Essential Security + Exam Guide: For the CompTIA SY0-701 Exam

by Phil Martin

The CompTIA Security+ certification provides a foundational understanding of cybersecurity principles and practices, covering the essential knowledge and skills needed to secure networks, systems, and data. The certification is vendor-neutral and is often recommended as an entry-level credential for IT security professionals.

The Essential Security + Exam Guide—updated for 2026—covers all material for the CompTIA SY0-701 Exam. Instead of the usual $100 words and run-on sentences that technical guides often use, it provides visual diagrams and illustrations to make the content easier to understand. In fact, the illustrated figures by themselves cover 75 percent of the exam's subject matter. Following Martin’s light-hearted approach to technical topics, interesting examples and stories are used to drive home lessons based on real-world experience.

About the author

I grew up in the creative cauldron of nineties Manchester when Madchester rocked the charts and the Hacienda ruled clubland. The city has shaped me as a writer. I write thrillers and crime based on the fine folk of Manchester and Salford. The Little Girl Lost trilogy has however developed into an international thriller taking in Manchester, Morocco, London, Barcelona, Monza, Zurich, Moscow, Chechnya, Batumi and... Milton Keynes.
