What is PCI scope?Your PCI scope involves anything in your business that processes, stores, or transmits cardholder data, and anything that can initiate a connection to any of the systems that handle cardholder data.
Put simply, any device, process, or employee that involves credit card data is in your PCI scope, which means you are responsible to make sure that card data is properly secure.
Some common devices included in PCI scope can be
- POS systems

Finding the scope in your businessThe first step to reducing scope is finding out all the places and ways your business could come into contact with cardholder data.
The key to determining your PCI scope is understanding how your business works.Some questions to ask yourself are:
- How do you record cardholder data?
- Where do you store the data?
- How do you manage your systems?
- How do you log into them?
- How do you backup your systems?
- How do you connect to get reports?
- How do you reset passwords?
There are often processes you don’t think of that could be included in your scope. For example, employees could be taking card numbers over the phone or receive emails with card information. There’s also power-outage procedures where card data may be manually taken down. Follow the paper trails in your business to make sure all card data is secured. Even if card data is 10 years old, it’s still in PCI scope.
Think about all elements on your system. Even if you believe something is out of scope, it may hold temporary files, log files, or back-ups with unencrypted data. Check your devices to make sure no hidden card data is lurking.
After you find your devices in scope, find everything that can communicate with them. If you have a server that handles cardholder data, think about what else connects with that server. Who has permission to access your card data and how do you transmit it?
Also think about how your employees interact with card data. Are they storing card data at their desks? Are they taking down credit card data over the phone? These types of issues need to be taken into account as well.
Tips to reducing your scopeOnce you’ve determined the scope in your business, it’s time to manage and reduce your scope. Here are some tips to reduce PCI scope.

Use limited access
Your janitor shouldn’t have the same access privileges as your accountant. Not all of your employees need access to cardholder data. By limiting access and having a hierarchy of employees who can handle card data, you reduce the amount of people interacting with the data. This boosts your security and makes PCI compliance a bit easier.

Outsource to third party
This may not work for every business, but if possible, it may be easier to outsource handling payments and card data to a third party. Examples include using tokens, or using business models like PayPal to ensure your company has minimal contact with cardholder data.
Keep in mind that if you do outsource your payment, you will still need to make sure the party you outsourced to is PCI compliant. You could still be held liable in the event of a data breach, should it be shown you didn’t make sure that party was compliant.
