Cloud computing has become a game-changer for modern businesses thanks to the scalability, flexibility, and cost savings it brings to the table.
But with this convenience come many critical risks—data breaches, the inability to deploy new services faster due to security concerns, non-compliance with data protection laws, and more.
Sensitive information stored in the cloud can be a gold mine for cyber criminals constantly detecting new vulnerabilities to exploit.
In addition, regulators set strict rules around how companies collect, store, and use personal data. Violators can face fines of up to 4% of their global annual revenue or €20 million — whichever is higher. That’s how Amazon was hit with an $877 million fine in 2021 for alleged GDPR violations.
So here we face it: while the cloud is meant to let businesses quickly adjust to new market demands, poor security measures can become a significant roadblock, preventing you from taking advantage of all technology’s potential benefits.
The risks can be far too complex to handle on your own. Investing in professional cybersecurity cloud services is an absolute necessity in this case. That’s why we’ve prepared this list of the top cloud security companies to help you stay ahead of evolving threats while maximizing your cloud’s agility.
