Theos built the engagement around the threat actors targeting our sector in Hong Kong. The findings were structured for HKMA submission and the gaps have since been closed.
Vulnerability Management: Continuous visibility, risk-based prioritisation, and tracked remediation.
Continuous scanning. Risk-based prioritisation. Remediation tracked and validated through to closure.
OVERVIEW
What is vulnerability management?
Vulnerability management is a continuous security programme that identifies, prioritises, and tracks the remediation of weaknesses across your environment. The distinction from a one-off scan is operational: it keeps pace with your environment as it changes and with the threat landscape as it evolves.
New vulnerabilities are disclosed every day across the threat landscape. Environments change with every deployment, configuration update, and new assets added to your network. A point-in-time scan becomes outdated the moment it is complete. Vulnerability management replaces that snapshot with a continuously updated, risk-prioritised view of your exposure.
What Vulnerability Management Includes:
-
Continuous scanning across your full asset inventory
-
Risk-based prioritisation: Severity, exploitability, asset criticality, and business impact weighted together
-
Remediation tracking: Progress monitored and validated through to closure
-
Integration with your existing patch management processes
-
Steering Committee (SteerCo) reporting: Leadership visibility into remaining exposure and remediation momentum
-
Regulatory alignment: Findings documented to the standard required for regulatory review
Business Outcome:
Your organisation always has a current and accurate view of its exposure. Remediation effort is focused where risk is highest. Regulators and insurers see a structured programme with documented evidence of continuous improvement, not a point-in-time report filed once a year.
THE PROBLEM
A scan tells you where you stood. A programme tells you where you stand.
Most organisations run periodic vulnerability scans and receive a list of findings. That list is accurate for the moment it was generated. By the time remediation begins, the environment has changed, new vulnerabilities have been disclosed, and the environment has moved on.
Without continuous scanning, risk-based prioritisation, and remediation tracking, vulnerability management becomes a compliance exercise: a report filed, a box ticked, and an exposure profile that goes stale between scan cycles. Vulnerability management keeps your exposure view as current as theirs.
What a continuous programme addresses that point-in-time scanning cannot:
Vulnerabilities disclosed between scan cycles, reflected as they emerge
New assets added to the environment, included automatically
Configuration changes that alter exposure, captured in each scan cycle
Remediation tracked and validated through to confirmed closure
Asset context: exposure weighted against criticality, not just CVSS score
THEOS APPROACH
Continuous visibility. Risk-based priority. Remediation that closes.
Theos delivers risk-based vulnerability management as a programme, not a product. Scanning is continuous. Prioritisation is risk-based. Remediation is tracked and validated. Your leadership team has a live view of exposure and momentum at all times.
Continuous Scanning
Theos runs recurring scanning across your environment using CrowdStrike Exposure Management as the primary platform, with support for Qualys, Tenable, and Microsoft Defender where clients have existing tools in place. Coverage spans internal and external systems, endpoints, servers, network devices, and cloud resources.
Risk-Based Prioritisation
Not all vulnerabilities carry equal risk. Theos prioritises findings by weighing severity scores against exploitability, asset criticality, exposure, and potential business impact. The same vulnerability carries very different risk depending on whether the affected asset is internet-facing, supports a critical business function, or processes regulated data. Your team has a clear view of where to act first, and why.
Remediation Tracking and Validation
Theos tracks remediation progress from identification through to closure. Fixes are validated before findings are closed. Where your team needs technical guidance on specific findings, Theos provides it. Remediation SLAs are agreed at the outset, aligned to severity levels and your organisation’s risk appetite.
Patch Management Alignment
Vulnerability findings are mapped to your existing patch management processes, with remediation priorities aligned to scheduled patch windows. For critical vulnerabilities requiring immediate action, Theos highlights and escalates these outside the standard cycle ensuring urgent risks are escalated outside the standard patch cycle.
SteerCo Reporting
Leadership visibility is built into the programme from the start. Theos provides structured reporting at agreed intervals, covering severity ratings, asset context, remediation status, and remaining exposure. SteerCo sessions give leadership a clear view of programme momentum and where attention is needed.

HOW IT WORKS
How Theos Vulnerability Management works.
1
Asset Discovery and Baseline
Theos establishes a full inventory of your environment and runs an initial baseline scan. Critical assets are identified and prioritised. Existing tooling and patch management processes are reviewed to ensure the programme integrates with what you already have in place.
2
Continuous Scanning
Recurring scans run across your environment on an agreed cadence. New assets are automatically included. Configuration changes and newly disclosed vulnerabilities are reflected in each scan cycle, keeping your exposure view current.
3
Risk-Based Prioritisation
Every finding is assessed against severity, exploitability, asset criticality, and business impact. Findings are classified by severity: critical, high, medium, and low. Your team receives a prioritised remediation list with the context needed to act, calibrated to your environment and risk profile, not sorted by CVSS score alone.
4
Remediation Tracking
Theos tracks remediation progress against agreed SLAs. Critical and high findings are escalated on priority. Progress is reviewed at SteerCo sessions. Technical guidance is provided where your team needs support on specific findings.
5
Validation and Closure
Fixes are validated before findings are closed. Where a patch has been applied or a configuration corrected, Theos confirms the vulnerability has been successfully remediated before removing it from the active findings list.
6
Reporting and Review
Structured reports are delivered at agreed intervals covering the full findings landscape, remediation progress, and remaining exposure. Executive summaries are produced for board and leadership review. Findings documentation is maintained in a format suitable for regulatory submission.

“
The engagement identified gaps our existing programme had not surfaced. The findings went directly into our regulatory submission and the gaps have since been remediated.
“
Theos engaged credibly at board level and at SOC level in the same programme. The ability to do both simultaneously, and produce documentation that holds up to BNM examination, is what made the difference.

USE CASES
Who Theos Vulnerability Management is built for.
Regulated enterprises with continuous compliance obligations
MAS TRM, BNM RMiT, HKMA iCAST, and BSP-regulated frameworks in the Philippines all require ongoing security controls with documented evidence. Vulnerability management provides the continuous programme and the audit trail that point-in-time assessments cannot.
Organisations with growing or changing environments
Every new deployment, configuration change, or asset added to your network is a potential change to your exposure profile. Continuous vulnerability management keeps your view current as your environment evolves, without requiring a new engagement to be scoped each time.
Security teams that need to demonstrate programme maturity
Insurers, board members, and regulators increasingly ask not just whether scanning is in place, but whether findings are being prioritised and remediated. Theos vulnerability management provides the structured programme, the tracked SLAs, and the documented evidence that demonstrates security maturity in practice.
Organisations with limited internal security capacity
Vulnerability management requires consistent attention: scanning, prioritisation, tracking, and validation. For organisations without the internal capacity to run that process continuously, Theos manages the programme end to end, with your team involved at the level that suits your resources.
Teams that need to connect vulnerability data to their broader security programme
Vulnerability findings that sit in isolation from your MDR detection programme and your pen test scope are a missed opportunity. Theos connects vulnerability management findings directly into detection tuning and offensive testing priorities, so your security programme compounds rather than runs in parallel.
WHEN DO YOU NEED VULNERABILITY MANAGEMENT
When does your organisation need vulnerability management?
Vulnerability management delivers the most value as a continuous programme aligned to your risk profile and regulatory obligations. Most regulatory frameworks governing APAC enterprises carry explicit vulnerability management requirements. The question is whether your programme satisfies them continuously or only at audit time.
Your regulatory framework requires it
In Singapore, MAS TRM requires vulnerability assessment as part of the technology risk management framework. In Hong Kong, HKMA iCAST and HKMA C-RAF require regular vulnerability assessments for authorised institutions. In Malaysia, BNM RMiT requires vulnerability management as a continuous security control. In the Philippines, BSP Circular 982 requires periodic vulnerability assessments for BSP-regulated entities.
After a significant infrastructure change
Every cloud migration, new deployment, and environment consolidation changes your attack surface. Vulnerability management initiated after significant change ensures new exposure is identified and addressed before it is exploited.
Before or after a VAPT engagement
Vulnerability management findings sharpen VAPT scope. Testers know where to look before they start. After a VAPT engagement, vulnerability management tracks remediation of findings through to confirmed closure, replacing assumption with evidence.
When preparing for regulatory review or cyber insurance renewal
Regulators and insurers expect a structured, continuous programme with tracked SLAs and documented remediation evidence. Theos provides exactly that.
WHY THEOS
Why Theos Vulnerability Management.
Closure you can verify, evidence you can present
Theos tracks every finding from identification through to validated closure. Theos confirms every fix before closing a finding.
Tools surface findings. Practitioners determine what they mean
Automated vulnerability scanning tools identify findings at scale. What they produce requires expert interpretation. Theos provides that context. Every finding is assessed by a practitioner who understands your environment, your regulatory obligations, and your threat exposure. A critical CVSS score on an asset with no external access carries a different risk than the same score on an internet-facing system processing regulated customer data. That contextual judgement is what the programme delivers. The output is a prioritised remediation list your team can act on immediately.
Remediate, mitigate, or accept
Vulnerabilities carry different levels of urgency and require different responses. Theos applies a three-way decision framework to every finding: remediation where the vulnerability can be fully resolved, mitigation where a compensating control reduces the risk while a fix is developed or scheduled, and accepted residual risk where the exposure is low enough that the organisation formally accepts it. For regulated enterprises, that acceptance decision is documented and tracked. Regulators expect evidence of a risk-based decision. Theos provides that documentation as a standard programme output.
Risk-based prioritisation that reflects your environment
Context determines risk. Every finding is prioritised against your specific asset criticality, business context, and regulatory exposure. Your team knows what to fix first and why. Context is built into every prioritisation decision.
Connected to your full security programme
Vulnerability management findings feed directly into MDR detection tuning and VAPT scope prioritisation. Clients who work with Theos across multiple service lines benefit from a security programme that compounds: a vulnerability identified in the management programme informs the next VAPT scope, and a detection gap found in MDR shapes the next vulnerability management priority.
Practitioners who understand the regulatory environment
Theos delivers vulnerability management services structured to meet the regulatory requirements of each market, delivering cybersecurity services across Singapore, Hong Kong, Malaysia, and the Philippines. Findings are documented and reported to the standard regulators in each of our markets expect. Our practitioners understand MAS TRM in Singapore, HKMA iCAST in Hong Kong, BNM RMiT in Malaysia, and the frameworks governing BSP-regulated clients in the Philippines. That knowledge is built into how we design programmes and what we prioritise. The same programme that improves your security posture produces the evidence your regulator expects.

FAQ
Frequently Asked Questions
The questions regulated enterprises ask most often before commissioning a vulnerability management programme.
What is the difference between vulnerability management and a one-off scan?
A one-off scan tells you where you stand today. Vulnerability management tells you where you stand continuously.
New vulnerabilities are disclosed daily. Environments change with every deployment, configuration update, and new asset added to your network. A point-in-time scan becomes outdated the moment it is complete. Vulnerability management combines regular scanning, risk-based prioritisation, and remediation tracking so your organisation always has a current and accurate view of its exposure.

What tools do you use for vulnerability management?
Theos primarily uses CrowdStrike Exposure Management to deliver continuous visibility across on-premise, cloud, and hybrid environments, with real-time insight into vulnerabilities, asset exposure, and risk posture. We also support and integrate with Qualys, Tenable, and Microsoft Defender. For clients with existing tools in place, Theos assesses compatibility and integrates with your current ecosystem, integrating with your existing ecosystem.
Findings are analysed and prioritised based on risk so your team always knows where exposure is highest and where to act first.

How do you prioritise which vulnerabilities to remediate first?
Theos prioritises vulnerabilities using a risk-based approach that weighs severity scores alongside broader contextual factors. We consider vulnerability severity, exploitability, asset criticality, exposure, and potential business impact to determine where remediation efforts should be focused first.
Context plays a key role. The same vulnerability may carry very different risk depending on whether the affected asset is internet-facing, supports a critical business function, or processes sensitive data.
Prioritisation is aligned to your environment and risk profile, ensuring your team has a clear, actionable view of what to fix first, and why.

How does Theos support vulnerability remediation?
Theos supports the full remediation lifecycle, from identification through to validation and closure. We track remediation progress, validate that fixes have been correctly implemented, and confirm vulnerabilities are resolved before closing them out.
Where your team needs support, we provide technical guidance and context on specific findings, supporting efficient and validated remediation.

How do you track and report vulnerability remediation progress?
Theos provides structured vulnerability reporting covering severity ratings, asset context, and remediation status across your environment. Findings are classified by severity: critical, high, medium, and low, each documented with the context your team needs to prioritise and act.
Theos and your team agree remediation SLAs at the outset, aligned to severity levels and your organisation’s risk appetite. Progress is tracked continuously throughout the programme and reviewed at SteerCo sessions, giving leadership a clear view of remaining exposure and remediation momentum.

How does vulnerability management integrate with patch management?
Theos aligns vulnerability management with your existing patch management processes to ensure remediation efforts are coordinated and risk-prioritised. Vulnerability findings are mapped to patching cycles, allowing remediation priorities to align with scheduled patch windows and giving your team a clear view of what needs to be addressed and when. For critical vulnerabilities requiring immediate action, Theos highlights and escalates these outside the standard patch cycle, ensuring urgent risks are escalated outside the standard patch cycle.
How does vulnerability management help meet regulatory requirements?
Regular scanning, risk-based prioritisation, and documented remediation tracking are components regulators and auditors expect when assessing a cybersecurity programme. Theos structures engagements to align with the frameworks governing your organisation, with findings and remediation progress documented in a format that supports regulatory review and demonstrates security maturity with evidence.
Is vulnerability management a one-time service or an ongoing process?
Vulnerability management is an ongoing process. New vulnerabilities are disclosed daily, environments change continuously, and a point-in-time assessment is outdated the moment it is complete.
Theos delivers vulnerability management as a continuous programme, with recurring scanning, risk-based prioritisation, and remediation tracking built in. Where a targeted assessment is needed for a specific initiative or review, Theos can scope that separately. For organisations that want a current and accurate view of their exposure at all times, the ongoing programme is the right answer.

What types of assets are covered under vulnerability management?
Vulnerability management covers a wide range of assets across your environment, including internal and external systems, servers, endpoints, network devices, and cloud resources. Scope is defined based on your organisation’s infrastructure, risk exposure, and business requirements, with priority given to the assets that carry the highest risk to your organisation.
