Protect patient ID numbers and reception PCs without slowing the front desk
Medical, dental and allied practices hold patient SA ID numbers, medical aid membership details and cell numbers on busy reception PCs looked after by an outside IT technician. ZDNS protects the practice network from one router setting, for R499 a month for up to 10 staff.
Medical aid & claim-switch phishing
Receptionists receive fake emails disguised as Discovery Health, GEMS, Medscheme or switching-house remittance queries. ZDNS blocks links on Google's list of suspected phishing and malware sites before they load.
Patient list theft before ransomware
When ransomware reaches a reception or billing PC, it often tries to copy patient SA ID numbers and mobile numbers out first to extort the practice. ZDNS recognises valid SA IDs and mobile numbers in DNS lookups and blocks them.
Fake pathology & referral links
Phishing emails posing as specialist referrals, X-ray links or lab reports try to plant data-stealing malware at the front desk; ZDNS blocks known malicious domains across every computer on the practice router.
Nothing installed on reception PCs
No agents to slow down billing or switching software. One router setting covers a practice of up to 10 people for R499 a month, starting in 7-day shadow mode with plain-English reports for you or your IT technician.
How it plays out
A three-doctor family practice. Illustrative, not a real customer.
- 1
Reception opens a fake "medical aid claim rejection & remittance" link that slips a data stealer onto the front-desk PC.
- 2
Before locking any files, the malware tries to copy patient SA ID numbers and cell numbers out inside DNS lookups.
- 3
ZDNS recognises valid 13-digit SA ID numbers and blocks the lookups, so the patient list does not leave the practice.
- 4
The practice manager and IT technician see the alert on the dashboard, trace the reception PC, and clean it.

Good to know
ZDNS checks every lookup for patient ID numbers and mobile numbers, plus scrambled codes that malware uses to smuggle data. Here is what to expect.
What ZDNS doesn't see
Only the domain names your network looks up. Not clinical notes, medical aid claims, emails or files, and lookups that pass are not stored.
Not everything is detectable
Data spelled out in letters or chopped into short pieces is only sometimes caught. ZDNS is an extra layer, not a replacement for backups and antivirus.
Nothing is blocked in week one
Every customer starts in shadow mode for about a week, sees what would be blocked, and whitelists anything they rely on before blocking starts.
Keep your patients' ID numbers where they belong
R50 a seat a month, from 25 seats. One router setting. Protected in shadow mode from day one.
