Raspberry Pi 5 (16GB) — Now In Stock

Every organisation handles sensitive data — customer records, financial reports, intellectual property — and all of it can walk out the door through email, cloud uploads, USB drives, or misconfiguration. Data Loss Prevention (DLP) technologies monitor, detect, and block the unauthorised movement of sensitive information. This guide covers DLP fundamentals, deployment models, policy design, and the Australian privacy considerations that make DLP relevant for local businesses.

When the database goes down, everything goes down. Whether it is an ERP system, a web application, or a point-of-sale platform, database availability underpins every transaction. This article explores the major approaches to database high availability — active-passive clustering, active-active replication, and automated failover — across SQL Server, PostgreSQL, and MySQL, with practical guidance on choosing the right architecture for your clients.

Ransomware operators now routinely target backup repositories before encrypting production data, knowing that an organisation without recoverable backups is far more likely to pay. Immutable backups — copies that cannot be altered or deleted for a defined retention period — are the most effective technical countermeasure. This guide explains the underlying technologies, compares air-gapped and immutable approaches, and walks through implementation with Veeam, QNAP, and major cloud platforms.

Storage capacity grows cheaper each year, but data grows faster. Deduplication and compression are the two foundational technologies that reduce the physical storage required for a given data set, cutting costs on disk, backup media, and replication bandwidth. This guide explains how deduplication and compression work, the trade-offs between inline and post-process approaches, and how leading backup and storage vendors implement these features.

Not all storage is created equal. Object storage, block storage, and file storage each address different workloads, performance requirements, and cost profiles. Choosing the wrong type can mean paying too much for capacity you do not need or suffering performance bottlenecks that cripple applications. This guide explains how each storage type works, when to use it, and how they compare on performance, scalability, and cost at scale.

Designing a business WiFi network means choosing an architecture: self-organising mesh, on-premises controller, or cloud-managed access points. Each approach offers different trade-offs in cost, scalability, roaming performance, and management complexity. This article breaks down mesh networking concepts, compares leading vendor platforms from Ubiquiti, Aruba, and Cisco Meraki, and explains the roaming standards that keep users connected as they move through a building.

When fibre is unavailable or too expensive to provision, wireless broadband fills the gap. Australian businesses now face a choice between 5G fixed wireless access, NBN fixed wireless, and traditional fibre for primary or failover connectivity. This guide compares latency, throughput, reliability, and cost across these options, with a focus on real-world use cases such as remote sites, pop-up offices, and automatic WAN failover.

Serverless computing lets you write code and deploy it while the cloud provider handles servers, scaling, and availability. Platforms like AWS Lambda, Azure Functions, and Google Cloud Functions power everything from API backends to data processing pipelines. But serverless is not a silver bullet — cold starts, vendor lock-in, and execution limits demand careful evaluation. This article explores where serverless excels, where it falls short, and how to adopt it.

Containers changed how applications are packaged, but managing hundreds of containers across multiple hosts requires orchestration. Kubernetes — originally developed by Google — has become the industry standard for deploying, scaling, and operating containerised workloads. This guide covers core concepts, managed offerings from the major cloud providers, resource planning, and honest guidance on when Kubernetes is and is not the right choice for your environment.

Shipping software reliably and frequently requires more than talented developers — it demands an automated pipeline that builds, tests, and deploys every change with minimal human intervention. CI/CD pipelines are the backbone of modern software delivery, catching defects early and enabling rapid releases. This article walks through each pipeline stage, compares popular platforms, and offers practical guidance for Australian IT teams building or refining their delivery workflows.

Manually provisioning servers and configuring networks through point-and-click consoles is slow, error-prone, and impossible to audit at scale. Infrastructure as Code (IaC) replaces those manual steps with version-controlled configuration files that describe your desired state, letting you spin up, modify, and tear down environments repeatably and reliably. This guide covers the core IaC concepts, compares the leading tools, and explains why MSPs and resellers should adopt IaC practices today.

Web applications are among the most exposed and frequently attacked assets in any organisation's IT environment. A Web Application Firewall (WAF) sits between users and web servers, inspecting HTTP traffic to block attacks such as SQL injection, cross-site scripting, and other OWASP Top 10 threats. This guide explains how WAFs work, compares cloud and on-premises deployment models, and reviews the leading solutions available to Australian IT resellers.

A Security Operations Centre is the nerve centre of an organisation's cyber defence, staffed by analysts who monitor, detect, investigate, and respond to threats around the clock. But building an in-house SOC is expensive and talent-scarce, while outsourcing to a Managed Security Service Provider means trusting a third party with your most sensitive data. This guide explores the build, buy, and hybrid models, helping Australian IT resellers advise clients on the right approach.

Vulnerability scanning and penetration testing are often mentioned in the same breath, but they serve fundamentally different purposes. Scanning identifies known weaknesses automatically, while penetration testing uses human expertise to simulate real-world attacks and chain vulnerabilities together. Understanding when to use each — and how they complement one another — is essential for any Australian IT reseller advising clients on their security posture.

Every server, firewall, endpoint and application generates log data, but without a way to collect, normalise and correlate that data in real time, threats slip through unnoticed. Security Information and Event Management (SIEM) platforms centralise logs and apply analytics to surface the incidents that matter. This guide explains how SIEM works, where it fits in a modern security operations workflow, and how Australian IT resellers can evaluate the leading platforms.

IPv4 addresses have been exhausted globally, and the Asia-Pacific region has been feeling the pinch for years. IPv6 — with its vast 128-bit address space — is the inevitable successor, yet adoption in Australian business networks remains patchy. This guide explains why IPv6 matters now, how dual-stack deployment works, address planning fundamentals, transition mechanisms like NAT64 and DNS64, and a practical roadmap for when and how to start planning.

Link Aggregation bundles multiple physical network links into a single logical connection, increasing throughput and providing failover if a cable or port fails. Whether you are connecting a server with dual NICs to a switch or linking two switches together, LACP (802.3ad) is the industry-standard protocol that makes it work. This guide covers static vs dynamic LAG, MLAG and vPC for multi-chassis aggregation, practical use cases, and common mistakes.

VLANs have long been the primary tool for segmenting networks, but they were designed for traffic management, not security. Modern threats move laterally — once inside a VLAN, an attacker can reach every device in that segment. Microsegmentation enforces granular security policies between individual workloads regardless of network location. This guide explores east-west traffic control, software-defined microsegmentation, and practical implementation strategies for Australian businesses.

The Border Gateway Protocol (BGP) is the routing protocol that holds the internet together. Every time a user in Sydney reaches a website hosted in London, BGP is responsible for selecting the path those packets take across dozens of autonomous networks. This guide introduces autonomous systems, the difference between iBGP and eBGP, path selection, peering versus transit, and why BGP matters for multi-homed Australian businesses.

Microsoft Teams has evolved from a chat and meeting tool into a full enterprise telephony platform capable of replacing traditional PBX systems. With Teams Phone licensing, businesses can make and receive PSTN calls directly from the Teams client — but the path from legacy PBX to Teams Phone involves critical decisions around calling plans, direct routing, operator connect, and SBC hardware. This guide covers every aspect of the migration for IT resellers deploying Teams Phone for their clients.

Many small businesses start with a consumer router from their ISP and never think about it again — until performance degrades, security incidents occur, or compliance requirements demand more. Understanding the difference between a consumer router, a business router, and an enterprise firewall helps you decide when it is time to upgrade and what to look for when you do.

Every organisation that runs its own applications and data must decide where to host its servers. The three main options — an on-premises server room, colocation in a data centre, and cloud hosting — each come with distinct trade-offs around cost, control, scalability, and compliance. This guide compares all three, breaks down the real costs, and helps you decide which approach fits your business.

Remote access has become a non-negotiable requirement for modern businesses. Whether staff are working from home, IT teams need to manage servers, or help desks need to troubleshoot end-user desktops, reliable and secure remote connectivity is essential. This guide compares traditional protocols like RDP and VNC with modern Zero Trust approaches, and explains the security considerations that should shape your choice.

Deploying WiFi without a site survey is like wiring a building without a floor plan — you might get lucky, but you will probably end up with dead spots, interference, and frustrated users. A proper wireless site survey measures the radio environment, identifies obstacles, and produces a data-driven AP placement plan. This guide walks through the types of surveys, the tools you need, and the most common mistakes to avoid.
