If your client doesn't want to upgrade their security measures, then there must be a good reason behind it. Unless, they just don't have time to do so. A good communication is key here. Ask your client the reason why they don't want to update. Educate them about the pros and cons, and if they have some worries or concerns, see if it is within your capacity to get rid of the concerns. Give them assurance and make them feel that updating is the best thing to do. Also if you have a access to your client's data, one thing you can do for your client is to make back ups for them (, unless it is resource intensive to do it for free) Then tell them you're willing to do this but only for a limited time, so that they will also feel the urgency.

I address client concerns by educating them on the risks and benefits of security updates, offering incremental changes to avoid overwhelm, and implementing strict access controls to minimize breach risks.

In the last years, I have also often had situations where customers did not want to implement certain security measures. In this case, it was important for me to understand why not. The most common answer was that they weren't sure how the feature worked. Practical examples and intensive demos of the functionalities help to convince customers.

A security update is a critical tool to mitigate potential risks like data breaches, malware infections, and unauthorized access by patching vulnerabilities in software, essentially closing "holes" that hackers could exploit, thereby protecting your systems and sensitive information; neglecting updates can leave you exposed to significant threats like ransomware, phishing attacks, and data theft, while applying updates regularly can significantly improve your system's overall security and minimize the chances of these attacks occurring
