Managed firewall vs doing it yourself

Sized, configured and managed as one service — not boxes you wire together yourself.

You can buy a firewall and run it yourself, or have it rented and run for you. A firewall is only as strong as its configuration — and configurations drift as rules pile up and exceptions are forgotten. Here is how the two approaches compare.

The hardware

Managed: the Firebox is rented for the term with a one-time fee. Do it yourself: you buy it up front and refresh it on your own budget.

Setup and licensing

Managed: configured for your site before it ships, with the security-suite licensing included in your plan. Do it yourself: your team configures it, and you track and renew the licenses.

Audits and fixes

Managed: NinjaToolKit audits the firewall in about a minute on a regular schedule; every fix gets a backup, an undo plan and an engineer's approval, and the next audit confirms the fix held. Do it yourself: a manual audit of the same depth takes a senior engineer 60 to 80 hours as a one-off snapshot, and fixes are made by whoever has time, often without a rollback plan.

The bottom line

Buying a box gives you hardware and a to-do list. A managed plan gives you a firewall that stays configured, licensed, current and audited — with one team responsible for the result.
