Stop security incidents before they cost you thousands.
Professional file and code monitoring with 2-second change detection, forensic reports, and instant alerts.
The Problem: Unauthorized code changes can cost your company thousands in minutes. Traditional monitoring tools take hours to detect and investigate changes. By then, the damage is done.
The Solution: CoNum detects critical file changes in 2 seconds and gives you forensic-grade change reports instantly.
- 🛡️ Security Operations Centers (SOCs)
- 👨💻 DevOps/SRE teams
- 📋 Compliance officers (SOC 2, ISO 27001, PCI-DSS)
- 🔐 Anyone monitoring critical code assets
Monitor ~/.ssh/authorized_keys and get alerted within 2 seconds if someone adds an unauthorized key.
Know immediately when .env files, nginx.conf, database configs, or deployment scripts are modified.
Generate forensic reports for SOC 2, ISO 27001, or PCI-DSS audits showing exactly who changed what and when.
When a breach happens, CoNum's change history shows exactly which files were compromised and what was changed.
Ensure deployment scripts and infrastructure-as-code haven't been tampered with before running automated deployments.
