Reliable business networks, secure Wi-Fi and connected locations

Your network underpins business services. Unreliable connections interrupt calls, cloud services, tills, printing, video meetings and access to servers. An overly open network can allow a guest or infected device to reach systems it should not access.

Nemis designs, deploys and maintains networks around reliability and security. We begin with how your business works, independently of any single equipment brand.

When connectivity becomes a business responsibility

This service is suited to office moves and refurbishments, new locations, Wi-Fi problems, remote working or separating business, guest and technical devices.

You do not need to wait for a complete overhaul. We clarify the current state, address the most important issues and then add capabilities. This prevents risks and manual work from accumulating while keeping technology tied to specific business needs.

LOCATIONS

Opening or connecting a location

For a new office, warehouse or branch, we plan connectivity, segmentation, access and responsibilities before the first working day.

WI-FI

Wireless problems interrupt work

Coverage, user density, interference and network separation need a measurable assessment rather than random restarts.

REMOTE WORK

Connections lack clear boundaries

Remote users and locations need secure, limited and documented access to the services they actually use.

Does your network support work or cause more interruptions?

Whether something currently works is only part of the picture. We also consider documentation, recoverability, access rights and behaviour during a change or outage. The initial assessment focuses on business impact as well as devices.

WI-FI

Wi-Fi keeps dropping

Problems are handled with random restarts rather than measurements of coverage, load, interference and the underlying cause.

SEGMENTS

Every device shares the same network

Guests, cameras, servers, users, IoT devices and management systems have unnecessary access to one another.

LOCATIONS

Connections between sites are not monitored

Branches, home workers and cloud services are connected without clear rules, monitoring or documentation.

RULES

The firewall is a history of exceptions

Old rules lack a clear purpose, owner or review, increasing risk and complexity.

DOCUMENTATION

VLANs, addresses and VPNs are not documented

During changes, outages or supplier replacements, people must reconstruct the setup from memory and screenshots.

ACCESS

Remote users have excessive access

Connecting to the network should not automatically grant access to every server, camera and business service.

PRIORITIES

Critical services have no priority

Voice, video meetings, tills and production services compete for connectivity without clearly defined priorities.

Your network as a managed business system

For each area, we first assess how your business works today and what is genuinely critical. We then identify the smallest useful action that reduces risk or improves reliability. Features are introduced for a purpose rather than simply because a product offers them.

Supported platforms may include MikroTik, Fortinet, OPNsense/pfSense, OpenWrt, Omada and UniFi. Selection depends on requirements, your environment, budget and future maintenance. No brand is chosen for its own sake.

We consider people, processes, existing equipment, maintenance costs and whether another responsible person could understand the solution. The outcome must be verifiable: we agree what success means, how to check it and where essential settings are documented.

ASSESSMENT

Topology and documentation

We review connections, address ranges, VLANs, DHCP, DNS, Wi-Fi, firewalls and critical applications. This creates a clear overview of dependencies and responsibilities.

SEGMENTATION

VLAN segmentation

We separate users, servers, guests, cameras, IoT devices and management access according to actual needs, limiting unnecessary traffic and the spread of incidents.

WI-FI

Business Wi-Fi

We plan coverage, capacity, access points, guest networking and access management so that wireless connectivity remains usable as your team grows.

BOUNDARY

Firewalls

We review the network boundary, exposed services, rules and exceptions. Each rule should have a purpose, an owner and a way to verify it.

VPN

VPN connections

We deploy or improve IPsec, WireGuard, OpenVPN or another suitable VPN solution for connected sites and remote users.

MONITORING

Monitoring and resilience

We monitor availability, key connections, errors and basic equipment health to spot some problems before work is interrupted.

MIGRATION

Moving to new equipment

When replacing switches, access points, routers or firewalls, we prepare the sequence, verification and rollback approach.

APPLICATIONS

Aligning with applications

We assess requirements for voice, video calls, servers, cloud services, tills and other critical applications so that the network does not become a hidden bottleneck.

A physical business network with separate segments, Wi-Fi and VPN connections

Separate paths for business, guests and technical systems

Segmentation gives guest devices different access from servers, cameras and managed business equipment. It also helps contain the consequences of faults, infections or incorrectly configured permissions.

A secure VPN connects each location or remote user only to the services they need. Access, addresses, rules and responsibilities are documented so that later changes can be checked and safely restricted when necessary.

CLEAR BOUNDARIES

Useful access is understandable and manageable

The best connection does not necessarily provide the broadest access. Permissions should match business needs, rules should have a clear purpose and the business should know who can approve changes.

More predictable connectivity that is easier to manage

Good delivery makes key services more predictable, allows problems to be resolved using evidence and helps the business understand its decisions. This reduces dependence on individuals, shortens troubleshooting and enables more realistic cost planning.

Topology, segments, access rights and essential decisions remain available to the person responsible when changes, outages or supplier discussions arise. This documentation is part of delivery.

When network decisions reflect everyday business operations, changes bring fewer surprises. Users get more reliable connectivity, management sees clearer priorities and the technical team can expand, verify and hand over the environment sensibly.

STABILITY

More reliable work

Voice, cloud services, printing, video calls and servers have a more dependable foundation, reducing unexpected interruptions.

CONTAINMENT

Less spread of incidents

Separate segments reduce unnecessary connections between devices and limit the impact of an issue on other parts of the environment.

REMOTE ACCESS

Safer remote access

VPNs and access rules connect users and locations to agreed services without excessive exposure.

DOCUMENTATION

Faster troubleshooting

Documented connections, VLANs, addresses and responsibilities shorten diagnosis and simplify supplier coordination.

GROWTH

A foundation for growth and new locations

Clear topology and standards make it more predictable to add users, access points, locations and applications.

EXPOSURE

Fewer unnecessarily exposed services

We review rules and exposed connections against their actual purpose, reducing outdated exceptions and unnecessary access.

We plan, verify and document changes

We start by defining the business goal, scope, dependencies and constraints. We review the current state, available documentation and points where a change might affect users or data before making changes in production.

For larger changes, we prepare a sequence, maintenance window, verification process and rollback approach. You know what is changing, why and how the result will be confirmed before the upgrade starts.

1. GOAL

Business impact and scope

We identify critical services, users, locations, dependencies and the consequences of an outage.

2. ASSESSMENT

Current state and priorities

We review the actual topology, documentation, constraints and points that need priority action.

3. IMPLEMENTATION

Approved changes, delivered in stages

For larger changes, we prepare the sequence, maintenance window, verification process and a rollback option.

4. FOLLOW-UP

Monitoring and next steps

After implementation, we update documentation and separate urgent actions from important improvements and work that can wait.

The quickest safe intervention when appropriate

Remote support is our usual way of working. Secure, documented access lets us check status, logs, configurations, permissions and diagnostic information without waiting for a visit.

Physical replacement, measurements, cabling, local recovery, Wi-Fi coverage surveys or security restrictions may require on-site work. We choose the approach that delivers the right result.

RESPONSIBLE DELIVERY

Quality delivery includes verification and clear boundaries

After implementation, we verify the agreed result and update documentation where needed for future maintenance. We clearly identify what is included and what requires a separate project, licence, supplier or partner. Changes that could significantly affect availability, data or costs require approval.

Networks, Wi-Fi and VPNs: frequently asked questions

For an initial assessment, useful details include the number of users or locations, a floor plan or description of the premises, key applications, existing equipment and the issue you want to address first.

Do you offer MikroTik solutions?

Yes, alongside other options. We select the platform according to business requirements, the existing environment, available support, budget and future maintenance.

Why use VLANs?

VLANs restrict unnecessary traffic and access between parts of the network. Business users, guests, cameras, IoT devices, servers and management systems are separated according to actual needs.

Does Wi-Fi require a site survey?

A visit, floor plan or measurement is recommended for reliable business coverage. This is especially important for larger premises, warehouses, difficult wall materials and higher user numbers.

Will an upgrade require downtime?

We prepare a gradual migration and schedule critical changes at an agreed time. For larger work, we define verification and a rollback approach if the result is not as expected.

Can you connect multiple locations and remote users?

Yes. We deploy or improve an appropriate VPN and access rules for sites and remote users, restricting access to the business services they need.

Start with the connections your business depends on

Describe your company size, number of users or locations, main services and current issue. Tell us whether this is urgent, a planned upgrade or a new location. We will suggest an assessment, project approach or ongoing support arrangement.
