Why This Matters

A Firewall Is Not a One-Time Purchase

Most business firewalls are configured once, at install, and never actively managed again. These are the problems that creates.

🛡️

Configured Once, Never Touched Again

The firewall was set up at install and hasn't been reviewed, patched, or adjusted since - rules nobody remembers the reason for.

We take over ongoing configuration and management, so your firewall stays actively maintained, not just installed.

📋

Rule Sprawl Nobody Understands

Years of ad-hoc access requests have left a rule set that's grown without anyone reviewing whether old rules are still needed.

We clean up and maintain rule hygiene on a regular schedule, removing what's no longer needed and documenting what remains.

⚙️

Firmware and Patches Falling Behind

Firmware updates get postponed indefinitely because nobody owns the job of testing and applying them.

Patches and firmware updates are applied on a scheduled cadence, timed to minimise disruption to your business.

🔐

No Change Control When Access Is Needed

A new vendor or staff member needs access and someone opens a rule under time pressure, with no record of why.

Every change request goes through a documented process, so there's always a clear record of what changed and why.

📊

Nobody Watching for Firewall-Related Outages

A misconfigured rule or failed update takes down connectivity, and nobody notices until staff can't work.

We monitor firewall health and connectivity as part of the managed service, catching issues before they become outages.

📄

No Documentation of What's Configured

Nobody has a current record of the rule set, access policies, or why the firewall is configured the way it is.

Every engagement starts with an audit and produces documentation of the current configuration - not a generic checklist.

Common Questions

Managed Firewall FAQ

What business owners and IT managers ask about ongoing firewall management.

What's the difference between managed firewall and managed security services?

Managed Firewall & Perimeter, as offered by ManagedNetwork.Asia, focuses on the firewall as network infrastructure - deployment, uptime, rule hygiene, patching and change management. Deeper security capability like intrusion prevention, DNS filtering and geo-blocking is covered by our sister site, ManagedSecurity.Asia.

Do you replace our existing firewall hardware?

Not necessarily. We assess your current firewall during the audit and work with what's already in place where practical, recommending a replacement only when the existing hardware genuinely can't support what your business needs.

How often are firewall rules reviewed?

Rules are reviewed on a regular scheduled cadence as part of the ongoing management service, plus whenever a change request comes in - so the rule set reflects how your business actually works today, not what it needed years ago.

Do you handle firmware and patch updates?

Yes. Firmware and patch updates are applied on an ongoing basis as part of the managed service, with updates scheduled to minimise disruption to your business.

How do we get started?

Schedule a free consultation. We'll review your current firewall setup and recommend the right level of ongoing management for your business.
