# Website security: why take it seriously?

[Nederlands](https://hallobraaf.nl/data/blogposting/website-beveiliging.md) • [English](https://hallobraaf.nl/en/data/blogposting/website-beveiliging.md)

"Who would want to hack my website?" It's the most common question from entrepreneurs who treat security as a nice-to-have. The answer: bots. Automated scripts scanning the internet for known vulnerabilities. They're not looking for specific websites — they're looking for weak spots. And they find them. Every day.

## The risks

### Your website gets hacked

The most obvious one. Your site shows spam, redirects to phishing pages, or gets used to spread malware. Your visitors see it — and so does Google. Result: blacklisting, reputational damage, and a long road back.

### Data breaches

If your website processes customer data — contact forms, orders, accounts — you're responsible for that data. A breach means not just reputational damage, but a possible GDPR fine. And those can run up.

### Ransomware

Your website gets locked. Pay €2,000 in Bitcoin or you lose everything. It sounds like a bad film, but it happens to thousands of websites a year. Without a backup you depend on the goodwill of criminals. Not an ideal position.

### SEO spam

A subtler attack: hackers inject invisible links and pages into your website. You don't notice, but Google does. Your SEO positions plummet, your domain authority drops, and it can take months to recover.

## The most common vulnerabilities

### Outdated software

WordPress not updated? Plugins three versions old? PHP 7.2 while 8.x is available? Outdated software is the number one cause of hacks. Every update contains security patches — not updating is leaving the door open.

### Weak passwords

"Admin123" as the password for your WordPress admin isn't security. Use strong, unique passwords and two-factor authentication (2FA). Always.

### Unsecured forms

Contact forms without validation and protection are an open invitation for SQL injection and cross-site scripting (XSS). Sanitise all input. Always.

### No SSL certificate

HTTPS is no longer a luxury — it's a requirement. Without SSL, all data between your visitor and your server is unencrypted. Chrome warns visitors, Google ranks you lower, and customers don't trust you.

### Poor file permissions

Files and folders with the wrong permissions (777 on a web server, anyone?) are an open door for attackers. Every configuration mistake is an opportunity.

## What can you do?

### Keep everything up to date

WordPress, plugins, theme, PHP — update regularly. Turn on automatic updates for minor releases. Schedule a monthly check for major updates. It's the minimum.

### Make daily backups

When it goes wrong — and it always can — you want to be able to go back to yesterday. Daily backups, in an external location (not on the same server). Test your backups regularly — a backup that doesn't work isn't a backup.

### Use a firewall

A Web Application Firewall (WAF) blocks known attack patterns before they reach your website. Cloudflare offers a free tier. Sucuri and Wordfence are options for WordPress. It's an extra layer of protection.

### Limit access

Who has admin access to your website? Everyone who ever "just had to change something"? Limit it. Remove unused accounts. Don't give everyone full rights.

### Monitor your website

Set alerts for downtime, unauthorised changes and suspicious traffic. You don't want to find out you've been hacked because a customer calls you.

### Choose a host that takes it seriously

Not every hosting provider is equal when it comes to security. Ask about firewall configuration, DDoS protection, isolation between accounts, and how they handle incidents.

## The cost of doing nothing

An average hack costs a small business between €5,000 and €50,000 in recovery, downtime, lost revenue and reputational damage. Prevention costs a fraction of that. It's not a question of "if" you get hacked, but "when" — and how well prepared you are.
