Your website can have the best design and the best sales, but if it gets hacked on a Friday night, you don't have a business on Monday. Web security isn't an extra: it's the infrastructure that protects your billing, your data and your customers' trust.

The most common attacks on business websites

• ●SQL injection: attackers manipulate forms to access your database (customers, passwords, payments).
• ●Cross-Site Scripting (XSS): they inject malicious code into your website that steals visitor data.
• ●CMS and plugin attacks: 90% of WordPress hacks happen through outdated plugins or themes.
• ●Brute force: automated attempts to guess passwords on your admin panel.
• ●Ransomware and defacement: hijacking your website or replacing its content to damage your brand.

The first line of defense: SSL and HTTPS

SSL (Secure Sockets Layer) is the certificate that encrypts communication between the visitor and your server. With it, your website is served over HTTPS —the padlock in the browser— and data travels protected.

• ●Visible trust: without HTTPS, browsers mark your site as "Not secure" and Google penalizes it.
• ●Encrypted data: forms, payments and logins are protected from interception.
• ●SEO requirement: HTTPS is a ranking signal and a condition for many integrations.

The mandatory defenses beyond SSL

• ●Ongoing updates: systems, libraries and dependencies up to date. Most attacks exploit already-known vulnerabilities.
• ●Automatic backups: restore in minutes after any incident. Without backups, an attack can be irreversible.
• ●Access control: two-factor authentication, strong passwords and minimum permissions for each user.
• ●Monitoring and alerts: detect unusual access, outages or suspicious changes before they become a problem.
• ●Avoiding vulnerable platforms: the more plugins and exposed panels, the larger the attack surface. Custom code eliminates that risk at the root.

Signs your website has already been compromised

• ●Sudden slowdown (your server is processing foreign tasks).
• ●Content or links appearing that you didn't publish.
• ●Browser or Google Search Console alerts about malware.
• ●Forms receiving unusual spam.

How to protect your business in 5 steps

1. ●Verify HTTPS and SSL across your entire website (not just one page).
2. ●Enable daily automatic backups with at least 30 days of retention.
3. ●Update everything: CMS, plugins, libraries and dependencies.
4. ●Strengthen access: 2FA for admins and unique passwords.
5. ●Monitor actively with security tools and alerts.
