Network Engineering for High Availability & Security

A resilient and secure network starts with secure-by-design network architecture. It involves network segmentation by segregating the IT and OT systems to prevent lateral movements, so that systems can be isolated in an event of breach and the compromise can be contained.

The security landscape is hardened with firewalls, encryption, and Identity and Access (IAM) solutions like IXID, that govern and centrally manage policies for authenticated and authorised access with user privilege management control. When it comes to oversight, situational awareness through visibility tools plays an important role, scanning regularly all high value servers and other critical device components, giving granular data to analyse, and alerting for deviations.

The key is to prevent outages, mitigate risks, and respond to events proactively, before anything escalates. So, governance and compliance not only become guidelines but also the best practices to design network security.

We do both and our approach is finding fit-for-purpose solutions. We tailor the design to your needs instead of using one-size-fits all structure.

For a new network design architecture, we take lead on building the design for you from the group up, based on understanding your specific IT-OT environment and objectives.

In case of existing infrastructure, we start by assessing the existing systems, platforms, and processes, identifying gaps, working with you to remediate. We factor in the legacy technology, any limitations, and potential impact of future implementation before actioning changes.

We work on developing clear visibility into your architecture, allowing smart traffic distribution and pattern analysis to ensure efficient data flow and communication between devices, ports, and sites. We consider these when working on topology mapping and network diagrams.

Our entire process revolves around providing you a custom-built design for your infrastructure, which remains secure, scalable, and compatible with changes for future needs.

We do network health reporting and analysis as part of our support services after the network is operational, post design and implementation. We start with establishing performance metrics and benchmarks. Once we standardise and baseline the metrics, we setup alert generation for deviances, to conduct root-cause analysis of performance when it drops below expected levels.

The key metrics involves latency, packet loss, bandwidth utilisation, reachability and connection quality. We maintain network performance data on centralised platforms that consolidate and correlate information, to give you a composite picture of how reliable your network delivery is for the users and devices dependant on it and troubleshoot before potential risks arise. Identifying anomalies, automated discovery, granular data analysis, and regular security checks allow for proactive incident response. Our network audits give you informed and proactive control over your network.

We provide network health reporting and analysis as part of ongoing support services, available once the network is operational. We start with establishing performance metrics and benchmarks. Once we standardise and baseline the metrics, we configure alert generation for deviances, to conduct root-cause analysis of performance when it drops below expected levels.

The key metrics involve latency, packet loss, bandwidth utilisation, reachability, and connection quality. We maintain network performance data on centralised platforms that consolidate and correlate information, giving you a composite picture of your network and device health, and the ability to troubleshoot before risks are realised. Identifying anomalies, automated discovery, granular data analysis, and regular security checks allow for proactive incident response. Our network audits give you informed and proactive control over your network.

We combine a multitude of tools, processes, and systems to provide a high availability network.

It involves seamless traffic routing, security breach prevention, and backup infrastructure.

We design networks that eliminate single point of failure, with redundancy in every network layer. If one connection, path, or device fails, another takes over with failover mechanisms. Load balancing is enabled to distribute traffic efficiently and maintain consistent performance during overloads, to prevent bottlenecks. Replication allows duplicating resources to maintain interdependencies of critical systems. Data Lost Prevention (DLP) systems help with detecting, monitoring, and prevent unauthorised access of sensitive data, shielding critical networks with cyber security protocols.

In addition to network architecture design, we provide a range of on-going support services to assist with the management of an operational network. We handle network health monitoring and network performance analysis, including diagnosing for VPN tunnel obstructions, backup failures, firewall blockage, and so on. We offer robust access control through our Identity and Access Management (IAM) solution, IXID, ensuring only right people get access to your sites, devices, and applications, with authentication, authorisation, and least privilege management giving centralise managed control.

For governance and compliance, we identify security gaps in your network infrastructure by conducting cyber security audits and assessing against compliance practices of the AESCSF regulatory framework.

We have IT and OT ICS expertise with specialist consultancy to critical infrastructure businesses along with risk management services. We offer situational awareness with ongoing network visibility, threat detection and response, alerting, and host monitoring to mitigate risks and threats before they become incidents.

We do holistic support with end-to-end network solutions, cyber security, and compliance for resilient infrastructure.
