In the world of business, data is everything. For Filters Plus WA, a Perth-based company specialising in filtration solutions for automotive, racing, industrial, and heavy machinery, their most valuable asset was not just their product catalogue, but their extensive Filtration Cross-Reference Database. This database, containing a little over One Million cross-reference records, allows customers to quickly match filters across brands, OEM and competitor brand part numbers. This intellectual property has been built over 20 years with countless hours of meticulous work, and it is unlike anything else in the industry. Sure, some manufacturers have their own cross references, but this database is independent of any brand and is added to on a daily basis.
However, the very system that powered their online success had become a growing liability. Their existing WordPress plugin, which managed this cross-reference system, was outdated, insecure, and exposed to constant online attacks. After years of frustration, wasted hours, and mounting security concerns, Filters Plus WA partnered with Velocity WA, a Perth-based custom software developer, to rebuild their plugin from the ground up.
The result was a new, secure, and highly efficient custom solution that not only protected the company’s data but also improved the way their team managed and expanded their database. This case study explores how Custom Software solutions can transform the way businesses operate and safeguard their most valuable digital assets.
The Challenge: An Outdated Plugin and Endless Security Threats
Filters Plus WA’s original WordPress plugin had been built many years earlier by a developer who was no longer in business. While it had served the company well for a time, it lacked one critical feature: security.
The plugin controlled the company’s Filtration Cross Reference Database, which housed their most valuable intellectual property. Over time, it became clear that this data was being targeted by bots and hackers attempting to scrape and steal the information.
The plugin had no security measures, meaning that anyone (or anything) could query the database directly. As attacks increased, the Filters Plus team found themselves wasting hours every week manually banning IP addresses and trying to fend off malicious activity.
In addition to these security issues, the plugin was outdated in several ways:
-
It had no rate-limiting or spam protection, allowing thousands of automated requests per hour.
-
The data management interface was clunky and difficult for staff to update.
-
There was no logging or monitoring, so identifying unusual activity was impossible without another 3rd party security plugin.
-
The system lacked modern import and export functionality, making it time-consuming to add new data in bulk.
This situation left Filters Plus WA in a difficult position. Their most valuable business system was both mission-critical and dangerously vulnerable.
Enter Velocity WA: A Perth-Based Custom Software Solution
Recognising the urgency of the problem, Filters Plus WA turned to Velocity WA, a Perth-based software development firm known for its Custom Software Solutions in Perth.
Velocity WA’s team quickly realised that patching the existing system would not be enough. The underlying plugin architecture was outdated and insecure, meaning any temporary fix would simply delay inevitable future issues. Instead, they proposed a complete rebuild: a new, custom-built WordPress plugin designed to replicate all existing functionality while adding modern performance, scalability, and security.
This new plugin would:
-
Preserve the existing cross-reference search and management features.
-
Include advanced, built-in security features.
-
Offer improved data management tools for staff.
-
Be future-proofed for new features and database growth.
The Filters Plus WA team agreed, and development began.
Building the New Plugin: Security, Performance, and Flexibility
1. Replicating the Core Features
The first step was to ensure the new plugin provided all the functionality of the old system. Velocity WA reverse-engineered the existing plugin to understand how it processed cross-reference data, displayed results, integrated with the WordPress database, and displayed the correct product to purchase.
They then built a new structure from scratch, using modern coding standards and optimised database queries. This ensured faster loading times, cleaner data handling, and compatibility with the latest versions of WordPress and PHP.
The new plugin included:
-
A fully searchable cross-reference database for customers.
-
A backend management system for staff to update, edit, and review records.
-
Compatibility with Filters Plus WA’s eCommerce product catalogue (WooCommerce)
2. Advanced Security Features
The most important improvement was security. Velocity WA implemented several protective systems that effectively ended the company’s long battle with bot attacks. We will not list these out here to protect their system, but the new security features block bot attacks and stop overusage from people, too. The limiting rates are customisable by Filters Plus so they can take control of their own security.
These features stopped malicious bots in their tracks, protecting the database from exploitation and keeping Filters Plus WA’s proprietary information secure.
3. Scalability and Future-Proofing
Velocity WA built the new plugin with scalability in mind. The system can handle large volumes of data without slowing down, and it is structured so that new features can be added easily in the future.
This future-proof approach means that Filters Plus WA can continue building on their software investment rather than replacing it again in a few years.
The Results: Security, Efficiency, and Confidence
The impact of the new plugin was immediate. Within hours of deployment, the security issues that had plagued the business disappeared. The automated protection systems blocked malicious requests before they reached the database, freeing staff from the tedious task of banning IP addresses.
The company regained complete confidence in the safety of its most valuable intellectual property. Moreover, the new management tools allowed the Filters Plus WA team to:
-
Upload and manage data faster.
-
Track missing references and customer demand.
-
Ensure new entries were accurate and relevant.
The plugin became more than just a security upgrade. It became a strategic business tool that empowered Filters Plus WA to operate more efficiently and intelligently.
Beyond the Plugin: A Continuing Partnership
The success of this project marked the beginning of an ongoing relationship between Filters Plus WA and Velocity WA. Impressed with the professionalism, technical expertise, and problem-solving approach of the Velocity team, Filters Plus engaged them to identify other areas of the business where custom software could streamline operations.
Velocity WA is now working closely with Filters Plus WA to:
-
Improve internal workflows through automation.
-
Integrate third-party tools with their website and inventory systems.
-
Develop analytics dashboards to monitor sales and performance in real time.
This partnership highlights the long-term value of investing in custom software WA solutions rather than relying on generic, one-size-fits-all tools.
The collaboration between Filters Plus WA and Velocity WA is a perfect example of how Custom Software can protect, modernise, and empower a business. What began as a crisis over data security became an opportunity to innovate and streamline operations.
By rebuilding their WordPress plugin from the ground up, Velocity WA delivered a secure, efficient, and future-ready solution that now forms a vital part of Filters Plus WA’s success.
For Perth businesses still relying on outdated systems or unsupported software, this case study is a reminder that modernisation is not just about keeping up with technology. It is about taking control, safeguarding what matters, and unlocking new opportunities for growth.
Velocity WA’s expertise in custom software Perth development continues to help local businesses future-proof their systems and operate with confidence in an increasingly digital world.
