Why Unpatched Software Is One of the Biggest Risks Facing Your Practice
A staff member at your clinic opens their laptop on a Monday morning and everything looks normal. What they cannot see is that a piece of software running quietly in the background has a known security flaw - one that has been documented for years - and no one has ever fixed it. That flaw is a door. And it is unlocked.
This is not a hypothetical. Research consistently shows that a large proportion of successful cyberattacks exploit vulnerabilities that already had a fix available. The patch existed. It just was not applied. For a healthcare practice or legal firm handling sensitive client information, that kind of oversight can lead to a serious breach - one that triggers obligations under the NZ Privacy Act 2020 and potentially a notification to the Office of the Privacy Commissioner.
The problem is that software is never finished. Every update a developer releases can introduce new weaknesses alongside the improvements. Hackers look for those weaknesses and write code to exploit them. The software maker releases a patch. But if your systems are not kept current, the patch sits unused while the exposure remains. Most small practices do not have someone whose job it is to track this. So gaps accumulate quietly over time. Understanding the ways hackers get into business accounts makes it clear why staying current matters so much.
Managing this properly - what the industry calls vulnerability management - is a structured process, not a one-off task. It starts with knowing exactly what devices and software are running on your network. Computers, phones, tablets, cloud services, and anything else that connects to your systems all need to be included. From there, a proper assessment scans those systems against known vulnerability databases to find what is out of date or exposed. The findings are ranked by severity, with the most critical issues addressed first. Fixes are applied, confirmed, and documented. Then the process repeats on a regular schedule, because new vulnerabilities are identified constantly.
When this is handled well, the day-to-day experience for your team does not change much. Software updates happen in the background. Security gaps get closed before anyone can exploit them. And if something did go wrong, there is a clear record of what was assessed and when - which matters enormously if you are ever asked to demonstrate that you took reasonable steps to protect client data. You can see how this plays out in practice in our professional services IT support case study.
The documentation piece is often overlooked. Keeping a log of assessments and remediation steps is not just good practice - it is important evidence in the event of a breach, and it supports any compliance reporting your practice may need to do. It also makes each future assessment faster, because you are building on a clear record rather than starting from scratch. Pairing this with strong passwords and multi-factor authentication gives your practice a much stronger security foundation overall.
Most practice managers and business owners are not going to run vulnerability assessments themselves - nor should they. This is work that requires specialist tools and the knowledge to interpret the results. What matters is that it gets done regularly, by someone who knows what they are looking at, as part of a managed IT support arrangement that treats security as an ongoing responsibility rather than an occasional job.
