Alertica is a cloud-based server monitoring platform that delivers real-time alerts when files on monitored servers are accessed, modified, uploaded, or deleted, helping teams detect suspicious behavior before it escalates into security incidents. It enables organizations to define custom monitoring rules for specific files, folders, or entire servers and route alerts to the appropriate teams through channels such as email, Slack, or SMS. It supports a wide range of environments across cloud, on-premises, or hybrid infrastructure, and is designed to work without installing agents or consuming server resources. It focuses on early threat detection and operational visibility by flagging events such as executable uploads, configuration changes, mass deletions, log overflows, or unusual file size violations. Alertica monitors only file metadata such as names, sizes, and timestamps rather than file contents, preserving data privacy.
