Taking Precautions with "en caso de que"
When taking a precaution against a hypothetical situation, use the phrase en caso de que (in case / in the event that).
Because the situation hasn't actually happened yet, en caso de que is always followed by the subjunctive mood.
| We have the backup in case there is a cyberattack. | Tenemos la copia de seguridad en caso de que haya un ciberataque. |
| We encrypt the data in case a cyberattack happens. | Encriptamos los datos en caso de que ocurra un ciberataque. |
Notice how the verbs after the phrase (haya, ocurra) are in the present subjunctive. The first half of the sentence uses the indicative mood to state the concrete action you are taking.
| The server blocks the access in case an intruder enters. | El servidor bloquea el acceso en caso de que entre un intruso. |
| The firewall blocks the software in case it is malicious. | El cortafuegos bloquea el software en caso de que sea malicioso. |
| The engineer (m) saves the files in case the hacker deletes them. | El ingeniero guarda los archivos en caso de que el pirata informático los borre. |
| I have a backup in case you lose access. | Tengo una copia de seguridad en caso de que pierdas el acceso. |
