Choosing a venue booking system: 8 questions to ask vendors

Every venue booking system holds sensitive information, including guest names, payment details, dietary requirements and corporate contacts. Venues and event teams hand this data to a vendor and trust it will be handled properly.

When that trust is misplaced, the cost is high. The average data breach in the hospitality sector cost US$4.03 million in 2025, up from US$3.82 million the year before, according to IBM's Cost of a Data Breach Report.

Venue booking system security: 8 questions to ask your vendor

Before you trust a venue booking software vendor with guest and payment data, find out where that data is stored, how payments are secured, who can access it and what happens if something goes wrong. A vendor that takes security seriously should be able to answer these eight questions straight away:

1. Where is our data stored?

2. Is payment data PCI DSS compliant, and to what level?

3. Who at the vendor can access our guest data?

4. What happens to our data if we cancel the contract?

5. How is guest wifi separated from booking and admin systems?

6. What does the breach notification process look like?

7. Does the platform support role-based permissions for our own staff?

8. What third parties does the platform share data with?

1. Where is our data stored?

Your vendor should be able to name the country and data centre region where your data is held, and ideally let you choose it. Data residency decides which country's laws apply to your guest information, so ask for the physical location of the servers as well as the name of the cloud provider.

Corporate and government clients sometimes ask venues this directly during their own procurement checks, so it helps to have the answer ready. Some platforms let the venue choose its region at signup and host data separately by country instead of pooling it in one location. If a vendor can't answer quickly, they may not have mapped their own infrastructure closely enough to handle the harder questions that follow.

2. Is payment data PCI DSS compliant, and to what level?

Any vendor that processes card payments should be PCI DSS compliant and able to tell you which level they hold. Level 1 is the highest tier and applies to the largest transaction volumes. Requirements scale with volume, so ask which level applies to the vendor and when they were last audited.

Also ask how card details are handled during a transaction. The safer setups pass card data straight to a payment gateway over an encrypted connection, so it never touches the vendor's own database.

3. Who at the vendor can access our guest data?

Access to your guest data should be limited to vendor staff whose role requires it, with every access logged. Ask how quickly access is removed when someone leaves the company.

Risk from third parties is growing. Verizon's 2025 Data Breach Investigations Report found the share of breaches involving a third party doubled from 15% to 30%. It's also worth asking whether logins support two-factor authentication through an app or hardware key, since a leaked password on its own gives an attacker easy access.

4. What happens to our data if we cancel the contract?

You should be able to export your data on request, and the vendor should delete or archive it within a stated timeframe after cancellation. Get this in writing before you sign. Ask how long data is kept after cancellation and whether it's deleted or only archived, and make sure the contract lets you request a full export.

Ask how backups are handled day to day as well. A vendor that encrypts and rotates backups across separate data centres can recover your data cleanly if something goes wrong.

5. How is guest wifi separated from booking and admin systems?

Booking traffic should run on a separate network from guest wifi and be encrypted on every network it touches. Network setup is partly the venue's responsibility, but the vendor still has a role to play.

If staff use the booking platform on-site during events, ask whether the vendor offers guidance on keeping that traffic off the guest network, and whether the platform is safe to use over public wifi. iVvy requires TLS 1.2 encryption on every connection to the platform, so protection doesn't rely on individual staff members remembering to be careful.

6. What does the breach notification process look like?

A good vendor will have a documented breach notification timeline and share it without being asked. Find out how quickly they'd tell you if guest or payment data were exposed and what information they'd share. Then check that their timeline meets your own obligations to clients.

This matters most for smaller organisations. Verizon's 2025 report found ransomware was involved in 88% of breaches at small and medium-sized businesses, compared with 39% at large enterprises. A documented process is usually what makes the difference between a fast response and a slow one.

7. Does the platform support role-based permissions for our own staff?

Look for permissions your own administrators can set by role and switch off instantly. An audit log lets you check who did what after the fact.

Venues often have high seasonal turnover, with casual staff brought on for wedding season and contractors who come and go. Some platforms let venue administrators manage these controls directly, down to IP restrictions and automatic timeouts on inactive sessions, so changes don't need a support ticket.

8. What third parties does the platform share data with?

Ask for the full list of sub-processors and what data each one receives. Also ask how you'll be told if that list changes. Booking systems usually connect to several other tools, such as payment processors and CRMs, and each connection is another place where something could go wrong.

How to tell if a vendor has done the work

A vendor that takes security seriously will have written answers to these questions ready, usually in a security overview or trust document. If a sales rep has to improvise on the call, ask for the answers in writing before you go any further.
