Endpoint Protection for Perth Businesses

Why endpoint protection is the gap most Perth businesses don't see

For a Perth business with 5 to 50 staff, the device is the front door. Laptops travel between the office on St Georges Terrace, a home in Joondalup, a client site in Welshpool, and the airport lounge before a FIFO rotation. Every one of those devices logs into Microsoft 365, opens client files, and stores cached credentials. The old idea that the company network is the thing you protect stopped being true the moment your team started working from anywhere.

The reality we see across WA accounting, legal, medical and construction firms is consistent: the antivirus that shipped with the machines three years ago is still running, nobody can say which devices are encrypted, and at least one laptop in the business is two major Windows versions behind. An attacker does not need to breach a firewall when a single unpatched, unmanaged laptop with a saved password is sitting on hotel Wi-Fi. The endpoint is where the breach actually lands, and it is the one layer most owners have never been shown a clear picture of.

What actually goes wrong, and how it plays out

The common scenario is not dramatic. A staff member clicks a convincing invoice attachment, a piece of malware runs quietly with their normal permissions, and it begins encrypting files on the device and in the synced OneDrive and SharePoint folders. Because that user has access to the shared finance folder, the damage spreads to documents the whole firm relies on. By the time anyone notices files are scrambled, the device has been compromised for hours.

For a 5 to 50 staff firm, the cost is rarely just the cleanup. It is the three days the team cannot bill while you rebuild machines and restore data. It is the awkward call to a client whose matter file or patient record was on that laptop. For an accounting firm it can mean ATO portal credentials cached on a compromised device; for a legal practice, privileged client material and trust account data; for an allied health provider, patient records that fall under the Privacy Act. A second common failure is the lost or stolen laptop that was never encrypted and never enrolled, so it cannot be wiped remotely. The device walks out the door, and so does everything on it.

What makes these incidents worse for smaller firms is the lack of visibility. Without central management, nobody knows which machines were affected, whether the malware spread, or whether it is truly gone. The recovery drags on because you are guessing.

How COREWEST locks down every device, Microsoft-first

We build endpoint protection on the Microsoft tools you are already paying for inside Microsoft 365, configured properly and watched. Each one does a specific job:

• Microsoft Defender — real-time protection on every laptop and desktop, with behaviour-based detection that catches ransomware patterns, not just known virus signatures, and isolates a device the moment it acts compromised.
• Microsoft Intune — central management of every device. We enforce disk encryption with BitLocker, push security updates so no machine falls behind, and set the baseline so a device cannot reach company data unless it meets the standard.
• Entra ID and Conditional Access — only known, healthy, enrolled devices get into Microsoft 365. A personal or unmanaged machine trying to reach your data gets blocked or challenged, which shuts down a whole class of credential-theft attacks.
• Defender for Office 365 — stops the malicious attachment and phishing link before it ever reaches the device, removing the click that starts most incidents.
• Microsoft 365 Backup — protected, verifiable recovery of SharePoint, OneDrive and Exchange data, so a ransomware hit becomes a restore instead of a negotiation.

Crucially, when a device is lost or stolen, Intune lets us wipe it remotely. The laptop is gone; your client data is not exposed.

What's included, how it runs week to week, and what good looks like

Endpoint protection with COREWEST is not a product you switch on and forget. Every device in the business is enrolled, encrypted, and reporting into one place. We manage the security baseline, keep updates current, and review the Defender alerts so a genuine threat is acted on quickly rather than sitting in a console nobody reads. New starters get a device that is hardened from day one through Autopilot; people who leave have their access and devices cleanly removed so nothing stays accessible after they walk out.

Good looks like this: you can answer, on any given day, how many devices the business has, that every one of them is encrypted and up to date, and that none are running unprotected. A lost laptop is a quick remote wipe, not a Privacy Act problem. A malicious email is blocked before the click. A ransomware attempt is isolated to one device and recovered from backup, not spread across the firm. You stop guessing about your devices and start knowing.
