About Us

At KNA Security, we are a family-owned West Australian security company specialising in high-quality security doors and security screens in Perth. We established our business more than 14 years ago with a simple goal: to provide security solutions we would confidently install in our own homes.

Today, we continue to protect homeowners across Perth’s northern suburbs,  with professionally manufactured and installed home security systems built for strength, durability and long-term performance.

If you are searching for security doors in Perth, an Invisi-Gard dealer near you, or a licensed security installer in Western Australia, we are proud to be a trusted local choice.

As a WA-owned and operated company, we understand the specific conditions and security requirements of Perth homes. From coastal environments to contemporary home designs, we tailor our security doors and screens to suit Western Australian properties.

Over the past decade, we have secured thousands of homes across Perth. Many of our clients contact us after seeing our installations on neighbouring homes, a referral we value highly.

When you contact KNA Security, you deal directly with our local Perth team, rather than a call centre or interstate supplier.

We operate in full compliance with Western Australia’s security licensing requirements. We hold:

• One Security Agent’s Licence (44340)
• Three Security Installer Licences
• Three Security Consultant Licences

This means we are fully insured, police-cleared and authorised to both install and provide professional advice on residential security products.

For homeowners looking for a licensed security door installer in Perth, this provides genuine peace of mind. We meet state regulatory standards and stand firmly behind our workmanship.

We are proud to be an authorised dealer of Invisi-Gard security doors and screens in Perth. Invisi-Gard products are tested to Australian Standards and engineered to provide genuine protection against forced entry.
As an authorised supplier, we provide:

• Genuine Invisi-Gard products
• Installation completed to the manufacturer’s specifications
• Security systems that are legally rated and exceed Australian Standards, not just decorative screens

Many homeowners choose Invisi-Gard because it offers strength, airflow and modern design in one solution. It protects your home without compromising light or appearance.

If you are searching for an Invisi-Gard dealer in Perth, we provide expert supply, advice and professional installation.

One of the key differences at KNA Security is that we manufacture our security doors and screens right here in Perth. Very few local companies continue to do this.

By manufacturing locally, we maintain strict control over quality and ensure every door and screen is custom-built to suit the exact measurements of your home.

Local production allows us to provide:

• Custom-built security doors for Perth homes
• Consistent quality control
• Faster turnaround times
• Components designed for WA conditions

We are also actively involved in refining and developing our own security door components, allowing us to continually improve durability and performance.

We welcome customers to visit our factory in Neerabup to view our security doors and screens in person. Seeing the frame construction, mesh systems and locking mechanisms firsthand often makes the decision easier and more informed.

We believe in transparency and take pride in what we build. When you choose KNA Security, you are choosing a local Perth company focused on quality, compliance and long-term protection.
