Network Security & SD-WAN

Secure paths between your sites, without the MPLS invoice

Traffic between your offices, your cloud and your staff gets encrypted, steered and filtered — on hardware you own and policies we maintain. No appliance you have to log into, no licence cliff in three years.

What's included

What you actually get

Not a feature list assembled from datasheets — the work we do on every network security & sd-wan project, including the parts that get skipped when somebody is in a hurry.

Site-to-site VPN or SD-WAN fabric

Encrypted links between offices with automatic failover across whatever circuits you have, so the second internet connection is doing something useful instead of nothing.

Application-aware steering

Voice and video take the cleanest available path; bulk backups take the cheap one. That is the practical difference between SD-WAN and two routers with a VPN tunnel.

Firewall and routing done properly

Rule sets that are readable six months later, no wildcard any-any, and a documented change history. Most breaches that reach a small business network pass through a rule somebody added quickly in a hurry.

Network segmentation

Point of sale, CCTV, guest and corporate traffic separated, so one compromised device is a contained problem rather than a starting point.

Secure remote access

Per-user VPN or Zero Trust access with multifactor in front of it, replacing the shared pre-shared key that half the team knows.

Content and threat filtering

Category filtering, DNS-level blocking and updates applied on a schedule you approve, not silently whenever a device feels like it.

Who it suits

If any of these sound like you

Multi-site businesses still paying for MPLS between offices
Companies with a single broadband link and no redundancy at all
Businesses with remote or hybrid staff accessing internal systems
Anyone whose cyber insurance renewal asks about MFA, segmentation and patching

How it works

Four steps, no surprises

1
Risk walk-through
What is exposed to the internet now, what would hurt most if it went down or out, and what your insurer actually requires. On-site if you want it.
2
Design to the sites you have
Circuit inventory, throughput expectations, device count and growth. The design is the same standard whether it is two sites or twelve.
3
Staged rollout
Hub and policy first, then one pilot site, then the rest. Each stage reversible, and never on a Friday afternoon.
4
Ongoing policy management
Firmware, rule review and change records, so the security posture does not quietly decay once the project is finished.

Questions

The things people ask first

Is SD-WAN actually safer than a traditional VPN?

They solve different problems. A hub-and-spoke VPN connects sites; SD-WAN manages several paths per site, steers traffic by application and fails over automatically. Security comes from what you run on top — encryption, segmentation, filtering — which is included rather than bolted on.

We have MPLS and it works. Why change?

Sometimes you should not. MPLS is predictable and you may be mid-contract. Where it stops making sense is when your applications have moved to the cloud and MPLS hairpins all that traffic through another data centre. That is a cost and latency problem, not a reliability one.

Do we need a firewall appliance at every site?

Usually one capable gateway per site, yes — that is where segmentation and filtering live. Cloud-managed gateways keep the paperwork down and make a new site a configuration exercise rather than a truck roll.

Can you help if we have already had an incident?

Yes, and quickly — call rather than email. Contain first, understand second, rebuild third. Retaining the evidence matters, so avoid wiping anything before we talk.

Does this replace our antivirus?

No, it is a different layer. Antivirus looks after endpoints; this controls what is allowed in and out of the network and what can talk to what inside it. You want both.
