Desucla's starting point
Desucla operates a platform supporting tax compliance across multiple jurisdictions and works with organisations that expect high confidence around information management.
Security was already an established consideration. The next step was to bring more structure to the existing work and achieve recognised, independently assessed standards.
From existing security work to a working security programme
YDC helped Desucla turn existing security considerations into a structured programme covering risk, controls, evidence and ongoing management.
What the engagement involved.
The outcome.
Desucla achieved Cyber Essentials, Cyber Essentials Plus and ISO 27001 certification. More importantly, the engagement established a working security management system behind those certifications. Risks are reviewed, responsibilities are understood, evidence is collected, controls are tested and security decisions have a clear place to live.
“Certification was a milestone. It was never intended to be the end of the work. We continue to work with Desucla as an ongoing security consultancy partner.”

Security assurance gets easier when the work joins up.
Cyber Essentials, Cyber Essentials Plus, ISO 27001, customer questionnaires and supplier reviews do not need to become separate programmes. YDC helps organisations build one sensible security system around the requirements that matter to their business.
