FAQ
Do you need full admin access to my firewall?
Yes, I need read-write administrative access to make any changes. A dedicated temporary admin account works perfectly — I'll remind you to delete or disable it once we're done. I do not store credentials after the engagement.
How do we connect for the remote session?
I work via screen share — AnyDesk, TeamViewer, Zoom, or your preferred tool. If your firewall is behind a jump host or accessible only through a site VPN, just let me know in advance and we'll plan accordingly. No direct exposure of your management interface to the internet is required.
My firewall is already set up but something isn't working. Which package should I pick?
Please message me before placing an order. I will provide you with a custom quote tailored to your specific requirements.
Can you work on a firewall model not listed in your gig?
Message me first. I focus on Sophos XGS/XG, FortiGate, and Palo Alto. There's a good chance I can still help. I'll be upfront if it's outside my wheelhouse.
Will you document what you changed?
Standard and Premium packages include a written handover note covering every change made, the reason for it, and any recommendations for follow-up. Basic includes a brief verbal summary during the session. If you need formal documentation on Basic, it's available as a paid add-on.
What if the issue isn't resolved within the agreed scope?
I'll always tell you upfront if I discover the problem is larger than the package covers — before doing extra work. We can either upgrade the order or I'll explain exactly what you'd need to do next so you're never left stuck. I don't run up scope silently.
Is my network information kept confidential?
Yes. I treat all client environments, IP schemes, policy details, and credentials as strictly confidential. If your organization requires it, I'm happy to sign an NDA before we begin — just mention it when you message me.
Do you offer ongoing support after the gig is delivered?
The gig covers a one-time engagement. That said, if you'd like a retainer arrangement for ongoing firewall support — monthly check-ins, policy updates, or priority response — message me and we can discuss a custom monthly package.
