The Threat Landscape

The numbers don't lie

Cyber attacks are increasing in frequency, sophistication, and cost. Most organisations are underprepared.

Real-World Scenarios

Could this happen to you?

These aren't hypotheticals. They're composites of real incidents we've responded to — anonymised, but accurate.

LEGAL

A partner clicked a link. The firm lost £2.1M.

A senior partner opened a convincing phishing email impersonating a client. Attackers gained access to the M&A deal room and redirected a completion payment to a fraudulent account.

No phishing training. No email filtering. No incident plan.

FINANCE

Ransomware hit on a Friday evening. Systems down for 11 days.

A fintech firm with 150 staff discovered ransomware had encrypted their production databases and backups. With no incident response retainer, they scrambled for help while the clock ticked on regulatory notification.

No endpoint detection. No network segmentation. No tested backups.

HEALTHCARE

Patient records on the dark web. The ICO came calling.

A healthcare provider's unpatched VPN appliance was exploited. Attackers exfiltrated 40,000 patient records before anyone noticed. The ICO investigation lasted 14 months.

No vulnerability scanning. No access monitoring. No patch management.

The Process

How an engagement works

Structured, transparent, and designed to give you clarity at every stage. It starts with a free call — no commitment, no sales team.

01

Free consultation

A 30-minute call with a senior consultant. No sales team. We learn your business, risk profile, and compliance obligations.

02

Scoping & proposal

We define the engagement — scope, methodology, timeline, and cost. You approve before anything begins. No surprises.

03

Assessment & delivery

Our team executes the engagement — typically 2–4 weeks for an audit. You get regular updates throughout.

04

Report & roadmap

A clear, actionable report. Executive summary for the board, technical detail for your team, and a prioritised remediation roadmap.

Deliverables

What you walk away with

Every audit produces tangible, actionable outputs — not vague advice. Here's exactly what you get.

Executive Risk Report

Board-ready summary of your security posture, risk exposure, and recommended actions — written in plain language, not jargon.

Technical Findings

Detailed vulnerability analysis with severity ratings, evidence, and reproduction steps — everything your technical team needs to act.

Remediation Roadmap

Prioritised action plan — what to fix first, what can wait, and estimated effort. Designed so you can brief your team or hand it to us.

Compliance Gap Analysis

Where you stand against ISO 27001, Cyber Essentials, and your sector's regulatory requirements — with specific gaps and fixes.

Live Debrief

A face-to-face or video walkthrough of every finding with the consultant who ran the assessment. Ask questions, challenge findings, plan next steps.

Retest Window

Fix the critical issues, and we retest to confirm they're resolved. Included in every audit — no additional charge.

Common Questions

Questions we hear often

"We're too small to be a target."

Small and mid-market businesses are the primary target. 43% of UK businesses experienced a breach last year, and attackers increasingly target organisations with weaker defences as a stepping stone to larger supply chains. Size doesn't determine risk — visibility does.

"We already have antivirus and a firewall."

Perimeter tools are necessary but nowhere near sufficient. Modern attacks bypass traditional defences through phishing, credential theft, and supply chain compromise. An audit reveals the gaps between what you think you're protected against and what you actually are.

"We can't afford a full audit right now."

The average cost of a UK cyber breach is £10,830 for medium businesses — and significantly more in regulated sectors when fines and reputational damage are factored in. A consultation is free, and we scope engagements to fit your budget and priorities.

"We don't have an IT team to implement the recommendations."

That's exactly what our managed cybersecurity service is for. After the audit, we can implement and manage the remediation roadmap end-to-end — so you get enterprise-grade security without hiring a single engineer.

"How long does an audit take?"

Typically 2–4 weeks from scoping to final report, depending on the size and complexity of your environment. The assessment itself is minimally disruptive — most of it happens remotely with scheduled on-site time where needed.

"Will you try to upsell us on managed services?"

Our methodology is audit-first. The report is yours — it's an honest assessment with no strings attached. If managed services make sense, we'll say so. If they don't, we'll say that too. Many clients take the report and act on it independently.
