Sample Hardening Report
Every engagement includes detailed documentation of findings and changes.
Common Questions
Which operating systems do you support?
Linux distributions (Ubuntu, Debian, CentOS, RHEL, Alpine) and Windows Server. Cloud VMs and on-premises systems.
Will hardening disrupt my applications?
Changes are planned carefully. I test in stages and can work during maintenance windows to minimize risk.
Do you implement the changes or just recommend them?
Both options available. I can implement directly with your approval, or provide detailed runbooks for your team.
How long does a hardening engagement take?
Depends on scope and complexity. Typically 1-2 weeks for assessment and implementation. Fixed quote after discovery call.
