Your clients' ID numbers, tax files and payroll stay in the practice
An accounting or bookkeeping practice holds SA ID numbers, bank details, IRP5s and payroll exports for dozens of client companies, and clerks are bombarded with fake SARS eFiling and banking alerts every tax season. ZDNS protects the practice network with one router setting, from R499 a month for up to 10 people.
SARS eFiling & tax-refund phishing
During filing season, staff receive convincing emails asking them to "verify the practice's SARS eFiling profile" or view an urgent IT34 assessment. ZDNS blocks domains on Google's phishing list before the fake login page loads.
Payroll & EMP501 identity leaks
Payroll runs and EMP201/EMP501 spreadsheets contain hundreds of employee SA ID numbers and bank account numbers. ZDNS verifies the 13-digit SA ID check digit and blocks lookups trying to smuggle those numbers out.
Fake CIPC, UIF uFiling & bank alerts
Phishing links disguised as CIPC annual-return notices or business banking verification prompts try to steal credentials or drop remote-access trojans on bookkeepers' PCs; ZDNS stops known bad domains at the router.
Built for small practices (R499/mo)
The Small Office plan covers a practice of up to 10 people for R499 a month (or R50 per seat in packs of 25 for larger firms), with plain-English weekly reports.
How it plays out
A six-person tax and payroll practice. Illustrative, not a real customer.
- 1
During tax season a payroll clerk receives an email asking her to "re-authenticate the practice's SARS eFiling organisation profile".
- 2
The link leads to a lookalike domain on Google's list of suspected phishing sites.
- 3
ZDNS answers "does not exist", so the fake eFiling login page never loads and no client tax profiles are exposed.
- 4
The block appears on the dashboard, and the weekly report shows when it happened and which lookup was stopped.

Good to know
ZDNS checks every lookup for SA ID numbers, bank account numbers and payroll details, plus scrambled codes that malware uses to smuggle data. Here is what to expect.
An extra layer
ZDNS does not replace email filtering, two-factor authentication or antivirus. It stops known phishing sites and personal data leaving through DNS, and tells you when it happens.
Small practices
Up to 10 people: the Small Office plan, R499 a month. Larger practices: R50 a seat in packs of 25.
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.
