Cyberattacks do not wait for office hours, and most organisations without a dedicated round the clock security operations centre are effectively blind between the point an attacker gets in and the point someone notices. Industry estimates still put average dwell time at around two weeks, and for many mid-sized organisations building an internal SOC to close that gap is neither affordable nor realistic. This guide sets out the leading managed detection and response (MDR) provi

Email remains the single most common way attackers get into an organisation, and business email compromise alone cost organisations 2.9 billion US dollars in reported losses according to the FBI's Internet Crime Complaint Center - more than ransomware, more than any other cybercrime category the IC3 tracks. The attacks driving that number are frequently not malware at all: a plain-text message that looks exactly like it came from your CFO, your law firm, or your largest suppl

The VPN-and-branch-firewall model that carried enterprise networking for two decades assumes a world where users sit inside an office and applications sit inside a data centre. Neither is true for most organisations any more, and Secure Access Service Edge (SASE) exists specifically to close that gap - converging networking and security into a single, cloud-delivered service that follows the user rather than the other way round. SASE has matured from a framework into a genuin

Most organisations now run production workloads across two or three cloud providers at once, and the misconfigurations that cause the majority of cloud breaches - an open storage bucket, an over-permissioned identity, an unpatched container image - rarely show up in a traditional firewall or endpoint console. Cloud security software exists specifically to close that gap, and 2026 has been the most consequential year the category has had. The standalone CSPM tool has effective

A security operations team is only as good as the data it can see and correlate, and that is the job a SIEM exists to do - pulling logs, alerts, and telemetry from across the estate into one place where a genuine attack pattern can be told apart from routine noise. Getting the platform wrong shows up later as either a breach missed in the noise, or a team of analysts drowning in alerts they cannot realistically work through. The SIEM market has gone through more structural ch

Most breaches still cross a network boundary at some point, and the firewall sitting at that boundary is either doing the job of an application-aware security control or quietly acting as a basic packet filter that has not kept pace with what modern attacks look like. Buyers who have not revisited their firewall estate in several years are often surprised by how far the category has moved. In 2026, the next-generation firewall has become one node in a wider security fabric ra

Ransomware and identity-based attacks now move from initial access to full compromise in minutes, and the endpoint remains the point where most of those attacks either get stopped or get through. Choosing the wrong platform, or the wrong tier of one, leaves a gap that most security teams only discover after an incident. The category has changed shape again in 2026. Detection has moved from single-endpoint EDR to correlated XDR that pulls in identity, cloud, and network signal

If you are looking at endpoint management or cybersecurity platforms, you have almost certainly come across Tanium. The company has built its reputation on real time visibility and control across millions of endpoints, and it now positions itself at the centre of what it calls Autonomous IT, blending endpoint management, exposure management and security operations into a single platform. For enterprise IT and security leaders weighing up how to consolidate fragmented tooling,

When an IT incident strikes, every minute of downtime carries a cost: lost revenue, frustrated users, and pressure on teams who are often working without the right tools to respond quickly or consistently. For many organisations, incident response still relies on a patchwork of ITSM ticketing systems, messaging channels, and manual escalation processes that were never designed for real-time coordination. The result is slower resolution, inconsistent communication, and post-in

Organisations deploying AI at scale are facing a question that did not exist five years ago: how do you govern something that makes decisions, produces outputs, and influences outcomes in ways that are not always predictable or explainable? The EU AI Act has moved from regulation in principle to regulation in practice, and boards, risk committees, and regulators are all asking harder questions about how AI models are validated, monitored, and controlled. For many enterprises,

Controlling who can access what - and proving it - has moved from a back-office IT concern to a board-level priority. Security breaches, regulatory mandates such as NIS2 and DORA, and the rapid expansion of cloud, hybrid work, and third-party ecosystems have made Identity and Access Management one of the most scrutinised technology investments an organisation can make in 2026. AI-driven threat actors and the explosion of machine identities are accelerating demand further, pus

The endpoint management market has changed significantly. What began as unified device management has evolved into a converged IT operations and security capability, where the best platforms now deliver real-time visibility, AI-driven automation, vulnerability management, and security operations integration alongside traditional patch and configuration management. The consequence for buyers is that the platform decision carries broader architectural implications than it once
