Over 30,000 websites are hacked every day. The attacks are almost entirely automated — bots scan millions of sites simultaneously, looking for known vulnerabilities that can be exploited in seconds.
The good news: most website hacks are preventable. This guide covers every layer of protection, from free steps you can implement today to professional services that handle security on your behalf.
How Websites Get Hacked: The Most Common Attack Vectors
Understanding how attacks work makes the protection measures easier to understand:
1. Vulnerable Plugins and Themes (56% of hacks)
This is the #1 cause of website infections. Every popular CMS plugin is a target — when a vulnerability is discovered in a widely-used plugin, automated bots scan millions of sites within hours to find unpatched installations.
Protection: Keep everything updated. Enable automatic security updates. Use a WAF with virtual patching (Sucuri patches new vulnerabilities within hours of disclosure).
2. Brute Force Attacks (16% of hacks)
Bots attempt thousands of username/password combinations per minute against your login page. Default admin usernames, common passwords, and sites without login attempt limits are easy targets.
Protection: Two-factor authentication (2FA) makes brute force attacks effectively impossible. Rate limiting and IP blocking stop bots before they reach 2FA.
3. SQL Injection and XSS (12% of hacks)
Attackers inject malicious code through forms, URL parameters, and comment fields. SQL injection targets your database; XSS (Cross-Site Scripting) targets your visitors.
Protection: A WAF blocks these attacks at the network level. Input validation at the application level provides a secondary defense.
4. Stolen Credentials (10% of hacks)
FTP passwords, hosting panel credentials, and database passwords obtained through phishing or credential leaks.
Protection: Unique passwords for everything, 2FA on hosting panel and FTP, regular password audits.
5. Supply Chain / Malicious Plugins (6% of hacks)
Downloading themes or plugins from unofficial sources (nulled plugins, pirated themes) is one of the fastest ways to infect your own site. These files frequently contain backdoors.
Protection: Only install plugins and themes from official repositories or reputable vendors. Never install nulled software.
The Complete Website Protection Checklist
Layer 1: Web Application Firewall (WAF) — Your First Line of Defence
A WAF filters all incoming traffic before it reaches your website. It blocks SQL injection, XSS, DDoS attacks, bad bots, and known malicious IP addresses in real time.
Free option: Cloudflare Free — excellent CDN and basic DDoS protection, no WAF rules on the free tier
Best value: Sucuri Basic ($199.99/year) — DNS-level WAF with security-focused ruleset, virtual patching for CMS vulnerabilities, global CDN included
WordPress-specific: Wordfence Free or Premium ($119/year) — plugin-level WAF with malware scanner
The key advantage of Sucuri's DNS-level WAF: attacks are blocked before they reach your server. Even if WordPress itself is compromised, the WAF continues protecting you.
Layer 2: Malware Scanning — Detect Infections Early
Malware is often present on sites for weeks before being detected. Early detection limits damage.
Free scanner: Run Sucuri SiteCheck weekly — free remote scan that checks for malware, blacklisting, and outdated software
Continuous monitoring: Sucuri's paid platform ($199.99+/year) runs continuous server-side scans, not just remote surface scans — detecting hidden backdoors and obfuscated malware that remote scanners miss
WordPress scanner: Wordfence (free) provides on-demand scans. Premium provides real-time scanning with updated signatures.
Layer 3: Keep Everything Updated
Outdated software is the primary attack vector. A site running WordPress 6.0 with a vulnerable plugin is attacked within hours of the vulnerability being made public.
Action steps:
- Enable automatic WordPress core updates (security releases only is fine)
- Update plugins and themes weekly — or enable automatic updates for trusted plugins
- Remove inactive plugins and themes (inactive doesn't mean safe — they still have exploitable code)
- Check your PHP version — sites running PHP 7.x are running unsupported software with known vulnerabilities
Layer 4: Authentication Hardening
Strong authentication stops credential-based attacks entirely.
Enable two-factor authentication: Use the WP 2FA plugin (free) for WordPress admin, or enable 2FA in your hosting control panel. With 2FA active, stolen passwords alone cannot compromise your account.
Change your admin username: Never use "admin" as your WordPress username — it's the first guess of every brute force bot.
Use unique, strong passwords: Use a password manager (Bitwarden is free) to generate and store 20+ character passwords for every account. Never reuse passwords across sites.
Limit login attempts: The Limit Login Attempts Reloaded plugin (free) blocks IP addresses after a configurable number of failed logins.
Layer 5: Backups — Your Recovery Safety Net
Backups don't prevent attacks, but they let you recover quickly without paying for professional cleanup.
Backup requirements:
- Daily automated backups (minimum)
- Offsite storage — backups stored on the same server are useless if the server is compromised
- Tested backups — verify you can actually restore from your backup before you need it in an emergency
- Backup retention — keep at least 30 days of backups (malware sometimes sits dormant for weeks before activating)
Free option: UpdraftPlus free tier with Google Drive or Dropbox storage
Paid option: JetPack Backup or your host's backup service (Cloudways, SiteGround, WP Engine all include daily backups)
Layer 6: SSL/HTTPS — Encrypt All Traffic
Every website should be running HTTPS. SSL encrypts data between visitors and your server, preventing man-in-the-middle attacks.
Free SSL: All reputable hosts include Let's Encrypt SSL certificates. Enable HTTPS and force all traffic to HTTPS via your hosting panel or a plugin like Really Simple SSL.
Monitor expiry: SSL certificates expire (typically every 90 days for Let's Encrypt). Sucuri includes SSL monitoring and alerts as part of their paid platform.
Layer 7: Server-Level Hardening
If you have server access (VPS, cloud hosting), additional hardening reduces your attack surface:
- Disable XML-RPC if unused (common brute force target)
- Protect wp-config.php and .htaccess from direct access
- Disable directory listing
- Limit file permissions (folders: 755, files: 644)
- Use a dedicated database user with minimal permissions
Most WordPress hosts (Cloudways, SiteGround, Kinsta) apply server-level hardening automatically.
What to Do If Your Website Is Already Hacked
Step 1: Don't panic — take notes Document what you see: warning messages, redirects, when you first noticed the issue. This information helps with cleanup.
Step 2: Inform your hosting provider Your host may have detected the malware already and can help identify infected files. Some hosts (Cloudways, SiteGround) include basic malware cleanup.
Step 3: Take your site offline temporarily Enable maintenance mode or temporarily password-protect your site while cleaning. This protects your visitors from drive-by download attempts.
Step 4: Clean the malware
Option A — Professional cleanup (recommended): Sucuri's malware removal service handles end-to-end cleanup — finding and removing all infected files, closing the entry point, and submitting Google blacklist removal. Response time: 4–30 hours depending on plan.
Option B — Restore from clean backup: If you have backups from before the infection, restore to the last clean version. Then update everything and change all passwords before bringing the site back online.
Option C — Manual cleanup: Use a scanner to identify infected files, manually remove or replace them, and audit all admin accounts. This requires technical knowledge and is time-consuming. Risk of missing hidden backdoors is high.
Step 5: Harden and prevent re-infection After cleanup: change all passwords, review admin user list, update all software, enable 2FA, and implement a WAF to prevent future attacks.
How Much Does Website Security Cost?
| Approach | Annual Cost | Protection Level | |----------|-------------|-----------------| | Free stack (Wordfence Free + Cloudflare Free + WP 2FA) | $0 | Good baseline | | Wordfence Premium | $119/year | Strong WordPress-level WAF | | Sucuri Basic | $199.99/year | Complete: WAF + CDN + unlimited malware removal | | Sucuri Pro | $299.99/year | Faster malware SLA (12 hours) | | Professional malware removal (one-time, if hacked) | $300–$500 per incident | Reactive only |
The math: One malware removal incident from a freelance developer costs $300–$500. Sucuri's annual plan at $199.99 covers unlimited removals, plus WAF and CDN. The economics strongly favour proactive security.
