This list compares top cloud security companies and services, with each provider’s location, cloud security services, industries and clients, for businesses that need help securing AWS, Azure, Google Cloud or hybrid environments.
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.

What Cloud Security Services Include
Cloud security providers protect the data, applications and infrastructure a business runs in public, private or hybrid clouds. The providers on this list offer a mix of these services:
Cloud security assessments and audits: reviews of cloud configurations, access controls and architecture against best practices and compliance standards.
Cloud penetration testing: simulated attacks on cloud workloads, APIs and applications to find exploitable weaknesses.
Monitoring, detection and response: continuous monitoring of cloud activity, with managed detection and response (MDR) and incident response when something goes wrong.
Compliance support: help meeting frameworks and regulations such as GDPR, SOC 2, ISO 27001, HIPAA or PCI DSS.
DevSecOps and secure migration: building security into development pipelines and cloud migrations from the start.
Cloud security platforms: software such as Wiz that scans cloud environments for vulnerabilities, misconfigurations and compliance risks.
Match your cloud platforms: confirm the provider has hands-on experience with AWS, Azure, Google Cloud or the mix you use.
Decide between a service and a platform: consulting and testing firms deliver audits and expert work, while platforms give your own team ongoing visibility. Many companies use both.
Check compliance experience: if you work in a regulated industry, ask which frameworks the provider has helped clients meet.
Look at location and coverage: a provider in or near your region can help with data residency rules, time zones and on-site work.
Ask for sample reports: a good test or audit report explains each risk clearly and gives practical steps to fix it.
Clarify ongoing support: find out whether the provider offers retesting, monitoring or a retainer after the first engagement.
Cloud security companies protect the data, applications and infrastructure that businesses run in the cloud. Their services include security assessments and audits, cloud penetration testing, monitoring and incident response, compliance support and secure cloud migration. Some, like Wiz, provide a software platform rather than consulting services.
How much do cloud security services cost?
The cost depends on the type of engagement, the size and complexity of your cloud environment, the number of accounts and applications in scope, and compliance requirements. One-off audits and penetration tests are usually priced per project, managed monitoring and response is billed as a monthly or annual subscription, and platforms are typically licensed by the number of cloud resources or workloads. Ask several providers for a scoped quote.
Which cloud security companies serve Europe?
Several providers on this list are based in Europe, including Atlant Security in Sofia, Sekurno and Datami in Tallinn, Black Bullet in Bucharest, Iterasec in Rzeszów and BreachLock in Amsterdam. IT Labs has offices in London and Noordwijk. Many US-based providers also serve European clients remotely.
