Wix Security Checklist for Small Business Owners

Wix's platform is genuinely secure on the back end — but "Wix is secure" and "my Wix site is secure" are two different claims, and the gap between them is entirely your responsibility. Wix patches servers, issues free SSL certificates, and runs a PCI-compliant payment system. It does not stop someone from guessing your password, does not vet every app you install from the App Market, and does not decide how much customer data your contact form quietly collects.

Who this is for: you run a small business, agency, or side project on Wix and you've never done a real security pass on it. What you'll get: a plain checklist of exactly what Wix already covers, what's on you, and the settings to check today — no code required.

What Wix Handles vs. What You Handle

Wix is a fully hosted (SaaS) platform, which means you never touch a server — Wix's own team owns patching, uptime, and infrastructure defense. That's a real advantage over self-hosted WordPress, where the site owner is on the hook for every plugin update. But "hosted" only covers the plumbing, not what you build on top of it.

Wix documents its platform-level commitments in its Trust Center — worth a five-minute read if you want the vendor's own claims, not just this checklist.

The Wix Security Checklist

Work down this list once, then revisit it every few months or whenever staff changes.

1. Turn on two-step verification. On wix.com, go to your account profile (top-right icon) → Settings → Security, and enable two-step verification. This is the single highest-impact change you can make — CISA recommends multi-factor authentication as one of the most effective defenses against account takeover, because it stops a stolen or guessed password from being enough on its own.
2. Use a unique password, not a memorized one. Reused passwords are the number one reason small-business accounts get taken over — one breach at an unrelated site hands over your Wix login too. Use a password manager to generate and store a unique one. NIST's password guidance actually recommends long, unique passphrases over the old "8 characters, one symbol, one number" rule — length and uniqueness beat complexity.
3. Audit who has access. Go to Dashboard → Settings → Roles & Permissions and review every collaborator. Remove former employees, freelancers, and agencies you no longer work with. Each person with editor access is a password that can be phished.
4. Review every installed app. Go to Dashboard → Apps → Manage Apps. For each one, ask: do we still use this, and what data does it request access to (site content, contacts, orders)? Delete anything unused — an abandoned app is still a live door into your site's data.
5. Check your forms for data you don't need. Open Dashboard → Contacts and each Forms submission setting. If you're collecting phone numbers, addresses, or IDs you don't actually use, remove those fields. Less collected data means less to leak if anything ever does go wrong.
6. Know where form submissions actually go. Wix Forms can email submissions, store them in Contacts, or both. Make sure whoever's inbox receives them isn't a shared/legacy account nobody checks or secures.
7. Set up account recovery correctly. Confirm the recovery email and phone number on your Wix account are current — if you're ever locked out or need to prove account ownership after a compromise, this is how you get back in.
8. Know how to use Site History. In the Wix Editor, the History icon lets you roll back to a previous saved version. If a page ever gets defaced or an app makes an unwanted change, this is your undo button — know where it is before you need it.
9. If you use a custom domain for email, check your DNS records. SPF, DKIM, and DMARC records stop attackers from sending phishing emails that look like they're from your domain. Run your domain through Bug Circuit's free email spoofing checker to see if these are set up correctly.
10. Review embedded third-party scripts. Chat widgets, ad pixels, and analytics tools you've pasted into your site's custom code (Dashboard → Settings → Custom Code) can read page data and, in some cases, form input. Remove any you no longer actively use — this mirrors the general risk OWASP flags around vulnerable and outdated third-party components: code you didn't write is still code you're responsible for.
11. Turn on notifications for account changes. Wix can alert you by email when your password or account details change — make sure that email actually reaches someone who'll notice.
12. Check what your site sends to browsers. Even on a hosted platform, you can inspect your live site's response headers with a tool like Bug Circuit's security headers checker to understand your baseline — useful context if you ever add custom code or a headless setup on top of Wix.

The Overlooked Risk: Third-Party Apps

Most Wix compromises small business owners run into don't come from Wix's core platform being broken — they come from what's installed on top of it. The Wix App Market reviews apps before listing them, but an app's behavior after installation (what it does with the data it can access, whether its own backend gets breached later) isn't something Wix continuously polices for you.

Treat every app install like handing someone a key: ask what it needs access to, whether you still use it, and whether the developer is still actively maintaining it. If an app hasn't been updated in over a year and you don't remember installing it, remove it.

Is Wix Secure Enough for My Business?

For most small businesses — a services site, a local shop, a simple online store — yes, Wix's infrastructure is a reasonable, well-maintained foundation. You're not managing a server, and you're not the one responsible for patching a zero-day in the platform's core code.

Where it gets more nuanced is scale and sensitivity: if you're collecting health information, processing large volumes of payment data outside Wix Payments, or need to answer a client's security questionnaire with specifics, "we use Wix" isn't a complete answer — you'll also need to show your side of the checklist above is handled. Our guide on manual vs. automated penetration testing explains the difference if a client or partner is asking for proof.

Signs Your Wix Site May Already Be Compromised

Wix's own protections mean full server compromise is rare, but account-level compromise still happens. Watch for:

• Pages, products, or blog posts you didn't create
• Apps installed that no one on your team recognizes
• Customers reporting spam or phishing emails that look like they're from your domain
• Unexpected redirects when visitors land on your site
• A password reset email you didn't request

If you see any of these, change your password immediately, turn on 2FA if it isn't already on, and check our guide on what to do if your website's been hacked. If you're unsure whether something you're seeing is actually a problem, our free website security check gives you a fast yes/no on critical issues, no card required.

Key Takeaways

• Wix secures the infrastructure (servers, SSL, DDoS, payments); you're still responsible for passwords, access, apps, forms, and embedded scripts.
• Turning on two-step verification is the single highest-impact five-minute fix available to you.
• Audit installed apps and collaborator access at least twice a year — remove what you don't actively use.
• Minimize what your forms collect, and confirm where submissions actually go.
• "Wix is secure" isn't the same claim as "my Wix site is configured securely" — this checklist closes that gap.

Running this checklist yourself covers the basics well. If you want a second set of eyes — someone who actually clicks through your app list, tests your forms, and checks your public-facing configuration the way an attacker would — that's exactly what a $49 manual audit from Bug Circuit does: a real person reviews your site and hands you a written report with fixes, not just a scan.
