Three weeks reading service descriptions and contract terms. What separates these seven, and which fits which kind of team.

An intrusion at 2 a.m. in Singapore or Sydney needs someone awake and authorised to act. Every managed detection and response provider makes that pitch in roughly the same words.

What I wanted to know was narrower. Who is permitted to touch my systems overnight, what will they do without asking me first and can I see it written down before I sign. So I read the service descriptions and admin documentation instead of the marketing pages. The differences turned out to be large, and most are invisible on a comparison chart.

How I evaluated these

Four things per provider: published response authority, what the service does without customer approval, coverage across endpoint, identity, network and cloud, plus whether any containment commitment appears in the service description rather than the brochure. Everything below comes from vendor documentation, not review aggregators.

They are grouped by the kind of buyer they suit rather than ranked, because the honest answer to “which is best” depends on how much control you are willing to hand over.

At a glance

1. ESET

Best for businesses that want a defined upgrade path from SMB to enterprise coverage.

ESET sells the service in two subscriptions. ESET PROTECT MDR targets small and mid-sized businesses. ESET PROTECT MDR Ultimate targets enterprises and adds customised and retrospective threat hunting, digital forensic incident response assistance and a dedicated incident response lead.

The detail I found most useful is the published response benchmark: a six-minute mean time to respond, measured from the identification of an incident to the first action taken. At the enterprise tier, each engagement starts with an assessment of your environment, infrastructure and needs, which is used to build an individual security profile.

Both tiers run 24/7 and pair AI-driven detection with human analyst investigation. The service was named a Market Leader in MDR in the KuppingerCole Leadership Compass 2026.

2. Sophos MDR

Best for teams that want response authority written down and adjustable.

Sophos is the clearest of the seven on this point. You pick one of three threat response modes in the console. Notify Only means the team investigates and tells you, nothing more. Collaborate means no response action happens without your written consent. Authorise means Sophos acts and informs you afterward.

A checkbox under Collaborate lets the team escalate to Authorise behaviour if they cannot reach your contacts, which is the setting that matters overnight in a small team. The service description commits to a Time to Respond within 60 minutes for 90% of priority investigations, measured monthly. Watch the tier split: Essentials covers containment and escalation with your team doing full neutralisation, while Complete adds full-scale incident response and cleanup.

3. Huntress Managed EDR

Best for lean IT teams and MSPs with no dedicated security staff.

Huntress runs a 24/7 human-led, AI-assisted SOC across Managed EDR, Managed ITDR and Managed SIEM. What suits small teams is that managed host isolation is on by default. An analyst confirms the threat, sends the incident report and the endpoint is isolated as the report goes out.

Detection leans on persistent foothold hunting, behavioural analysis and ransomware canaries rather than signatures alone. On Windows it works alongside Microsoft Defender and manages the antivirus layer at no additional cost. The trade-off is scope: this is endpoint and identity depth, not a broad multi-signal platform.

4. eSentire MDR

Best for buyers who want a containment commitment in the contract, not a marketing figure.

eSentire publishes a mean time to contain of under 15 minutes and sells it as a contractual commitment rather than a historical average. That is unusual, because most providers here do not publish standard commercial SLA terms at all.

The Atlas XDR platform ingests endpoint, network, log, cloud and identity signals across more than 300 technology integrations, and the company reports serving over 2,000 organisations across 80 or more countries. Packaging runs as Atlas Essentials, Atlas Advanced and Atlas Complete.

Ask two things before quoting that SLA. What action the clock measures, since detection, notification and containment are three different events. And whether it holds when you use a third-party EDR agent.

5. Arctic Wolf

Best for mid-market teams that want a named group of people rather than a ticket queue.

Arctic Wolf assigns each customer a Concierge Security Team, and that is genuinely the product. The MDR licence includes the Arctic Wolf Agent and Active Response, with telemetry pulled from internal and external networks, endpoints and cloud environments.

The Aurora platform uses an open XDR architecture designed to sit on top of your existing tools rather than replace them, with more than 200 integrations. For a business carrying a mixed stack across several APAC offices, that matters more than raw detection quality. Standard commercial SLA terms are not broadly published, so treat response timing as something to negotiate.

6. CrowdStrike Falcon Complete

Best for enterprises that want the widest telemetry and provider-owned remediation.

Falcon Complete covers endpoints, identity, cloud workloads and third-party data ingested through Falcon Next-Gen SIEM. The model is full-cycle: the provider detects, investigates, remediates and restores rather than handing you a task list.

CrowdStrike backs it with warranty coverage of up to USD 2 million and was named a Leader in the IDC MarketScape Worldwide MDR/MXDR for the Enterprise 2026 Vendor Assessment.

This is the heaviest option here in capability and commitment. If your environment is not already Falcon-centric, price the platform underneath the service first.

7. Acronis MDR

Best for MSPs and businesses that want detection and recovery in one console.

Acronis is the outlier, and recovery is why it earns a place. The SOC delivers 24/7/365 monitoring, investigation and response, and because it sits inside Acronis Cyber Protect Cloud the remediation options include rolling an attack back from backup.

For a business running one console for backup, endpoint management and security, that consolidation is a real saving. One requirement to know: MDR runs on top of Acronis EDR or Acronis XDR, so the base product has to be in place first.

The APAC layer most comparisons skip

Two regional obligations shape this decision before features do, and they move faster than the APAC security trends most vendor comparisons are built around.

Singapore licenses cybersecurity service providers under Part 5 of the Cybersecurity Act. Since April 2022 the Cybersecurity Services Regulation Office has licensed penetration testing and managed SOC monitoring services. Verify the licence before you shortlist.

Australia’s notifiable data breach scheme requires covered organisations to assess suspected eligible breaches and notify where required. MDR supports that with incident timelines and containment records, but the assessment and the notification decision stay with you. Check data residency too, since where telemetry is stored and who can reach it differs by provider and sometimes by region.

What I would ask on every call

• Which response actions happen without contacting us, and can that differ by asset group?
• Is your containment figure contractual or historical, and what event starts the clock?
• Which of our tools do you ingest, and which of those support response rather than monitoring only?
• Do you call after hours, or only email? Who is the backup on a public holiday?
• Where is our telemetry stored, for how long and who can access it?
• What forensic and recovery work is included, what is capped and what bills separately?

Then ask to see the contract clause defining what the provider may and may not do during an incident, and walk an overnight scenario through it.

Budgeting and the first 90 days

Pricing runs per user, per server or per endpoint, with add-ons for data collection, extended retention and forensic hours. Several providers here also require a base platform subscription underneath the service, so compare quotes against one shared scope. Use the first 90 days to confirm coverage, test escalation contacts and track containment times. Fewer alerts alone does not prove the service works.

Frequently asked questions

Which MDR providers publish a contractual containment or response commitment? eSentire publishes a 15-minute mean time to contain as a contractual commitment. Sophos commits to a Time to Respond within 60 minutes for 90% of priority investigations, measured monthly. Arctic Wolf, CrowdStrike, Huntress and Acronis do not broadly publish standard commercial SLA terms.

Which MDR service lets us control what the provider does without asking us? Sophos is the most explicit, with three selectable threat response modes covering notification only, consent-based action and pre-authorised action. Most others set this during onboarding rather than exposing it as a setting.

What is the best MDR option for a small business with no security staff? Huntress Managed EDR suits this profile, since managed host isolation is on by default and the SOC investigates before anything reaches you. ESET PROTECT MDR works for teams wanting a defined path to enterprise-tier coverage. Acronis MDR fits if you would rather run security and backup from one console.

Which MDR providers work with our existing security tools? Arctic Wolf’s Aurora platform uses an open XDR architecture with more than 200 integrations. eSentire’s Atlas platform carries more than 300. CrowdStrike ingests third-party data through Falcon Next-Gen SIEM. Confirm which integrations support response actions and not just monitoring.

Do we need a CSA licensed provider in Singapore? If you are procuring managed security operations centre monitoring services in Singapore, the provider must hold the relevant licence issued through the Cybersecurity Services Regulation Office. Ask for the licence number and validity dates.

Is MDR the same as an MSSP? Not usually. MDR generally implies analyst investigation and hands-on response, while traditional MSSP arrangements lean toward managing tools and escalating alerts. Read the contractual response obligations rather than the label.

Does MDR cover our compliance obligations? No. It produces evidence that supports them. Incident timelines and containment records help your auditors, but breach assessment, notification decisions and legal accountability remain yours.

Which MDR provider offers recovery as part of remediation? Acronis MDR, because the service runs inside a platform that also holds your backups. Most others stop at containment and cleanup and expect recovery to run through your own backup tooling.

Manage it right

After three weeks of reading contracts, the conclusion I keep returning to is that the best MDR service is not the one with the most sophisticated detection. It is the one whose response authority matches how much control your team is willing to give up at 2 a.m. A provider that acts without asking is a gift to a two-person IT team and a liability to a regulated business with change-control requirements. Work out which one you are first, and the shortlist writes itself.
