Private AI for UK Businesses: How to Use LLMs Without Exposing Company Data

The general, all-sector answer to the question every UK business is now asking: how do you get the benefit of large language models without feeding them things you are paid to protect? This guide defines what private AI actually means, maps the five deployment levels from business-tier chatbots to fully self-hosted open-weight models, sets the UK GDPR and confidentiality position, prices a 20-person worked example across all four buyable routes, covers RAG without exposure, the NCSC and OWASP security layer, vendor due diligence in eight questions, and finishes with a 90-day rollout plan.

Microsoft Copilot Agents: Security, Governance and Cost Guide

Copilot agents are the point at which Microsoft’s AI stops being an assistant that answers questions and becomes software that acts on your behalf. That shift is small in the interface and enormous everywhere else. An assistant that drafts an email is a productivity feature. An agent that reads a mailbox, decides something and sends […]

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 Red-Teaming: Essential Tests to Run Before a Safe Launch

Most AI systems reach launch having been tested only by people trying to make them work. Adversarial testing asks the other question: what happens when someone actively tries to make the system misbehave. This guide sets out what to test before go-live — how to scope the exercise and define harm in your own domain, the five attack classes that matter for business deployments, whether to run it internally, buy it in or automate it, how to score findings so severity cannot be renegotiated after the fact, which fixes actually hold, what the work costs in person-days and pounds, and the evidence pack that answers an enterprise security questionnaire and maps onto the EU AI Act, ISO 42001 and the NIST AI Risk Management Framework.

Brex AI Agent Policy: Building AI Governance by Observing Real Agent Behavior

As artificial intelligence rapidly evolves from simple chatbots into autonomous software agents capable of planning, reasoning, making decisions, and interacting with enterprise systems, organizations face a new challenge: how do you govern AI agents without limiting their ability to innovate? Traditional governance models rely on predefined policies, fixed rules, and extensive documentation before deployment. However, […]

AI Can Be an Ally in Rooting Out Ransomware Threats

AI ransomware detection and prevention represents a fundamental shift in cybersecurity strategy. Instead of waiting for known attack signatures or relying on static threat intelligence feeds, AI-powered systems analyze behavioral patterns, detect anomalies in real time, and neutralize threats across the attack chain. This article explores how AI is becoming an indispensable ally in the […]
