This is a complicated topic. It made be worth reading a quick definition before we move on:

What is cyber security?

Cyber security refers to the practice and techniques used to protect computers, networks, programs, and data from unauthorised access, attacks, damage, or theft. It encompasses a broad range of measures, tools, and processes designed to safeguard digital information and assets from cyber threats such as viruses, malware, ransomware, phishing attacks, and hacking.

Cyber security is crucial for individuals, companies, and governments alike, as it protects sensitive information, maintains privacy, and ensures the integrity and availability of data.

A prominent example of a UK-based cyber security startup is Sophos. Sophos offers a wide range of products and services designed to provide comprehensive protection against a variety of cyber threats.

Their solutions include endpoint protection, network security, cloud security, and encryption, catering to businesses of all sizes. Sophos is known for its innovative technologies, such as artificial intelligence-driven protection mechanisms, and its ability to offer unified solutions that simplify complex security environments.

Understanding Cyber-Security Investors

For Cyber-Security funding, differentiate clearly between angel investors and venture capitalists (VCs). Cybersecurity angels usually possess direct industry experience, investing personal wealth in startups at early stages. Cybersecurity VCs are structured firms backing companies that demonstrate market-ready solutions.
