Introduction

With cyber security threats continuing to evolve and adapt at lightening pace, adequate protection of organisational data is essential. There are many ways for organisations to ensure systems and data are protected – these include the implementation of security measures and controls. Cyber Essentials, Cyber Essentials Plus, and IASME Cyber Assurance are aimed at providing organisations with ways to implement security measures, but what’s the difference? In this article we explore the topic with a view to helping organisations gain more clarity and support decision making.

 

Cyber Essentials

Cyber Essentials is a UK government-backed scheme and the recommended minimum standard for organisations of all sizes. It’s an annual renewable certification scheme designed to protect organisations from the most common forms of internet-based cyber security threats. It focuses on just five (technical) controls. Cyber Essentials (Level One) involves implementing the required security controls and completing a questionnaire. Successful applicants are awarded a 12-month certificate, with eligible organisations also being able to opt in for free cyber insurance.

 

Cyber Essentials Plus

Cyber Essentials Plus (Level Two) has Cyber Essentials as a prerequisite and consists of a technical audit of an organisation’s IT systems, which verifies that the five technical controls are in place. It gives more assurance that organisations are protected from common forms of cyber threat and provides confidence that the security measures are operating effectively. The audit focuses on a sample of user devices and includes testing of servers, networking equipment, and cloud services. Successful applicants are awarded a 12-month certificate for Cyber Essentials Plus.

 

IASME Cyber Assurance

IASME Cyber Assurance goes beyond Cyber Essentials, being much broader and more comprehensive. It is aimed at making organisations more cyber resilient and references up to 65 security requirements. These requirements can be applied to organisations of all sizes, with the scheme having tailored solutions for organisations with less than 50 people. There are two levels for IASME Cyber Assurance, with Level One being a verified self-assessment and Level Two being an audit. Successful applicants are awarded a 12-month certificate, with the Level Two audit being required every three years. Cyber Essentials is a valid prerequisite for IASME Cyber Assurance.
