The Best Cloud Security Solutions

Cloud security has moved from a technical concern to a business-critical risk area for UK organisations.

As more UK businesses rely on Microsoft Azure, AWS and Google Cloud, the nature of security risk has changed. The cloud platforms themselves are highly secure, but simple issues like incorrect settings, too many user permissions, and limited visibility remain the most common causes of cloud security incidents. In the UK, these problems can quickly lead to UK GDPR exposure, Cyber Essentials failures, cyber insurance issues and operational disruption.

As a B Corp Certified, cyber-focused service provider, Optimising IT prioritises cloud security that is not only effective, but ethical, transparent and aligned with long-term business resilience.

Why Cloud Security Matters

Cloud environments rarely fail on their own – problems usually arise when responsibility is misunderstood.

Under the shared responsibility model, cloud providers secure the underlying systems, but UK organisations remain responsible for how they use the cloud, including:

• Protecting personal and business data under UK GDPR and the Data Protection Act 2018
• Ensuring cloud services are set up securely
• Controlling who can access systems and data
• Monitoring activity and responding to security incidents

This reflects NCSC guidance, which consistently highlights misconfiguration and compromised user accounts as the most common cloud security risks facing UK businesses.

When cloud security goes wrong, the consequences often include:

• Regulatory investigation or fines
• Difficulties making cyber insurance claims
• Loss of customer trust
• Business downtime or disruption

The right cloud security approach helps UK organisations reduce these risks without slowing the business down.

Core Categories of Cloud Security Solutions

Modern cloud security is not a single product – it’s a layered approach. Most organisations will use a combination of the following.

Cloud Security Posture Management (CSPM)

Cloud Security Posture Management (CSPM) monitors cloud environments to detect misconfigurations, excessive permissions and compliance gaps with standards such as UK GDPR and Cyber Essentials. It helps prevent common risks like exposed storage and insecure access controls, while supporting NCSC-aligned cloud security best practices.

Cloud Workload Protection Platforms (CWPP)

Cloud Workload Protection Platforms (CWPP) secure workloads including virtual machines, containers and serverless applications. They provide runtime protection, malware detection and vulnerability management, making them essential for UK organisations running sensitive workloads in public cloud environments.

Cloud Access Security Brokers (CASB)

Cloud Access Security Brokers (CASB) provide visibility and control across SaaS platforms such as Microsoft 365 and Google Workspace. They manage data access, reduce shadow IT risk and help protect regulated data in remote and hybrid UK workforces.

Identity, Zero Trust & SASE

Identity is the primary attack vector in modern cloud environments. Cloud security strategies now focus on Identity and Access Management (IAM), Zero Trust Network Access (ZTNA) and Secure Access Service Edge (SASE), aligning with NCSC Zero Trust principles and UK compliance expectations.

CNAPP: A Consolidated Approach

Cloud-Native Application Protection Platforms (CNAPP) combine CSPM, CWPP and compliance reporting into a single platform. They simplify multi-cloud security management and reduce operational overhead for UK IT teams.

Leading Cloud Security Platforms Used in the UK

Rather than ranking tools, it’s more useful to understand what each platform is best at.

Microsoft Defender for Cloud

A strong option if you’re already invested in Microsoft Azure and Microsoft 365, helping you spot risky settings and security gaps.

Avanan Advanced Protect (Check Point)

A cloud-native security solution that protects Microsoft 365 and Google Workspace from phishing, malware, malicious links and account takeover attempts, integrating directly with SaaS platforms without disrupting users.

Huntress (Managed Detection & Response for Cloud & Identity)

Huntress provides 24/7, human-led monitoring for cloud identities and security logs, detecting identity-based attacks in Microsoft 365 and delivering compliance-ready visibility without the complexity of running an in-house SOC.

Acronis (Backup & Cyber Resilience)

An enterprise-grade backup and recovery platform offering ransomware protection, flexible cloud and local storage, and rapid system restoration across hybrid and cloud environments.

Wiz

Fast to roll out and gives clear visibility of cloud risks without installing software on every server, making it popular with lean teams.

Check Point CloudGuard

Good for keeping cloud configurations secure and compliant, especially in hybrid environments (a mix of cloud and on-prem).

CloudAlly (Microsoft 365 & Google Workspace Backups)

Automated, encrypted daily backups for Microsoft 365 and Google Workspace with unlimited retention and point-in-time restores, supporting data protection, business continuity and GDPR readiness.

Fortinet Cloud Security

Combines cloud security with network protection (like firewalls and secure connectivity), often used during traditional infrastructure-to-cloud transitions.

Zscaler

A leader in secure access for remote and hybrid teams, based on a “never trust, always verify” approach to user access.

All of these platforms are available in the UK and EMEA, support UK data residency, and are commonly used to help organisations meet Cyber Essentials Plus, ISO 27001 requirements, and NCSC cloud security guidance – priorities for many UK businesses.

Cloud-Native vs Third-Party Tools: A UK Perspective

AWS, Azure and Google Cloud all provide strong native security controls – and UK organisations should absolutely use them.

However, on their own, these tools can struggle with:

• Seeing risks across more than one cloud platform
• Producing clear compliance reporting
• Prioritising which issues matter most

For most UK organisations, the most effective approach is:

1. Cloud-native tools for basic protection
2. Third-party platforms for visibility, governance and advanced threat detection

This blended model aligns with NCSC guidance and reflects how cloud security is assessed during UK audits and insurance reviews.

How UK Organisations Should Choose the Right Cloud Security Solution

When Optimising IT works with clients on cloud security, we focus on four practical questions:

1. What does your cloud environment actually look like?
   Single cloud, multi-cloud or hybrid? Infrastructure-heavy or SaaS-led?~
2. Where are your biggest risks today?
   Identity sprawl, misconfiguration, lack of monitoring, compliance pressure?
3. What can your internal team realistically manage?
   Tools that generate noise but lack context rarely succeed.
4. How does this support UK compliance and resilience goals?
   Including UK GDPR accountability, Cyber Essentials and insurance requirements.

Cloud Security in a UK Compliance Context

For UK organisations, cloud security must support:

• UK GDPR and the Data Protection Act 2018
• Cyber Essentials and Cyber Essentials Plus
• NCSC cloud security principles
• Any industry-specific regulatory requirements

Cloud security tools play an important role in showing that appropriate technical and organisational measures are in place – particularly where personal or sensitive data is stored in the cloud.

How Optimising IT Supports Cloud Security

Technology alone does not deliver cloud security.

At Optimising IT, we help UK organisations:

• Assess their current cloud security risks (against NCSC and UK regulatory expectations)
• Design security approaches aligned to real business needs
• Implement and optimise cloud security platforms
• Integrate cloud security with wider cybersecurity strategies
• Support Cyber Essentials and Cyber Essentials Plus readiness
• Provide ongoing monitoring, guidance and remediation support

Final Thoughts

The best cloud security solution isn’t just about buying into the biggest platform – it’s about making the cloud work securely for your organisation.

If you’re unsure whether your current cloud security approach is right for you, an independent review is often the most effective starting point.

If you’d like to discuss your cloud security posture or understand what’s right for your organisation, Optimising IT can help.
