Fail2ban- Gemini
Fail2Ban is a log-driven intrusion prevention tool that detects repeated authentication failures (and other suspicious patterns) and applies temporary IP bans using the host firewall. On WordPress VPS servers, it is most commonly used to reduce brute-force pressure against SSH and other exposed services by automatically blocking abusive sources after a configurable number of failures.
Fail2Ban
Fail2Ban is a log-based intrusion prevention tool that monitors service logs for suspicious activity (such as repeated authentication failures) and applies temporary bans using the host firewall. It is commonly used to reduce brute-force attempts against SSH and other internet-exposed services on Linux servers.
SSHGuard
SSHGuard is a lightweight intrusion prevention tool that blocks IP addresses exhibiting suspicious behavior, typically repeated authentication failures against SSH. Like Fail2Ban, it reacts to log activity and applies temporary firewall blocks. SSHGuard is often chosen when you want a simpler, lower-maintenance solution with fewer moving parts, especially on servers where you primarily need SSH brute-force suppression.
