Antivirus and EDR
SentinelOne antivirus and EDR, managed by Crew IT
SentinelOne replaces old-style antivirus with AI-driven endpoint detection and response that spots and stops ransomware, malware and suspicious behaviour in real time. Crew IT deploys it, tunes it and responds to its alerts for businesses across the Gold Coast and Brisbane.
- Stops ransomware automatically
- Ransomware rollback on Windows
- Windows, macOS and Linux
Quick answer: SentinelOne is an endpoint protection platform that uses AI on each device to detect and block malware, ransomware and attacker behaviour, even when the device is offline. Its EDR features record what happened, isolate infected devices and can roll back ransomware changes on Windows. Crew IT supplies, installs and manages SentinelOne for Australian businesses.
Why SentinelOne
Protection that thinks, not just a list of known viruses
Traditional antivirus compares files to a list of known threats. SentinelOne watches what software actually does, so new and disguised attacks are caught too.
Behavioural AI
Detects malicious behaviour as it happens, including fileless attacks and threats that have never been seen before.
Ransomware rollback
On Windows devices, changes made by ransomware can be reversed, restoring affected files without a full rebuild.
Device isolation
An infected computer can be cut off from the network in one click while it stays connected to us for investigation.
Full attack story
EDR records the chain of events behind an alert, so we can see how a threat arrived and what it touched.
Works offline
Protection runs on the device itself, so laptops stay protected at home, in cafes and on the road.
Device and USB control
Policies can block unknown USB drives and risky peripherals, a common way for data to leave the business.

SentinelOne: common questions
Is SentinelOne better than Windows Defender or Norton?
SentinelOne is a business-grade EDR platform designed to stop modern threats such as ransomware and hands-on-keyboard attacks, with rollback, isolation and investigation features that consumer antivirus does not offer. Microsoft Defender for Business is also a capable option for some Microsoft 365 customers, and we will recommend what suits your licences, risk and budget.
Does SentinelOne slow computers down?
SentinelOne is lightweight and does not rely on large daily signature downloads or scheduled full scans, so most users do not notice it running.
Can SentinelOne really undo ransomware?
On Windows devices, SentinelOne can roll back changes made during an attack using its rollback feature, which can restore encrypted files. It is a powerful last line of defence, but it does not replace proper backups, which we also manage.
Does it work on Mac computers?
Yes. SentinelOne protects Windows, macOS and Linux devices, so mixed offices are covered by one platform.
Can we buy SentinelOne without a managed plan?
Yes. We can supply and manage SentinelOne as a standalone security service, or include it in a managed IT plan.
