A postmortem is easy to hold and hard to make useful. The meeting happens, a document is written, four action items are recorded, and six months later the same failure occurs and somebody finds the old document while searching for something else. The word “blameless” gets most of the attention in discussions of this,...
Server Security
Guides, tutorials, and checklists on server security, covering hardening, attack-surface reduction, firewalls, auditing, and protecting Linux servers.
Supply chain security sounds like a problem for organisations with a security function, and the framing is misleading. A small team running a handful of services typically depends on hundreds of packages it has never read, pulled at build time from registries it does not control, executing installation scripts on...
An uptime SLA looks like a promise and behaves like a refund policy. Suppliers know this. Customers frequently do not, and sign a service level agreement believing they have bought availability when what they have bought is a small discount in the event they do not get it. That is not necessarily a bad deal. It is a...
Disaster recovery in a small team is usually one line in a document nobody has opened: backups are enabled. That statement is true and it is not an answer, because it says nothing about how old the data would be, how long the restore takes, or whether anyone has ever performed one. The gap between having backups and...
Migrating to Cloudflare Zero Trust is a critical modernisation step for enterprises looking to replace outdated corporate VPNs in 2026.

Data breaches expose companies to hefty fines under compliance rules, alongside severe damage to brand reputation. Regular security audits guard your business against...
Calculating the cost of penetration testing in the UK is a vital compliance task for enterprises planning cyber security audits in 2026.

A server security audit is a systematic review of a server’s exposure and configuration to find where an attacker could get in and what they could do once inside. If you have been asked to commission one, or you want to run an internal review, this guide explains exactly what a thorough audit examines and why each area...
A default Linux install is convenient, not secure. Hardening is the process of reducing a server’s attack surface and tightening its configuration so that the inevitable probing from the internet finds nothing easy to exploit. This guide covers the hardening steps that matter most in 2026, in a sensible order of...
