Networking, cloud, and the security that connects them.
TJBSEC.LTD — Managed Security Service Provider for networking, Microsoft Azure and M365, identity, endpoint and incident response.
TJB is a Managed Security Service Provider. We analyze the technical risk in your stack — networks, cloud, identity, endpoints — and engineer the response.
TJB is not a help-desk.
TJB is not a re-seller.
TJB is a risk-led engineering practice for the part of your stack that does not get a second chance.
Methodology over reaction.
Analyze
01We map the architecture, baseline normal behavior, and identify structural vulnerabilities before they are exploited. Risk is quantified mathematically, not emotionally.
Engineer
02We implement zero-trust perimeters, robust identity boundaries, and immutable backups. Security is built into the infrastructure as code, resilient by design.
React
03When incidents occur, our response is procedural, decisive, and rehearsed. We isolate threats in milliseconds and restore operations with forensic confidence.
Nine pillars of
technical defense.
Comprehensive security requires expertise across the entire attack surface. We manage these nine domains natively.
Network design & mgmt
Segmented architectures and zero-trust access. SD-WAN that does not fold when a circuit blinks.
Azure & M365
Conditional access, Entra ID, Defender for Cloud, and backups proven by restoring them.
SIEM & detection
Aggregated logs and correlated alerts tuned for signal, not vendor defaults.
Managed endpoint
Deployment, policy tuning, and host quarantine that fires before the user notices.
Identity & access
Phishing-resistant authentication, conditional access, and privileged access management.
Vulnerability mgmt
Continuous scanning, prioritized by exploitability, and closed — not shipped back as a PDF.
Firewall mgmt
Rules with reasons behind them. Segmentation, IDS/IPS, and VPN reviewed quarterly.
Backup & DR
Tested restores, immutable storage, and runbooks rehearsed before they are needed.
Incident response
When containment is the priority, TJB mobilizes for forensics, eviction, and recovery.
How we operate.
Retainer
01Ongoing, active management of your security posture. Continuous monitoring, configuration drift management, and guaranteed SLA response for incidents.
Project
02Discrete engineering engagements to overhaul specific domains: network rebuilds, cloud migrations, or zero-trust implementations.
Incident
03Immediate, aggressive intervention for active breaches. Containment, forensic analysis, and secure recovery.
Bespoke
04A focused engagement shaped around your environment: risk assessment, architecture, control engineering, or a problem that does not fit a standard package.
Tim Brewer
Principal · Founder · Est. 2024Built by an operator.
TJB was founded on a simple premise: generic IT services cannot provide actual security. Standard help-desks are optimized for ticket volume and user appeasement. Security requires friction, precision, and engineering discipline.
As Principal, Tim Brewer brings over two decades of enterprise architecture, incident response, and offensive security experience to bear on client networks.
We do not outsource our technical core. When a client faces a critical incident or requires a total architectural rebuild, the work is executed by seasoned engineers who understand the stakes.
