Every security guide says "scan regularly." None of them tell you what that actually means for a small business.
Here's a real answer.
The honest baseline: monthly is the minimum, weekly is better
If you're running a website that collects any user data — even just email signups — monthly scanning is the floor. Not because of some arbitrary best practice, but because the threat landscape changes that fast. New vulnerability templates get published constantly. A misconfiguration that wasn't flagged last month might be a known attack vector today.
Weekly scanning is practical for most SMEs now because automated tools have made it cheap. There's no reason to scan less frequently than your attackers are probing you.
When you need to scan immediately (outside your schedule)
After any code deployment
After adding a third-party integration or plugin
After a team member leaves (access hygiene audit)
After any public disclosure of a vulnerability in software you use
Before any audit or compliance review
These aren't scheduled — they're triggered. Your scan programme should account for both.
What scanning actually tells you
A vulnerability scan tells you what's exposed and reachable on your website right now. It's not a penetration test (that's a human trying to exploit what's found). It's not a code audit (that's reviewing your source). It's the fastest way to get a current picture of your attack surface — what ports are open, what headers are missing, what known CVEs match your stack.
For UAE businesses specifically, this matters because UAE PDPL treats regular scanning as part of your "appropriate technical measures" obligation. Your scan history is your compliance evidence.
The real answer on frequency
E-commerce or fintech handling payments: weekly minimum, daily if you can
SaaS with user accounts and data: weekly
Informational site with contact forms: monthly
Static marketing site with no user data: quarterly
The determining factor is how much personal data you process and how often your codebase changes. More data + more deployments = more frequent scanning.
Monarc automates this — scheduled scans, severity-rated findings, PDPL-mapped compliance reports. Join the waitlist if you want early access.
