Security Engineering & Hardening

Closing attack paths, strengthening identity and cloud configurations, and building security foundations that withstand real adversaries.

Engineering stronger defences for modern environments

Security engineering is the foundation of a defensible environment. It is the work of ensuring that identity, cloud, networks, OT/IoT systems, and endpoints resist attack, support effective monitoring, and limit the blast radius when incidents occur.

Cyber Defence brings together engineers, penetration testers, cloud security specialists, incident responders, and detection engineers to design and implement practical, evidence-driven improvements to your security posture. Our work is grounded in real attack behaviour observed by our SOC365 teams and the Disrupt incident response unit.

Engineering for resilience, not just compliance

Many organisations focus on compliance checklists or theoretical best practice. Our approach is different. We engineer defences that hold up under real-world adversarial pressure – from commodity malware through to targeted identity compromise, cloud misconfiguration abuse, and lateral movement.

Security Engineering engagements can be one-off improvements, targeted uplift projects, or ongoing programmes aligned with your internal teams and technology roadmap.

Capabilities

What our Security Engineering team delivers

We strengthen identity, cloud, network, and OT environments with practical engineering that reduces risk and improves SOC visibility.

Identity & Access Hardening

Strengthening Azure AD/Microsoft 365, privileged access, MFA, conditional access, identity lifecycle, and administrative boundaries.

Cloud Security Engineering

Hardening Azure, AWS, and hybrid cloud environments, including IAM, virtual networks, storage, Key Vault, policies, and workload controls.

Network Segmentation & Zero Trust

Designing segmentation between IT, OT, cloud, and user environments; implementing Zero Trust access and secure remote access patterns.

Endpoint & EDR Configuration

Improving endpoint baselines, EDR configurations, Sysmon deployments, host logging, and defensive telemetry for SOC365 detection coverage.

OT & IoT Security Improvements

Strengthening industrial networks, IoT fleets, sensors, and operational systems with appropriate segmentation, monitoring, and hardening.

Secure Configuration & Hardening

Hardening servers, databases, applications, APIs, and supporting infrastructure across Windows and Linux estates.

Hardening across IT, cloud, OT & IoT

Modern environments are hybrid by default. Organisations now depend on identity systems, SaaS platforms, cloud workloads, data lakes, OT/ICS systems, IoT sensors, operational management tools, and legacy applications.

Cyber Defence engineering work spans all these domains. We help ensure that controls are consistent, that attack paths are understood and closed, and that monitoring reaches into the systems that matter most to safe and reliable operations.

Programmes

Engineering programmes we deliver

Our engineering engagements can be structured as focused projects or multi-month uplift programmes.

Identity Security Uplift

A comprehensive programme to harden identity, eliminate shadow privileges, enforce MFA and conditional access, and deploy strong administrative baselines.

Cloud Security Uplift

Review and hardening of Azure, AWS, or hybrid cloud implementations, including IAM, network, logging, storage, and workload security.

SOC Visibility & Logging Programme

Establishing a defensible logging and telemetry architecture for SOC365, including Sysmon, audit policies, EDR tuning, and cloud-native logging.

OT/IoT Security Programme

Mapping and segmenting OT networks, securing engineering workstations, improving monitoring, and addressing legacy system limitations.

Secure Remote Access & Zero Trust

Engineering of secure VPN, identity-bound access, device trust, conditional access, and logging for remote and hybrid workforces.

Application & API Security Hardening

Secure configuration, secrets management, key rotation, TLS configurations, API gateway security, and CI/CD security integration.

Collaborative approach

How we work with your teams

Security Engineering succeeds when it is collaborative. We work closely with infrastructure, cloud, DevOps, OT, and SOC teams to ensure changes are practical, well-documented, and embedded into day-to-day operations.

Engineering workshops

Hands-on sessions to review architecture, identify gaps, and design remediation aligned with your operational reality.

Joint configuration & pairing sessions

Working directly with your engineers to configure systems, validate changes, and apply security baselines.

Documentation & standards

Clear guidance, baselines, configuration templates, and reference architectures tailored to your environment.

Operational playbooks

Building engineering playbooks for identity, cloud, endpoint, and OT environments to support SOC365 and IR workflows.

Continuous improvement cycles

Regular reviews of security posture, attack paths, detections, and engineering gaps based on real adversary behaviour.

Integration with SOC365

Ensuring that engineering outputs directly enhance detection coverage, logging quality, and incident response readiness.

Outcomes

What organisations gain from Security Engineering

Security Engineering transforms environments, making them more resilient to real attacks and easier to monitor effectively.

Closed attack paths

Privilege escalation routes, misconfigurations, exposed services, and insecure defaults are identified and remediated.

Improved detection & telemetry

Better logs, cleaner signals, and more consistent baselines enable SOC365 to detect attacks earlier.

Stronger cloud & identity posture

Hardened identity and cloud configurations reduce the risk of lateral movement or account compromise.

Better OT/IoT resilience

Segmentation, access control, and secure connectivity protect sensitive operational systems.

Reduced incident impact

Better-prepared environments recover faster and contain intrusions with less disruption.

Clear, repeatable security practices

Engineering improvements become part of your standard operations, not one-off remediation tasks.
