Cloud Security Posture: Essential Risk Assessment Checklist

Most cloud incidents do not start with a clever exploit. They start with a storage container someone made public for a demo, an access key committed to a repository years ago, or logging switched on in one region and never in the other three. A cloud security posture assessment is the structured way of finding all of that before somebody else does. This checklist walks the whole engagement in order: scoping and read-only access, the technical domains worth reviewing, how to score findings so the list is defensible, whether to use native tooling or a dedicated platform, and what the work realistically costs in money and elapsed time.

rto and rpo explained business calculator a single hourglass on plinth

RTO and RPO Explained: Simple Calculator to Avoid Risk

RTO and RPO are the two numbers that decide what a recovery plan is allowed to cost, and most organisations set them without ever pricing the alternatives. This guide explains what each number really measures, where the figures should come from, and then gives you a five-input business calculator that converts hourly downtime cost, hourly data loss cost and failure frequency into a total cost of risk for every recovery tier. It includes a blank worksheet, a fully worked example on a sixty-person firm, indicative UK costs for backup, pilot light, warm standby and active-active, and the testing discipline that turns a target into a fact.

Backup vs Disaster Recovery: Simple Guide to Avoid Downtime

Backup, disaster recovery and high availability get used as though they were interchangeable, and they are not. A backup is a copy of your data you can go back to. Disaster recovery is the plan and environment that get a service running again somewhere else. High availability is the redundancy that stops a component failure becoming an outage at all. This guide sets out what each layer really protects against, where backup and disaster recovery genuinely diverge, how RTO and RPO drive the whole decision, what the three approaches cost a UK business in practice, how ransomware has changed the arithmetic, and a five-step framework for deciding which workload deserves which layer.

Cloud Exit Strategy: Proven Guide to Avoid Lock-In Risk

Almost every organisation agrees a cloud exit strategy is sensible and almost none holds a tested one. This guide sets out where lock-in genuinely comes from, what the four realistic exit routes cost in money and elapsed time, how egress charges and the new switching rules actually work, which architecture decisions keep the door open cheaply, what exit rights belong in the contract, and how to rehearse the plan so it becomes a capability rather than a filing-cabinet artefact. The point is rarely to leave. It is to be credibly able to leave.

azure landing zone implementation checklist a cube on round landing pad

Azure Landing Zone Checklist: Proven Steps to Avoid Risk

An Azure landing zone is the set of decisions you make once and live with for a decade: the tenant, the management group hierarchy, the identity model, the network topology, the policy baseline and the way workloads get their own subscriptions. Get them roughly right and every project afterwards is faster. Get them wrong and you pay for it in a remediation programme two years later. This checklist walks the implementation in order, explains which decisions are expensive to reverse, compares the deployment paths, and sets out what the build realistically costs in money, effort and elapsed time.

AWS vs Azure for UK SMEs: Essential Guide to Avoid Risk

AWS vs Azure is rarely a technology question for a UK SME, because both platforms will run the workload perfectly well. The decision is about money, people and exit. This guide compares the two on the things that actually move the answer: how each bill is built, the costs that never appear in a pricing calculator, the Microsoft licensing effect that quietly decides most UK cases, what the skills market looks like when you try to hire, how UK data residency and compliance work on each side, what leaving would really cost, and a weighted scoring framework you can fill in with your own numbers.

Cloud Migration Business Case: Proven Guide to Win Approval

A cloud migration business case fails when infrastructure people write for finance people and the translation never happens. This guide is that translation layer: how to build an on-premises baseline that survives challenge, how to cost the cloud side without wishful thinking, where three-year benefit genuinely comes from, how to model payback and net present value against a 3.5% discount rate, how to stress-test the answer so a 30% overrun still clears the hurdle, and how to compress the whole thing onto one page a board will approve.

ai assurance vs ai governance a two interlocking puzzle blocks

AI Assurance vs AI Governance: Essential Guide to Avoid Risk

AI governance sets the rules, roles and decision rights for the AI you run. AI assurance is the evidence that those rules were followed and that the system behaves as claimed. The two words are used interchangeably, and the confusion costs money: policies nobody tests, or tests nobody asked for. This guide separates them cleanly with a side-by-side comparison table, the assurance techniques that actually produce evidence a buyer or regulator will accept, a RACI grid for who owns what, what the UK’s assurance-led approach and the EU AI Act each demand, realistic cost profiles, a 90-day plan to stand both up, and the mistakes that make an assurance programme worthless.

Prompt Injection Risk: Essential Safe Assessment Guide

Prompt injection is the one attack class against business AI that has no structural fix, because instructions and data reach a language model through the same channel. This guide turns that into something you can manage: where injected instructions actually enter a business system, how to scope an assessment so it finishes in days, a ten-question likelihood and impact matrix anchored to observable facts, a control map showing which measures leave a low residual and which depend on the model behaving, how to build an injection corpus and test the boundary rather than the model, how to record findings in a register an auditor can follow, who owns the risk and what UK and EU regulators expect, realistic costs, and a 90-day plan.

AI Agent Security: Essential Guide to Safe Tool Access

The moment you connect a language model to a ticketing API, a finance system, a mailbox or a shell, you stop shipping a chat feature and start shipping a new class of privileged user. This guide covers the engineering work that keeps that user contained: how to classify and scope tools into risk tiers, why an agent needs its own identity and short-lived credentials rather than a shared service account, how to contain the blast radius of a single compromised run with sandboxing and default-deny egress, where to place human approval gates so they are decisive rather than theatre, what actually works against indirect prompt injection arriving through retrieved content, what to log so an incident is investigable, how to test the controls before launch, and a 90-day rollout plan with realistic costs and named owners.
