“Cybersecurity” and “information security” are often used as if they mean the same thing. They are closely related, and good organisations need both, but they are not interchangeable. Understanding where they differ, and where they overlap, helps you protect your business properly rather than leaving gaps that attackers and accidents can exploit.

In this article we break down what each term actually covers, why the distinction matters, and how to strike the right balance for your organisation.

What information security and cybersecurity mean for your organisation

The simplest way to tell them apart is to look at what each one protects.

Cybersecurity protects your critical data and systems against digital threats, particularly threats from outside the organisation. Cybersecurity professionals make sure that digital information is only accessible to authorised people, keeping attackers, malware, and unauthorised users out.

Information security is broader. It protects information of every kind, digital and physical, against unauthorised use, access, alteration, or deletion. A printed contract in a filing cabinet, a conversation in a meeting room, and a customer database in the cloud all fall under information security.

In short: cybersecurity is concerned with the digital world, while information security covers all of your information regardless of the form it takes.

The core difference, explained

At Rootsec, our work sits firmly on the technical, cybersecurity side. We focus on digital assets: data, laptops, mobile devices, systems, API connections, user accounts, and everything else that lives in or connects to your network.

Information security is built around three principles, often called the CIA triad:

  • Confidentiality — information is only available to those who are authorised to see it.
  • Integrity — information stays accurate and complete, and is not altered without authorisation.
  • Availability — information is accessible to the right people when they need it.

These principles apply to all information, including the non-digital kind. Cybersecurity does not concern itself with physical materials such as paper records or building access; information security does. That is the heart of the difference: cybersecurity is one essential discipline within the wider field of information security.

Why the difference matters today

The way we work no longer stops at the edge of the office. Teams operate across cloud platforms, mobile devices, home offices, and partner systems, and digital activity routinely crosses traditional organisational and geographic boundaries. Data moves between SaaS applications, third-party APIs, and personal devices, often without anyone consciously deciding it should.

This is why a purely perimeter-based mindset no longer holds up. There is no longer a single “inside” to defend. Protecting your organisation now means securing data and systems wherever they happen to be, for a workforce that may be anywhere. Cybersecurity gives you that digital protection, while information security ensures nothing falls through the cracks, including the risks that have nothing to do with technology.

Treating the two as one and the same is where organisations get caught out. Invest only in cybersecurity tooling and you may still leak sensitive documents, mishandle supplier data, or fail when a key system goes down. Focus only on policy and governance, and you leave the technical doors unlocked.

Finding the right balance is essential

Technology on its own will never be enough. As we like to put it: you can’t install a firewall on an employee. The strongest technical controls in the world can still be undone by a single click on a convincing phishing email.

Getting it right means combining solid cybersecurity with sound information security practice. That includes:

  • Business continuity — being ready to keep operating, and to recover quickly, when something goes wrong.
  • Security awareness — helping your people recognise and resist threats, so they become a line of defence rather than a weak point.
  • Vendor and supplier management — making sure the third parties you rely on handle your data as carefully as you do.

When cybersecurity and information security work together, you protect not just your systems, but your business as a whole. If you’re not sure where your current gaps are, a structured security assessment is the most reliable way to find out, mapping your real risks across both the technical and organisational sides before they become incidents.

The goal isn’t to chase every buzzword. It’s to understand what you’re protecting, who you’re protecting it from, and how the pieces fit together, so you can put your effort where it actually counts.
