SSL certificates are digital certificates that encrypt the communication between your website and your visitors' browsers. They ensure that any data that is exchanged, such as personal information, credit card details, or login credentials, is protected from eavesdropping, tampering, or spoofing. SSL certificates also help you build trust and credibility with your visitors, as they can see the padlock icon and the HTTPS protocol in the address bar. To get an SSL certificate, you need to purchase one from a trusted authority and install it on your web server.

Cloudflare provides DDoS protection, a Web Application Firewall (WAF), and SSL/TLS encryption, while Google Authenticator offers two-factor authentication (2FA) via time-based one-time passwords (TOTP). These tools bolster website security by mitigating attacks, filtering malicious traffic, encrypting data in transit, and adding an extra layer of authentication beyond passwords, significantly enhancing the protection and integrity of user information.
A web application firewall (WAF) is a software or hardware device that monitors and filters the incoming and outgoing traffic to your website. It can detect and block malicious requests, such as SQL injection, cross-site scripting, or brute force attacks, that try to exploit vulnerabilities in your web application. A WAF can also prevent denial-of-service (DoS) attacks, which aim to overwhelm your website with excessive requests and make it unavailable. A WAF can be deployed on your web server, on a cloud service, or on a separate appliance.
Malware scanning and removal is a process of detecting and eliminating any malicious code that may have infected your website. Malware can cause various problems, such as redirecting your visitors to other websites, displaying unwanted ads, stealing your data, or harming your reputation. Malware scanning and removal can be done manually, by checking your files and database for any suspicious changes, or automatically, by using a tool that scans your website regularly and alerts you of any issues. Some tools can also remove the malware for you or help you restore a clean backup of your website.
Content security policy (CSP) is a web standard that allows you to control what resources can be loaded and executed on your website. It can help you prevent cross-site scripting (XSS) attacks, which involve injecting malicious code into your website that can harm your visitors or steal their data. CSP works by sending a header from your web server to your visitors' browsers, which specifies what sources of content are allowed and what are not. For example, you can whitelist your own domain and block any external scripts, images, or stylesheets that may be malicious.
Two-factor authentication (2FA) is a method of verifying your identity when you log in to your website or web application. It adds an extra layer of security to your password, by requiring you to enter a code that is generated by another device or app, such as your phone or email. This way, even if someone steals or guesses your password, they cannot access your website without the code. 2FA can be implemented using various tools and services, such as Google Authenticator, Authy, or SMS. You can enable 2FA for yourself, your staff, or your users.
Security headers are HTTP headers that instruct your visitors' browsers how to behave when they interact with your website. They can help you enhance your website security by enforcing various policies and rules, such as preventing clickjacking, disabling browser caching, or restricting iframe embedding. Security headers can be configured on your web server, by editing the .htaccess file or the server configuration file. Some examples of security headers are X-Frame-Options, X-XSS-Protection, X-Content-Type-Options, Strict-Transport-Security, and Content-Security-Policy.
