The Biggest Cybersecurity Risks Facing Veterinary Clinics, and the Layered Safeguards That Keep Care Running

Written by Joseph Axne | Oct 26, 2026, 9:48:13 PM

A veterinary practice runs on its technology. The PIMS holds every patient record, appointment, invoice and client contact. Imaging, lab equipment, payment terminals and phones all depend on the network. When an attack takes those systems down, the impact isn't just an IT problem. Appointments stall, records are out of reach, and your team is back to paper while patients are waiting.

Veterinary clinics are attractive targets for the same reasons they are busy: they hold client names, addresses and payment information, they can't afford to be down, and most don't have a dedicated security team on staff. The good news is that the attacks we see most often are predictable, and so are the safeguards that stop them.

Why No Single Tool Is Enough: Layered Security and a Real Framework

There is no one product that makes a practice "secure." Antivirus alone won't stop a staff member from approving a fraudulent login. A firewall won't help if backups were never tested. Real protection comes from layers, so that when one defense is bypassed, the next one catches it:

  • People: staff who can recognize a phishing email or a scam phone call
  • Accounts: multi-factor authentication and limited administrative rights
  • Devices: patched, supported computers with modern endpoint protection
  • Network: a private network kept separate from guest and personal devices
  • Data: protected backups that can actually be restored
  • Response: a plan for what happens when something gets through

Layers only work if they're complete and measurable. That's where a security framework comes in. Recognized frameworks and control sets, such as the CIS Critical Security Controls or the NIST Cybersecurity Framework, turn "good security" into a defined list of safeguards you can check against, instead of relying on one person's opinion or whichever product was purchased last.

Whoever manages your practice's technology, whether an in-house team or an outside IT provider, should be aligning their work to a framework like this, and should be able to show you clearly where your practice stands against it and what's left to address. If they can't, that's worth a conversation.

Below are the biggest risks we see in veterinary clinics and the safeguard layer that addresses each one.

1. Phishing and Email Account Takeover

What it looks like: An email that appears to come from a vendor, a lab, Microsoft, or even the practice owner asks someone to "review a document" or "verify your account." Once a password is entered on a fake page, the attacker can read email, send invoices with changed bank details, or use the account to launch a larger attack.

The safeguards:

  • Multi-factor authentication (MFA) on email and every cloud application, including your PIMS if it's cloud-based
  • Email filtering that blocks malicious links and attachments before they reach the inbox
  • Ongoing security awareness training, so staff know what to look for and how to report it

2. Ransomware

What it looks like: Files and systems are encrypted and a ransom note appears. Your PIMS, imaging and shared files become unusable, and in many cases the attackers also copy client data before encrypting it.

The safeguards:

  • Modern endpoint detection and response that looks for attacker behavior, not just known viruses. (We've written about what this kind of platform finds that traditional antivirus misses.)
  • Prompt patching of Windows and applications
  • Limited admin rights (see the next risk), which keeps one bad click from becoming a practice-wide outage
  • Protected backups that ransomware can't reach

3. Full Admin Rights on Everyday Accounts (High Risk)

What it looks like: The accounts staff use every day to check email, browse the web and work in the PIMS have full administrator rights on the computer. It's often set up that way for convenience, so nobody has to call for help to install a program or a printer driver.

Why it's high risk: Anything that runs under that account inherits those rights. A malicious attachment, a fake browser update, or a remote access tool installed by a scammer can install software, disable security protections and spread across the network, all without a single additional prompt. Removing admin rights from everyday accounts is one of the simplest, highest-impact changes a practice can make.

The safeguards:

  • Everyday user accounts run as standard (non-admin) users
  • Administrative access is reserved for separate, dedicated admin accounts used only when needed
  • MFA on administrative access
  • A simple process for staff to request software or changes, so the restriction doesn't slow the practice down

4. Unpatched and End-of-Life Computers

What it looks like: The workstation in radiology that "can't be touched," a server running an operating system the manufacturer no longer supports, or computers that haven't installed updates in months. Attackers actively look for these known, unpatched weaknesses.

The safeguards:

  • Automated, monitored patching for operating systems and applications
  • An accurate inventory of every computer and the software running on it
  • A replacement roadmap, so end-of-life systems are retired on a planned budget instead of in an emergency
  • Working with imaging and equipment vendors when a device truly can't be updated, so it can be protected in other ways

5. Guest and Personal Devices on the Private Network

What it looks like: Clients in the waiting room, visiting reps, or staff members' personal phones are all connected to the same Wi-Fi network as the PIMS server, workstations and imaging equipment.

Most veterinary practices don't need a complicated network design. The line that matters most is between your private network and everyone else's devices. You have no control over what's on a client's phone, a visitor's laptop, or even a staff member's personal device, and none of them should be able to reach the systems that hold your patient and client data.

The safeguards:

  • A separate, isolated guest Wi-Fi network for clients and visitors
  • Staff personal phones and devices kept on the guest network, off the private network
  • Private Wi-Fi credentials known only to IT, not posted or shared with staff for personal use
  • Up-to-date, supported firewall and wireless equipment

6. Remote Access Tools (RATs)

What it looks like: Remote access tools let someone see and control a computer from anywhere. Your PIMS, imaging and equipment vendors legitimately use them for support. Attackers use the exact same tools. Over time, a practice can collect several of them, installed by different vendors over the years, some always on and unattended, and nobody is sure who still has access.

Scammers also call practices pretending to be a vendor, a bank or a phone company and talk staff into installing a remote access tool "to fix the problem." Once it's installed, they're inside. (We shared a real scam attempt against our own team that followed this pattern.)

The safeguards:

  • An approved list of remote access tools, with everything else detected and removed
  • A current list of which vendors have remote access, and to what
  • Vendor sessions that are approved, logged, and protected with MFA wherever possible
  • A clear rule for staff: never install remote access software at a caller's request. Hang up and contact IT.

7. Backups That Have Never Been Tested

What it looks like: Backups are "running," but nobody has restored from them in months or years. During a ransomware attack or server failure, the practice discovers the backups were incomplete, out of date, or encrypted along with everything else.

The safeguards:

  • Automated backups of the PIMS, file shares and critical systems
  • A protected, isolated copy that ransomware and attackers can't reach or delete
  • Routine test restores, so you know the backups work and how long recovery actually takes

Keeping Care Running When Something Does Get Through

Layers reduce risk; they don't eliminate it. The practices that recover fastest are the ones that decided ahead of time what they would do. That means:

  • Knowing who to call, and who in the practice makes decisions during an incident
  • A simple way for staff to report something suspicious right away, without fear of blame
  • Downtime procedures: how you'll check in patients, record treatment and take payment if the PIMS is unavailable
  • Contact information for your PIMS vendor, insurance carrier and IT partner, kept somewhere other than the systems that might be down

A Quick Self-Check for Practice Owners and Managers

If you can't confidently answer "yes" to each of these, it's worth a closer look:

  1. Is whoever manages our IT aligning to a recognized security framework, and can they show us where we stand?
  2. Is MFA turned on for email and every cloud application we use?
  3. Do our everyday user accounts run without administrator rights?
  4. Are all of our computers on a supported operating system and getting updates automatically?
  5. Do we have endpoint protection that monitors for attacker behavior, not just viruses?
  6. Are clients, visitors and staff personal phones kept off our private network?
  7. Do we know every remote access tool installed in the practice, and who can use it?
  8. Have we successfully restored from backup in the last few months?
  9. Does our team know what to do, and who to call, if the PIMS goes down?

Frequently Asked Questions

What is the biggest cybersecurity risk for a veterinary clinic?

For most practices, it starts with email. Phishing and stolen passwords are the most common way attackers get in, and from there they can commit invoice fraud or launch ransomware. MFA, email filtering and staff training address that entry point directly.

Does a veterinary practice need a cybersecurity framework?

Yes. A framework turns security from a collection of products into a defined, measurable set of safeguards. Widely used options include the CIS Critical Security Controls and the NIST Cybersecurity Framework. The specific choice matters less than having one: your IT team or provider should be aligning to a recognized framework and reporting your progress against it.

Does HIPAA apply to veterinary records?

HIPAA generally does not cover veterinary patient records. Practices still hold sensitive client information, including names, addresses and payment card data, and are subject to payment card security requirements and state privacy and breach-notification laws. A breach also carries real costs in downtime and client trust.

Why shouldn't staff use admin accounts for everyday work?

Anything that runs under an administrator account inherits those rights. If a staff member opens a malicious attachment while logged in as an admin, the malware can install itself, disable protections and spread. Standard user accounts contain the damage.

How often should a veterinary practice test its backups?

Regularly, not just once. Routine test restores confirm the backups are complete and tell you how long recovery takes, which is the number that matters when your PIMS is down.

Security That Supports Patient Care

Cybersecurity isn't about buying the most tools. It's about putting the right layers in place, measuring them against a recognized standard, and keeping your team focused on patients instead of outages. That's the thinking behind our IT Standards of Care, which give practice owners and managers a clear view of how their computers and network measure up, and a roadmap for closing any gaps.
