immediately isolate affected systems — disconnect them to stop the threat from spreading and encrypting data on other systems. Do not restart or attempt to repair affected machines (this can destroy forensic evidence needed for the response process).
Contact PIP immediately — PIP will activate the response plan, assess the scope of the ransomware attack, begin recovery from backup and advise on notification obligations under the Privacy Act NDB scheme. Do not pay the ransom without first understanding your recovery options and the legal implications — the Cyber Security Act 2024 requires reporting of ransomware payments in certain circumstances.
Backup is essential — but backup alone is not ransomware protection. The backup must be isolated from the live network (so ransomware cannot encrypt it along with everything else), regularly tested (so you know it can actually be restored) and current (so the recovery point is close to the time of the ransomware attack).
Backup also does not prevent ransomware infections or protect against double extortion (data exfiltration before encrypting files). A complete ransomware protection strategy also includes endpoint protection, email filtering, multi-factor authentication, patch management and an incident response plan. Educate employees about phishing attacks and social engineering to reduce human error — the most common ransomware entry point.
PIP’s managed protection stack is configured, monitored and maintained as part of the managed IT service — it does not require manual activation. Endpoint protection runs continuously on all covered devices using machine learning, advanced threat intelligence and ransomware detection to identify and stop threats in real time. Email filtering operates at the gateway. Patch management is automated and regularly updated. Regular backups run on defined schedules and are tested quarterly.
The only component that requires human judgement is the response process — which PIP activates immediately on detection of a ransomware event. PIP’s protection systems are designed to protect your files and protect your business around the clock without manual intervention, maintaining your security posture against evolving ransomware threats and new threats.
