Most WordPress site owners don't know their site is infected until Google flags it, their host suspends them, or a customer reports something strange. By then, the damage is done — lost traffic, lost revenue, lost trust.
That's why we offer a free WordPress security scan with a simple promise: if we don't find anything to fix, you don't pay.
What We Check in a Free Security Audit
This isn't a surface-level scan. We run the same checks our paying customers get:
1. File Integrity Analysis
We compare every file on your WordPress installation against the official versions from WordPress.org:
- WordPress core files — has anyone modified wp-login.php, wp-includes files, or wp-admin scripts?
- Plugin files — do your installed plugins match what's published on WordPress.org?
- Unexpected files — are there PHP files hiding in your uploads folder, or suspicious files in your theme directory?
2. Malware Signature Detection
We scan your entire file tree for known malware patterns:
- Encoded backdoors — base64_decode, eval, gzinflate chains that hide malicious code
- Web shells — WSO Shell, FilesMan, C99, and similar attacker tools
- SEO spam injectors — code that injects hidden links or redirects for search engines
- Card skimmers — JavaScript that intercepts payment forms on WooCommerce checkout pages
3. Database Inspection
Your database is often where the real damage hides:
- Rogue administrator accounts — accounts created by attackers for persistent access
- Injected scripts in post content — JavaScript injected into your pages and posts
- Suspicious scheduled tasks — WordPress cron jobs that re-infect your site after cleanup
- Modified site URL or home URL — a redirect attack at the database level
4. Configuration & Server Checks
- File permissions — are critical files world-writable?
- PHP version — are you running an unsupported PHP version with known vulnerabilities?
- SSL certificate — is it valid and properly configured?
- Security headers — X-Frame-Options, Content-Security-Policy, HSTS
- .htaccess integrity — has it been modified with redirect rules?
5. Plugin & Theme Risk Assessment
- Outdated plugins with known CVEs — cross-referenced against the NIST vulnerability database
- Abandoned plugins — no updates in 2+ years
- Nulled or pirated themes — a leading source of backdoors
How the "No Fix, No Fee" Process Works
- Submit your site URL through our emergency recovery form or contact us directly
- We run a full scan — typically takes 15–30 minutes depending on site size
- You receive a detailed report covering every finding, categorised by severity
- If your site is clean — you get the report for free, no charge, no obligation
- If we find issues — we quote a fixed price for the cleanup, and you decide whether to proceed
There's no pressure, no subscription required, and no hidden costs.
What Happens If We Find Malware?
If the scan reveals infections, we provide:
- A complete findings report with every infected file, every backdoor location, and every database injection documented
- A fixed-price cleanup quote — not hourly billing, not "it depends". A clear number before we start
- A cleanup guarantee — if the same malware comes back within 30 days, we re-clean for free
Typical cleanup scope and pricing
| Severity | What's involved | Typical turnaround |
|---|---|---|
| Light infection (SEO spam, single backdoor) | Core cleanup + hardening | Same day |
| Medium infection (multiple backdoors, database injections) | Full file + database cleanup | 1–2 days |
| Heavy infection (rootkit, hosting-level compromise) | Server-level cleanup + migration | 2–3 days |
Why "No Fix, No Fee" Makes Sense
We're confident enough in our scanning to guarantee the results. Here's why:
- We use the same engine as our WordPress plugin — WO Security Shield's file integrity scanner, malware signature database, and vulnerability checker
- False positives are rare — our scanner is tuned to minimise noise; when we flag something, it's real
- Clean sites are good for our reputation too — every clean report proves the scanner works
How to Get Your Free Scan
Three ways to start:
- Use our online scanner at wosecurity.com — instant external scan that checks SSL, headers, and common indicators
- Install WO Security Shield (free plugin) on your WordPress site for a deep internal scan
- Request a manual audit through our emergency form — we'll review your site personally
Your site security shouldn't be a mystery. Let's find out where you stand.
