Third Party Cyber Risk Management

Third Party Risk Management (TPRM) has become one of the most critical ways to strengthen cyber resilience in 2026. Be it the debilitating Marks and Spencer attack, the devastating blow to Jaguar Land Rover or the SolarWinds supply chain attack - the common thread tying all of these major cybersecurity incidents was a compromise of a third-party.  

Today, your organisation’s security posture is truly only as strong as your weakest third party. From SaaS providers to outsourced vendors, every external relationship introduces risk. This is especially relevant where personal data, critical systems or operational dependencies are involved.

At Cyber Management Alliance (CM-Alliance), we provide independent, structured Third Party Risk Management (TPRM) that go far beyond checkbox compliance.

Our approach identifies real-world security gaps and evaluates regulatory exposure. By assessing vendor-provided data, we help you do all the heavy-lifting when it comes to assessing third-party risk. We deliver clear, actionable recommendations so you can make confident vendor on-boarding decisions.

Top Benefits of Third Party Risk Management

Clear Vendor Risk Visibility

Get a complete, structured view of your third-party security posture across governance, compliance and operational resilience. We highlight real risks so nothing critical is overlooked.

Confident Vendor Approvals

Make informed go/no-go decisions on vendors backed by expert analysis and a clear risk verdict. Eliminate uncertainty with evidence-driven recommendations.

Compliance Assurance

Ensure vendors meet UK GDPR, NCSC and ISO-aligned requirements before onboarding. Avoid costly compliance failures, penalties and reputational damage from weak third-party controls.

Early Risk Identification

Identify critical vulnerabilities such as weak access controls, missing incident response or hidden sub-processors. Address risks before they escalate into data breaches or operational disruption.

Actionable Remediation Roadmap

Receive clear, prioritised steps to fix identified gaps. We can  guide both you and your vendors towards measurable security improvements and reassessment readiness.

Stronger Supply Chain Security

Build a resilient, secure third-party ecosystem by enforcing consistent security standards. Reduce exposure to supply chain attacks, one of today’s fastest-growing cyber threats.

Our Specialised Approach to Third Party Risk Management

  • 1. Vendor Security Questionnaire Review

    We begin with a deep-dive analysis of vendor responses to a structured Third Party Security Questionnaire.

    - No assumptions, only evidence-based evaluation

    - Gaps identified where responses are missing, vague, or inconsistent

    - Supporting documents (e.g., policies, DPAs) are critically reviewed

  • 2. Multi-Domain Security Assessment

    We assess vendors across all critical risk domains, including:

    - Information Security Governance

    - Data Protection & Privacy Compliance

    - Access Control & Identity Management

    - Incident Response & Breach Handling

    - Supply Chain & Sub-processor Risk

    - Data Retention & Secure Disposal

    - Staff Security Awareness & Training

    - Business Continuity & Resilience

    - Network & Endpoint Security

  • 3. Risk-Based Evaluation Frameworkx

    Each response is evaluated against real-world impact to confidentiality, integrity, and availability of data.

    We apply a structured risk rating model based on the following risk levels:

    - Critical: Immediate risk of breach, regulatory failure, or data loss

    - High: Serious control gap requiring remediation before approval

    - Medium: Notable weakness requiring time-bound action

    - Low: Minor gap or best practice improvement

    This enables clear prioritisation and executive-level decision making

  • 4. Detailed Risk Matrix & Findings

    We produce a comprehensive findings matrix, mapping:

    - Vendor responses

    - Identified risks

    - Threat severity

    - CM-Alliance expert commentary

    Example real-world gaps identified in assessments include:

    - Lack of ISO 27001 certification or control framework

    - Non-compliant Data Processing Agreements (GDPR Article 28)

    - Undisclosed sub-processors (supply chain blind spots)

    - Absence of incident response capability

    - Weak access controls (no MFA, no RBAC)

    - Undefined data retention policies

    - Inadequate staff security training

    - Missing business continuity planning

    These are not theoretical risks. They are direct causes of data breaches and regulatory penalties.

  • 5. Clear Approval Verdict

    Unlike generic assessments, CM-Alliance provides a definitive, decision-ready outcome:

    - Approve

    - Approve with Conditions

    - Do Not Approve

    This clarity eliminates ambiguity for CISOs, risk teams, and procurement leaders.

  • 6. Actionable Remediation Roadmap

    We don’t just highlight problems. We tell you exactly what to do next.

    Our recommendations include:


    - Achieving recognised certifications (ISO 27001 / Cyber Essentials Plus)

    - Completing compliant Data Processing Agreements

    - Implementing documented incident response plans

    - Enforcing multi-factor authentication and access controls

    - Establishing data retention schedules

    - Strengthening staff security awareness programmes

    - Formalising business continuity and disaster recovery

     

    All actions are practical, prioritised, and aligned to regulatory expectations

Our methodology is structured, evidence-based and risk-driven, ensuring every decision is backed by clear analysis.

TPRA 4

What is a Third Party Risk Assessment?

A Third Party Risk Assessment evaluates the security posture, data protection practices, and operational resilience of a vendor before (or during) engagement.

CM-Alliance’s assessments are grounded in:

  • ISO/IEC 27001:2022

  • UK GDPR & Data Protection Act

  • ICO Accountability Framework

  • NCSC Cyber Essentials

We analyse whether a vendor can securely handle your data, meet regulatory obligations and/or respond effectively to cyber incidents.

Why Third Party Risk Assessments Matter

Modern cyber attacks increasingly exploit third-party weaknesses, including:

  • SaaS integrations

  • Marketing platforms

  • Cloud service providers

  • Outsourced IT and support vendors

Without structured assessment, your organisation is at risk for:

  • Data breaches through vendors

  • Non-compliance with GDPR and other regulations resulting in regulatory fines and penalties

  • Supply chain attacks

  • Operational disruption

  • Reputational damage

Client Testimonials

We have assisted numerous organisations including FIFA, NHS, Capita, BNP Paribas, Formula One Racing, British Medical Journal, and many more with assessments and audits. Here's some feedback from just a few of them.

Mudassar Ulhaq

Mudassar Ulhaq - Chief Information Officer -Waverton Investment Management

"I would recommend Cyber Management Alliance’s tabletop workshops to anyone genuinely interested in being on top of their cyber incident response strategies. The format and style of conducting the entire workshop is what I found a lot of value in. Most importantly, the scenarios on which the workshop was based were relevant to the business, making the exercise a great investment of time and resources."

Aaron-Twonsend

Aaron Townsend - Service Delivery Manager - British Medical Journal

"In order for BMJ to the right way forward we looked for a VCISO to advise us on the right way to do things and give us expertise. We went to Cyber Management Alliance and it's been about a year now and we ran workshops, looked at our response to incidents, created the incident response plan and we are in a position now where we understand our way forward. Our VCISO keeps us on our toes and overall it's been a very effective way of delivering expertise into the organisation that we wouldn't have normally had."

Neil Mallon

Neil Mallon - Strategic Technology Leader - Aster Housing

"The Cyber Crisis Tabletop Exercise and corresponding audit conducted by Cyber Management Alliance Ltd was expertly delivered and has given us insights to reinforce our cyber strategy by continuing to help build the picture of where we were, where we are now, and our next focussed steps. We will be engaging CM-Alliance on an annual basis."
