Our Services

What We Deliver

From initial threat modelling through to remediation and ongoing advisory, we cover your security posture end to end.

Security Architecture Review

Analysis of your network topology, identity and access management, cloud configuration, and endpoint controls to identify structural weaknesses and design improvements.

Zero Trust IAM Cloud

Threat Modelling

Structured STRIDE and MITRE ATT&CK-based analysis of your systems to identify adversary entry points, attack paths, and the most likely threats to your business.

STRIDE MITRE ATT&CK

Security Strategy & Roadmap

A prioritised, multi-year security improvement roadmap aligned to your business objectives, budget constraints, and risk appetite, not a generic best-practice checklist.

Advisory Roadmap

Incident Response Planning

Development and review of incident response plans, playbooks, and runbooks, ensuring your team knows exactly what to do when a breach occurs, not after.

IR Plan Playbooks

Third-Party & Supply Chain Risk

Assessment of vendor security posture, third-party access controls, and supply chain dependencies, identifying the risks that enter your environment through others.

Vendor Risk Supply Chain

Executive Security Briefings

Board and C-suite ready reporting that translates technical risk into business impact, giving leadership the clarity they need to make informed investment decisions.

Framework-Based Assessment

Risk Assessments Grounded
in Leading Frameworks

We do not invent our own methodology. Our risk assessments are structured against recognised industry frameworks, ensuring findings are rigorous, defensible, and comparable to your peers and regulators.

Each assessment produces a risk register with likelihood and impact ratings, a heat map, and a prioritised remediation plan, giving you a clear picture of your residual risk and the highest-value actions to take first.

NIST CSF 2.0 Govern · Identify · Protect · Detect · Respond · Recover

The gold standard for cybersecurity programmes. We assess your maturity across all six functions and produce a tier rating with targeted uplift recommendations.

ISO 27001:2022 Annex A Control Assessment

Comprehensive gap analysis against ISO 27001 Annex A controls, identifying non-conformities, supporting certification readiness, and informing your Statement of Applicability.

CIS Controls v8 Implementation Groups 1-3

Prioritised, prescriptive controls mapped to your environment size and risk profile. Particularly effective for organisations building a programme from the ground up.

Simulation Exercises

Tabletop Exercises (TTX)

Plans are only as good as the people executing them. Our facilitated tabletop exercises put your incident response capability under realistic pressure, without the consequences of a real breach.

Ransomware Response

Simulate a ransomware deployment across your environment, testing detection speed, escalation paths, communication protocols, and recovery decision-making under pressure.

Business Email Compromise

Walk your finance, HR, and IT teams through a realistic BEC scenario, validating verification processes, approval workflows, and inter-team coordination when fraud is suspected.

Third-Party Breach Scenario

Simulate a compromise originating from a key supplier or managed service provider, testing your ability to isolate, investigate, and respond when the threat enters through a trusted third party.

Data Breach & Regulatory Notification

Exercise your legal, compliance, and communications response to a personal data breach, including GDPR/ICO notification timelines, customer communication, and board escalation.

How a TTX Engagement Works

01
Scoping & Scenario Design
We work with you to select scenarios that reflect your real threat landscape. Scenarios are tailored to your sector, technology stack, and team structure.
02
Facilitated Exercise
B5 Cyber facilitates the session, introducing injects, probing decision-making, and observing team dynamics across technical, management, and comms functions.
03
Hot Wash & Immediate Feedback
Immediately after the exercise, a structured debrief surfaces what worked, what did not, and what gaps need urgent attention.
04
After-Action Report
A detailed written report documenting observations, gaps identified, and a prioritised action plan to improve your incident response capability.
