Managed Firewall and Threat Prevention Across Ireland

Most of what we do to protect a business network does not require someone standing in your server room. Firewall rules can be reviewed remotely. DNS filtering policies can be deployed without visiting. Endpoint hardening, SIEM agent installation, and threat monitoring all work over a secure connection. The hardware that needs to be physically present can be preconfigured and shipped.

This page is for businesses across Ireland (Northern Ireland and Republic of Ireland) and the UK who need proper threat prevention but do not have an in-house security team to manage it.

What We Do Remotely

Firewall review and configuration

We audit your existing router/firewall configuration: what rules are in place, what ports are open, whether IDS/IPS is enabled, whether default credentials have been changed, and whether the firmware is current. Most business routers we audit for the first time have default admin passwords, no intrusion prevention enabled, and all traffic flowing through a single flat network with no segmentation.

After the review, we either reconfigure your existing hardware or recommend a replacement if it cannot support the features needed. Configuration is applied remotely through the management interface.

DNS threat filtering

We deploy DNS-level filtering that blocks malicious domains before any connection is made. This works network-wide (protecting every device including phones, IoT, and guest devices) or per-device using a lightweight agent for remote workers.

• Malware, ransomware, and phishing distribution domains blocked
• Command and control (C2) servers blocked (compromised devices cannot phone home)
• Newly registered domains flagged (most legitimate services do not use brand new domains)
• Advertising and tracking networks blocked (reduces attack surface)
• Category-based filtering available (adult content, gambling, social media during work hours)
• Full query logging showing every DNS request from every device

For businesses in Northern Ireland with our full onsite deployment, DNS filtering runs on a self-hosted server blocking 2,000,000+ domains. For remote-only customers, we deploy cloud-based DNS filtering with the same category coverage, managed centrally from our dashboard.

IDS/IPS configuration

If your router supports intrusion detection and prevention (most business-grade routers do, it is just not enabled), we turn it on and configure it properly. This means traffic is monitored for known attack patterns and blocked automatically, rather than just passing through unchecked.

Endpoint hardening

For each Windows device, we can remotely configure:

• BitLocker disk encryption enabled and verified
• Windows Defender real-time protection, cloud-delivered protection, and tamper protection confirmed on
• Controlled Folder Access (ransomware protection) enabled
• SMBv1 disabled (the protocol used by WannaCry and NotPetya)
• UAC set to highest level
• Browser hardening (SmartScreen, enhanced safe browsing, HTTPS forced)
• Windows Update verified current
• Local account audit (admin vs standard user, stale accounts removed)

Email security

SPF, DKIM, and DMARC configured on your domain so that nobody can send emails pretending to be your business. DMARC enforcement rolled from p=none through to p=reject over a monitored period. DNSSEC enabled where the DNS provider supports it.

Ongoing monitoring

Once deployed, we monitor the systems remotely:

• DNS filtering dashboard reviewed for blocked threats and unusual patterns
• Endpoint health verified (Defender active, encryption on, updates current)
• Firewall logs checked for blocked intrusion attempts
• Monthly summary provided: what was blocked, what was flagged, and any recommendations

What Needs to Be Onsite

Some things require physical presence:

• Router/firewall hardware installation - if a new device is needed, we ship it preconfigured. For Northern Ireland, we install onsite. For Republic of Ireland, we can ship preconfigured with instructions or arrange installation as coverage expands.
• On-premises DNS filtering server - the full self-hosted stack (blocking 2M+ domains with local query logging) requires a physical device onsite. We can ship this preconfigured.
• Network cabling and VLAN configuration on switches - physical network segmentation requires onsite access to switches and patch panels.

Everything else (firewall policy, DNS filtering rules, endpoint configuration, email security, monitoring) is remote.

Who This Is For

• Businesses without an IT security person who need proper protection in place
• Companies that have a firewall but nobody has reviewed the rules in years
• Businesses that have been phished, ransomwared, or breached and want it fixed properly
• Organisations needing Cyber Essentials or ISO 27001 evidence
• Remote and hybrid teams whose devices are not centrally managed or hardened
• Businesses across Ireland wanting managed security without hiring in-house

Where This Is Available

Remote services (firewall review, DNS filtering, endpoint hardening, email security, monitoring): available across Ireland and the UK. No geographic restriction.

Onsite installation (router deployment, server installation, network cabling): Northern Ireland. Republic of Ireland coverage expanding. Preconfigured hardware can be shipped anywhere.
