Prices for a website security audit range from nothing to five figures, which makes the question hard to answer at a glance. Here's what sits behind those numbers, and how to pick the right level for a small business.
What you're actually paying for
Security "audit" covers a wide spectrum, and the price tracks how much human expertise is involved:
- Free automated scanners — run a URL, get a raw report. Useful for a first look, but no prioritisation, context or plain-English explanation.
- Focused small-business audits (~$100–$500) — automated checks plus human review, delivered as a readable report with a fix list. This is the sweet spot for most small sites.
- Manual penetration tests (low thousands and up) — a specialist actively tries to exploit your site. Thorough and appropriate for larger or high-risk applications, but overkill (and unaffordable) for a typical brochure or small e-commerce site.
- Ongoing monitoring / retainers — recurring fees for continuous scanning and alerts, on top of the initial audit.
What changes the price
- Automated vs manual. Human testing time is the single biggest cost driver.
- Scope. A single marketing site is cheaper to assess than a large app with logins, payments and integrations.
- Depth. A configuration and headers review costs far less than exploit-based testing.
- Remediation. Some audits stop at findings; others include fix guidance or a re-check afterwards.
Cheap vs expensive: how to choose
The trap at both ends is spending money in the wrong place. A free scan you can't interpret rarely leads to fixes, so the risk stays. A multi-thousand-dollar penetration test is excellent but wasted on a five-page small-business site that's simply missing standard headers. For most small businesses, the highest return comes from a focused, human-reviewed audit that tells you — in plain English — exactly what's wrong and what to fix first.

People also ask
How much does a website security audit cost?
From free (automated scanners) to several thousand dollars for a full manual penetration test. Focused small-business audits typically run about $100–$500 one-time. Sleak Check Audit is a flat $300.
Is a website security audit worth it?
For most small businesses, yes — the one-time cost is small next to a breach's cost in lost trust, downtime, remediation and potential penalties. An audit turns unknown risk into a clear action list.
What's the difference between a security scan and a penetration test?
A scan is largely automated and flags known issues; a penetration test is a manual, in-depth attempt to exploit weaknesses, done by a specialist at much higher cost. Many small sites are well served by a thorough, human-reviewed scan-based audit.
Are free website security checkers any good?
They're a useful starting point but return raw output with no prioritisation or plain-English explanation, and miss context. A paid audit interprets the results and tells you what to fix first.
