Managed Security Services
for UK Organisations
UK-based Security Operations Centre services for organisations that cannot afford for threats to go undetected overnight. CREST-accredited. From as low as £900/month.
No sales pressure. A senior analyst will respond within one working day.
Managed SOC, MDR, Incident Response
& Threat Hunting
Four integrated defensive capabilities delivered by a single UK-based, CREST-accredited team. No offshore handoffs. No anonymous NOC.
Resilien by Precursor is our managed security service, delivered by the UK-based analysts in our Newcastle SOC. Our managed SOC and managed detection and response (MDR) capabilities bring together continuous monitoring, human investigation and agreed response actions from £900/month, with your final quote based on scope. Specialist incident response retainers and additional threat hunting can be scoped separately.
Building an in-house SOC is hugely expensive. SOC as a Service through Resilien delivers equivalent or greater coverage at a fraction of the cost, with CREST-accredited UK-based analysts, 200+ custom-built detection use cases, and no offshoring of work.
Operational Performance You Can Hold Us To
Every SLA below is contractually guaranteed. Not a marketing claim.
UK-Based SOC Coverage
Human analyst coverage every hour of every day, from our UK facility. No offshore handoffs, no overnight backlogs.
Incident Commander
Retained clients have a named CREST-accredited responder on call. One number. Immediate mobilisation.
Detection Use Cases
Custom-built detection rules mapped to MITRE ATT&CK across common and bespoke platforms.
Controls
Offensive Findings Feed
Directly Into Detection.
Our penetration testers brief the SOC on live attack patterns. Vulnerabilities found in your pen test feed directly into detection rules. The SOC uses MITRE ATT&CK to map coverage. The offensive team tests that coverage. No other UK provider runs this closed-loop model from a single team.

Findings from pen tests feed directly into SOC detection rules within 48 hours.
Cloud Monitoring
AWS, Azure, and Microsoft 365 monitoring integrated with your SOC coverage.
Red Team Operations
Test whether the SOC detects realistic, multi-stage attack simulations.
EdgeProtect ASM
Continuous attack surface monitoring between annual penetration tests.

Resilien Security Operations Centre (SOC)
From £900/month, scoped to your environment
If your cyber insurer, an auditor, or a client contract requires 24/7 security monitoring, this is what that means. Resilien Managed SOC monitors your agreed logs, network traffic, and cloud environments around the clock. When a confirmed threat is identified, a named analyst escalates immediately.
- 24/7/365 UK-based analyst coverage
- SIEM management and log ingestion: Microsoft, Sentinel and Elastic SIEMs
- Compliance reporting for ISO 27001, Cyber Essentials Plus, NIS2
- No infrastructure investment required
Consider this: If your cyber insurer declines your renewal claim because you could not demonstrate continuous security monitoring was active at the time of the incident, policy exclusions for inadequate monitoring are increasingly common in 2026.
Resilien Managed Detection and Response (MDR)
From £900/month, scoped to your environment
Resilien MDR brings human investigation and response to your security tools. Precursor analysts monitor your Microsoft Defender, SentinelOne, or CrowdStrike environment 24/7, investigating alerts and containing confirmed threats within your agreed response scope. Identity, network and cloud telemetry can be connected to build the wider picture.
- Human analyst triage on every confirmed threat, 24/7/365
- Threat containment under pre-agreed response permissions
- Works with your existing EDR: no rip-and-replace required
- Bring Your Own EDR or we deploy our recommended stack
Consider this: If your EDR fires a critical alert at 2 AM on a Bank Holiday weekend and nobody responds, the average dwell time for ransomware operators before payload deployment is 5 days: plenty of time to exfiltrate data before encryption begins.
Cyber Incident Response
Retainer & emergency call-outs available
Found encrypted files? Suspicious logins? Active threat actor behaviour? Call us now. CREST-accredited responders available 24/7. Retainer clients have a named incident commander on call. Emergency call-outs available without a prior retainer.
- Named incident commander mobilised immediately for retained clients
- Containment, digital forensics, and evidence preservation
- ICO breach notification support within the 72-hour GDPR window
- Ransomware negotiation and recovery coordination
Consider this: If you cannot identify and contain the attacker within 72 hours, under UK GDPR you must notify the ICO of a personal data breach. Missing that window carries fines of up to 4% of global annual turnover.
Threat Hunting
Quarterly engagements available
Attackers operating inside your network can have dwell times as low as 30 minutes before detonating ransomware. Threat hunting finds them before they find your backup servers. Our analysts run hypothesis-driven investigations using MITRE ATT&CK methodology against your environment.
- MITRE ATT&CK-aligned hunting methodology
- Credential abuse and lateral movement detection
- C2 beaconing identification and dark web exposure checks
- Available standalone or integrated with Managed SOC
Consider this: If an attacker is already inside your network, the time between initial compromise and ransomware deployment can be alarmingly short. Threat hunting finds them before they find your backup servers.
What Does "24/7 Monitoring" Actually Require?
If your cyber insurer, ISO 27001 auditor, or a client contract has asked for "24/7 monitoring": here is what that means in practice.
Log Collection
Collection from your endpoints, firewall, and cloud environments including AWS CloudTrail, Azure Monitor, and Microsoft 365.
SIEM Correlation
A SIEM platform to correlate those logs into meaningful alerts, filtering noise from signal.
Human Analyst Triage
Human analysts available around the clock to review and triage those alerts. Automated tools alone do not satisfy this requirement.
Defined Escalation Path
A documented, tested escalation procedure when a confirmed threat is identified. Including a named contact and response SLA.
Compliance Reporting
Reporting that demonstrates monitoring was active and effective. Required for ISO 27001 A.8.16, Cyber Essentials Plus, DORA, and NIS2.

Talk to a SOC Analyst, Not a Sales Team
Whether you need 24/7 monitoring, a response retainer, or you are evaluating build vs. buy for your security operations function: the right place to start is a conversation with the analysts who will actually be watching your environment. No discovery calls routed through BDRs. You speak with a senior analyst on the first call.
