Antivirus waits to recognise an attack. Your immune system doesn't.

We're on a mission to protect the unsung heroes of the business world: small and mid-sized enterprises. Adaptive detection, a named team behind it, and security made affordable and accessible to businesses of all sizes.

The problem

Small businesses aren't missed by attackers. They're overlooked — and that's the point.

A silent breach at a large organisation is an overt disruption at a small one. The difference isn't the attacker — it's that the enterprise has a security team and the small firm has whoever is free that afternoon.

The tools built for that enterprise don't transfer down. They're priced per seat for organisations with thousands of seats, they need multiple licences to cover one business, and they assume a trained analyst is watching the console. Most small firms have none of those things.

So small and mid-sized businesses fall victim precisely because they're overlooked. We're here to change that.

Our approach

Your body already solved this problem.

The immune system is the most versatile defence ever created — nature's most sophisticated security system. It doesn't work from a list of known threats. It learns what belongs, detects what doesn't, contains the intrusion locally, and remembers the encounter so the next response is faster.

Signature-based security does the opposite: it recognises attacks it has already seen and misses everything else. That gap is where breaches live.

So we built Cytorix — cybersecurity 2.0, adaptive and intelligent. Multiple AI agents detect, verify and respond in layers, containing a threat in under a minute. It's a digital defence that grows stronger with every encounter, rather than waiting on the next definition update.

That engine is why a small team can watch a lot of clients properly. Cytorix handles what's routine, so your people — and ours — focus on what isn't.

01

Recognise self

Rather than memorising every known threat, the system learns what normal looks like in your environment — and treats the unfamiliar as suspect by default.

02

Contain locally

An unrecognised process is isolated where it lands. No lateral movement while a queue waits for an analyst to reach the alert.

03

Remember

Every encounter sharpens the response. Protection improves through exposure instead of waiting on the next definition update.

What we do

Three engagements, priced so a fifteen-person company can say yes.

Enterprise security assumes thousands of seats, several licences, and a trained analyst watching a console. Most businesses have none of those. We bring the analyst, choose the tooling that fits, and charge for the outcome rather than the seat count.

01

Every day, not just at install

Security you don't have to run yourself

Retainer, scoped to headcount

Most small firms can't hire a security analyst — the salary alone exceeds the entire IT budget. So we select the right endpoint platform for your environment, deploy it properly, tune it so the alerts mean something, and then actually watch it.

That means 24/7 monitoring, incident response when something real lands, and a named team that knows your environment — not a queue that re-reads your history every time. Where our own tooling fits we use it; where your insurer or largest client names a vendor, we deploy and manage that instead. Vendor-selected, not vendor-locked.

02

Before an auditor or an attacker does

Find out what's actually exposed

Fixed-fee assessment

We map what you really run — devices, identities, cloud tenants, and the shadow IT nobody documented — and tell you where you're exposed, ranked by what would hurt most rather than by what scores highest on a scanner.

Then we close the gaps in that order: baseline hardening, identity and access, backups verified by restoring them rather than trusting a green tick. You get documentation you can hand to a client, an insurer, or an auditor — because security work that can't be evidenced doesn't count when someone asks.

03

When it has already happened

Establish what actually occurred

Fixed-fee, per incident or per cohort

After an incident the expensive question isn't what broke — it's whether you can say, with evidence, how they got in and what they touched. Guessing costs you the insurance claim and the client.

Our lab works your endpoints, servers, and affected cloud infrastructure to establish root cause. And because the way in is usually a person rather than a port, we train yours — phishing awareness, password practice, and safe data handling, pitched separately for technical and non-technical staff.

Cloud & infrastructure

Azure architecture, migration, backup and disaster recovery.

Integration & custom software

APIs, automation, and internal tooling where off-the-shelf falls short.

Hardware & endpoint lifecycle

Procurement through decommission — devices arriving configured, encrypted, and enrolled.

Managed IT support

Helpdesk, patching, vendor coordination, onboarding and offboarding.

Technology

Vendor-selected, not vendor-locked.

The right stack for a fifteen-person firm is rarely the right stack for a two-hundred-person one. We pick per environment — including the platforms your insurer or your largest client names in a contract.

Endpoint detection & response

Enterprise-grade EDR selected, deployed, tuned, and monitored on your behalf — including the platforms your insurer or your largest client insists on.

Microsoft 365 & Azure

Entra ID, Defender, Intune, and cloud architecture. We run production workloads on Azure ourselves, not just for clients.

Network & perimeter

Firewalls, segmentation, VPN, and site-to-site connectivity.

We select tooling per environment rather than reselling a single stack by default.

Our software

Built on the same idea.

Everything we learn securing businesses goes back into our own platform — adaptive detection built on the immune-system model, priced for the firms enterprise tooling leaves out.

Cytorix

Our bio-inspired detection engine. Multiple AI agents detect, verify and respond in layers the way an immune system does — containing a threat in under a minute and getting sharper with each one. It's what lets us cover a client without a room full of analysts.

Endpoint Protection

Runs as a background service on each machine, watching file, port and process activity and checking hashes against our threat database. We manage devices and tune rules from the portal, so you're not the one reading alerts.

AI Phishing Defense

A browser extension that scores every URL a user visits against a machine-learning model, catching the malicious page before the click lands. Deployed as part of the endpoint rollout.

Malware Monitoring

Real-time inspection of incoming files against the same detection database, so nothing reaches a machine unexamined.

Who we are
