You don't need to become a security expert to protect your business website. But you do need to understand the basics. Here's what every business owner should know about keeping their website - and their customers - safe.
Why Website Security Matters for Your Business
It's Not Just About Getting Hacked
When most people think about website security, they imagine sophisticated hackers specifically targeting their business. The reality is different - and in some ways, more concerning.
Most attacks are automated. Bots constantly scan the internet looking for vulnerable websites. They don't care who you are; they're looking for easy targets. If your site has known vulnerabilities, it will be found.
The consequences extend beyond your website:
- Customer data theft - Contact details, payment information, personal data
- Reputation damage - Google may flag your site as dangerous
- SEO impact - Hacked sites can be penalised or removed from search
- Legal liability - GDPR requires you to protect customer data
- Business disruption - Downtime while you recover
- Financial loss - Cleanup costs, lost sales, potential fines
The Common Threats
1. Brute Force Attacks
Bots try thousands of username/password combinations trying to guess their way in. "admin/password123" is tried within seconds.
Protection: Strong passwords, limit login attempts, two-factor authentication.
2. Software Vulnerabilities
Outdated WordPress versions, plugins, or themes often have known security holes. Attackers know these vulnerabilities and actively exploit them.
Protection: Keep everything updated. Delete plugins and themes you're not using.
3. SQL Injection
Attackers insert malicious code through forms or URLs to access your database. If successful, they can steal, modify, or delete data.
Protection: Use reputable software that sanitises inputs. Keep everything updated.
4. Cross-Site Scripting (XSS)
Malicious scripts are injected into your pages that then run in visitors' browsers, potentially stealing their data.
Protection: Use reputable themes and plugins. Keep everything updated.
5. Phishing and Social Engineering
Someone pretends to be your host, registrar, or a customer to trick you into revealing passwords or access.
Protection: Verify requests independently. Never share passwords via email.
The Essential Security Measures
1. SSL Certificate (HTTPS)
This encrypts data between your website and visitors. Without it:
- Browsers show "Not Secure" warnings
- Customers won't trust entering payment details
- Google treats it as a minor ranking factor
- Form data can be intercepted
Action: Ensure your site uses HTTPS. Most hosts now provide free SSL certificates via Let's Encrypt.
2. Strong Passwords
The most common way sites get compromised is through weak passwords. Yet people still use "password123" and "admin."
Good passwords are:
- At least 12 characters long
- A mix of letters, numbers, and symbols
- Not based on dictionary words or personal information
- Unique to each account
Action: Use a password manager (Bitwarden, 1Password, LastPass) to generate and store strong, unique passwords.
3. Two-Factor Authentication (2FA)
Even if someone gets your password, they can't log in without the second factor - typically a code from your phone.
Action: Enable 2FA on your website admin, hosting account, domain registrar, and email.
4. Regular Updates
Keeping software updated is one of the most effective security measures. Updates often fix known vulnerabilities.
Action: Update WordPress core, themes, and plugins regularly. Enable automatic updates where sensible.
5. Regular Backups
When everything else fails, backups let you restore your site. Without them, a successful attack could mean rebuilding from scratch.
Good backup practice:
- Daily automated backups (at minimum, weekly)
- Store backups off-site (not just on the same server)
- Test that you can actually restore from backups
- Keep multiple backup versions
Action: Confirm your host provides backups. Consider an additional backup plugin or service.
6. Security Plugins/Features
On WordPress, security plugins add layers of protection: firewalls, malware scanning, login protection, and monitoring.
Popular options:
- Wordfence (free and premium)
- Sucuri Security
- Solid Security (formerly iThemes)
Action: Install and configure a reputable security plugin.
Questions to Ask Your Web Developer
If someone else manages your website, ask them:
-
"Is my site backed up? How often? Where are backups stored?" Good answer: Daily backups stored off-site, with ability to restore quickly.
-
"How do you handle security updates?" Good answer: Regular updates on a schedule, with testing to ensure nothing breaks.
-
"What security measures are in place?" Good answer: SSL, firewall, login protection, malware scanning, strong passwords.
-
"What happens if my site gets hacked?" Good answer: We have a recovery process, recent backups, and can restore quickly.
-
"Who has admin access to my site?" Good answer: Only you and [specific people], each with their own login.
Security Hygiene Habits
Monthly Tasks
- Check for and install updates
- Review user accounts - remove any that shouldn't be there
- Verify backups are running
- Scan for malware
Quarterly Tasks
- Change passwords for critical accounts
- Review who has access to what
- Check for unused plugins and themes - delete them
- Review security plugin logs
Yearly Tasks
- Full security audit
- Review hosting and security services
- Update recovery procedures
- Test backup restoration
What to Do If You've Been Hacked
Don't panic, but act quickly:
- Don't make changes yet - Preserve evidence of what happened
- Contact your host - They may have dealt with this before
- Restore from backup - The cleanest solution if backups are recent
- Change all passwords - Every account associated with the site
- Update everything - Close the vulnerability that was exploited
- Scan for malware - Ensure no malicious code remains
- Monitor closely - Watch for signs of reinfection
- Report to Google - If flagged as dangerous, request a review once clean
If you're not comfortable doing this yourself, professional cleanup services typically cost £200-500.
Platform Comparison
Wix/Squarespace
Security is largely handled for you. Updates are automatic. Your main responsibilities are strong passwords and being careful with third-party apps.
WordPress (Self-Hosted)
More control but more responsibility. You need to manage updates, backups, and security plugins. Choose good hosting.
Custom-Built Sites
Security depends entirely on how it was built and is maintained. Ask your developer about their security practices.
The Bottom Line
Website security isn't about preventing every possible attack - it's about not being an easy target. Most attackers move on when they hit resistance.
Focus on the basics:
- SSL certificate (HTTPS)
- Strong, unique passwords
- Two-factor authentication
- Regular updates
- Reliable backups
- A security plugin or service
Do these things consistently, and you'll be better protected than the majority of small business websites. That matters - because attackers go for the easy targets first.
