Why Is Web Security More Important Than Ever?
Cyber attacks increase every year in both number and sophistication. In 2025, 43% of small and medium-sized businesses suffered at least one cyber attack. And the vast majority of those businesses had not taken adequate security measures.
Your website is your business's digital storefront. Security vulnerabilities can lead not only to data loss but also to a loss of customer trust and serious financial damage. Here are the threats you need to protect your website against in 2026 and the measures to take.
The Most Common Web Security Threats
The main types of attack threatening websites in 2026 are:
- SQL Injection: Gaining unauthorised access to data by injecting malicious code into database queries
- XSS (Cross-Site Scripting): Stealing user information by planting malicious JavaScript on a web page
- CSRF (Cross-Site Request Forgery): Forcing a user to perform unwanted actions without their knowledge
- DDoS Attacks: Crashing a web server by flooding it with requests
- Ransomware: Encrypting data and demanding a ransom
- AI-Powered Phishing: Highly convincing fake emails and web pages created with artificial intelligence
SSL/TLS Certificate: The Basic Security Layer
Using HTTPS is no longer an option but a necessity. Browsers mark sites without an SSL certificate as "Not Secure". This makes your visitors distrust your site and leave immediately.
An SSL certificate encrypts all data traffic between your site and the user. Credit card details, passwords and personal data are transmitted securely. You can get a free SSL certificate with Let's Encrypt.
Strong Password and Authentication Policy
Weak passwords are the most common cause of security breaches. The password policy you should apply in your business:
- Passwords of at least 12 characters should be mandatory
- A combination of uppercase letters, lowercase letters, digits and special characters should be required
- Two-factor authentication (2FA) must be enabled
- Passwords should be changed at regular intervals (every 90 days)
- The same password should not be used across different systems
Don't Delay Software Updates
Postponing updates to your CMS (WordPress, Joomla, etc.), plugins and themes is a major risk. Once known vulnerabilities are published, attackers exploit them quickly.
Update strategy:
- Apply security updates within 24 hours
- Test feature updates in a staging environment before going live
- Completely remove unused plugins and themes
- Enable automatic updates (for security patches)
Using a Firewall (WAF)
A Web Application Firewall (WAF) analyses requests coming to your site and blocks malicious ones. It automatically detects and blocks attacks such as SQL Injection, XSS and DDoS. Services like Cloudflare and Sucuri offer both CDN and WAF.
A Comprehensive Backup Strategy
Even if you take the best security measures, 100% security is not possible. That's why a solid backup strategy is a lifesaver:
- Make automatic daily backups (database + files)
- Store backups in a different physical location (a different data centre or the cloud)
- Keep at least 30 days of backup history
- Test restoring from backup regularly (once a month)
- Encrypt the backup files as well
Security Auditing and Monitoring
A proactive security approach aims to detect attacks before they happen. Run regular security scans, monitor access logs and set up an automatic alert system for abnormal activity.
