FAQs

Questions, answered

The things locals ask us most.

What cybersecurity services do you offer?
Reliable Computers protects Sydney and St George businesses with managed antivirus, email and spam filtering, phishing protection, patching, monitoring, tested backups, Microsoft 365 hardening, staff training and fast incident response.
Do small businesses really need cybersecurity?
Yes — small businesses are frequently targeted precisely because they’re less defended. The Australian Cyber Security Centre urges all businesses to adopt baseline protections; Reliable Computers implements practical, proportionate defences aligned to that guidance.
How much does cybersecurity cost for a small business?
Cybersecurity is scoped to your size and risk and quoted up front — typically far less than the cost of a single breach or day of downtime. Reliable Computers starts with a security review to identify gaps, then prices a right-sized plan.
We’ve been hacked — can you help?
Yes. Reliable Computers provides incident response: containing the threat, safely removing malware or ransomware, recovering data where possible, restoring systems, and hardening everything to prevent it happening again. Call 1800 753 991.
Can you remove ransomware without losing our data?
Often, yes — especially where tested backups exist. We remove the ransomware safely, restore from clean backups, and close the entry point. This is exactly why we pair security with regularly tested backups.
Do you provide email security and phishing protection?
Yes. We configure advanced spam filtering, phishing and impersonation protection and secure Microsoft 365 settings, reducing the scam, malware and fraud emails that reach your staff.
How do you secure Microsoft 365?
By applying best-practice configuration: multi-factor authentication, conditional access, audit logging, safe-attachment and link protection, and least-privilege permissions — the controls many businesses leave switched off by default.
Do you align with Australian security standards?
Yes. Reliable Computers works to ITIL and ISO-aligned practices and applies controls consistent with the Australian Cyber Security Centre’s Essential Eight, tailored to each business’s risk.
Do you train staff to spot scams?
Yes. Because people are the most common entry point, we provide practical security awareness guidance so staff can recognise phishing, suspicious links and fraudulent payment requests.
Why trust Reliable Computers with our security?
An award-winning MSP (CRN MSP of the Year 2024) established in 2009 and rated 4.8 stars from 232 reviews, Reliable Computers combines local accountability with certified expertise and a registered Oatley address — not an anonymous helpdesk.
