FAQ

SSH Hardening FAQ

Common questions before starting fixed-scope infrastructure, automation or support work.

Can you review the current reliability or security setup?

Yes. We can review backups, restore readiness, monitoring, alerts, access controls, SSH, exposed services and practical hardening gaps.

What information should we send?

Useful details include the affected system or service name, what changed before the issue appeared, relevant logs, errors or screenshots with secrets removed, with secrets removed.

Do you test that backups actually work?

Yes, where part of the agreed scope. Restore testing is often the most important part of a backup or disaster recovery review.

Can you set up monitoring and alerts?

Yes. We can help with uptime checks, service checks, resource alerts, backup status alerts and practical operational monitoring.

How much does this work usually cost?

SSH and access-control support may start from $299 for small tasks, with hardening work quoted separately.

After the fix

Reduce the chance of the same issue returning.

After a fixed-scope issue is resolved, we can also help with monitoring, backups, restore testing, security hardening or ongoing infrastructure support where it makes sense.
