CS2 SecureWatch
Managed Security Monitoring & Log Intelligence
Your security logs already record what matters. What is usually missing is someone reading them every day. SecureWatch connects to your existing log platform, enriches every alert with geolocation and threat intelligence, and uses AI triage to turn thousands of daily events into a short, bilingual report your team will actually read.

Your logs stay on your systems
SecureWatch reads from your existing log platform over a read-only connection. Nothing runs on your servers except detection rules you can inspect.
AI triage, not alert noise
Every alert is enriched with geolocation, network ownership and threat intelligence, then triaged by AI. You receive the few findings that matter, explained in plain language.
Real-time alerts in Teams and email
High-severity events reach your team within minutes, in Japanese and English, with the context needed to act.
Coverage you can see
Every report opens with a coverage check: which log sources reported and which devices went quiet. Silence is never mistaken for safety.
