We are small, but grand ambitious
We're the Microsoft security specialists for organisations of 50-500 employees who need expert protection but can't justify hiring 6-8 SOC analysts.
Book Free Security AssessmentWhy Falconer Security Exists
Your organisation runs on Microsoft 365 and Azure. You know security matters - every headline about ransomware and data breaches proves that.
But hiring a full security team isn't realistic. The average Security Operations Centre requires 6-8 analysts working around the clock, costing over half a million pounds annually. Add a SOC manager, security engineers, and ongoing training, and you're looking at well over a million per year.
Meanwhile, off-the-shelf "security solutions" don't account for Microsoft's unique security architecture. Generic MSSPs treat Microsoft 365 like any other cloud platform, missing the native security capabilities built into your existing licences.
You're caught in the middle: too large to ignore security, too small to build a dedicated team.
That's the gap we fill.
How We're Different
Microsoft-Specialised, Not Microsoft-Compatible
The difference
Most MSSPs learn Microsoft security as an afterthought, adapting their generic playbooks to accommodate M365 and Azure. We started with Microsoft security. Our entire service architecture is built around Microsoft Sentinel, Defender suite, Entra ID, and Azure Security Centre. We don't use third-party tools requiring complex integrations - we optimise the security capabilities you already own.
Built for Organisations of 50-500 Employees
The difference
Enterprise-focused MSSPs sell you a scaled-down version of their enterprise offering. Features you don't need, complexity you can't manage, pricing you can't justify. We design every service tier specifically for SMB environments. Right-sized monitoring, practical implementation timelines, transparent pricing, and outcomes that matter to growing businesses.
Expert Deployment + Ongoing Optimisation
The difference
Many security vendors deploy a tool, hand you documentation, and disappear. Months later, costs spiral, alerts overwhelm your team, and real threats slip through unnoticed. We deploy, optimise, tune, and continuously improve your security posture. Detection rules refined based on your environment. False positive reduction through intelligent baseline tuning. Cost optimisation that typically reduces SIEM expenses by 30-40%.
What We Do
Microsoft 365 Security Assessment

You Run on Microsoft Infrastructure
Your primary systems are Microsoft 365 and Azure. You may use other tools, but Microsoft is your foundation.
You're in the Security Gap
Too large to ignore security (50-500 employees), too small to justify hiring a full SOC team. You need expert protection at SMB scale.
You Value Expertise Over Marketing
You want security that works, not security that sounds impressive. You'd rather have a well-configured Microsoft Defender than an expensive third-party EDR that duplicates native capabilities.
We've delivered security services for organisations in:
Common thread: Microsoft 365 or Azure infrastructure, 50-500 employees, need for expert security without enterprise-scale investment.
Built by Microsoft Security Specialists
Falconer Security was founded by security professionals who spent years implementing Microsoft security architectures for enterprise organisations - then realised the most underserved market was SMBs.
Enterprises have budgets, internal teams, and vendor relationships. Small businesses use basic antivirus and hope for the best. But organisations in the middle - growing businesses with real security needs - were stuck choosing between overpriced enterprise solutions and inadequate SMB tools. We built Falconer Security to serve that gap.

Track Record
What to Expect When Working With Falconer Security
Discovery & Assessment
We start every engagement with comprehensive discovery. Review current Microsoft security posture, identify immediate risks and gaps, understand your business context and risk tolerance, and assess licensing optimisation opportunities - you may already own security tools you're not using.
Strategy & Planning
Based on assessment findings, we develop implementation strategy. Prioritise improvements by risk and impact, define quick wins (0-30 days) vs longer-term initiatives, clarify roles, and establish success metrics and reporting cadence.
Implementation
We deploy, configure, and optimise based on agreed roadmap. Deploy security tools (Sentinel, Defender optimisations), build custom detection rules for your environment, create automated response playbooks, tune alert thresholds to minimise false positives, and document configurations and runbooks.
Ongoing Optimisation
Security isn't set-and-forget. We continuously improve with weekly and monthly detection rule tuning, quarterly security reviews and posture assessments, proactive threat hunting (for MDR customers), cost optimisation as usage patterns evolve, and regular reporting on security metrics and incidents.
What Our Clients Say
"We attempted to deploy Microsoft Sentinel ourselves and spent 9 months drowning in alerts and spiralling costs. Falconer optimised our deployment in 3 weeks - costs down 64%, false positives down 80%, and we actually caught a PHI access attempt in the first month that our old setup would have missed."
Healthcare IT Director
"We needed 24/7 security monitoring but couldn't justify hiring 6 SOC analysts. Falconer's MDR service gave us enterprise-grade protection at a fraction of the cost. Mean time to detect threats went from weeks to hours."
Financial Services Operations Director
"The M365 security assessment paid for itself immediately. We discovered we were already licensed for Defender for Office 365 but hadn't configured it properly. Within 30 days, phishing emails reaching inboxes dropped 90%."
Technology CTO
A clear, streamlined process to secure your Microsoft 365 tenant.
Common Questions (FAQ)
Yes. While we’re EU-based, we serve organizations globally. Our services are delivered remotely (Microsoft security is cloud-based), and we work across time zones for 24/7 MDR coverage.
We work alongside many excellent IT providers. They handle infrastructure, devices, and day-to-day IT support. We handle security monitoring, threat detection, and incident response. Most IT providers appreciate having a security specialist partner rather than trying to build SOC capabilities internally.
Rarely. Most organizations already own robust security tools through their Microsoft licensing but aren’t using them effectively. We typically optimize what you have before recommending additional tools. This often reduces costs while improving security.
Initial security assessments typically start within 1-2 weeks. Managed Sentinel deployments take 2-4 weeks from kickoff to optimized production environment. Full MDR services begin monitoring within 3-4 weeks of engagement start.
Our sweet spot is 50-500 employees. Smaller organizations often don’t have the security needs or budget to justify our services. Larger organizations typically have internal security teams and different requirements. We specialize in the middle market that’s too often underserved.
Our assessment services are one-time engagements with no ongoing commitment. Managed services (Sentinel and MDR) are typically monthly subscriptions with 90-day initial terms, then month-to-month thereafter.
For Managed Sentinel customers: We tune your environment and provide incident response guidance, but your team handles actual response. For MDR customers: We handle the full incident lifecycle: detection, triage, investigation, containment, remediation, and post-incident reporting. Response times are contractually guaranteed.
