Managed Detection and Response (MDR)
Noise is Risk. Precision is Protection
Overview
If your team is asleep, you can bet that treat actors aren’t.
Reliance Cyber’s Managed Detection and Response service blends round the clock SOC analysts and threat hunters with a growing library of powerful automations, tuned to your environment and enriched with industry-leading threat intelligence, to deliver protection in minutes.
Our strategic use of AI allows us to enrich context, cluster related activity and accelerate investigations to contain threats in real-time.
We don’t just reduce alerts; we fix the underlying vulnerabilities that put you at risk.

Cyber security outcomes we deliver
Protection in minutes, not months
Achieve baseline coverage in approximately 30 minutes so the project gap attackers can exploit is removed on day one, not next quarter.
Immediate risk reduction
Day-one rules and playbooks detect and respond to ~80% of MITRE ATT&CK TTPs, cutting incident volume and severity before it effects production systems.
Intelligence-led
decision making
Every alert carries context from over 2.4 billion threat indicators (Google, Mandiant, VirusTotal) and cross-sector insights to accelerate investigations and reduce escalations that stall action.
Response
by default
Real-time containment and responder action deliver ~3 minute Mean-Time-To-Respond to shrink dwell time and prevent revenue-impacting outages.
Complete estate visibility
Estate-wide visibility across cloud, endpoint, on-prem and IoT/OT removes blind spots, shortens investigations and produces board and audit-ready evidence.

Accelerated
onboarding
Infrastructure-as-Code allows us to deploy SIEM (dashboards, rules, integrations, forwarders and health monitoring) and SOAR (environment, playbooks and integrations) in minutes so you’re protected while we create bespoke rules and detections, tuned to your specific environment.
Automated
containment
50+ playbooks and 2200+ automated actions isolate endpoints, block malicious processes and disable compromised accounts to reduce the blast radius, while analysts complete eradication and recovery. Strategic AI correlates signals, suppresses benign patterns and summarises investigations so analysts can act quickly to protect you.
Full
transparency
You see every tool, action and data point with clear action logs and reviews you can defend when in board meetings or under audit.
Executive
reporting
Tie actions to risk reduction and program priorities with executive-ready reports you can take directly to the board.
Unified
visibility
Single pane of glass view across cloud, endpoints, on-prem and IoT/OT removes blind spots and shortens investigation time.
Community
intelligence
We share non-sensitive Indicators of Compromise across our client base, so once one customer is protected, all customers are protected. New detection rules proven in one environment are promoted and rolled out across our customer base through CI/CD, so all customers are protected automatically and without manual work.

MDR FAQs
Q: What is Managed Detection and Response (MDR)
Managed Detection and Response is a 24/7/365 service that monitors your environment, investigates alerts and contains threats so incidents don’t escalate. It combines automated playbooks with human analysts who act within agreed guardrails.
Q: How Does Managed Detection and Response Work?
Managed Detection and Response (MDR) is a cyber security service that combines advanced technology (like EDR and Machine Learning) with human expertise to provide 24/7/365 security monitoring for your organisation. The process works by first deploying agents to collect data from your network and endpoints. SOC Analysts then use this data to proactively hunt for threats, filter out false alarms, rapidly detect confirmed threats and take immediate action to contain and remediate them.
Q: What Does MDR Include?
The core components of most MDR services include: 24/7 monitoring, investigation and containment, threat intelligence enrichment, SOAR with automated playbooks, incident response and proactive threat hunting.
Q: Will MDR Work With Our Existing Tools?
Yes. We integrate with major endpoint, identity, email, cloud, network and IoT/OT platforms using open connectors and APIs. Your current stack stays productive and under your control.
Q: How Are Containment Actions Authorised?
We pre-agree guardrails and approval workflows for isolation, threat blocking and account controls. Low-risk actions are handled by automation, while higher-risk actions require analyst and business approval. Every step is logged and reversible.
Q: What Happens During a Live Incident?
We triage, execute approved playbooks and contain the incident within guardrails, notifying you based on defined criteria. An analyst leads the case, coordinates any changes with your on-call team and issues closure notes with recommended next steps.
