Practical Cyber Security for Home, Mobile and Small Business
Technology should make life easier without exposing more of your personal information than necessary.
I help individuals, families and small businesses improve the security of their phones, computers, networks and online accounts using sensible, practical solutions without unnecessary complexity.
Most People Do Not Need Enterprise Cyber Security
They do need secure passwords, sensible network configuration, updated devices, protected accounts and a clear understanding of what is connected to their network.
Modern homes and small businesses can contain dozens of internet-connected devices, including computers, phones, cameras, televisions, smart devices, storage systems and cloud-connected equipment.
My approach is to identify the important risks, fix what genuinely matters and keep the solution understandable and maintainable.
Good Security Starts With
- Secure devices
- Strong account protection
- Updated software and firmware
- Properly configured networks
- Protected backups
- Reduced unnecessary internet exposure
- Knowing what is connected and why
Security That Fits the Way You Actually Use Technology
From a single privacy-hardened phone through to securing an entire home network or small business environment.
GrapheneOS Phones
Privacy-hardened Google Pixel phones configured with GrapheneOS for people who want greater control over their mobile security and personal information.
- GrapheneOS installation
- Privacy configuration
- Sandboxed Google Play if required
- Secure messaging
- VPN setup
- Password manager
- Application permission review
Home Network Hardening
Review and improve the security of your router, Wi-Fi, Windows computers, Android devices, cameras and smart home equipment.
- Router security
- Wi-Fi configuration
- Firewall review
- Smart device security
- Camera and NVR security
- Account and password review
- Backup and recovery review
Small Business Hardening
Practical cyber security for small businesses that need better protection without the cost or complexity of enterprise IT.
- Router and firewall review
- Windows security
- User account security
- Multi-factor authentication
- Email security
- Backup strategy
- Remote access review
Internet security is no longer just about putting antivirus software on a computer.
Your router, phones, smart televisions, security cameras, cloud accounts, doorbells, storage devices and home automation systems can all become part of your security footprint.
Small businesses have the same problem, often with additional risks created by shared computers, customer information, email accounts, remote access and business-critical data.
Computers and laptops
Phones and tablets
Routers and Wi-Fi
Cameras and NVRs
Cloud-connected devices
Email and online accounts
Backups and stored information
A More Private Smartphone
Modern smartphones contain an extraordinary amount of personal information. They know where we go, who we communicate with, what accounts we use and often have access to our photos, microphone, camera and financial applications.
GrapheneOS provides a hardened Android environment with stronger security and extensive privacy controls while remaining practical for everyday use.
Compatible Google Pixel phones can be professionally configured with the applications and services you need without simply accepting every default setting provided by the manufacturer.

What Should Be Checked?
- Router administrator security
- Router firmware
- Wi-Fi encryption
- Connected devices
- Guest networks
- Port forwarding and remote access
- Security cameras
- Smart home equipment
- Windows computers
- Android devices
- Backups
Do You Know What is Connected to Your Wi-Fi?
Most people could name their phones, computers and televisions. The full list is often much longer.
Security cameras, smart speakers, doorbells, appliances, switches, streaming devices and forgotten equipment may all still be connected to the network.
A home network hardening review identifies those devices, checks the router and Wi-Fi configuration and reduces unnecessary exposure without making the system difficult to use.
Read the Home Network GuideA small business may not have an internal IT department, but it can still hold valuable information and depend heavily on its technology.
Email accounts, Windows computers, customer information, cloud storage, accounting systems and backups can all become business-critical.
Security does not need to mean expensive enterprise hardware or complicated systems. For many small businesses, the biggest improvements come from securing accounts, correctly configuring existing equipment, keeping devices updated and making sure important data can be recovered.
A dedicated small business security service is being developed, but individual business environments can already be assessed and hardened according to their actual requirements.
Secure routers and firewalls
Protect Windows computers
Review administrator accounts
Enable multi-factor authentication
Improve email security
Secure remote access
Make sure backups actually work
Fix the Important Things First
Security should be based on the real risks and the way the technology is actually being used.
Identify
Understand the devices, accounts, networks and services that need to be protected.
Prioritise
Focus on weaknesses that create meaningful risk rather than changing things simply for the sake of it.
Harden
Improve configuration, accounts, networks, software and devices using practical security controls.
Keep it Usable
Security that makes technology impossible to use usually gets disabled. The final system still needs to work for you.
You Can Do a Lot of This Yourself
Many security improvements are straightforward. Change default passwords, install updates, enable multi-factor authentication and remove equipment you no longer use.
The difficulty starts when changes affect other systems. Router settings can affect cameras, smart devices, remote access and network storage. Business environments can become more complicated again.
The guides on this site are designed to help you understand what should be checked. If you reach the point where you would rather have someone work through it properly, that is where I can help.
Consider a Security Review If
- You do not know what is connected to your network
- Your router has not been checked for years
- You have multiple cameras or smart devices
- You use remote access
- You store important information at home
- Your backups have never been tested
- Your small business has grown without a security plan
Privacy and Cyber Security Questions
Simple answers to common questions about improving security at home, on your phone and in a small business.
1. What is cyber security hardening?
Security hardening means reducing unnecessary weaknesses in a device, network or account. This can include installing updates, removing unnecessary access, strengthening passwords, enabling multi-factor authentication and correctly configuring security settings.
2. Do home users really need network security?
Yes. Modern homes often contain many internet-connected devices. Keeping the router, Wi-Fi, computers, phones and smart devices securely configured reduces unnecessary risk and helps protect personal information.
3. What is a privacy-hardened phone?
A privacy-hardened phone is configured to reduce unnecessary data exposure and provide stronger control over applications and permissions. One option is GrapheneOS running on a compatible Google Pixel device.
4. Does a small business need expensive cyber security?
Not necessarily. Many small businesses can significantly improve their security by correctly configuring existing equipment, protecting user accounts, using multi-factor authentication, keeping systems updated and maintaining reliable backups.
5. Can you make a computer or network completely secure?
No system connected to people, networks or the internet can be guaranteed completely secure. Good cyber security is about reducing avoidable risk, limiting exposure, protecting important information and making recovery possible if something does go wrong.
Whether you want a privacy-hardened phone, a safer home network or help improving the security of a small business, we can start with the systems you already have and work from there.
