Dental Cybersecurity: Why Your Practice Is a Prime Target

Dental Cybersecurity: Why Your Practice Is a Prime Target

News and Blogs

6th November 2025

Cyberattacks on dental practices are rising sharply. While 43% of UK businesses reported experiencing a cyber breach or attack in 2025, dental clinics face even greater risk due to the sensitive nature of patient data and often outdated systems. As practices increasingly adopt digital records, cloud-based patient data and remote access tools, they become lucrative targets for cybercriminals. The good news? With proactive cybersecurity solutions from Microminder, dental practices can safeguard sensitive data, maintain patient trust and avoid costly downtime or penalties.

Key Takeaways

• Dental practices are increasingly targeted due to valuable patient data and outdated systems.
• Common threats include ransomware, phishing, and data breaches.
•  A single breach can cost a practice upwards of £35,000 in fines, recovery, and reputational damage.
• Proactive threat hunting and automated defences are essential for modern dental cybersecurity.
• Partnering with a specialist like Microminder ensures tailored protection for dental environments.

Why Are Dental Practices at Risk?

Dental practices are increasingly targeted by cybercriminals due to the high value of patient data and the prevalence of outdated systems. Patient records often contain a combination of medical history, financial details, and personal identifiers, all of which can be sold on the dark web. Many clinics also operate with limited IT support, which are highly sought after by attackers, making them more susceptible to breaches.

What Are the Most Common Cyber Threats in Dentistry?

Dental clinics face a range of cyber threats, including:

• Ransomware: Malicious software that locks access to files until a ransom is paid.
• Phishing: Fraudulent emails that trick staff into revealing credentials or clicking harmful links.
• Data Breaches: Unauthorised access to sensitive information, often due to weak passwords or unpatched software.
• Remote Access Risks: Poorly secured remote access can be exploited by attackers to gain unauthorised entry into practice systems and patient records.

These threats are not hypothetical, they’re happening regularly across the UK, with some practices facing recovery costs exceeding £35,000, including fines, remediation, and reputational damage.

How Can Dental Practices Strengthen Their Cyber Defences?

To protect against these threats, dental practices must adopt a proactive approach to cybersecurity. This includes:

• Proactive Threat Hunting: Continuously monitoring for suspicious activity before it escalates.
• Automated Defences: Using AI-driven tools to detect and neutralise threats in real time.
• Multi-Factor Authentication (MFA): Adding an extra layer of protection to login processes.
• Online Encrypted Backups: Ensuring patient data is securely stored and easily recoverable.
• Staff Training: Educating employees on cyber hygiene, as human error remains a leading cause of breaches.

These measures not only reduce risk but also demonstrate a commitment to patient safety and regulatory compliance.

What Role Does Remote Access Tools Play in Dental Cybersecurity?

Remote access tools are increasingly used in dental practices to enable flexible working and access to digital records. While convenient, these tools can introduce serious vulnerabilities if not properly secured:

• Outdated VPNs may lack encryption or patching, exposing sensitive data.
• Weak login credentials can allow unauthorised access to patient records and practice systems.
• Unmonitored remote sessions may be exploited by attackers to move laterally across the network.
• Misconfigured access controls can inadvertently grant staff or third parties more access than necessary.

Microminder’s cybersecurity solutions include secure remote access configurations, multi-factor authentication, and continuous monitoring — ensuring that off-site connectivity doesn’t become a backdoor for attackers.

What Happens If a Dental Practice Suffers a Breach?

The consequences of a breach extend far beyond IT recovery. Practices may face:

• Financial penalties under GDPR
• Loss of patient trust
• Operational downtime
• Legal action and reputational harm

In many cases, the total cost of a breach, including fines, remediation and lost revenue can exceed £35,000. Prevention is not just preferable –  it’s best practice.
