Healthcare has become one of the most targeted sectors for cyberattacks globally. The reason is straightforward: medical records contain everything an identity thief needs — name, date of birth, contact details, insurance information, financial data — in a single file. And historically, healthcare organisations have invested far less in cybersecurity than the value of the data they hold warrants.

If you run a practice, a clinic, or a health-tech platform, your digital security posture is not an IT question. It is a clinical ethics question. Your patients trusted you with their most sensitive information. Protecting it is part of your duty of care.

The Most Common Attack Vectors in Healthcare

Phishing emails remain the leading entry point for healthcare breaches. A convincingly formatted email that appears to come from a known contact — a lab, a pharmacy, a referral partner — can compromise an entire network if a staff member clicks a link and enters credentials.

Unsecured endpoints — personal devices used to access patient records, routers with default passwords, unpatched software — create entry points that attackers scan for systematically. Every device that touches patient data is a potential vulnerability.

Weak access controls — shared login credentials, passwords that were set years ago and never changed, accounts that remain active after a staff member has left — are responsible for a significant proportion of breaches that are never publicly attributed to external attack.

The Baseline Every Practice Should Have in Place

Multi-factor authentication on every account that accesses patient data. This single measure blocks the overwhelming majority of credential-based attacks.

Regular, tested backups stored offsite. Not backups that exist — backups that have been restored successfully in a test environment. The difference is significant.

A clear policy on personal device use — what is permitted, what is not, and how to access practice systems safely when working outside the clinic.

Annual staff training that goes beyond a policy document. Simulation-based phishing tests that show staff exactly what an attack looks like before they encounter a real one.

The Question to Ask Yourself Now

If your practice experienced a data breach tomorrow, could you tell every affected patient exactly what information was exposed and when? If the answer is no, your current systems do not meet the standard your patients deserve.
