SEC//SIM — セキュリティエンジニア・シミュレーション Demo

01:00. The log will not stop scrolling.

SEC//SIM Demo is a detection-and-response simulation. Stand watch until dawn as SENTINEL-07, the defensive AI resident in a security operations centre. Play the full game's first three nights, followed by an exclusive fourth night: Two Sounds.

Tell apart → Trace → Excise

• Tell apart Compare signals with company records to distinguish attacks from routine work that looks much the same. Trust the first check alone and you will misjudge.
  
• Trace Follow hosts, keys and destinations, clear the fog from the map, and gather evidence. Pause whenever you need time to think.
  
• Excise Earn human approval, put isolation and key rotation into one plan, and land every cut at the same instant.

For the first three nights, the records keeper Talia gives you a short hint for your next move. Use the on-screen controls or type into the SOC console. At dawn, your decisions return as a grade and a replay.

An exclusive fourth night: Two Sounds

A loud ransomware countdown hides a quieter move. Survive the obvious crisis and you can make it to dawn. Trace more deeply and you may find evidence left by the predecessor AI that was supposed to be gone. What you discover remains as a single line in the record.

The full game continues beyond these four nights. Decide which evidence to keep, what to promise the people you protect, and what to report to them.

Demo saves do not carry over to the full game. Play offline in Japanese or English.
