Our approach


Cloud security is now a fundamental part of business as usual. The cloud is everywhere, being universally adopted at speed across different industries and types of organization. This speed has led to growth and opportunity, but not without creating new challenges for the security teams tasked with minimizing the cyber threats to an environment with a totally new rulebook.

Our cloud approach is holistic. As well as providing cloud-specific solutions for organizations transitioning or maintaining their cloud environment, we apply a cloud-first mindset across the consultancy. This takes the shape of a central cloud team that delivers cloud-specific work and advises across all other engagements.

Our specialist cloud security cconsultants possess broad and varied experience of tackling the challenges related to adopting and fostering cyber security in your cloud environment. We have helped clients predict, prevent, detect, and respond to cyber security attacks in Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS) cloud implementations, across multiple providers, at all stages of adoption.

Services & solutions

The growing cloud capability we offer spans attack detection, incident investigations and response, penetration testing, cyber defense, and research. Our approach to cloud security consulting is delivered in partnership with organizations, accounting for their specific needs and desired outcomes, including:

Reducing vulnerabilities introduced during the development phase, by training developers to build secure infrastructure-as-code.

Ensuring that cloud environments are secure-by-design, by assessing proposed architecture before and throughout development.

Providing assurance that deployment is secure through ongoing hardening, by assessing existing, live cloud environments and the critical services within them.

Developing a culture of “building in” security to mitigate risks and exposures.

Reducing the impact of a compromise by preparing cloud-based attack detection and Digital Forensics & Incident Response (DFIR) measures.

How WithSecure™ can help.

50% of the incidents investigated on behalf of our clients between 2020 and 2021 involved cloud technology. Cloud security is now everything, not an add-on, and our cloud team has influence across the entire consultancy.



We’ve supported clients across design, migration, configuration and hardening projects. We continue to develop crucial knowledge and threat intelligence as the number of cloud-based cyber security attacks we see increases.


Proven methodologies

We use systems and processes developed through real-world client engagements and research. These ensure that environments get fully and correctly assessed, and that no stone is left unturned, helping us provide stronger cloud security assurance.



We’ve designed and deployed custom tools to overcome specific technical challenges within AWS and Azure. These streamline and expedite assessment activities, leaving more time for consultants to find meaningful issues in the architecture, design, and data flows of platforms.
