Frequently asked questions

Frequently asked questions

From risk assessment to rapid response - we’re with you every step of the way.

At what stage should we bring in Security Architecture services?

The best time to assess security controls is at the beginning of any major project or transformation. That said, we can still evaluate and reinforce security within existing systems if you've already launched.

How does a Security Architecture review differ from pen testing?

Pen tests assess the security of what's already in place. Security Architecture helps prevent those flaws to begin with by designing systems securely from the start�moving you closer to your ideal security posture.

What is Security Architecture and why is it important?

Security architecture is the blueprint that shapes how your organisation protects its digital assets. By embedding security principles into system design, it ensures that your technology environment is built to resist threats - not just patched after the fact.

Who gets the most out of security architecture reviews?

CISOs, CTOs, IT leaders, and development teams involved in system design, migrations, or security framework alignment (e.g. ISO 27001 or ISM) should consider a structured review to ensure secure foundations.

Will you partner with our internal teams?

Absolutely. We work closely with your in-house architects to provide security leadership, deep technical guidance and practical implementation support.
