Firewall Security

Assessment, hardening, and ongoing management of your firewall controls — documented, reviewed, and maintained, not set once and forgotten.

The problem

Firewalls configured once tend to stay that way — long after the business has changed.

Firewall rules typically get set up during initial network deployment and rarely get revisited. Over time, rules accumulate, ownership becomes unclear, and no one is confident about what's actually allowed through the perimeter anymore.

  • The person who originally configured the firewall has often moved on, taking the institutional knowledge of why each rule exists with them.
  • Rules accumulate over years with no process for retiring the ones that are no longer needed.
  • An overly permissive or outdated ruleset is a direct, avoidable path for unauthorized access.
  • Partners, customers, and insurers increasingly ask about network security practices during procurement and renewal — an undocumented firewall is a difficult thing to answer for.
  • Changes made under time pressure, without review, are a common source of new, unintended exposure.

Business outcomes

What changes for your business.

A documented, understood configuration

Know exactly what your firewall allows and why, instead of inheriting an undocumented legacy setup.

Reduced unnecessary exposure

Stale and overly permissive rules are identified and retired before they become a liability.

A safe, reviewed change process

Changes are made deliberately, with review, rather than under time pressure with no oversight.

Continuity independent of any one person

Institutional knowledge of your network perimeter no longer depends on a single employee.

A credible answer when asked

Respond to partner, customer, and insurer questions about network security with confidence.

Our approach

What ongoing firewall management actually requires.

Real perimeter security is a maintained practice, not a one-time configuration.

Configuration Assessment

A clear-eyed review of your current firewall configuration and what it's actually allowing through.

Rule Review & Hardening

Identification and retirement of stale or overly permissive rules, tightening exposure without disrupting legitimate traffic.

Managed Administration

Ongoing, careful management of your firewall so changes are made safely and deliberately.

Recurring Policy Review

Regular reassessment as your network and business needs change, keeping the configuration current.

What's included

Documented, managed, and reviewed — on a recurring basis.

Everything below is delivered as an ongoing engagement, not a one-time project.

Firewall Configuration Assessment

A full review of your existing rules, documenting what's in place and why.

Rule Cleanup & Documentation

Retirement of unnecessary rules and clear documentation of what remains.

Managed Firewall Administration

Day-to-day management of your firewall, with changes made carefully and deliberately.

Recurring Policy Review

A regular cadence of reassessment as your environment changes.

How it works

A managed practice, not a one-time project.

Firewall Security follows a defined, recurring cadence rather than a single configuration pass.

Who this is for

Built for businesses operating firewalls without dedicated network security staff.

Firewall Security fits organizations whose need is specifically firewall management, without the broader scope of Managed Security Foundation.

  • Operates one or more firewalls — network perimeter, branch offices, or cloud security groups.
  • The current configuration predates the people now responsible for the business.
  • No dedicated network or security administrator on staff.
  • Needs changes made safely, with a clear process, rather than ad hoc.
  • A need that's specifically firewall management, not the full combined scope of Managed Security Foundation.

Frequently asked questions

Questions we hear before this engagement starts.

Do you replace our existing firewall hardware or software?

Not necessarily — we typically manage what you already have. If a change in platform is genuinely warranted, we'll discuss that with you directly rather than assuming it.

What access do you need to our firewall?

Access appropriate to the agreed scope is confirmed during onboarding — nothing more than what's needed to deliver the engagement.

What if we need an urgent change?

Urgent changes are handled through a defined escalation path agreed during onboarding, within the engagement's support model.

Is this the same as Managed Security Foundation?

Managed Security Foundation bundles this together with VPN and remote access management and recurring reporting. Choose this service on its own if firewall management is your specific need.

Will you touch rules without telling us first?

No — changes with any meaningful impact are reviewed and confirmed with you before they're made.
