Managed Detection and Response (MDR) is a managed cybersecurity service that detects and contains active threats. MDR addresses attack techniques that bypass firewalls and antivirus software, and provides continuous monitoring and response for your business, without the cost of an internal security team.
At Microbyte, we deliver this capability as a fully managed service, combining advanced telemetry with human expertise to neutralise attacks before they disrupt your operations.
MDR operates as a remote Security Operations Centre (SOC) for your business. It employs human security analysts to monitor your network activity 24/7 and investigate suspicious behaviour that automated tools miss.
A traditional service notifies you of a problem, but an MDR service moves beyond this by actively containing the threat. If a laptop is compromised, the MDR team will isolate the device to prevent the spread of infection, removing the burden of constant vigilance from your internal team.
| Function | What Happens |
| Detection | Endpoint and identity activity is monitored continuously. |
| Investigation | Human analysts validate suspicious behaviour against known threat tactics. |
| Containment | Compromised devices are isolated from the network immediately. |
| Remediation | Malicious processes are killed, and persistence mechanisms are removed. |
| Reporting | Incident timelines and forensic evidence are delivered for compliance. |
Managing security for remote workers is a significant challenge, especially considering how ransomware attacks now combine credential theft, lateral movement, and data exfiltration. Firewalls only protect the network perimeter, but remote work removes this perimeter entirely.
Antivirus software relies on file signatures to look for known bad files, but modern attackers use “fileless” techniques. They now utilise legitimate administrative tools, like PowerShell, that antivirus software sees as benign.
In June 2023, UK haulage firm KNP Logistics declared it was going into administration, after 158 years of operating, because a ransomware attack had crippled its systems. KNP logistics had standard IT security measures in place, but the attack still prevented the movement of their trucks and goods. This incident demonstrates that standard compliance tools cannot stop active human-operated attacks.
Understanding the distinction between these services is key to making the right investment.
Think of an MSSP as a burglar alarm; it makes a loud noise when a window breaks but it relies on you to wake up and investigate.
Think of MDR as a private security detail; they watch the cameras 24/7, spot the intruder before the window breaks, and intercept the threat while you sleep.
Automated tools lack business context. Human analysts can correlate endpoint activity, identity logs, and cloud access events into a single incident timeline, providing vital context. We will handle this complexity so you can focus on your business.
When an administrator uses a network scanner to fix a printer, and a hacker uses the same scanner to find targets, an algorithm will see two identical actions. Only a human analyst is able to investigate the context of these actions to determine intent.
Attackers often use pre-installed Windows tools, a technique called “living off the land”, to launch an attack where no malicious files are downloaded and automated defenses remain silent. Human threat hunters can search for the subtle anomalies these activities create.
At Microbyte, we adopt a vendor-agnostic approach and maximise the value of the licenses you already own.
Many UK SMEs own licenses for Microsoft Defender for Business, and our MDR service integrates directly with this platform. We ingest telemetry from Defender, which avoids the cost of redundant software agents.
We monitor Microsoft Entra ID (formerly Azure AD) to detect compromised identities. We look for “impossible travel” events, such as a user logging in from London and Lagos within the same hour, and we monitor for suspicious inbox rules.
Adopting MDR helps alleviate the pressure of regulatory compliance.
UK GDPR requires the reporting of specific data breaches to the ICO within 72 hours, but you cannot report what you do not detect. The average time to detect a breach without MDR is measured in months, while MDR reduces this to minutes. It also provides the forensic evidence required to prove to regulators that “appropriate technical measures” were in place.
Insurers are tightening requirements, with many policies now mandating 24/7 monitoring. Without MDR, your business may face higher premiums and you may also be ineligible for a payout after a claim.
Microbyte ensures UK data remains within the UK, and navigates the US CLOUD Act, so we can ensure data residency aligns with your compliance obligations, creating confidence for clients in legal and finance sectors.
For most SMEs, building a 24/7 Security Operations Centre (SOC) is not practical.
Staffing a SOC 24/7/365 requires a minimum of 8 to 12 analysts to cover shifts, holidays, and sickness. In the UK, these salary costs alone often exceed £670,000 per year.
Managed MDR provides access to full SOC capability, but is charged as a monthly subscription per user. You gain enterprise-level security without the management headache, shifting security from a capital expenditure to an operational expense.

We deploy sensors via remote management tools, so no reboots are required.

The system runs in learning mode to establish "normal" network activity patterns.

Analysts filter out false positives specific to your environment.

We enable automated containment for high-confidence threats like ransomware.

We establish "Ask-to-Act" protocols for sensitive servers, where human approval is required before isolation actions are carried out on critical infrastructure.
Microbyte provides MDR within an existing managed IT relationship to reduce response friction during incidents.
Our SOC utilises physical teams in Peterborough, Dubai, and Los Angeles, which means someone is always watching your systems, even when your team is offline. So, when it is 3 AM in the UK, our international teams are still active.
We act as a Managed Security Service Provider (MSSP) with integrated IT support. We provide visibility into “Shadow IT” and detect unauthorised AI usage, to ensure governance over your data.
We align with our “Stamp Out Support” philosophy, where proactive detection prevents the “fire” of a full breach. This eliminates the downtime associated with reactive support tickets.
The modern IT threat landscape now includes active extortion and data theft, and passive defences cannot stop these human-operated attacks. Managed Detection and Response provides the active defence required to secure your data. It satisfies regulatory requirements for breach reporting, ensures eligibility for cyber insurance, and most importantly, prevents the catastrophic downtime that destroys SME value.
