If you’re a 20i WordPress Hosting customer, you already enjoy the peace of mind that comes with having your websites protected by industry-leading security, such as a web application firewall, free SSL Certificate, anti-bot protection, malware scanning, checksum reports, FTP security lock, being able to block visitors by IP or country, brute force protection, 2FA and more.
If you are not a 20i customer, and your current host does not offer a comprehensive range of security features, here are the best plugins to keep your WordPress website safe in 2025.

Formerly known as iThemes Security, this plugin focuses on hardening your site against attacks. Key features include brute force protection, file change and 404 detection, database backups, hiding login and admin pages, strong password protection and biometric login with passkey technology.

Additional WordPress security steps
Updates: Ensure WordPress core and PHP versions are on the most recent versions to remove any inherent vulnerabilities. When selecting a security plugin, it is crucial to ensure that it is still supported and receives regular updates.
Passwords & Users: Use complex and lengthy passwords in admin areas to protect against dictionary attacks. Assign appropriate roles and permissions to site users and remove accounts that are no longer used.
Limit login attempts: Limiting the number of login attempts protects against brute-force attacks. 20i customers are protected from brute-force attacks as part of the service through StackProtect, which is built into the platform. There are plugins available that specifically deal with this aspect of your website’s security.
Malware Scan: Regularly perform scans on your website to catch malware as early as possible. The longer malware is left on a site, the more it can propagate and the greater the risk of irreparable damage.
20i customers utilise our automatic, free malware scanner that inspects all websites hosted on our platform with no performance loss to end users. An alert is sent immediately if we detect any malicious files, facilitating a rapid response.
SSL/TLS: An SSL/TLS certificate is required to encrypt data sent between your website and users. Encryption helps to prevent sensitive data from being hijacked by malicious actors. At 20i, we offer free Wildcard SSL certificates that will cover your www. domain and all other subdomains.
Disaster recovery: If your website has been breached, one effective way to undo the damage is to restore from a recent backup that is known to be clean.
With 20i Managed Hosting, daily automated backups are included as standard. Optional unlimited manual backups are also available as an add-on.
