Your Guide to Restaurant Cybersecurity in 2026

Restaurant cybersecurity is how you protect your restaurant's payments, data, devices, and accounts from scams and attacks. It goes far beyond being a simple IT issue: a fake invoice, a hijacked payroll account, or a locked office computer can all cost you money and pull your team away from guests.

This guide covers the biggest threats restaurants face, the warning signs to watch for, and practical steps your team can take, plus a checklist to work through.

Key takeaways: restaurant cybersecurity

• Restaurant cybersecurity protects payments, data, devices, and accounts, not just the POS.

• Most attacks start with a message. Phishing topped FBI cybercrime reports in 2025.

• Turn on multi-factor authentication (MFA) for email, banking, and payroll first.

• Confirm vendor bank changes by calling a number on file. Confirm payroll changes either in your system or in person.

• Train staff at onboarding and regularly after, not just once a year.

What is restaurant cybersecurity?

Restaurant cybersecurity is the collection of tools, habits, and policies that protect a restaurant’s payments, guest and employee data, devices, and online accounts from cyberattacks and fraud. It covers far more than POS: it also includes email, payroll, vendor payments, Wi-Fi, your website, and more.

Cyberattack vs. data breach: what’s the difference?

A cyberattack is an attempt to gain unauthorized access to a system or its data, or to disrupt it. A data breach is when that attempt succeeds, and confidential information is accessed or taken.

Not every attack becomes a breach. But when guest or employee personal information is exposed, you might need to notify the people impacted.

Why are restaurants vulnerable to cyber threats?

Restaurants are vulnerable to cyber threats because they handle a lot of payments and personal data, rely on many connected tools and vendors, and move fast. Each of those creates openings.

• Card payments all day. Restaurants process card payments on every shift, and payment data is valuable to criminals.

• Numerous connected tools and vendors. Online ordering, delivery apps, payroll, and loyalty programs each add another way in. If one of them is breached or poorly secured, your data can be exposed too.

• Steady vendor payments. Regular invoices across numerous vendors make a fake invoice or payment request easier to slip in.

• High turnover. New staff and frequent access changes make consistent training and access control harder.

• A fast pace. Busy shifts are when restaurants do their best work, and scammers know a quick approval can be easier to get mid-rush.

• Lots of devices. Handhelds, kiosks, card readers, and office computers all need to be secured.

What restaurant data can hackers steal?

Hackers can steal guest payment and contact information, employee personal and banking details, and even business data and proprietary information. It’s important to remember that marketing and loyalty lists, HR files, and back office records should all be protected against cyberattacks.

How can a cyberattack affect a restaurant?

A cyberattack can cost a restaurant money; it can interrupt or halt service, and it can damage the trust a restaurant has spent time building with its guests. 

• Lost money. Diverted payments, fraud losses, and recovery costs can add up quickly.

• Interrupted service. Locked systems can stop orders, payments, and payroll. In a 2026 survey of restaurant chain leaders, 68% said they lose more than $1,000 per hour when POS or ordering systems fail during a peak rush.

• Lost guest trust. Guests expect you to protect their payment and personal information, and a breach can make customers think twice before ordering online or coming back. 

• Lost business data. Data that is locked or stolen in a ransomware attack isn’t always returned, even if you pay the ransom. Recipes, sales history, and employee records can be gone for good.

• Fines and notification costs. A payment card breach can bring penalties and fines, and you might need to notify impacted guests and employees.

• Time away from the business. Recovery pulls owners and managers away from running service.

The impact of a cyberattack can last far beyond the attack itself. It's important to know what to watch for and how to protect yourself against an attack, starting with the most common threats below.

What are the biggest cybersecurity threats to restaurants?

The most common cybersecurity threats to restaurants include phishing, fake vendor invoices, payroll scams, hijacked accounts, weak passwords, card skimming and payment fraud, and ransomware. Many attacks don’t start with a hacker breaking in—they start with a fake invoice, a text from a “coworker,” or a call from someone posing as tech support.

Phishing emails, texts, and calls

Phishing is when a scammer poses as someone you trust to get a password, a payment, or a click on a harmful link. It can come by email, text, social media, or phone. Phishing attacks were the most-reported cybercrime to the FBI in 2025. 

What it looks like: 

• A fake delivery app email, saying your payouts are on hold until you log in

• A text from the “owner” asking a manager for a login code

• A caller says they’re from your internet provider and need remote access to the office computer to “fix” an issue.

Warning signs:

• You’re pressured to act right away.

• The sender’s email address, phone number, or link is slightly off.

• You’re asked to give a password, a login code, or a payment.

• A request for remote access

• A request for payment by gift card, cryptocurrency, or wire.

How to reduce risk:

• Never share your login credentials, no matter who asks.

• Turn on multi-factor authentication (MFA) for email, banking, and payroll tools.

• Don’t click on links or phone numbers in a suspicious message. Go directly to the company’s website and call the vendor’s number you already have on file.

• Don’t give remote access or payment to anyone who contacted you first.

• Ask your staff to report anything suspicious, even if they already clicked on it.

• Cover phishing in your training manual and new hire onboarding.

Fake vendor emails and invoice scams

Fake vendor emails and invoice scams, also called business email compromise (BEC), happen when scammers pose as a vendor or the restaurant’s owner to get you to pay the wrong account. According to the FBI, business email compromise led to more than $3 billion in reported losses in 2025. 

What it looks like: 

• Your “produce supplier” emails you with new bank account details for this week’s payment.

• A “vendor” sends an invoice for a supply order you never placed, and it gets paid with the rest of the week’s bills.

• The “owner” asks the general manager to pay an invoice — and to keep it quiet.

Warning signs:

• New bank account details sent by email or text, instead of your normal process

• An email address with one letter changed

• A sense of urgency or secrecy

• Anything outside the vendor’s usual pattern: unexpected refund requests, a new way to pay, or invoices off their normal schedule

How to reduce the risk:

• Confirm any banking changes by calling the vendor number you already have on file – the one on a fraudulent invoice might belong to the attacker. 

• Require two people to sign off before releasing large payments, and give any out-of-cycle payment an extra review.

• Establish a waiting period after any request to change account details, so there’s time to verify it before money goes out.

• Write these safeguards into your restaurant SOP. 

Did money already go out? If yes, you can still call your bank to request a recall. You can also file a report with the Internet Crime Complaint Center.

Payroll and direct deposit scams

A payroll or deposit scam involves criminals either posing as employees to get others to change the payroll direct deposit information, or stealing an employee’s payroll login credentials and changing the details themselves. With turnover being a prevalent part of the restaurant industry, these requests can be especially difficult to notice among frequent new hires and onboarding. 

What it looks like:

• On payroll day, the GM gets an email from a “line cook” asking to update their bank account information.

• An employee clicks on a fake search ad for your payroll site and enters their login credentials on the fake site.

Warning signs:

• A request for updated bank info by email or text, instead of your regular process

• A change requested right before payday

• A new account that points to a prepaid card

How to reduce the risk:

• Only accept bank or direct deposit changes through your payroll system or in person

• Turn on MFA for payroll accounts

• Skip the fake search ads — have your employees bookmark the payroll login page instead. 

• Spell out this process in your employee handbook.

Hijacked business accounts (email, bank, social media, delivery apps)

An account takeover happens when a criminal gets into one of your business accounts — usually with a stolen or guessed password. Once they’re in, they can redirect payouts, send other scams from your accounts, or lock you out completely. 

What it looks like:

• Your delivery app payouts start going to a bank account you don’t recognize.

• Your restaurant’s social media account posts a fake giveaway, and your login no longer works.

Warning signs: 

• A sudden flood of spam, which can be used to bury real security alerts

• Login alerts or password reset emails — when you haven’t requested any changes to your login

• Bank details, settings, or contact info changed without your knowledge

How to reduce the risk:

• Turn on MFA for every account that offers it, especially email and banking accounts.

• Use a different password for each account so a leak in one account doesn’t impact the rest.

• Keep a list of every business account and who has access to it. Remove people when they leave or no longer need access (like they’ve changed roles). 

• Use a business email you control for account recovery purposes, and secure that inbox before also securing others.

Weak passwords and shared access

Weak, reused, or shared passwords make it easier for criminals to get into your restaurant’s systems. In busy restaurants, it can be tempting to share one login for the office computer or vendor portals, but a uniform login makes it hard to know who made a change. 

Loose access also makes it easier for former staff to keep logging in, or for an untrained employee to make a genuine mistake with guest data.

What it looks like:

• One login for the office computer that every manager uses

• Using the same password for email, payroll, and the supplier portal

• Keeping passwords written on a sticky note in the back office

• A former manager still being able to log in to systems even after they’ve left

Warning signs:

• You can’t tell who made a change, because everyone uses the same login and account.

• Unusual voids, refunds, or discounts all tied to one login

How to reduce the risk:

• Turn on MFA wherever it’s offered.

• Use long passwords that don’t include common phrases or personal details like your name or date of birth.

• Give each person their own login credentials.

• Remove credentials and access to systems as soon as someone leaves.

• Give each employee access to only what their role needs. Review permissions whenever someone changes roles.

• Use a password manager to create and store unique passwords.

A restaurant POS that delivers unique employee logins and role-based permissions can help limit who has access to what systems. With Toast, each employee gets their own login and only the permissions their role needs. Those same permissions carry over to the Toast Now app, and Toast Reporting helps you spot unusual activity, like voids or refunds tied to one login. 

Card skimming and payment fraud

Card skimming is when criminals attach a hidden device to a card reader to steal card data. Payment fraud also includes malware planted on payment systems and stolen cards used to place online orders.

What it looks like:

• A card reader at the host stand has a loose or bulky piece that wasn’t there yesterday.

• A large online order comes in for pickup, but the cardholder disputes the charge a week later.

Warning signs:

• Card readers with loose parts, unfamiliar attachments, or signs they’ve been tampered with

• An unusual rise in chargebacks or in guest fraud complaints

• Online orders with mismatched names, unusual sizes, or rushed pickup requests

How to reduce the risk:

• Use a payment platform that encrypts card data and meets PCI DSS requirements.

• Accept chip and contactless payments whenever possible.

• Inspect card readers regularly. 

• Never write down or store full card numbers.

Ransomware attacks

Ransomware is malicious software that locks your files or systems, usually until you pay some sort of ransom. Some attackers also steal data like proprietary business information or customer data, and threaten to release it unless a ransom is paid. 

Ransomware usually gets in through the other threats we listed above, like a phishing email, stolen password, or outdated system. If an attack occurs, losing access to your systems can mean your entire operation comes to an immediate halt.

What it looks like

• The office computer shows a ransom note.

• You can’t open payroll, inventory files, online orders, or customer data.

• Your files suddenly have unfamiliar names or extensions.

Warning signs:

• Files you can’t open or that have been renamed

• Unexpected programs running, or your settings changed without your knowledge

• Security tools are turned off without explanation

How to reduce the risk:

• Turn on MFA whenever available.

• Keep your software updated to get the latest security patches.

• Back up important files offline or offsite (and test that you can restore them).

If you’re hit, you can disconnect the impacted devices and report it to the Internet Crime Complaint Center. Talk to law enforcement and an attorney before paying — making payments to sanctioned groups can actually create legal risks for you. 

Paying the ransom after a ransomware attack doesn’t always guarantee that you’ll get your data back, but the steps above can help reduce your risk of an attack being successful in the first place.

Summary: restaurant cybersecurity threats at a glance

These are common examples, not a complete list of every threat a restaurant may face.

Restaurant cybersecurity best practices: how to reduce your risk of a data breach

Restaurant cybersecurity best practices include training your team, limiting access, securing devices and networks, controlling vendor access, protecting payments, and keeping a written cybersecurity policy. No system can guarantee you’ll never experience an attack, but building security into how you already onboard staff, pay vendors, and run payroll can make your restaurant a harder target.

Use a cybersecurity framework

A cybersecurity framework is a structured way to make sure nothing important gets skipped. The NIST Cybersecurity Framework (CSF) 2.0 groups cybersecurity into six functions:

Toast’s PLATE method covers the same ground as NIST in five steps, all built around how a restaurant actually runs. Each step lines up with one or more of the NIST functions (identified in parentheses), so use whichever method is easier for your team to implement and remember.

Train your team and limit access

Your staff is your first line of defense in preventing a cyber attack. Training also helps to avoid honest mistakes, like sharing a login or writing down a card number, from staff who simply didn’t know any better. 

A single training session won’t stick, especially with high turnover and frequent new hires. Plan to make cybersecurity training and access checks into an ongoing practice, not a once-a-year event.

• Give each person their own login. Limit access to only what their role needs, and remove access when someone leaves. 

• Make sure onboarding covers phishing, payment and payroll change requests, how to handle guest and employee data (like never writing down card numbers), and how to report something. 

• Refresh and revisit the training regularly.

• Ensure employees can make reports without blame so they feel confident speaking up quickly, even after a mistake.

Secure your devices, networks, and data

Securing your restaurant’s devices, networks, and data comes down to a few basics: MFA, a separate guest Wi-Fi network, automatic updates, encryption, and tested backups. Most are one-time setups with updates you can automate. 

If you don’t have IT help in-house, your internet provider or a managed IT provider can help:

• Turn on MFA for email, banking, payroll, delivery apps, social media, and your website and domain accounts. Watch for look-alike sites using your restaurant’s name.

• Keep guest Wi-Fi separate from POS devices and office computers. Change the router’s default password, turn on its firewall, and use WPA3 encryption (or WPA2 if WPA3 isn’t supported).

• Turn on automatic updates, and replace devices that no longer get security updates.  

• Use antivirus software and full-disk encryption on office computers, laptops, and tablets. 

• Shred paper records and wipe old devices before you dispose of them.

• Back up important files offline, offsite, or in secured cloud storage – and test that you can restore them.

Control vendor and app access

Every vendor and app you connect to your business can see some of your data — and each brings its own security practices (or lack thereof) with it. Even if your own safeguards are strong, a data breach with a vendor or an integration can still expose your restaurant, employee, or customer data.

• Keep a list of every vendor and connected app — and what each one can access in your systems.

• Before you choose a vendor, ask how they protect your data.

• Remove apps, integrations, and accounts you no longer use.

• Confirm any change to a vendor’s payment details by phone.

Using fewer, more connected tools means fewer systems and vendors to secure. Toast Websites connects to your POS, online ordering, and reservations — so guests can order and book on your own site, instead of through another vendor.

Protect payments at every point of sale

Card data moves through your card readers, your POS, and your online ordering — and each one needs protection:

• Choose a payment platform that encrypts card data and meets PCI DSS requirements.

• Give each employee their own POS login, and limit permissions by role.

• Review voids, refunds, and comps regularly.

• Keep card readers in view, and check them for tampering at open and close.

• Watch online orders for fraud signals, like mismatched names or unusually large orders.

Toast Payment Processing encrypts payment data from the moment a guest pays and uses real-time machine learning to monitor online orders for fraud. For the full breakdown, see 9 ways to protect your restaurant POS system.

Create a written cybersecurity policy

A written cybersecurity policy is a short document that spells out your restaurant’s security rules: who owns security, how payment changes get approved, and what to do first in an incident. When writing your cybersecurity policy, keep it short and cover things like:

• Who owns cybersecurity — and who to call if something goes wrong

• Rules for passwords, MFA, and access

• How payment, payroll, and vendor changes get approved

• When to review access, updates, and backups (like quarterly or when an employee leaves)

• The first steps to take during an incident

Add your new cybersecurity policy to your SOP and employee handbook, and remember to walk new hires through it during onboarding.

Restaurant cybersecurity checklist

Use this checklist to see where your restaurant is today. Then, add it to your SOP so it’s reviewed on a regular schedule.

Employee training

• New hires learn how to spot phishing and fake payment requests during onboarding

• Staff know who to tell when something looks wrong, and that they won't be blamed for reporting

• Training is refreshed regularly, not just once a year

Passwords and access

• Every employee has their own login, with no shared passwords

• MFA is turned on for email, banking, payroll, delivery apps, and social media

• Access is removed the day someone leaves, and updated when someone changes roles

• Staff use long passwords or a password manager

• Guest Wi-Fi is separate from POS devices and office computers

• The router's default admin password has been changed

• Remote management on the router is turned off unless you need it

Backups

• Important files are backed up offline or offsite

• You've tested restoring from a backup

Vendors and apps

• You have a list of every vendor and connected app, and what each can access

• Unused apps, integrations, and accounts have been removed

• Changes to vendor bank details are confirmed by calling the number on file, not the number on the request.

• Employee direct deposit change requests are only made through the payroll system, or in person.

• Large and out-of-cycle payments need two sign-offs

Payment security

• Card readers are inspected regularly for tampering

• No one writes down or stores full card numbers

• Your payment platform encrypts card data and meets PCI DSS requirements

Incident response

• You know who to call first: your bank and local law enforcement, then your payment processor or POS provider, insurer, and attorney

• Staff know what to do first if a device or account may be compromised

• You have a way to record what happened, like our incident reporting template

Website and online ordering

• MFA is turned on for your website, domain, and online ordering accounts

• You watch for look-alikes using your restaurant’s name

What should a restaurant do after a data breach?

After a data breach, a restaurant should contain the damage, call its bank and law enforcement, contact its payment processor, insurer, and attorney, document everything, notify anyone affected, and fix the cause. It’s important to act quickly, but you don’t have to act alone.

The steps below draw on the FTC’s Data Breach Response Guide and guidance from the FBI. 

1. Contain it. Disconnect any impacted devices from the internet, but don’t turn them off or wipe them (investigators might need them). Change passwords to any accounts that might be impacted.

2. Call your bank and law enforcement. If money went out, contact your bank right away and ask about potentially recalling the funds. Then, report it to your local law enforcement, and file a report with the Internet Crime Complaint Center.

3. Contact your partners. Call your payment processor or POS provider, your insurer, and your attorney.

4. Write everything down. Record what happened, when you noticed it, and what you've done since. 

5. Notify the right people. Depending on where your guests and employees live, you might be legally required to notify them after a breach. Talk to your attorney about what rules apply to you.

6. Fix the cause and learn from it. Close the gap that let your attackers in. Then, update your written cybersecurity policy, and retrain your team on what happened and how to avoid it happening again.

These aren’t steps you want to be figuring out for the first time during a breach — plan the protocols now so they’re ready if you ever need them. Add them to your SOP so everyone knows who to call and what to do first.

How Toast fits into your restaurant cybersecurity plan

Maintaining proper cybersecurity can become harder with every separate system you add to your stack. Each payment terminal, ordering app, or reporting tool is another vendor to keep track of — and each brings its own logins, permissions, and potential security vulnerabilities. 

Toast brings those pieces into one platform that’s built for restaurants, so you have fewer systems to secure and manage during a busy shift. That includes:

• Toast Payment Processing, a Level 1 PCI-compliant service provider that encrypts payment data from the moment a guest pays

• Tokenization, plus EMV and NFC hardware for card payments

• Role-based permissions, so each employee sees only what their job needs

• Reporting to review transaction activity

• Real-time machine-learning fraud monitoring for online orders

• Offline capabilities that allow you to continue taking card payments during an internet outage. 

• Toast Websites that automatically stay in sync with your menu, online ordering, and POS, so there’s one less separate system to manage

Fewer systems to manage, with security protections built in, means your team can stay focused on guests — not on juggling logins and vendors. Get a demo to see how Toast can support your restaurant.

Restaurant cybersecurity FAQs

Are restaurants common targets for cyberattacks?

Yes. A 2024 payment fraud report found that restaurants remained a leading source of payment card breaches. Restaurants are also targeted by scams aimed at email, payroll, and vendor payments — not just the POS.

Do small restaurants need to worry about cybersecurity?

Yes. Small restaurants can be targets for cyberattacks because there are fewer people to check payments and accounts, and busy shifts make quick approvals easy. One convincing email can lead to a fake invoice being paid, a paycheck diverted, or systems locked. Business email compromise alone led to more than $3 billion in reported losses to the FBI in 2025.

How often should restaurant employees receive cybersecurity training?

During onboarding, then regularly after that. CISA recommends repeating training at regular intervals so employees learn about the latest scams, and warns that once-a-year training alone isn't enough. Short refreshers during pre-shift meetings are an easy way to keep it top of mind.

What's the first thing a restaurant should do to improve cybersecurity?

Turn on multi-factor authentication (MFA) for your business email, bank, and payroll accounts. Those accounts are common targets, and MFA means a stolen password alone isn't enough to get in. Then, work through the checklist above.

What should I do if I send money to a scammer?

Call your bank right away and ask them to recall the payment, then file a report with the Internet Crime Complaint Center and your local law enforcement. 

How can restaurants protect customer payment information?

Use a payment platform that encrypts card data and meets PCI DSS requirements, accept chip and contactless payments when you can, and never write down or store full card numbers. For more detail, see our guide to restaurant POS security.
