A4: how do you configure WatchGuard Firebox for firewalls?

Apply 5 settings in WatchGuard Firebox: change the default passphrases, keep management off the External interface, enable MFA for administrators, document inbound policies and review policies at least annually. Together they provide evidence for A4.2, A4.2.1, A4.3, A4.9, A4.10, A4.11, A4.7, A4.8, A4.5 and A4.6.

Fireware Web UI and WatchGuard Cloud policies map to A4.2 to A4.11. A new Firebox ships with the passphrases readwrite (admin) and readonly (status), which A4.2 requires you to change. See the firewalls requirements for what the control asks.

  1. Change the default passphrases

    A4.2A4.2.1A4.3
    Fireware Web UI > System > Users and Roles > select admin, then status > Edit > enter a new passphrase of 12 characters or more > OK > Save
  2. Keep management off the External interface

    A4.9A4.10A4.11
    Firewall > Firewall Policies > WatchGuard Web UI and WatchGuard policies > From: Any-Trusted and Any-Optional only (remove Any-External, or replace it with a trusted IP alias)
  3. Enable MFA for administrators

    A4.11
    AuthPoint: add a Firebox resource; Fireware Web UI > System > Users and Roles > Add: select AuthPoint as the authentication server (Fireware v12.7 or higher)
  4. Document inbound policies

    A4.7A4.8
    Firewall > Firewall Policies > each inbound policy and SNAT action: give it a name that identifies the service, and record the business need, approver and date in your firewall register
  5. Review policies at least annually

    A4.5A4.6
    Firewall > Firewall Policies: check each policy against traffic logs or WatchGuard Cloud reports; disable unused policies and record the review

A5: how do you configure WatchGuard Firebox for secure configuration?

Apply 2 settings in WatchGuard Firebox: remove unused users and remove unused service policies. Together they provide evidence for A5.2, A7.3 and A5.1.

Remove unused admin accounts and policies for services you do not run. See the secure configuration requirements for what the control asks.

  1. Remove unused users

    A5.2A7.3
    System > Users and Roles > delete unused Device Management users
  2. Remove unused service policies

    A5.1
    Firewall > Firewall Policies > disable or delete policies for services you no longer use (for example old FTP or RDP policies)

A6: how do you configure WatchGuard Firebox for security update management?

Apply 2 settings in WatchGuard Firebox: upgrade Fireware OS and track WatchGuard PSIRT advisories. Together they provide evidence for A6.4, A6.1 and A6.4.2.

A6.4 names firewall firmware. Since the Fireware 2026.1 release, WatchGuard Cloud can flag Fireboxes running a Fireware version affected by known vulnerabilities, with a severity and a link to the WatchGuard security advisory. It does not install anything for you. See the security update management requirements for what the control asks.

  1. Upgrade Fireware OS

    A6.4AUTO-FAILA6.1
    Fireware Web UI > System > Upgrade OS: install the latest release for your model; or WatchGuard Cloud > Configure > Devices > Firmware Upgrades > device menu > Upgrade Firmware
  2. Track WatchGuard PSIRT advisories

    A6.4.2
    watchguard.com/wgrd-psirt/advisories: check at least weekly; record each critical or high advisory and the date you upgraded

A7: how do you configure WatchGuard Firebox for user access control?

Apply 2 settings in WatchGuard Firebox: one account per administrator and configure account lockout. Together they provide evidence for A7.2, A7.5, A7.8 and A7.10.

Named admin accounts with roles, and lockout on repeated failed logins. See the user access control requirements for what the control asks.

  1. One account per administrator

    A7.2A7.5A7.8
    System > Users and Roles > Add > Role: Device Administrator only where needed, otherwise Device Monitor
  2. Configure account lockout

    A7.10
    Fireware Web UI > System > Users and Roles > Account Lockout tab > Enable Account Lockout: Failed Login Attempts 10 or fewer, and set Users Locked Out For

A8: how do you configure WatchGuard Firebox for malware protection?

Apply 1 setting in WatchGuard Firebox: enable Gateway AntiVirus and WebBlocker on proxy policies. Together they provide evidence for A8.3.

Gateway AntiVirus and WebBlocker support A8.3. Devices still need their own protection for A8.1. See the malware protection requirements for what the control asks.

  1. Enable Gateway AntiVirus and WebBlocker on proxy policies

    A8.3
    Subscription Services > Gateway AntiVirus and WebBlocker > apply to the HTTP and HTTPS proxy policies

What evidence should you keep for the assessor?

Keep the 4 dated records listed below for WatchGuard Firebox. They back up your notes fields and are what an assessor asks to see if an answer needs clarifying.

The self-assessment does not upload screenshots, but the notes fields must describe how each control is met, and Cyber Essentials Plus checks the configuration directly. Keep them in one folder, dated, and refresh them before each annual renewal. If you want the settings checked against the question set before you submit, a gap analysis covers it.

  • Firewall policy export with descriptions.
  • Screenshot of the WatchGuard Web UI and WatchGuard policy From lists.
  • Device Management user list and the account lockout settings.
  • Fireware version and upgrade history.

Frequently asked questions

Not on a physical Firebox. The default WatchGuard Web UI policy allows management from Any-Trusted and Any-Optional only. FireboxV and Firebox Cloud allow Any-External by default for initial setup, and WatchGuard says to remove it afterwards. If Any-External or a broad alias is in the policy, A4.9 becomes a yes and you need a documented business need plus MFA or a trusted IP allow list for A4.11.

No single platform covers the whole assessment. Cyber Essentials applies to every in-scope device, cloud service and network boundary. This guide covers what this platform can evidence; you still need to answer the scope questions in A2 and cover any other devices, firewalls and cloud services you use.

The self-assessment is declarative. You answer the questions and write notes; screenshots are not uploaded. Keep them anyway. They let you answer the notes fields precisely, they speed up Cyber Essentials Plus, and they are what an assessor asks for if an answer needs clarifying.
