Outsourced cyber security
— everything managed for you
NextGen EDR (Endpoint Detection & Response)
Microsoft Defender for Business or equivalent — AI-powered behavioural detection on every device. Detects ransomware, fileless malware, and novel threats that signature-based AV misses.
Dark Web Monitoring
24/7 scanning of dark web marketplaces and breach databases for your business credentials. Immediate alert if passwords are compromised — before attackers use them.
Patch Management
Automated patching of Windows, macOS, third-party software, and network firmware — applied within 14 days of release (Cyber Essentials requirement). No more missed critical updates.
Email Security & Anti-Phishing
Microsoft Defender for Office 365, Safe Links, Safe Attachments, DMARC/DKIM/SPF configuration, and simulated phishing campaigns with staff training.
Security Awareness Training
Monthly phishing simulations and micro-training modules for all staff. Research shows this reduces successful phishing attacks by 60–80% within 12 months.
Microsoft Secure Score Management
Monthly review and improvement of your Microsoft 365 Secure Score — systematically closing security gaps in your M365 configuration across all workloads.
Endpoint detection & response
(EDR) for London businesses
Endpoint Detection and Response (EDR) is the successor to traditional antivirus — and is now the minimum standard for business endpoint security. While legacy AV relies on signatures (known threat databases), EDR uses AI and behavioural analysis to detect threats based on what they do, not what they look like.
This matters because modern ransomware, fileless malware, and advanced persistent threats are specifically engineered to evade signature-based detection. An EDR solution watching for ransomware behaviour (mass file encryption, shadow copy deletion, lateral movement) will catch a novel attack; standard AV will not.
Managed EDR in London: Deploying EDR is only part of the answer — the alerts it generates need to be monitored and acted upon 24/7. Coreitech's managed EDR service deploys Microsoft Defender for Business across all your devices, integrates with our SOC monitoring platform, and ensures every alert is triaged and responded to — not just logged.
EDR is now a Cyber Essentials-aligned requirement (via "malware protection" control) and is increasingly required by cyber insurers as a minimum condition of coverage.
Why standard AV is no longer enough
| Feature | Managed EDR | Standard AV |
|---|---|---|
| Detection method | AI behavioural analysis | Signature database |
| Novel/zero-day threats | ✓ Detects | ✗ Misses |
| Fileless malware | ✓ Detects | ✗ Misses |
| Ransomware behaviour | ✓ Auto-isolates device | ✗ Often too late |
| Incident investigation | ✓ Full forensic timeline | ✗ Limited logs |
| Centralised visibility | ✓ All devices, one pane | ✗ Per-device only |
| Cyber Essentials aligned | ✓ Yes | ⚠ Partially |

Outsourced cyber security & MSSP
questions answered
Q.What is outsourced cyber security?
Outsourced cyber security (also called managed cyber security or MSSP — Managed Security Service Provider) means hiring a specialist security company to manage your business's entire cyber protection. Instead of employing in-house security staff or relying on basic antivirus, you get a full team of security engineers monitoring, managing, and responding to threats for a fixed monthly fee. Coreitech provides outsourced cyber security for London businesses from £15/user/month.
Q.What is a managed security service provider (MSSP)?
A managed security service provider (MSSP) is a company specialising in outsourced security services — typically including 24/7 SOC monitoring, threat detection, incident response, EDR management, email security, patch management, and compliance reporting. Unlike a general managed IT provider (MSP), an MSSP's primary focus is security operations. Coreitech operates as both MSP and MSSP — providing fully integrated IT support and security management under one contract.
Q.How much does outsourced cyber security cost for a UK SME?
For most UK SMEs, outsourced cyber security costs £15–£35 per user per month depending on services included. Coreitech's Security Essentials plan (£15/user/month) covers EDR, patch management, dark web monitoring, and email filtering. Security Plus (£30/user/month) adds 24/7 SOC monitoring, phishing simulations, and incident response. This compares to £50,000–£80,000+ per year for a single in-house security engineer, without 24/7 coverage or the breadth of expertise.
Q.Is outsourced cyber security suitable for small businesses?
Absolutely — and it's particularly important for small businesses. 43% of all UK cyber attacks target organisations with under 250 staff because they're seen as easier targets than enterprises. Most small businesses lack the resources to maintain in-house security expertise, 24/7 monitoring, or up-to-date security tooling. Coreitech's managed security packages are specifically designed for businesses of 5–200 users — no enterprise contracts, no complex onboarding.
Q.What is endpoint detection and response (EDR)?
EDR (Endpoint Detection and Response) is an advanced security technology deployed on every device (endpoint) in your organisation. Unlike traditional antivirus — which only detects known threats using signatures — EDR uses AI and behavioural analysis to detect novel threats including ransomware, fileless malware, and advanced persistent threats. When a threat is detected, EDR can automatically isolate the infected device to prevent spread. Microsoft Defender for Business (included in Microsoft 365 Business Premium) provides EDR — Coreitech manages and monitors it as part of outsourced cyber security.
Q.Do I need cyber security if I already use Microsoft 365?
Microsoft 365 includes security features, but three issues commonly leave businesses exposed: (1) the security tools included depend on your licence — Business Standard is missing EDR and advanced email security; (2) even Business Premium tools require expert configuration to be effective — most SMEs have default settings that leave significant gaps; (3) the tools need active monitoring — deployed but unmonitored security tools provide false assurance. Coreitech properly configures your Microsoft security tools, monitors alerts 24/7, and responds to incidents.
Q.How quickly can outsourced cyber security be set up?
Coreitech can typically deploy basic outsourced cyber security tools (EDR, email security configuration, dark web monitoring) within 48–72 hours. Full onboarding including staff training programme setup takes approximately 1 week. We handle all deployment — there is no significant IT burden on your team during the process.
