The importance of data security, and how you can ensure your guest data is securely stored

As big chain hotels suffer data breaches of sensitive customer credit card information, the importance of data security is once again in the spotlight. The most recent breach suffered by some Hyatt locations noted that malicious software code had been inserted into certain hotel information technology systems.

Data breaches affect businesses of all sizes, in a multitude of industries. It is however, more present in the accommodation industry due to the high turnover of staff, and outdated legacy systems. Not only does a data breach impact your customer’s data, it will also impact the loyalty of your customers and can lead to loss of future sales.

With other hotel groups also announcing data breaches this year, reducing the risk of becoming a target should be at the forefront of every hotelier’s mind. There are some simple measures you can take to protect your business data, here are a few you can easily implement:


Having secure passwords is an easy way to strengthen your security. Ensure your staff changes their passwords every few months. You can introduce password policies for your staff to encourage good habits. While this is a small change coupled with the other tips below, you can deter any potential breaches.

Individual accounts

Another security measure you can implement is to have unique logins (user accounts) for each staff member. This ensures you can trace any actions around customer booking data.


Anti-virus and anti-malware software are indispensable tools to protecting your data. This should be a standard across all computers that are accessing customer data. When it comes to data security, taking preventions will ultimately prove more beneficial.

Back-up your data

Preno’s hotel management system always has a secure backup of your Preno data. You should however make a copy of your non-Preno data, in case your computer crashes.

Writing down credit cards, printing numbers, or storing full numbers leave your business open to a breach.
