What is a Cybersecurity Consulting Firm?

A cybersecurity consulting firm is a team of professionals who offer recommendations and solutions to protect your organization’s systems and networks from cyberattacks. They evaluate your company’s computer systems for vulnerabilities to keep cyber criminals from gaining unauthorized access. Once vulnerabilities are identified, specialists recommend the best software solutions, integrate them, and monitor potential cyber threats.

Cybersecurity consulting firms also offer cybersecurity training for your employees to make them aware of common cyberattacks and can help prevent them from happening.

Cybersecurity vs. IT Security

Cybersecurity and IT security are often used interchangeably, but they differ. IT security, also known as information technology security, is focused on protecting the confidentiality, integrity, and availability of IT systems and data. IT security services include firewalls, antivirus software, and access controls to protect against unauthorized access.

Cybersecurity, on the other hand, is a broader term that includes IT security and the protection of all digital assets, including networks, systems, applications, and data, from attacks, misuse, or unauthorized access.

Simply put, IT security is a subset of cybersecurity covering a wide range of digital assets and threats. While both protect digital information, cybersecurity focuses more on the bigger picture of all digital assets, while IT security is more focused on protecting IT systems and data.

5 Types of Cybersecurity

Cybersecurity is a broad term that can be categorized into five distinct types:

  1. Critical Infrastructure Security: Critical infrastructure security ensures that a country or city’s systems, networks and digital assets are protected from cyber attacks.
  2. Application Security: Application security refers to developing and testing security features within your application. This prevents security vulnerabilities such as data manipulation and unauthorized third-party access.
  3. Network Security: Network security (read our article on what is network security) is a set of processes and strategies designed to protect your network from unauthorized threats and access.
  4. Cloud Security: Cloud security is a set of protective measures built to protect data and applications found on the cloud or the internet.
  5. Internet of Things (IoT) Security: IoT Security protects devices connected to the internet and their associated networks from potential cyber threats and vulnerabilities.
