Two layers, one strategy
Good security is boring. It doesn't rely on staff spotting a cleverly faked email or on luck. It relies on layers: a firewall that inspects everything crossing your network boundary, and endpoint protection that watches what runs on every machine inside it. An attack has to beat both — and beating both is rare.
That's the strategy behind our network security offering. Bitdefender EDR & ATS guards the endpoints your people work on; a Zyxel firewall guards the single door everything passes through. Each layer catches what the other can't.
The threat has changed fundamentally in the last few years. Attackers use AI to write flawless phishing emails in seconds, to clone a director's voice from a minute of audio, and to produce malware that rewrites itself so no signature ever matches. Defences built for the pre-AI era simply weren't designed for this.
Neither layer works as a set-and-forget box, though — protection that's installed and ignored quietly rots. Every deployment we deliver is monitored and managed by YBS engineers as part of your contract, so detections are investigated, updates are applied, and your security posture improves over time rather than decaying.
Bitdefender GravityZone
The Bitdefender EDR & ATS package
We deploy Bitdefender GravityZone with Endpoint Detection & Response (EDR) and Advanced Threat Security (ATS) across your workstations, laptops and servers.
What is EDR?
Endpoint Detection & Response watches what is actually happening on every workstation, laptop and server — processes, file changes, network connections — rather than just scanning files against a list of known viruses. When it sees behaviour that looks like an attack (a document spawning a script, a process encrypting files in bulk), it steps in, isolates the device and rolls back the damage.
What is ATS?
Advanced Threat Security adds the layers that stop attacks before they ever execute: machine-learning detection of never-before-seen malware, sandbox analysis that detonates suspicious files safely in the cloud, and exploit prevention that blocks the techniques attackers use to weaponise everyday software.
Behaviour over signatures
Traditional antivirus asks “have we seen this file before?” — which fails the first time a new strain appears. EDR asks “is this behaving like an attack?” — which catches brand-new threats, fileless malware and living-off-the-land attacks that signature scanners never see.
Automatic containment
When Bitdefender detects an active attack it can isolate the affected machine from the network in seconds, automatically. One infected laptop stays one infected laptop — instead of becoming a business-wide incident by lunchtime.
Why Bitdefender
A Gartner-recognised leader, in an AI threat landscape
Endpoint protection is not the place to take a chance on an unknown brand. Here's why Bitdefender is the one we put our name behind.
Built for the age of AI attacks
Attackers now use AI to generate flawless phishing emails, deepfake voice calls and malware that rewrites itself to avoid detection. Defending against machine-speed attacks needs machine-speed defence — Bitdefender's own AI models are trained on telemetry from over 500 million protected endpoints worldwide, so a new attack seen anywhere is blocked everywhere.
A recognised industry leader
Bitdefender is consistently named a Leader in the Gartner® Magic Quadrant™ for Endpoint Protection Platforms and posts some of the highest scores in independent AV-TEST and AV-Comparatives evaluations year after year. You're not trusting a startup's marketing — you're trusting independently verified detection rates.
Light on the machine
Enterprise-grade protection that users don't notice. Bitdefender is engineered to run quietly in the background without the slowdowns that make staff beg to have antivirus removed — which matters, because protection only works when it stays switched on.
Managed by us, not by you
We deploy, license, monitor and respond. Alerts land with YBS engineers — not in an inbox nobody reads — so detections are investigated and dealt with rather than becoming tomorrow's breach report.
Perimeter defence
Why every business needs a proper firewall
If your network connects to the internet — and it does — something has to decide what traffic is welcome. That something should be a business-grade firewall, not an afterthought.
One door, properly guarded
Every packet entering or leaving your business passes through the firewall. It's where you enforce what is allowed in, what is allowed out, and what gets blocked on sight — the single most effective control point a business network has.
Stops the quiet attacks
The most damaging breaches aren't loud. They're a remote access attempt on an open port at 3am, or an infected device quietly calling home. A properly configured firewall sees and stops that traffic before it becomes an incident.
Keeps networks separated
Guest Wi-Fi, staff devices, servers and CCTV should not all share one flat network. Firewall rules and VLANs keep them apart, so a compromised visitor laptop can't wander into your accounts data.
Insurance & compliance
Cyber insurers increasingly ask one question before anything else: do you have a business-grade firewall, properly managed? A consumer router with a sticker password is no longer a passable answer.
Firewall vs. router — what's the difference?
The box your broadband provider sent is a router. It connects you to the internet — but connecting and protecting are two different jobs.
What it is
ISP router
A router's job is to move traffic between your network and the internet. It routes — security features are minimal and often switched off by default.
Business firewall
A firewall's job is to inspect that traffic and decide what is allowed through. Routing is included — security is the point.
Threat inspection
ISP router
Basic NAT hides internal addresses, but there's no deep packet inspection, no intrusion prevention and no malware filtering on the traffic itself.
Business firewall
Deep packet inspection, intrusion prevention (IPS), gateway antivirus and content filtering examine the actual content of connections, not just where they're headed.
Visibility & control
ISP router
Little or no logging. If something suspicious happened last Tuesday, there's no record to check and no alert raised.
Business firewall
Full traffic logging, alerting and reporting. You can see exactly what tried to get in, what was blocked, and prove it to an insurer or auditor.
Business features
ISP router
One flat network, limited VPN support, and no way to apply different rules to staff, guests and servers.
Business firewall
VLANs, site-to-site and remote-access VPN, per-group policies, web filtering and bandwidth control — the toolkit a real business network needs.
Zyxel USG FLEX
Zyxel firewalls, managed by YBS
Zyxel is one of our long-standing partners, and their USG FLEX range is our go-to for SME perimeter security.
Right-sized for SMEs
Zyxel's USG FLEX firewall range delivers genuine enterprise protection — IPS, gateway anti-malware, web filtering and application control — at a price point that makes sense for a 5-to-100-person business, without the licensing maze of bigger enterprise brands.
Cloud-managed
Zyxel's Nebula cloud platform means we can monitor, update and reconfigure your firewall remotely, the moment something needs attention — no site visit required for the routine work, and firmware security updates are kept current.
Always-current protection
Live threat intelligence feeds update the firewall's blocklists continuously. New malicious domains, botnet command servers and exploit signatures are pushed to the box automatically — protection that keeps pace without anyone lifting a finger.
Supplied, installed & managed
We specify the right model for your connection speed and user count, install it, migrate your settings, and manage it as part of your contract. You get the protection; we carry the pager.
