RiskXchange Scoring System: A Comprehensive Guide

Executive Summary

The RiskXchange Combined Score represents a sophisticated approach to third-party risk assessment, providing organisations with a unified framework to evaluate external cybersecurity threats and internal governance capabilities. This dual-component system enables comprehensive risk visibility while maintaining the flexibility to adapt to specific organisational needs and regulatory requirements.

System Overview

What is the RiskXchange Combined Score?

The RiskXchange Combined Score is a comprehensive third-party risk rating system that evaluates an organisation's overall risk posture through two integrated assessment methodologies. This unified approach provides stakeholders with a single, actionable risk metric ranging from 0-900 points that encompasses both technical security vulnerabilities and governance compliance factors.

Organisations should aim to maintain a score of 800+ to demonstrate strong risk management and security posture.

Core Design Philosophy

The system is built on the principle that effective risk management requires both external threat assessment and internal control evaluation. By combining these perspectives, organisations gain a holistic view of their risk landscape that supports informed decision-making across security, compliance, and business operations.

System Architecture

Two-Component Framework

The RiskXchange Combined Score integrates two distinct but complementary assessment components:

1. RX Score (External Cybersecurity Posture Risk)

Purpose: Evaluates publicly accessible digital footprint vulnerabilities
Methodology: Continuous, non-intrusive automated security assessments
Scope: External-facing systems and infrastructure
Update Frequency: Continuously updated every 24 hours or weekly, depending on customer requirements

2. Assessment Score (Internal Security & Compliance)

Purpose: Evaluates internal governance, compliance, and regulatory alignment
Methodology: Structured assessments including questionnaires and policy evaluations
Scope: Internal controls, policies, and compliance frameworks
Update Frequency: Continuously updated via the RiskXchange assessment exchange as vendors make updates to shared assessments

RX Score: External Cybersecurity Assessment

Assessment Methodology

The RX Score employs automated, continuous monitoring of an organisation's external digital presence to identify security vulnerabilities across multiple attack vectors. This non-intrusive approach ensures up-to-date risk visibility without impacting operational systems, with scores updated every 24 hours or weekly depending on customer requirements.

Security Domain Categories

The RX Score evaluates eight critical security domains, each weighted according to its impact on overall security posture:

High-Impact Categories (300+ points)

Cyber Attacks (300 points - 33%)

Detects publicly disclosed data breaches and ransomware incidents
Monitors threat intelligence feeds for organisation-specific mentions
Assesses historical breach patterns and recovery effectiveness
Evaluates incident response transparency and communication

Core Security Categories (190 points each - 21%)

Application Security (190 points - 21%)

Identifies common web application vulnerabilities (OWASP Top 10)
Assesses API security and exposure
Evaluates authentication and authorisation mechanisms
Tests for injection attacks and cross-site scripting vulnerabilities

Network Security (190 points - 21%)

Identifies insecure network configurations
Assesses firewall effectiveness and rule configurations
Evaluates network segmentation and access controls
Tests for open ports and unnecessary services

Encryption (190 points - 21%)

Evaluates SSL/TLS implementation and configuration
Assesses certificate management and expiration monitoring
Tests encryption strength and cipher suite selection
Identifies weak encryption protocols and deprecated algorithms

Supporting Security Categories

Mail/DNS Security (180 points - 20%)

Evaluates email security configurations (SPF, DKIM, DMARC)
Assesses DNS security and configuration integrity
Tests for DNS hijacking and cache poisoning vulnerabilities
Monitors email reputation and spam filtering effectiveness

Database Servers (90 points - 10%)

Identifies exposed or misconfigured database servers
Assesses database access controls and authentication
Evaluates data exposure and unauthorised access risks
Tests for database injection vulnerabilities

Malware (90 points - 10%)

Detects suspicious network activity and malware presence
Monitors malware distribution and command-and-control communication
Assesses endpoint protection effectiveness
Evaluates threat response and remediation capabilities

Business Reputation (30 points - 3%)

Assesses domain reputation across security services
Monitors blacklist status and reputation scores
Evaluates brand protection and domain security
Tracks reputation recovery and maintenance efforts

Scoring Methodology

The RX Score utilises a weighted scoring system with a maximum of 900 points distributed across the eight security domains. The Combined Score, incorporating both RX Score and Assessment Score components, ranges from 0-900 points, with organisations ideally aiming to maintain a score of 800+ to demonstrate strong risk management and security posture. Each domain's contribution reflects its relative importance in the overall security risk assessment:

Critical Impact: Cyber Attacks (33%) - Highest weight due to direct business impact
Foundation Security: Application, Network, Encryption (21% each) - Core security components
Infrastructure Support: Mail/DNS (20%) - Communication and infrastructure security
Specialised Areas: Database, Malware (10% each) - Focused threat vectors
Reputation Monitoring: Business Reputation (3%) - Supporting intelligence

Assessment Score: Internal Security & Compliance

Assessment Framework

The Assessment Score evaluates an organisation's internal security governance, compliance measures, and regulatory alignment through structured assessments and policy evaluations. This component ensures that external security measures are supported by robust internal controls and governance frameworks.

The Assessment Score is continuously updated through the RiskXchange assessment exchange system. When vendors make updates to their shared assessments—such as uploading new certificates, providing updated responses, or making compliance changes—these updates are automatically reflected in their Assessment Score. All companies who have previously requested these assessments are automatically notified of any changes, ensuring that stakeholders remain informed of modifications to vendors' compliance or risk status in real-time.
