How do I know if my network is secure?

Most home and small business networks have vulnerabilities — default passwords, outdated firmware, weak encryption. We can check in about an hour.

What's included in a network security audit?

We scan all connected devices, check router/firewall config, test WiFi encryption, look for open ports, review passwords, and check firmware. Written report included.

Can you help if I've already been hacked?

Yes. We contain the breach, remove malware, reset credentials, and secure your network. Call 1300 600 004 immediately for active incidents.

Do you service businesses or just homes?

Both. Home users and small businesses (1-50 staff). For larger businesses, we can discuss managed security.

Geeks Brisbane provides practical, plain-English network security and internet security services to homes and small businesses across Brisbane, the Gold Coast, Sunshine Coast and South-East Queensland. We're based at Level 4, 260 Queen Street in Brisbane CBD, and we do the work most of the big "enterprise cyber security" firms in Brisbane won't touch — securing real NBN connections, real Wi-Fi networks, real Microsoft 365 tenants and real family or staff devices for people who just want their network to actually be safe.

The two most common questions we hear: "How do I know if my home network is secure?" and "Do I need cyber security if I only have 5 staff?". The honest answer to both: probably yes, and probably more than you think. Default NBN router passwords, recycled Wi-Fi keys, missing MFA on Microsoft 365, and unpatched firmware are the actual ways small Brisbane networks get compromised — not Hollywood-style hackers. We close those gaps quickly and tell you the truth about what matters and what doesn't.

Network Security Services We Provide

Eight core services that cover almost every home and small-business network in Brisbane. Most jobs combine 2–3 of these in a single 1–2 hour visit.

Recent Brisbane Network Security Jobs

A sample of real network security and internet security work Geeks Brisbane technicians completed for Brisbane homes and small businesses recently. Names are first-name only for privacy.

Bulimba home · Mon afternoon

"My Wi-Fi password is on a sticky note on the router — is that bad?"

Rotated the Wi-Fi key to a strong passphrase, set up a separate guest network for visitors and IoT devices, enabled WPA3, disabled WPS. Walked Anna through the new Wi-Fi names and labelled both with her phone label-printer.

South Brisbane SMB · Tue morning

"Our office Microsoft 365 got hacked overnight"

Account-takeover via phished MFA. Reset all Microsoft 365 passwords, enforced number-matching MFA, removed three malicious inbox rules forwarding invoices to Gmail, audited 90 days of sign-in logs and reported to bank. Cleaned up within 3 hours.

Indooroopilly home · Wed afternoon

"Smart cameras pinging weird IPs in China"

Old Wyze/Tuya cameras on an open SSID. Moved entire IoT fleet to a segregated VLAN, blocked outbound traffic except to known cloud endpoints, replaced two cameras that had no recent firmware updates. Re-armed the alarm.

Milton 8-staff office · Thu morning

"BEC scam paid the wrong supplier $14,200"

Cleaned compromised mailbox, enforced MFA on every Microsoft 365 user, set up DMARC at reject, added external-sender warning banner, ran a phishing-awareness session with staff, helped director document the incident for the cyber insurance claim.

Carindale family · Fri evening

"Kids are watching things they shouldn't on the Wi-Fi"

NextDNS family profile applied at the router level so every device on the network (phones, school iPads, smart TV) is filtered by default. Per-child schedules so devices stop accessing entertainment domains after 9pm.

Ipswich café · Sat afternoon

"EFTPOS keeps dropping out and customers are mad"

Café Wi-Fi was on a $40 Bunnings router sharing a single SSID with the POS, staff phones, and customers. Reconfigured into 3 separate networks (POS, staff, guest), set QoS for the EFTPOS terminal, replaced router with a UniFi Express. No more dropouts.

Brisbane Home Network Security Checklist

Most home networks fail at least 5 of these 12 items. We tick them all off in a single 1-hour visit, and leave the checklist with you as a written record.

The 12-point home network security check

NBN router admin password changed from default and stored in a password manager
Router firmware up to date (most NBN routers haven't been updated since you got them)
Wi-Fi encryption is WPA3 or WPA2-AES, not WEP or WPA mixed-mode
Wi-Fi passphrase is unique, 14+ characters, and not shared with neighbours
WPS is disabled (it's a known security weakness on most consumer routers)
Remote management / "router web access from internet" is disabled
UPnP is disabled or limited (especially for IoT cameras)
Guest Wi-Fi network exists for visitors, holiday rentals, and IoT devices
DNS filtering applied at router level (NextDNS, Cloudflare Families, or CleanBrowsing)
MFA enabled on Gmail/iCloud/Microsoft email and online banking
Password manager (Bitwarden, 1Password, Apple Passwords) used by every adult in the home
Email addresses checked at haveibeenpwned.com — exposed passwords rotated

Small Business vs Home — Different Risks, Different Fixes

Network security needs are different for a family of four and a 10-staff small business. Here's how we tailor the work — and why most generic "cyber security Brisbane" providers can't help homes at all.

Home Users

Secure your NBN router properly (most are wide open)
Protect kids with DNS-level content filtering & schedules
Stop smart cameras, bulbs, doorbells leaking data
Guest Wi-Fi for visitors and Airbnb stays
Secure work-from-home setups against employer audit
Family password manager + MFA on Apple ID, Microsoft, Google
Anti-scam education for parents and grandparents

Small Business (1–25 staff)

Separate staff, guest, and POS / EFTPOS networks
Microsoft 365 / Google Workspace hardening (MFA, DMARC)
Protect customer & supplier data (Privacy Act 1988)
BEC and invoice-fraud prevention
Remote worker VPN access (WireGuard / Tailscale)
Cyber insurance prerequisites (MFA, backups, training)
Essential 8 ML1 baseline for SMB tenders/grants

Geeks Brisbane vs Enterprise Cyber Security Firms

Most "cyber security Brisbane" providers (Sentrian, GPK Group, SafetyNet, Centra Networks, etc.) are excellent — for 50+ staff businesses. Here's how we differ, and when to pick which.

	Geeks Brisbane	Enterprise Cyber Firms
Helps home networks?	Yes	No
Helps 1–25 staff small business?	Yes — sweet spot	Usually 50+ staff
One-off audit & harden (no contract)	Yes — from $149	Rarely

Network & Internet Security FAQs

How do I know if my Brisbane home network is actually secure?

Most home networks in Brisbane have at least 3–5 unfixed gaps — default NBN router passwords, outdated firmware, weak Wi-Fi encryption, no guest network, IoT devices on the same SSID as your computer. If you've never had a security audit (or your "audit" was the install tech 4 years ago), there's a very high chance you have gaps. We can check the full 12-point list in about an hour and give you a written PDF showing exactly where you stand.

What's actually included in a network security audit?

A standard Geeks Brisbane network security audit covers: device inventory (everything on your network), router admin password and firmware, Wi-Fi encryption strength, SSID configuration, open port scan, DNS configuration, IoT device exposure, password manager and MFA status on key accounts (email, banking, Microsoft 365), and email security (SPF / DKIM / DMARC if it's a business). You get a written PDF report with findings ranked by risk level, and we fix the critical issues on the spot during the same visit.

Help — I think I've already been hacked. What do I do?

Call 1300 600 004 immediately — time matters when you've been compromised. Don't reset passwords from the compromised device. We can usually start an incident-response session within the hour. We'll help contain the breach (revoke active sessions, disable inbox rules, change passwords from a clean device), remove malware, reset every credential the attacker may have touched, audit sign-in logs, secure the network to prevent re-entry, and help you document the incident for cyber insurance or the bank.

Do you do business cyber security in Brisbane, or just home?

Both. We work with homes and with small businesses up to ~25 staff. For larger businesses with compliance requirements (ISO 27001, Essential 8 ML2/ML3, SOC monitoring, pentesting), we refer through to our sister brand Secure Nerds, who specialise in that segment. Both teams are based in Brisbane CBD and share the same parent company.

How much does network security cost in Brisbane?

A standard home network security audit and harden visit is $149 (inc GST), takes about an hour, and covers everything in our 12-point checklist. Small business audits (1–10 staff) are $295. Microsoft 365 hardening is $295. Incident response is $185/hr. Managed small business security retainers start at $390/month. Full pricing table is above on this page — no surprise upsells.

Can you do this remotely or do you need to come onsite?

Roughly half of network security work can be done remotely — Microsoft 365 hardening, MFA rollout, DNS filtering policies, password manager rollout, DMARC configuration, incident response on compromised cloud accounts. Router and physical Wi-Fi work usually needs an onsite visit (often the router admin page can only be reached from inside your own network). We'll tell you upfront which approach suits your situation — see our remote IT support page if you'd prefer to start remote.

What is "network hardening" and why does my router need it?

Network hardening means turning off everything you don't need and locking down what's left. On a typical NBN router that means: changing the admin password from "admin" / "password", disabling WPS, disabling remote-management, switching off UPnP for IoT, applying the latest firmware, choosing a strong WPA3 or WPA2-AES passphrase, hiding the admin interface from the WAN side, and separating guest devices onto their own network. Most NBN routers ship with all of these turned on insecurely by default because it makes the install tech's job faster.

Do I need a fancy firewall, or is the NBN router OK?

For most Brisbane homes and 1–10 staff small businesses, a properly-configured modern router (UniFi Express, ASUS, NetComm, Telstra Smart Modem 3) is plenty. You don't need to buy a $2,000 enterprise firewall. The big wins are configuration and updates, not new hardware. For 25+ staff or businesses with strict compliance, we'll spec a UniFi Dream Machine, Fortinet 40F or similar.

What is MFA and do I really need it on every account?

MFA = Multi-Factor Authentication. It means even if a hacker has your password, they can't log in without a second factor (a code from your phone, an authenticator app, or a hardware key). It's the single highest-leverage thing you can do for account security. We always enable MFA on, at minimum: email (Gmail, Microsoft 365, Apple ID), banking, MyGov, Xero/MYOB, and your password manager itself. Number-matching MFA (Microsoft / Google Authenticator) is preferred over SMS because SMS can be SIM-swapped.

Should I use Bitwarden, 1Password, or Apple Passwords?

Honest answer: any of them is dramatically better than "remembered passwords" or a sticky note. Apple Passwords is great if your whole household is on Apple. 1Password is the polished family/business choice (~A$5/month). Bitwarden is the free/cheap open-source choice with a generous free tier and a $30/year Premium. We help set up whichever one suits your situation, including recovery keys stored somewhere safe so you don't get locked out.

Can you protect my kids from inappropriate content online?

Yes — at the router/DNS level, which is much more effective than per-device parental-controls because it covers every device that joins your Wi-Fi (friends' phones, school iPads, gaming consoles, smart TVs). We typically set up NextDNS or Cloudflare 1.1.1.1 for Families with content categories and time-of-day schedules. Kids' devices on the home Wi-Fi automatically get filtered; visitors on the guest network do too. You stay in control of the policy.

Will network security make my Wi-Fi slower?

No — usually faster. Most home networks we audit are running on outdated firmware, congested 2.4GHz channels, with neighbours on the same SSID or smart bulbs hogging bandwidth. Updating firmware, switching channels, enabling WPA3, segregating IoT, and applying DNS filtering with a fast resolver like Cloudflare often improves real-world Wi-Fi and browsing speed. More on NBN Wi-Fi dropouts.

Do you help with cyber insurance pre-requisites?

Yes. Australian cyber insurance policies increasingly require: MFA on all admin accounts, regular off-network backups, endpoint protection on every device, staff phishing training, and a documented incident response plan. We tick all of these off and provide written evidence you can attach to your insurance application or renewal. Lots of Brisbane SMBs find their premium drops once they can show this paperwork.

Is "cyber security" the same as "network security" or "internet security"?

In practice — for homes and small businesses — yes, they're the same conversation. The semantic distinction is that "network security" focuses on the network layer (router, firewall, Wi-Fi, VPN), "internet security" focuses on what happens when you go out to the internet (DNS, browsing, downloads, scams), and "cyber security" is the umbrella term that also includes identity, cloud accounts, training, and incident response. We cover the lot in one visit.
