Continuous Threat Exposure Management (CTEM)
A Gartner-defined five-stage programme that continuously scopes, discovers, prioritises, validates, and mobilises remediation of your organisation's exploitable exposure.
The Case for Continuous Threat Exposure Management
Vulnerability management programmes that prioritise by CVSS score alone remediate the wrong vulnerabilities while critical exploitable exposure accumulates unaddressed.
Of published CVEs are ever exploited in the wild — CVSS-only prioritisation wastes 95% of remediation capacity
[CISA KEV and EPSS Research 2023]
Of breaches in 2023 involved a vulnerability for which a patch was already available

CTEM Programme vs. Traditional Vulnerability Management
Traditional vulnerability management programmes generate CVSS-scored findings and dispatch patch tickets. The problem is structural: CVSS measures theoretical severity, not exploitability in your specific environment. Organisations with 50,000+ open findings cannot remediate everything — but traditional programmes provide no reliable mechanism to identify the 500 that an adversary would actually use to breach their environment. The result is a false sense of security while real exposure accumulates.
CTEM, defined by Gartner as a five-stage continuous programme, replaces theoretical severity with actual exploitability. Vyomerc's CTEM practice combines EPSS-based prioritisation, CISA KEV alignment, attack path analysis, and Breach and Attack Simulation to identify which vulnerabilities sit on a path to a crown-jewel asset — and mobilises remediation resources against those findings first, with validated SLAs and board-level exposure trend reporting.
Vyomerc CTEM
CVSS-Based Vulnerability Management
Prioritisation model
EPSS probability of exploitation + CISA KEV active exploitation + attack path to crown jewels
CVSS score alone — theoretically high severity without context of exploitability
Validation
BAS validates whether compensating controls prevent exploitation before closing findings
Findings closed on patch installation — no validation of control effectiveness
Executive reporting
Exposure trend scoring against industry benchmarks with financial risk quantification
Vulnerability count metrics with no business context
Remediation focus
Top 23 critical exploitable findings on attack paths to crown-jewel assets
Patch backlog prioritised by CVSS 9.0+ — thousands of findings, no clear priority
Operational Workflow
How the Engagement Executes.
[PHASE_01]
Scoping & Asset Discovery
Definition of CTEM programme scope covering all internal, external, and cloud attack surface — with full asset inventory and crown-jewel asset identification.
[PHASE_02]
Continuous Exposure Discovery
Ongoing vulnerability scanning, EASM discovery, and attack path analysis to maintain a current and complete view of exploitable exposure across the scoped environment.
[PHASE_03]
Risk-Based Prioritisation
EPSS + CISA KEV + attack path scoring to identify the subset of findings that represent real breach risk — collapsing the remediation backlog to actionable priorities.
[PHASE_04]
Validation & Mobilisation
BAS validation of compensating control effectiveness, remediation SLA tracking, and monthly executive exposure trend reports with financial risk quantification.

Technical Specification & Deliverables.
EPSS + KEV Prioritisation
Exploit Prediction Scoring System combined with CISA Known Exploited Vulnerabilities catalogue identifies the 5% of findings that represent real breach risk from the 95% that do not.
Attack Path Analysis
Graph-based attack path analysis maps the routes from external exposure to crown-jewel assets, prioritising vulnerabilities that sit on viable attacker paths over theoretically severe but isolated findings.
BAS Validation
Breach and Attack Simulation validates whether compensating controls successfully prevent exploitation of prioritised findings — ensuring remediation closure means actual risk reduction.
CTEM Engagement
Fix the 5% that matter, not the 95% that don't.
We conduct a CTEM scoping assessment identifying your top exploitable attack paths and mapping current prioritisation gaps before designing your programme.
