Lab status: online

WB Security
builds it. breaks it. detects it.

Practical, affordable cyber security for small and medium UK businesses — from a self-built lab of isolated networks, Windows & Linux targets, and a live SIEM used to run real attacks and prove they get caught.

03 — Engagements

Services / built for small & medium UK businesses

Security Assessment

£110/ engagement

A hands-on review of your business network — Wi-Fi, firewall rules, exposed services, and weak credentials — with a plain-English report of what to fix first.

  • External + internal scan of your network
  • Findings ranked by risk (critical → low)
  • Written report with clear remediation steps

SIEM / Logging Setup

£180/ setup

Get a Wazuh-based monitoring stack deployed for your business — so you can actually see what's happening on your network instead of finding out after the fact.

  • Wazuh install & agent deployment
  • Sysmon / auditd configured on your hosts
  • Starter alert rules tuned to your environment

Security Consultation

£45/ hour

Not sure where to start? A one-on-one call to talk through your specific concerns — from "is this email a scam" to planning a bigger security project.

  • 30-min free intro call before booking
  • Remote, screen-share friendly
  • Follow-up notes emailed after the call

Case studies / attack → detect → remediate

CRITICAL

Domain Admin via Kerberoasting

Active Directory · full attack chain

Objective

Go from an unprivileged domain foothold to Domain Admin without triggering a response.

Attack

Enumerated the domain with BloodHound, identified a service account with a weak password, extracted its Kerberos ticket, and cracked it offline.

Detection

Wazuh flagged abnormal TGS request volume from a single host (Sysmon Event ID 4769) and correlated it with BloodHound-style LDAP enumeration.

Remediation

Rotated the service account to a 30-character managed password and re-ran the attack — ticket cracking became computationally infeasible within the test window.

SQLi to Shell on a Vulnerable Web App

Linux target · OWASP Top 10

Objective

Assess a deliberately vulnerable web app for injection flaws and chain them into remote code execution.

Attack

Found an unsanitized login field, used a UNION-based SQL injection to dump credentials, then leveraged a file-upload flaw for a reverse shell.

Detection

auditd captured the unexpected child process spawned from the web server, forwarded to Wazuh, which fired a "web shell behaviour" rule.

Remediation

Added parameterized queries and a file-type allowlist on uploads; confirmed the same payloads were rejected on re-test.

Ransomware Tabletop & IR Walkthrough

Windows target · incident response

Objective

Simulate a ransomware detonation and practice the full IR lifecycle end to end.

Attack

Executed a benign file-encryptor proof-of-concept against a snapshot of the Windows VM to mimic ransomware behaviour safely.

Detection

Wazuh's File Integrity Monitoring flagged mass file modification within seconds; Sysmon showed the parent process tree.

Remediation

Documented containment, eradication, and recovery steps, then wrote a runbook for future incidents.

05 — Feedback

What clients say / small & medium UK businesses

Example reviews shown for illustration — replace with genuine client feedback once available.

"The assessment found a misconfigured firewall rule our previous IT contractor had missed for years. Clear report, no jargon, fixed within a week."

Fiona Marsh

Operations Director, Independent Retail Business — Bristol

"We move stock for a dozen retailers and couldn't afford downtime. The penetration test on our logistics portal found a real access control flaw before it became a real problem."

Daniel Osei

IT Manager, Supply Chain & Logistics Firm — Leeds

"As a small shop we assumed we weren't a target. The consultation call was honest about what actually mattered for a business our size, without trying to oversell us."

Priya Chandra

Owner, Homeware Retail Shop — Leicester

"The SIEM setup meant our overnight warehouse systems are finally monitored properly. We got an alert about unusual login activity within the first fortnight — it worked exactly as promised."

Graham Ainsley

Warehouse Systems Lead, Wholesale Distribution Business — Manchester

"Straightforward, well-documented, and reasonably priced compared to the bigger consultancies we spoke to first. Exactly what a growing business needs."

Louise Fairweather

07 — Build log

How the lab came together

Week 1

Network foundation

Hypervisor installed, pfSense deployed as the isolated network's edge.

Week 2

Targets stood up

Windows Server + AD and a Linux target provisioned and baseline-hardened.

Week 3

Telemetry & SIEM

Sysmon and auditd deployed, logs forwarded into a new Wazuh instance.

Week 4

First attack chain

Kali box added; ran and documented the Kerberoasting case study above.

Week 5+

Detection engineering

Wrote custom rules, mapped every finding to MITRE ATT&CK, published write-ups.
