CentOS - Oct 2022 - security monitoring tools to scan and monitor CentOS Linux release 7.9.2009 (Core)

Hi,

I am running GitLab SCM on CentOS Linux release 7.9.2009 (Core) and this
service is monitored by Nagios for host and service checks. Are there any
security monitoring tools to scan and monitor continuously the CentOS Linux
release 7.9.2009 (Core) system and trigger alerts via email or slack if
the tool reports any vulnerabilities?

Thanks in advance.

Best Regards,
