Infrastructure Security
Secure the foundation of your digital ecosystem across cloud, on-premise and hybrid infrastructure
Infrastructure Security
Infrastructure Security refers to the set of practices, technologies and controls used to protect the underlying systems that support your applications, services and data. It covers everything from cloud and on-premise environments to networks, servers, containers and endpoints.

The benefits of getting Infrastructure Security right
Prevent unauthorised access and data breaches
Protect systems and services from internal and external threats through access control, segmentation and monitoring.
Maintain compliance with regulatory standards
Align infrastructure with the requirements of GDPR, NIS2, ISO 27001 and industry-specific regulations through well-architected infrastructure controls.
Enable secure digital transformation
Support agile development, cloud adoption, DevOps and remote operations without compromising on security posture.
Improve visibility and control
Centralised monitoring, logging and alerting provide faster response times and root-cause analysis.
Resilience against modern attack vectors
Harden systems against common exploits such as ransomware, misconfigurations and privilege escalation.
What’s holding your infrastructure security back?
Let’s explore how your infrastructure security can reduce risk, support compliance and create space for innovation. Talk to the Claria team and start building a security foundation that works for the long term.
Get in touchHow can we help you and what do we do?
At Claria, we help organisations design, implement and maintain infrastructure that’s not only high-performing, but resilient by default.
Our Infrastructure Security services
Infrastructure security assessments
Identify weaknesses and benchmark your environment against frameworks like NIST, CIS and ISO 27001.
Logging, alerting and SIEM integration
Design and deployment of secure monitoring frameworks.
Secure configuration and hardening
Best practice implementation for cloud platforms (AWS, Azure, GCP), operating systems and network devices.
Team augmentation
Security engineers, cloud architects and DevSecOps specialists who work alongside your internal teams during critical projects or ongoing operations.
Cloud security posture management (CSPM)
Continuous monitoring and remediation of misconfigurations across cloud workloads.
Managed Services & Support
Ongoing monitoring, updates, incident response and performance tuning, aligned to your SLA and compliance requirements.
Network segmentation and firewall policy design
Limiting lateral movement and minimising blast radius.
Training and Enablement
Customised sessions for platform teams, security analysts or DevOps roles, covering hardening, identity, automation, compliance and more.
Secrets management and identity control
Enforcing least privilege through IAM, secrets vaulting and federated identity.
Technology selection & Advisory
We help you evaluate and choose the right security technologies for your infrastructure from CSPM tools and endpoint protection to firewalls, secrets management and SIEM platforms.
The technologies we use at Claria
You don’t need more tools. You need the right ones, used the right way. Security tooling only delivers value when it fits your infrastructure, your teams and your pace of change. At Claria, we don’t push brands, we work with proven technologies that align with how your environments actually operate.
We work with the following technologies
Cloud and data platforms
IAM & secrets management
Infrastructure-as-code security
On and response
Baseline configuration and control frameworks
+ OS-level hardening scripts and policies
Monitoring and response
Configuration benchmarks
+ OS-level hardening scripts
How to tackle these projects?
What works today may be outpaced tomorrow by scale, complexity or threat evolution. That’s why we approach infrastructure security as a living practice: one that adapts with your environments, integrates with your delivery pipelines and evolves alongside your architecture.
Get in touchHere’s how we typically structure these initiatives:
1. Assess current risk posture
Start with an inventory and assessment of existing infrastructure components, identifying misconfigurations, exposed services and compliance gaps.
2. Apply defence-in-depth principles
Layer controls across perimeter, network, host and identity layers to reduce risk from all angles.
3. Automate wherever possible
Use Infrastructure as Code (IaC) and Policy as Code (PaC) to enforce secure configurations at scale.
4. Establish baselines and alerting
Define normal behaviour and thresholds for anomalies and integrate them into SIEM tools.
5. Review and rotate access and credentials
Implement privileged access management (PAM), regular rotation and audit trails.
6. Continuously monitor and iterate
Security is not static, ensure your posture evolves alongside your infrastructure.
Common mistakes made in Infrastructure Security initiatives
We’ve seen it across industries: teams invest in security tools, write policies, even tick compliance boxes… but gaps remain. These are the missteps that tend to surface when something breaks and they’re almost always avoidable with the right foundations.
Here are some of the patterns we see when security is misaligned with how infrastructure actually runs.
Relying on default cloud settings
Defaults are rarely secure. Without hardening, cloud environments can be highly exposed.
Poor segmentation
Flat networks make it easy for attackers to move laterally once inside.
Lack of visibility and alerting
Without proper logging and monitoring, security incidents may go unnoticed.
Neglecting credentials and secrets
Hardcoded credentials or unmanaged secrets are common points of failure.
Treating cloud security the same as on-prem
Cloud requires a different approach, based on shared responsibility and dynamic assets.
Why choose Claria
We don’t secure infrastructure in theory. We do it in production.
At Claria, we understand that securing infrastructure isn’t about adding more controls, it’s about designing the right ones for the environment you already have and the one you're growing into.
We work with organisations that run critical systems across hybrid, cloud and legacy landscapes, helping them introduce structure without slowing down delivery. From design to deployment and long-term operation, we focus on the details that make infrastructure security effective, sustainable and understood across teams.
What sets us apart:
We embed security into real architectures, not abstract models
We build around your people, processes and operational realities
We’re technology-agnostic but deeply hands-on with leading platforms
We support not just the implementation, but also adoption, training and scaling
We make security something your teams can maintain, not just react to
