Website audit vs full security pentest: what's the difference?
By the LaunchSafer team ·
An automated website audit and a penetration test answer different questions. What each covers, what neither does, and when you need which.
"Is my website secure?" can mean two very different things, and the two kinds of check that answer it are often confused. Here's how an automated website audit (like LaunchSafer) differs from a full penetration test.
What an automated website audit does
An audit looks at what any visitor can see from the outside, without logging in or trying to break anything. It checks configuration and common problems quickly and repeatably:
- HTTPS, certificate validity and HTTP-to-HTTPS redirects
- Security headers such as HSTS, CSP and clickjacking protection
- Mixed content and cookie flags
- Secret keys accidentally published in page source
- Plus SEO, performance, accessibility and UX, which a security test doesn't cover
It takes minutes, costs little or nothing, and you can run it before every launch and after every big change.
What a penetration test does
A penetration test (pentest) is a security specialist actively trying to break in, with your permission. They test the things an audit deliberately doesn't touch:
- Login, password reset and session handling
- Access control: can one customer see another's data?
- Injection flaws such as SQL injection and cross-site scripting in forms and APIs
- Business logic: can someone skip a payment step or change a price?
- Sometimes the servers, cloud setup and internal network as well
A good pentest takes days, is done by a person, and is usually priced in the thousands.
Side by side
- Who does it: an audit is automated; a pentest is done by a security specialist.
- What it touches: an audit reads public pages only; a pentest actively probes, including logged-in areas.
- Time: an audit takes minutes; a pentest takes days to weeks.
- How often: run an audit continuously; commission a pentest yearly or after major changes.
- What it finds: an audit finds misconfiguration and missing protections; a pentest finds exploitable flaws in how your app works.
Which do you need?
Most small sites and early-stage products should start with an audit: it catches the common, easy-to-fix problems for free. You need a pentest when you handle sensitive data, take payments in your own code, sell to companies that ask for one in security reviews, or need it for compliance.
They are complementary. Fixing everything an audit finds first means you're not paying a specialist to point out missing headers.
Start with the free part
Run a free website health check or the security headers checker. LaunchSafer's scans are non-intrusive and safe to run against production; they are not a penetration test.
