Is it Cyber Security or Cybersecurity? Expert Weighs In.


Updated on:

Cybersecurity has been a buzzword for several years now, and we see it being thrown around quite a lot. But here’s something we don’t talk about enough – the spelling of the word itself. Is it Cyber Security or Cybersecurity? It may seem trivial, but it’s an important question to answer, especially for someone who spends their entire day talking about cybersecurity. As someone who works in the industry, I get asked this question a lot, and I’d like to weigh in and share my insights.

So, let’s dive into this seemingly trivial yet important topic and explore why the spelling matters. But before we move forward, let me introduce myself. I’m a cybersecurity expert, and I’ve been working in this field for over a decade now. I’ve seen all kinds of cyber threats, from minor data breaches to full-scale cyber warfare. Through my experience, I’ve come to realize that when it comes to cybersecurity, the smallest details can have the most significant impact.

Now, let’s get back to the real issue at hand – Cybersecurity or Cyber Security? Trust me; there’s more to it than meets the eye.

Is it cyber security or cybersecurity?

Whether you use “cybersecurity” as one word or “cyber security” as two words, the meaning remains the same. Cybersecurity refers to the protection of digital devices, networks, and information systems from unauthorized access, theft, or damage.

Here are some key points to keep in mind about cybersecurity:

  • Cybersecurity is becoming increasingly important due to the rise of cyberattacks that can cause significant financial loss and reputational damage to businesses.
  • Cybersecurity includes a range of practices, such as implementing firewalls and antivirus software, training employees on how to identify and respond to threats, and regularly updating software and systems to address vulnerabilities.
  • Cybersecurity threats can come from a variety of sources, including hackers, malicious software (malware), phishing attacks, and insider threats.
  • Effective cybersecurity requires a combination of people, processes, and technology to protect digital assets and ensure the confidentiality, integrity, and availability of information.

  • ???? Pro Tips:

    1. Stay consistent: Choose one spelling and stick with it throughout all your documents, presentations, and communications. Consistency minimizes confusion and makes it easier for your audience to understand your message.

    2. Check your sources: When doing research on cyber security, make sure to use reputable sources. News outlets, government websites, and cybersecurity experts are great sources to rely on. Avoid sources with questionable credentials or biases.

    3. Be clear in your communication: It’s important to be crystal clear in your communication, especially when it comes to technical information. Use plain language, avoid acronyms, and always define any technical terms that may be unfamiliar to your audience.

    4. Keep up-to-date: Cybersecurity is an ever-evolving field, with new threats presenting themselves regularly. Stay up-to-date with the latest developments in the field, including new threats, vulnerabilities, and best practices.

    5. Consider your audience: Consider who your audience is when communicating about cyber security. If your audience is not technical, avoid jargon and technical terms. Instead, focus on explaining threats and prevention measures in an accessible and understandable way.


    The world of cybersecurity is constantly evolving, and with it, so is the terminology. With different variations and spellings of the word, it can be confusing for professionals, industry-wide. Is it “cybersecurity” or “cyber security”? Many wonder if the difference in spelling has any significant impact or if it is just a matter of preference. In this article, we will explore the history and evolution of the spelling of cyber security terminology and its impact on industry standards.

    History of cyber security terminology

    The earliest use of the term “cybersecurity” can be traced back to the 1980s when computer security became a concern. As technology continued to advance, the term evolved and was used to refer to the protection of computer systems from external threats such as viruses, malware, and hacking attempts. The term “cyber security” also became more widespread as the internet grew in popularity and digital communication became common.

    The American style: cybersecurity

    In the United States, cybersecurity is the more commonly used spelling and is generally found as a single word. This style is often seen as more concise and simple, making it easier for people to understand and use. It is also the preferred spelling of many government agencies, including the Department of Homeland Security.

    Key point: The American style of spelling cybersecurity is generally more popular, using one word instead of two.

    The British style: cyber security

    In the UK, the spelling of “cyber security” is often found as two words, “cyber” and “security.” This spelling is favored by editorial style guides such as The Economist and The Guardian. They believe that using two words maintains clarity and enhances the precision of the term.

    Key point: The British prefer to spell cyber security in two words, believing it enhances precision.

    Common usage and industry standards

    There is a lack of universal agreement on which spelling to use, and both are acceptable. However, the general consensus is that the spelling should match the convention used in the region where it is being used. Most industry-standard manuals and publications such as NIST SP 800-53, OWASP Top Ten Project, and ISO 27001 spell it as cybersecurity.

    Bullet points:

  • Industry standards, like NIST SP 800-53, generally prefer “cybersecurity.”
  • The convention in the region where it is being used should be followed.

    Practical considerations for choosing a spelling

    When choosing which spelling to use, it is essential to consider the context in which it will appear. In a headline or title, a single word spelling might read more smoothly, whereas in technical or scientific writing, a hyphenated or two-word spelling might be more appropriate. It is also important to keep in mind who the target audience is, as different regions or industries might have a preferred spelling.

    Bullet points:

  • Consider the context in which the spelling will appear, such as headlines or technical writing.
  • Keep the target audience in mind while choosing a spelling.


    In conclusion, the spelling of “cybersecurity” or “cyber security” is not a matter of right or wrong. Both spellings are acceptable, and the preference depends on the region or industry. The American style of spelling cybersecurity is more concise and often preferred in government documents, whereas the British style that spells it as two words is seen as more technically precise in some editorial circles. When choosing which spelling to use, it’s important to consider the context, target audience, and regional preferences. Ultimately, the goal should be to communicate effectively, regardless of how cybersecurity is spelled.
