How Much Does a Website Security Audit Cost in 2026? (Real Pricing)

What a website security audit actually costs

If you have searched for "website security audit cost," you have probably found prices ranging from free to $50,000 — with almost no explanation of why. The gap is real, and it comes down to one thing: how the work is performed. This guide breaks down every tier so you can match spend to risk without overpaying.

Here is the short version, then we will unpack each option:

Free online scanners: $0 — shallow, noisy, no remediation guidance.
Automated audit services: $99 to $499 one-time — broad coverage, plain-English fixes, fast turnaround.
Annual SaaS scanners: $1,200 to $12,000 / year — continuous monitoring, dashboards.
Manual penetration test: $5,000 to $30,000+ per engagement — deep, human-led, slow.

Tier 1: Free vulnerability scanners ($0)

Free tools like browser header checkers or open-source scanners are a fine starting point, but they share three problems: they only test a sliver of your attack surface, they produce false positives that waste developer time, and they hand you raw output with no prioritisation. You are left asking, "Okay—but what do I actually fix first?"

Free is the right budget for hobby projects. For anything that handles customer data or revenue, it is a false economy. We compare the categories in detail in our guide to a free vulnerability scanner vs. a paid security audit.

Tier 2: Automated audit services ($99–$499 one-time)

This is the fastest-growing category and the sweet spot for most small and mid-sized businesses. A good automated audit runs the same classes of checks a consultant would start with — OWASP Top 10 indicators, email authentication, TLS configuration, security headers, exposed ports, subdomain takeover risk, and credential exposure — then delivers a prioritised report in hours, not weeks.

Exarlo sits here: a one-time $149 automated security audit with 60+ public-surface checks, plain-English remediation, a polished PDF, and a 48-hour delivery guarantee. The value proposition is simple — you get most of the signal of a junior pentester's first pass, at roughly 1% of the cost, with nothing to install.

Tier 3: Continuous SaaS scanners ($1,200–$12,000 / year)

Subscription scanners re-test your surface on a schedule and trend results over time. This is genuinely valuable once you ship frequently — your external attack surface changes with every deploy. The trade-offs are cost, dashboard fatigue, and the fact that you still need someone to action the findings. For teams that have outgrown one-time audits, this is the natural next step.

Tier 4: Manual penetration testing ($5,000–$30,000+)

A manual pentest puts skilled humans against your application, including authenticated flows and business logic that no automated tool can fully understand. It is the gold standard for compliance attestations and high-stakes systems. It is also slow (2–6 weeks), expensive, and a point-in-time snapshot that is stale the moment you ship again. We explain when you truly need one in why penetration testing alone is not enough and automated vs. manual penetration testing.

What drives the price up

Scope: number of domains, apps, and APIs.
Depth: passive/public-only vs. authenticated and exploit-confirmed.
Human time: the single biggest cost multiplier.
Compliance paperwork: SOC 2 / PCI attestation letters add cost.
Remediation support: retesting after fixes is often billed separately.

How to choose without overspending

Start cheap and broad. Run a one-time automated audit first. It surfaces the obvious, exploitable issues — the ones attackers find with the same tools — for a couple hundred dollars.
Fix the criticals, then re-scan. Most reports reveal that 80% of your risk lives in a handful of misconfigurations.
Escalate deliberately. Only commission a manual pentest once your public surface is clean and you have a specific compliance or high-value target that demands human testing.

For most businesses, the honest answer to "how much should I spend?" is: a few hundred dollars, today, to find out where you actually stand — then invest further based on what the report reveals. See exactly what is included in our website security audit checklist, or run your audit now.
