In short, both! The American style is “cybersecurity.” Britains like cyber security as two words.
Merriam-Webster only has “cybersecurity” as an entry, not the two-worded version.
Whichever spelling you choose to use, the meaning typically does not change. Both spellings of the word refer to the same things when communicating your thoughts.
Generally, it’s good practice to standardize your writing. Use one spelling and stick to it throughout your writing.
What Is Cybersecurity (Or Cyber Security)?
Cybersecurity is the protection of internet-connected systems.
- Data from physical and cyber crimes
Example Of “Cybersecurity” Being Used
The Cybersecurity and Infrastructure Security Agency (CISA) is a U.S. federal agency. It is an operational component under Department of Homeland Security oversight. CISA chooses to spell cybersecurity as a single word.
Clearly, the U.S. government has decided to use “cybersecurity.”
Examples Of The Word “Cyber Security” Being Used
Many other national cyber defense agencies choose to use the term “cyber security.”
- Canadian Centre for Cyber Security
- Cyber Security Agency (Singapore)
- National Cyber Security Centre (Ireland)
- National Cyber Security Centre of Lithuania
- National Cyber Security Centre (United Kingdom)
Remember, both terms work and are equally correct!
The spelling you choose to use may be dependent on where you live. If you work primarily in the U.S., it may be easier to use “cybersecurity.” That way, you appeal to the familiarity of the word as one word.
