CrowdSec is a security automation engine, using both local IP behavior detection & our community-driven IP reputation database.
SpyLog Alternatives
SpyLog is described as 'Monitor logs from several sources and execute actions based on some rules. Can be used to protect against brute-force attacks' and is a Remote Desktop tool in the network & admin category. There are more than 10 alternatives to SpyLog for Windows, Linux, Web-based, Self-Hosted and Mac. The best SpyLog alternative is CrowdSec. It's not free, so if you're looking for a free alternative, you could try CrowdSec or Fail2ban. Other great apps like SpyLog are IPBanPro, reaction, Denyhosts and RdpGuard.

SSHGuard monitors services through their logging activity. It reacts to messages about dangerous activity by blocking the source address with the local firewall. SSHGuard employs a clever parser that can transparently recognize several logging formats at once (syslog, syslog-ng...
IPBan is a FREE and open source application that allows auto banning ip addresses from failed login attempts. Many sources are watched such as SSH, SMTP, SQL-Server, MySQL, RDP and dropped packets.
