Managed Threat Detection and Response: Built to stay ahead of fast-moving adversaries.

THEOS Cyber delivers managed threat detection and response for regulated enterprises across APAC. Practitioners on call, 24/7. Critical alerts acknowledged within 15 minutes.

overview

What is Managed Detection and Response? 

Managed detection and response (MTDR) is a fully managed security service that monitors your environment around the clock, investigates threats with expert analysis, and takes action to contain them. Your internal team does not need to act first.

Where traditional managed security services stop at alerting, MTDR goes further. Theos analysts detect, investigate, and respond. When a threat is confirmed, containment begins. Not a ticket.

  • Continuous threat monitoring across endpoint, cloud, identity, and network
  • Expert-led investigation with full attack context
  • Confirmed threat response and containment 
  • Threat hunting to find what automated detection misses 
  • Reporting and insights that feed into your broader security programme 
  • Fewer successful breaches. Faster recovery when they happen.
  • A security posture your regulators and board can rely on.
THE CHALLENGE

The gap between alerts and outcomes is where breaches happen. 

Security is not a product you buy. It is an outcome you earn. Most organisations in APAC have some form of security monitoring in place. The problem is not a lack of tools. It is a lack of qualified practitioners to act on what those tools surface.

Traditional SOC models generate volume. Alert fatigue is real. Analysts spend cycles triaging noise rather than investigating confirmed threats. When something real arrives, the response is slow. Context is missing, escalation is manual, and the team responding does not know your environment well enough to act decisively.

The gap between detection and containment is where breaches compound. Every minute counts.

Common failure points: 

Alert Fatigue
High volume, low signal,
missed threats 
Slow Response
Manual escalation, unclear ownership
Lack of Context
Generic playbooks,
no environment-specific knowledge
Compliance-first Posture
tools deployed for audit, not outcomes
THEOS APPROACH

Detection means nothing without response. We deliver both.

Theos MTDR is built on one principle: detection without response is just monitoring. We close that gap.

Expert-Led Detection

Managed threat detection and response at Theos is practitioner-led. Our analysts monitor your environment continuously, with context about your critical assets, your industry, and the threat actors active in your region. When something triggers, they already know what matters.

Integrated Response

When a threat is confirmed, containment begins. Our response capabilities are integrated directly into the detection workflow, so the same team that identifies the threat acts on it, escalating to DFIR when the situation demands it.

Intelligence-Driven Prioritization

Alerts are weighted by impact. Theos analysts apply threat intelligence from our active incident response practice across APAC to focus resources on what demands immediate attention. The result is stronger signal and faster action, for your team and ours.

HOW IT WORKS

How Theos MTDR works.

Detect
Continuous monitoring across your environment. Alerts generated by your security stack are enriched with threat intelligence and analyst context before any action is taken. 
 Investigate 
Every alert that warrants attention is investigated by a Theos analyst. Not an automated rule. We determine what happened, what is at risk, and what needs to happen next. 
Decide
Our analysts make a qualified determination: false positive, watchlist, or active threat. You are notified with context, not noise. For critical threats, escalation is immediate.
Respond
Confirmed threats trigger containment. Theos acts within your agreed response parameters — isolating endpoints, blocking lateral movement, or escalating to full DFIR where required. Critical incidents acknowledged within 15 minutes.

What outcome accountability
looks like in practice. 

THEOS operates across Singapore, Hong Kong, Malaysia, and the Philippines, serving regulated enterprises where the cost of a breach is highest. What our clients describe is not a vendor relationship. It is a security partnership. 

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.

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 MTDR is built for.

Teams overwhelmed by alert volume

If your analysts are spending more time triaging noise than investigating real threats, Theos MTDR rebalances that equation. We handle the volume. Your team focuses on what matters.

Organisations without a 24/7 SOC

Building and sustaining a round-the-clock security operations capability is difficult to staff and slow to build. Theos MTDR gives you that capability immediately, with practitioners who already know this region.

Organisations that need faster response

If your current MTTR is measured in hours or days, a breach will compound before containment begins. Theos MTDR is built around a 15-minute critical acknowledgement SLA and integrated response that acts, not just alerts.

Regulated enterprises

Whether you are a financial institution in Singapore operating under MAS TRM, a bank in Malaysia governed by BNM RMiT, or a BSP-regulated entity in the Philippines, Theos MTDR is aligned to the compliance frameworks that govern your environment.

WHY THEOS

What separates Theos MTDR
from every other option in this market. 

Outcome-focused delivery

Every Theos MTDR client has a dedicated Customer Success Manager who owns delivery from onboarding through the life of the engagement. Commitments are tracked. Outcomes are reported. Escalations reach a decision-maker directly. Every time.

Integrated DFIR + MTDR 

When a threat escalates beyond containment, Theos does not hand you off to a third party. Our digital forensics and incident response capability is in-house. The team that detected the threat is the team that responds to the breach. There is no gap in context. There is no hand-off delay.

Intelligence that compounds 

Every incident Theos responds to feeds intelligence back into our detection programme. Clients benefit from what we have seen across the region, not just what has happened inside their own perimeter. Each engagement builds on the last.

Continuity across every engagement 

Theos clients work with the same senior practitioners across every engagement. For regulated organisations with complex, evolving threat environments, this continuity compounds over time. Global providers rotate their teams. Theos does not.

Built for this region 

Theos holds CREST accreditation, CSRO licensing in Singapore, NACSA certification in Malaysia, and DICT certification in the Philippines. Our practitioners understand MAS TRM in Singapore, HKMA iCAST, C-RAF, and GL20 in Hong Kong, and BNM RMiT and the Cyber Security Act 2024 in Malaysia. That knowledge is built into how we deliver, not bolted on at the end of an engagement.

GET PROTECTED TODAY

Security is not a product you buy. It is an outcome you earn.

Your adversaries are not waiting. Neither should you.
Every hour without expert-led monitoring and response is exposure. Theos MDR is built for regulated enterprises across APAC that measure security by what it prevents, not what it reports.

We deliver outcomes

COMMON QUESTIONS

FAQs

The questions regulated enterprises in APAC ask most often before engaging a managed detection and response provider. Answered directly.

What is the difference between MDR and MSSP?

An MSSP monitors and alerts. An MDR provider monitors, investigates, and responds. Theos MTDR does not hand you a ticket when something is detected. We act on it. The distinction matters most when a real threat arrives and minutes determine the outcome.

Do I need to replace my existing security tools?

No. Theos MTDR integrates with your existing stack, including CrowdStrike, Microsoft Defender, and Sentinel. We work with what you have and tune detection to your environment over time.

Is Theos MTDR aligned to regulatory requirements in my market?

Yes. Theos holds CREST accreditation, CSA certification in Singapore, NACSA certification in Malaysia, and DICT certification in the Philippines. Our MTDR programme is aligned to MAS TRM, BNM RMiT, HKMA iCAST, C-RAF, and GL20.

What does your MDR service actually monitor?

Endpoint activity, identity and authentication logs, cloud workloads, network telemetry, and application sources, correlated in a centralised SIEM. Theos MTDR covers the full attack chain: initial access, lateral movement, privilege escalation, data exfiltration, and ransomware pre-cursor activity.

Cloud coverage includes AWS, Azure, and GCP. We integrate with Microsoft 365, Azure AD, Entra ID, Okta, common firewall and proxy vendors, email security gateways, and most standard EDR products.

The sources in scope are agreed during onboarding and expand as your environment evolves.

What are your SLAs for threat detection and response?

Theos MTDR SLAs are severity-based. Critical: 15-minute acknowledgement, response initiated immediately. High: 30 minutes, response within 1 hour. Medium: 2 hours, response within 8 hours. Low: next business day, response within 2 business days.

What happens when a real threat is detected?

The analyst acknowledges the alert within the SLA window and validates whether it is genuine. If confirmed, pre-approved containment actions begin immediately: isolating a host, terminating a process, blocking a hash, revoking a session. Your designated security contact is notified for High and Critical incidents. A dedicated bridge is opened and maintained until the threat is contained. After resolution, a written incident report covers root cause, timeline, and detection improvement recommendations. 

If the incident goes beyond standard MDR scope, whether enterprise-wide compromise, ransomware, or regulatory exposure, our DFIR team is engaged directly. Coverage and accountability remain continuous throughout. 

 Do you provide 24/7 coverage, and from where?

Yes. Theos MTDR runs continuously, every hour of every day. We are headquartered in Singapore, with operational presence across Hong Kong, Malaysia, and the Philippines, keeping operations in the same time zones as your business.

Can MDR work alongside our in-house security team?

Yes. The model is agreed during onboarding through a RACI framework and escalation matrix. Theos handles monitoring, investigation, and pre-approved response. Your team retains authority over business-impacting decisions. Boundaries are explicit from day one.

What does reporting look like?

You have continuous access to case records, investigation notes, analyst actions, and SLA performance through our Incident Response Platform. Operational sessions cover the prior period’s incidents, detection quality, and open actions. Monthly Steering Committee sessions cover SLA performance, incident trends, detection engineering updates, and security posture. Reports include SLA adherence, true and false positive ratios, MITRE ATT&CK coverage, asset health, and remediation tracking. Custom dashboards can be built for specific requirements.

How does transitioning to Theos MDR work if we already have a provider?

Theos assumes monitoring responsibility from day one, keeping your environment protected while the new implementation is built. We assess what is deployed, what is configured correctly, and where the gaps are, then agree a remediation plan before full operations begin.

Monitoring is live immediately. Uplift follows. The primary driver of transition timeline is your internal coordination and contract timing with your existing provider. Theos handles the technical side.
