Newest courses
Cloud & Container Security
Blockchain & Smart Contract Security: Audit Solidity Code
Smart contracts are money that runs itself — and a single unchecked external call can drain a treasury in one block.
Cloud & Container Security
Kubernetes Security: Harden Production Clusters
A default Kubernetes cluster is a flat network where every pod can talk to every other pod and half of them run as root.
Blue Team & SOC
Security Automation with SOAR & Python
Most SOC burnout is not caused by hard problems — it is caused by the same easy problem arriving four hundred times a day.
Compliance & GRC
Linux Server Hardening: CIS Benchmarks in Practice
The CIS Benchmark for Linux is hundreds of pages of controls that nobody reads twice.
OT, ICS & IoT Security
IoT Security: Hacking & Hardening Connected Devices
An IoT product is four attack surfaces wearing one plastic shell: hardware, firmware, radio and cloud.
AI Security & Governance
MITRE ATLAS: Securing AI Systems Against Adversarial Attacks
ATT&CK gave defenders a shared language for network intrusions.
From the blog
-
How to study for Security+ without memorising a glossary
SY0-701 rewards understanding scenarios more than reciting definitions. Study accordingly.
-
Breaking into cybersecurity in 2026: what actually moves the needle
The entry-level market is crowded and the advice is contradictory. Four things still separate candidates who get hired.
-
CIS Benchmarks are a build standard, not a document
Hardening that is applied once and never enforced is hardening that lasted about a fortnight.
-
A connected device is four attack surfaces in one plastic shell
Hardware, firmware, radio and cloud. Miss any one of them and the product is not assessed.
-
In OT, availability is safety and patching is a negotiation
Industrial security is not enterprise security applied to strange hardware. The priorities are inverted.
The Nexus Signal
One cybersecurity briefing a week
Threat landscape, regulatory movement and one practical fix. Free, and short enough to actually read.
