Endpoint Detection & Response (EDR) for Melbourne Businesses

Traditional antivirus matches files against a database of known malware signatures — it can only detect threats that have already been catalogued. Endpoint Detection and Response (EDR) uses behavioural analysis and AI to detect suspicious activity regardless of whether the specific threat has been seen before. EDR also provides investigation tools — process trees, network connections, timeline views — that let security teams understand exactly what happened during an incident. For Melbourne businesses, EDR is the modern replacement for antivirus, not an add-on to it.

Sophos Intercept X uses a technology called CryptoGuard that monitors file system activity for patterns consistent with ransomware encryption. When encryption behaviour is detected — even from a brand-new ransomware variant — CryptoGuard terminates the process and rolls back any encrypted files to their pre-encryption state. This happens in seconds, before the ransomware has time to spread. Combined with automated network isolation, this means most ransomware incidents are contained to the initially-infected device with no data permanently lost.

Microsoft Defender (included with Windows) provides basic antivirus protection and has improved significantly in recent years. However, it does not provide the same level of behavioural detection, investigation tools, or managed response capability as Sophos Intercept X EDR managed by a security team. Defender is adequate for home users. For Melbourne businesses with sensitive client data, legal or regulatory obligations, or any cyber insurance requirement, a fully managed EDR solution is the appropriate standard.

Modern EDR agents like Sophos Intercept X are designed to have minimal performance impact. On supported hardware — machines with an SSD and at least 8GB RAM — most users report no noticeable performance difference. On ageing hardware with spinning hard drives or 4GB RAM, some impact may be felt. As part of our EDR deployment, we assess device specifications and flag any hardware that may need upgrading.

When Sophos Intercept X detects a confirmed threat, our monitoring system generates an alert and our Melbourne security team is notified. Depending on the severity, the response may include: automated isolation of the affected endpoint, remote investigation of the process and file activity, threat removal and remediation, and a post-incident report. You are notified throughout the process. For critical incidents, we escalate immediately and can have a senior engineer in your office within hours if required.

EDR is now explicitly listed on most Australian cyber insurance application forms. Insurers ask whether you have an EDR solution deployed on all endpoints — not just antivirus. Without EDR, you may be declined coverage or face significantly higher premiums. With a managed EDR solution from CX IT Services, you can confidently answer yes to this question and provide evidence if required.

Managed EDR pricing is typically per endpoint per month — covering desktops, laptops, and servers. For a Melbourne business of 10-30 users, the total monthly cost is generally comparable to a single hour of incident response. We provide fixed per-seat pricing with no additional charges for alert investigations or threat response under our standard SLA. Volume pricing applies for larger environments and is included in our managed IT proposals.

Sophos Intercept X integrates natively with the Sophos XGS managed firewall through Synchronized Security, allowing the two products to share threat intelligence and automate network isolation responses. It also integrates with Microsoft 365 via API for cross-platform threat correlation. For businesses using SIEMs or other security platforms, Sophos Central provides API-based log export. We map the integration requirements during onboarding and configure the connections as part of the deployment.

Medical practices are a high-value target because patient health records command premium prices on criminal marketplaces and practices often run legacy medical imaging or practice management software that is difficult to patch. We configure EDR policy exclusions carefully to avoid interfering with clinical software while maintaining full protection on general-purpose endpoints. For practices subject to the My Health Records Act and the Australian Privacy Act, managed EDR provides the audit trail and incident response capability required to demonstrate compliance following a breach.

Yes. Sophos Intercept X operates independently of your network connection — the agent runs on the endpoint and communicates with the Sophos Central management platform over the internet. Remote workers, travelling staff, and devices on home networks receive identical protection to office-based devices. This is particularly important for Melbourne professional services firms where partners and senior staff regularly work from home or client sites.
