What Does Cloud Security Entail?

Cloud security is a niche within cybersecurity that is focused on keeping your systems, users, and data safe while your IT infrastructure is connected within or through a cloud environment.

Breaches of cloud security can lead to data leaks, third-party intrusions, and system takeovers, all of which may have serious legal, reputational, and financial consequences.

Securing a cloud environment involves a few different things. These include encryption, access controls, identity and access management, network security, threat detection and prevention, and incident response.

To maintain the highest levels of cloud security, organizations should undertake thorough threat assessments complete with penetration testing at regular intervals, ensure that staff are adequately trained, and have an incident response SOP in place.

These are all things a top cloud security company like Microminder can help you with.

How to Choose the Best Cloud Security Companies in the UK to Work With

We’ve just shared a list of the top 10 cloud security companies in the UK. The question you might now have, though, is which one should you work with? Here are some factors to consider:

Area of Expertise

Cloud security is a slightly broad field so you should evaluate potential cloud security providers by how well they match your needs. You can use this list as a guide and then get in touch with companies you’re interested in to learn more about what they do and how they work.


Cloud computing in general is a rapidly evolving field. This means the best experts have to engage in continued learning in order to stay abreast of best practices.


Cybersecurity firms generally charge different fees. You might find that larger companies may charge a lot more for the same service, which would be inefficient if you’re a smaller business on a budget. So as you sift through potential cloud security service providers, keep in mind that you might be able to get the same quality of service for much cheaper.

Getting Started With Cloud Security

Now that we’ve shared our compilation of the top cloud security companies in the UK along with some tips on how to pick the right company, you can go on and contact these companies to explore the ways they can help shore up your cloud protection.
