Most website owners assume their site is secure — until it isn't. A breach, a malware injection, or a sudden blacklisting by Google tends to change that perspective fast. The good news is that you don't need a security consultant to find out where your defenses actually stand. A structured self-audit takes a few hours and can surface real gaps before attackers do.
This isn't about paranoia. It's about knowing what you have and what you're missing. Let's work through it systematically.
Start With the Basics: HTTPS and SSL
Open your site in a browser and check the address bar. Is there a padlock icon? Does your URL start with https://? If not, this is your first and most urgent fix.
HTTPS encrypts data between your visitors and your server. Without it, passwords, form submissions, and payment details can be intercepted in transit. Google also penalizes non-HTTPS sites in search rankings, so this has real business consequences too.
Even if you see the padlock, click it and check when the certificate expires. Expired SSL certificates break the padlock and show visitors a scary warning page. Most managed hosting environments handle certificate renewal automatically — but if yours doesn't, set a calendar reminder at least 30 days before expiry. For more details on how SSL certificates work, see our SSL overview.
Check Your Login Security
Weak login credentials are still one of the most common entry points for attackers. Go through these questions honestly:
- Are you using a unique password that isn't reused anywhere else?
- Is your password at least 16 characters, or generated by a password manager?
- Do you have two-factor authentication (2FA) enabled on your CMS, hosting panel, and domain registrar?
- Are there any admin accounts you've forgotten about — old developer logins, agency accounts from a previous vendor?
That last point catches a lot of people off guard. Go into your CMS user list and delete any account you can't identify or no longer need. Every extra account is another door into your site.
Review Your Software and Plugin Versions
Outdated software is the single most common cause of compromised websites. This is especially true for WordPress sites, where known vulnerabilities in old plugin versions are actively exploited within days of disclosure.
Check that your CMS core, themes, and plugins are all running their latest versions. If you see items that haven't been updated in months — or worse, plugins that are no longer maintained — treat them as security risks. Either find a maintained alternative or remove them entirely.
Don't just look at active plugins either. Deactivated plugins that are still installed can still contain exploitable code. If you're not using it, delete it.
Run a Malware Scan
You may already have malware on your site without knowing. Some infections are designed to be invisible to the site owner — they redirect mobile visitors to spam pages, inject hidden links into your content, or quietly harvest visitor data.
Several free tools can help you check:
- Sucuri SiteCheck — scans your public-facing pages for known malware signatures and blacklist status.
- Google Safe Browsing — visit transparencyreport.google.com/safe-browsing/search and enter your domain.
- VirusTotal — run your URL through dozens of security engines at once.
These tools only scan what's publicly visible. If you want to scan your actual server files, you'll need server-level access or a tool that your hosting provider supports. We've written more about protecting your site from modern threats if you want to go deeper on this.
Look at What's Sitting in Front of Your Site
Good website security protection doesn't just come from your application — it also comes from what sits in front of it. Ask yourself:
- Does your hosting environment include a firewall that filters malicious traffic at the server level?
- Is there a web application firewall (WAF) inspecting requests before they reach your application code?
- Is there any protection against volumetric attacks that could knock your site offline?
If you're not sure, ask your host directly. A WAF, for example, blocks common attack patterns like SQL injection and cross-site scripting before they ever reach your database. If your host doesn't include one, you can add a third-party service like Cloudflare's WAF tier. For a deeper look at how these tools work, our guide to web application firewalls is a good starting point.
Check Your Backup Situation
Backups aren't a security measure in the traditional sense, but they are your recovery plan when everything else fails. An audit isn't complete without answering these questions:
- Are backups running automatically, and how often?
- Where are they stored — on the same server as your site, or separately?
- When did you last actually test a restore?
Backups stored on the same server as your site are useless if that server gets compromised. You want copies in a separate location. We run daily backups to a separate infrastructure so that even a worst-case scenario leaves you with a clean restore point within 24 hours — but whatever your setup, verify that the backups exist and that you can actually use them. For more on what to look for, see our backup and recovery overview.
Review HTTP Security Headers
Security headers are instructions your server sends to browsers, telling them how to handle your content. They're easy to check and frequently misconfigured.
Visit securityheaders.com and enter your domain. You'll get a letter grade and a breakdown of which headers are present or missing. Key ones to look for:
- Content-Security-Policy (CSP) — limits where scripts and resources can be loaded from, reducing XSS risk.
- X-Frame-Options — prevents your site from being embedded in iframes on other domains (clickjacking protection).
- Strict-Transport-Security (HSTS) — forces browsers to always use HTTPS for your domain.
- X-Content-Type-Options — stops browsers from guessing file types, which can be exploited.
Adding or fixing these headers usually requires a small change to your server configuration or .htaccess file. Your hosting provider should be able to help, or there are plugins for common CMS platforms that handle it automatically.
Audit Your User Permissions
Think about everyone who has access to your site or server: developers, contractors, team members, former employees. Do they still need that access? Do they have more access than their role requires?
The principle of least privilege is simple: give people the minimum access they need to do their job, and nothing more. An editor doesn't need admin rights. A contractor who finished the project six months ago doesn't need any access at all.
Go through your CMS users, hosting panel users, FTP accounts, and SSH keys. Remove anything that's no longer active. This is one of the most overlooked aspects of website security protection, and it costs nothing to fix.
What to Do With Your Findings
After working through this audit, you'll likely have a short list of issues. Prioritize them by risk:
- Critical — fix immediately: missing HTTPS, active malware, no backups, unknown admin accounts.
- High — fix within a week: outdated software, weak passwords, missing 2FA.
- Medium — fix within a month: missing security headers, inactive user accounts, no WAF.
You don't need to solve everything at once. The goal of an audit is to see clearly, then work through the list. Most of these fixes take minutes. The ones that don't are worth knowing about early — before an attacker finds them first.
Security audits like this are worth repeating every few months. Your site changes, your plugins change, your team changes. What was secure six months ago may not be today. We covered exactly this idea in our post on why website security protection is an ongoing practice — it's worth a read once you've finished this first audit.
